PageSpeed Release Notes
Release <IP_ADDRESS>-beta
This release was made November 8, 2017.
New Features
- Content Security Policy Support
- Opt-in feature enabling optimizations to adapt to Content Security Policies.
- Support specifying a Redis Database
- It is now possible to specify which database will be used when configuring Redis as a cache.
- Sync with WebP change in Chromium
-
The webp decoder is being updated to correct an issue where it can't play an animation exactly once, and requires an encoder update.
Background: - Log errors if serf error rate seems too high.
- When over 50% of http fetch attempts inside a 30-minute period fail, pagespeed will now emit an error entry to the logs.
- Off has been replaced by Standby
- In standby mode PageSpeed is off, except it serves .pagespeed. resources and PageSpeed query parameters are interpreted. This is equivalent to "off" in mod_pagespeed. Previously, ngx_pagespeed had no equivalent. With this change, "off" in mod_pagespeed is deprecated, and "standby" should be used instead.
- Allow UrlValuedAttribute:image on elements with children
- Tags that have children are now considered acceptable targets for image optimization.
Deprecations
- Standby has replaced Off
- Pagespeed off has been deprecated and replaced with pagespeed standby.
- Ubuntu 12.04 end of life
- The platform used to build .deb files has moved to Ubuntu 14.04. This introduced a dependency on a glibc version which is not compatible with Ubuntu 12.04. Building from source is still possible.
Issues Resolved
Issues Affecting both Nginx and Apache
- #1207 Don't emit type=text/javascript on script tags.
- #1609 Specify which Redis DB to use when confiuring Redis as a caching backend.
- #1153 Pedantic filter should prevent inlining CSS into the body.
- #1538 CSS Minification - 0 followed by a unit is rewritten to 0 without a unit .
- #1572 CSS minifier breaks unicode-range values.
- #1585 Don't special-case sending webp to PSI.
- #1553 Debug builds may abort() when revalidating expired output resources.
- #1418 LoadFromFileCacheTtlMs is not honored after first request.
- #1382 In amp pages inline_google_font_css must be disabled.
- #1496 Attempting to extend cache for SVGs returns bad headers/content.
- #1405 ERROR: Invalid inlined_image_type in cached_result.
Issues Affecting only Nginx
- #1380 Nginx worker 100% cpu usage (spinning on write returning EAGAIN).
- #1375 Don't respond with an entity body to HEAD requests for html.
- #1465 Fix ignored return code in ps_simple_handler().
Release <IP_ADDRESS>-stable
This nginx-only release made September 28, 2017. As of nginx 1.13.4 building the module would fail. This release resolves the problem.
Issues Affecting Nginx
- Issue 1451 nginx 1.13.4 "ngx_http_core_try_files_phase" was not declared in this scope
Release <IP_ADDRESS>-stable
This release was made June 19, 2017. It is a clone of the <IP_ADDRESS>-beta release.
Release <IP_ADDRESS>-beta
This nginx-only bug-fix release was made December 15, 2016. It allows the
precompiled PSOL library to be used with nginx's --with-debug
.

Release <IP_ADDRESS>-beta

New Features
- Redis Support
- Support for Redis Cache and Redis Cluster as external caches.
- Add preload hints
- This is a new filter, off by default, that looks for declaratively included stylesheets and javascript to figure out the page's dependencies, and inserts preload headers so the browser can start loading them immediately.
- Optimize Srcsets
-
PageSpeed now optimizes images referenced in
srcset
attributes. - Set
s-maxage
-
To prevent CDNs and other shared caches from caching the unoptimized
version of resources for a long time, PageSpeed now
adds
s-maxage=10
to the cache-control headers for unoptimized resources that we intend to optimize in-place. - Allow combining stylesheets with IDs
-
PageSpeed would previously refuse to combine stylesheets with IDs, which
interacted poorly with WordPress and other content management systems
putting IDs on all their CSS files. Setting
PermitIdsForCssCombining
wildcards allows you to indicate to PageSpeed which IDs on CSS files are ok to ignore. -
FinderPropertiesCacheExpirationTimeMs
- Configures the length of time the prioritize_critical_css beacons are valid.
-
AddResourceHeader
- Allows setting headers on optimized resources for CORS support.
- Shared Memory Cache Checkpointing
- The shared memory metadata cache now checkpoints to disk every few minutes instead of writing all changes through as they happen. In our testing this improved performance on workloads that require many metadata writes by 21%.
Deprecations
- Support for disabling
InheritVHostConfig
-
For historical reasons, mod_pagespeed on Apache doesn't respect the global
PageSpeed configuration when interpreting VHost configuration. Since
1.1 in 2012, however, it has shipped with a default configuration file
that fixed this by setting
InheritVHostConfig
to "on". For the minority of installations that don't use the default configuration file, or explicitly setInheritVHostConfig
to "off", PageSpeed will now log an error on startup warning that the setting will soon change. With the next major version releaseInheritVHostConfig
will be forced to "on". - Centos 5 Support
- CentOS 5, released in 2007, goes end-of-life at the end of March 2017. The 1.12 rpm packages are for CentOS 6 and later, and will fail to install on CentOS 5. The stable release track, 1.11, continues to support CentOS 5.

This release targets users on mobile devices and low-bandwidth networks by adding Save-Data support. Save-Data is a new Client Hint that allows site visitors to indicate that they would prefer lower-quality resources in order to save data. Sites are most likely to see requests to save data today from visitors who have turned on Data Saver mode in Chrome or the equivalents in Opera and Yandex Browser, often because they're on slow or expensive connections. Now, with 1.11, when such a user comes to your site asking it to save data, mod_pagespeed will compress images to a lower quality level than it would typically, decreasing their size further at the cost of slightly more image distortion.
New Features
- Save-Data Support
- Serve more thoroughly compressed images to browsers that request lowered data usage via client hints.

Release <IP_ADDRESS>-stable
This security update release was made March 28, 2016.
All previously released versions of PageSpeed are vulnerable to CVE-2016-3626. This permits a hostile third party to trick PageSpeed into making arbitrary HTTP requests on arbitrary ports and re-hosting the response, allowing cross site scripting. If the machine running PageSpeed has access to services that are not otherwise available, this can reveal those resources.
Users are strongly encouraged to update immediately. If this isn't possible, a workaround is available.

Release <IP_ADDRESS>-stable
This security update release was made February 3rd, 2016.
All previously released versions of PageSpeed are vulnerable to HTTPS-fetching vulnerability CVE-2016-2092. This permits a hostile third party who can man-in-the-middle the connection between PageSpeed and an HTTPS server to substitute arbitrary content in responses. PageSpeed is not vulnerable in its default configuration, but several filters and options can enable this vulnerability. See our CVE-2016-2092 announcement for more details and workarounds.
LibPNG has been updated to 1.2.56. Previous versions had an out-of-bounds read (CVE-2015-8540) which a hostile third party could trigger if they were in a position to supply images for PageSpeed to optimize.
The latest version of Chrome for iOS (M48) switched to the WKWebView for rendering, dropping support for WebP images. Prior versions of PageSpeed will send WebP to Chrome on iOS, giving broken images to these users. While this isn't a security vulnerability, this is a serious enough breakage that we're including it in this security release.

Release <IP_ADDRESS>-beta
This release was made December 14th, 2015.
With the 1.10 release we have several high-impact features to share. We're
most excited about Responsive Image
Support, which delivers high resolution images to high pixel-density
screens by automatically generating html5 srcset
attributes for images. Other big changes
include Caching Gzip Output, which lets us
run gzip at the most aggressive encoding
level, Remote Config,
which lets you load additional configuration over the network, and
converting Animated GIF to WebP, which reduces the size of animated GIFs by 65%.
New Automatically Enabled Features
- Cache Gzip Output
- Compress rewritten resources at the highest compression setting and store them compressed in cache.
- Insert Universal Analytics
- If enabled, the Insert Google Analytics filter will now insert Universal
Analytics (
analytics.js
) instead of the legacyga.js
. This should have no impact on reporting, and gives you access to the benefits of Universal Analytics. - Fetch resources over HTTPS
- HTTPS fetching is now enabled in the default configuration.
- Switch to new JS Minifier
- The JavaScript minifier introduced in 1.8 is now the default.
- Add PageSpeedNoop Query Parameter
- Add query parameter for cache busting.
- HTML5-compliant attribute names
- HTML5 requires all custom attributes to be prefixed
with
data-
, and with this release PageSpeed generatesdata-pagespeed-foo
attributes. Old-stylepagespeed_foo
attributes are still accepted.
New Opt-In Features
- Remote Configuration
- Fetch additional configuration directives over HTTPS.
- Responsive Image Support
- Make images responsive by adding
srcset
attributes for different pixel densities. - Animated WebP
- Convert animated GIF to animated WebP for browsers that can render it.
-
Make
showads.js
Asynchronous - Convert the blocking
showads.js
snippet into the asynchronousadsbygoogle.js
snippet. - HTTP/2-specific configuration in ngx_pagespeed
- Allow configuring filters and sharding differently depending on whether the browser connection is HTTP/2.
- Request-specific downstream caching configuration
- Allow script variables in the downstream caching configuration. (Nginx only)
- Content Experiments
- Allow PageSpeed experiments to log data to a Google Analytics Content Experiment.

Release <IP_ADDRESS>-stable
This release was made Jun 17, 2015. It is a clone of the <IP_ADDRESS>-beta release.
Release <IP_ADDRESS>-beta
This security update release was made June 17, 2015.
In versions between 1.7 and <IP_ADDRESS>, PageSpeed was built with a version of OpenSSL that was vulnerable to the issues detailed in the June 11, 2015 security advisory. We have updated our crypto library to fix these issues. PageSpeed now builds with Google's BoringSSL, an OpenSSL fork which includes this fix, and is expected to be more stable in future.
In versions between <IP_ADDRESS> and <IP_ADDRESS> it was possible to cause a crash by requesting JavaScript source maps when source mapping had been turned off.
We recommend that all users upgrade. If this is not possible, however, the following workarounds are available:
- The OpenSSL vulnerability only applies if you have
FetchHttps
enabled and have configured PageSpeed to fetch HTTPS content over the open internet. DisablingFetchHttps
will prevent these crashes, but will also disable PageSpeed's optimizations for any content that must be fetched over HTTPS. - Set a
Request Option Override
token, and explicitly enableinclude_js_source_maps
. This makes it impossible for attackers to disable source maps and cause these crashes.
Issues Resolved
- Issue 1094 Source map can be requested with option disabled.
- OpenSSL Security Advisory [11 Jun 2015] Replace OpenSSL with BoringSSL.

Release <IP_ADDRESS>-beta
This release was made July 10, 2013.
New Features
- PageSpeed Console
- The PageSpeed Console monitors your installation's performance and links to general information on how to improve the performance.
- Supporting downstream caches
- Experimental feature for supporting caching proxy servers to allow HTML to be cached in these servers.
- dedup_inlined_images
- Filter that removes redundant inlined images and replaces them with JavaScript that loads all subsequent uses from the first.
- Randomly drop expensive rewrites
- To reduce processing load, PageSpeed can be configured to optimize the most frequently fetched resources, leaving infrequently fetched resources alone. This is accomplished by randomly dropping expensive (CSS and image) rewrites. Frequently fetched resources will have a higher probability of being rewritten than infrequently fetched resources. Over time, frequently accessed resources will be optimized and cached so a page will be fully optimized. Infrequently accessed pages will be left unoptimized or partially optimized, saving CPU time and cache space.
- DisableRewriteOnNoTransform
- Default on, but may be turned off to allow PageSpeed to rewrite
resources even if they have a
Cache-Control: no-transform
header. - Configuration defaults updated
- Starting in this release, we enable lossy image compression by default
and update several other default configurations values. Updates:
- Default AvoidRenamingIntrospectiveJavascript to on (was off).
- Default ImageInlineMaxBytes to 3072 (was 2048).
- Default CssImageInlineMaxBytes to 0 (was 2048).
- Default MaxInlinedPreviewImagesIndex to -1 = unlimited (was 5).
- Default MinImageSizeLowResolutionBytes to 3072 (was 1024).
- Default ImageRecompressionQuality to 85 (was -1 = lossless).
- Default JpegRecompressionQualityForSmallScreens to 70 (was -1 = lossless).
- Default WebpRecompressionQuality to 80 (was -1 = lossless).

Highlights
We have modified or added filters to do in-browser analysis of your pages and report the results back to PageSpeed, allowing it to further optimize the pages for subsequent visitors.
The new prioritize_critical_css filter instruments your pages to determine the CSS rules actually used to render them and inlines just those rules; this permits the browser to style the page without fetching external resources, which is especially important for mobile browsing where it can take hundreds of milliseconds to establish a fresh connection.
The inline_images, inline_preview_images, and lazyload_images filters now instrument the page to determine the images that are above the fold so as to optimize just them, thereby displaying what the user sees faster.
Support for Nginx.
New Features
- The lazyload_images filter now uses beacons to determine the above-the-fold images.
- The inline_preview_images filter now uses beacons to determine the above-the-fold images.
- The inline_images filter now uses beacons to determine the above-the-fold images; as this is a core filter, beacons will now be used if your RewriteLevel is CoreFilters and you have not explicitly disabled this filter and/or beacons.
- Beacon handling has changed so that by default they are now handled automatically - Apache no longer requires a Location directive although one can be used to disable beaconing.
New Filters
- prioritize_critical_css
- Inline only the CSS used by the page.
New Configuration Options
- CriticalImagesBeaconEnabled
- ImageJpegNumProgressiveScans
- ImageJpegNumProgressiveScansForSmallScreens
- WebpRecompressionQuality
- WebpRecompressionQualityForSmallScreens
Issues Resolved
- Issue 109 Make it easy to install on cPanel EasyInstall.
- Issue 508 Large numbers get rewritten to scientific notation.
- Issue 672 Disable setting more than one thread for memcached.
Release <IP_ADDRESS>-stable
This release was made May 3rd, 2013. It is a clone of the <IP_ADDRESS>-beta release.
Release <IP_ADDRESS>-beta
This release was made April 4th, 2013. It fixes a bug that caused
the convert_meta_tags
filter to incorrectly propagate
XHTML mimetypes from some <meta http-equiv>
elements
to HTTP headers.
Release <IP_ADDRESS>-beta
This release was made April 3rd, 2013.
New Features
- In-Place Resource Optimization
- PageSpeed can now optimize resources accessed directly from their original URLs, not just those rewritten with the PageSpeed URL format. This can be useful for optimizing resources referenced from other sites and from JavaScript.
- Preserve URLs
- Prevents PageSpeed from rewriting URLs in HTML files and instead relies on In-Place Resource Optimization for resource optimization. This can be useful when it is necessary to be conservative about altering the pages that PageSpeed serves, such as in a forward proxy.
- Shared Memory Metadata Cache
- An in-memory cache that shares metadata entries between Apache processes on the same server. This can provide significant performance benefits.
- Client Options Header
- Support for a new request header that can be used to configure image optimizations.

- Lossless & transparent WebP support.
- PageSpeed can now take advantage of support for lossless & transparent WebP images in some newer browsers, which can provide smaller file sizes than PNG.
- Embedding configuration into resource URLs.
- You can now configure PageSpeed to embed image & CSS optimization settings in resource URLs. This is useful in multi-server setups where perfectly replicating configuration information may be infeasible.
- Better CDN support in MapProxyDomain.
- You can now optionally provide a third argument to ModPagespeedMapProxyDomain in order to use a domains of a separate hosting site for optimized resources being proxied.

- Shared memory named locks are now on by default.
- This reduces file system load when resources are being optimized.
- convert_to_webp_lossless
- Re-compresses GIF and PNG images to lossless WebP.
- ModPagespeedAddOptionsToUrls added
- 3-argument version of ModPagespeedMapProxyDomain added

- Issue 610 Crash with some proxy configurations
- Issue 614 CSS: minify 0.25 -> .25
- Proxying and optimizing resources from trusted domains
- It is now possible to proxy and optimize resources whose origin is a trusted domain but isn’t itself running PageSpeed.
- pagespeed_no_transform attribute for images
- The 'Optimize Images' filter won't optimize an image (though it might still cache extend it) if it has the pagespeed_no_transform attribute.
- convert_jpeg_to_progressive is now a core filter
- The convert_jpeg_to_progressive filter is now enabled by default when ModPagespeedRewriteLevel is CoreFilters.
- Standalone JS Minification
- A command-line JavaScript minifier is now installed when you install PageSpeed. This generates the same minified code as PageSpeed itself.
- Show configuration from /mod_pagespeed_statistics
- The /mod_pagespeed_statistics page (if enabled) now has a Configuration link that shows the filters enabled on the virtual host.
- Better handling of CSS
- The CSS parser now treats sections it doesn't understand as unparseable sections, which are left unoptimized but no longer completely stop the parser. Among other things this allows files containing such sections to be combined per issue 565 as described below.
- insert_dns_prefetch
- Reduce DNS lookup time by pre-resolving at the browser.
- canonicalize_javascript_libraries
- Identifies popular JavaScript libraries that can be replaced with ones hosted by a JavaScript library hosting service.

- Issue 567 [error] "Shutting down PageSpeed child" after binary upgrade
- Issue 568 Cache Flush reported excessively
- Excessive logging when image type is not detected
- Fix Lintian warning when installing deb package
- memcached support
- PageSpeed now includes support for using memcached as an alternative to the file-based cache. Using memcached allows multiple servers to share optimized resources, reducing server load and improving resource utilization.
- SPDY configuration support
- PageSpeed can now be conditionally configured to behave differently when accessed through SPDY.
- CSS3 support
- Parsing of @media tags is now supported, and handling of unsupported @ tags no longer causes parsing to fail.

- flatten_css_imports and fallback_rewrite_css_urls are now enabled in CoreFilters.
- Standalone CSS parser
- In situations where PageSpeed is unable to minify a CSS resource, the new standalone CSS parser can be used to debug why the CSS file could not parsed.
- extend_cache_pdfs
- Extends the cache lifetime of PDFs. This is beneficial when using a CDN, as the CDN can now serve PDFs without having to check the freshness of the content with the origin, while still remaining responsive to PDF updates.
- fallback_rewrite_css_urls
- Enables rewriting of URLs in CSS files if the CSS cannot successfully be parsed. This filter is in the CoreFilters set.
- pedantic
- This filter makes PageSpeed more HTML4 compliant by adding type attributes to style and script tags. This filter is not needed in most cases, as adding those attributes has no effect, but it can be enabled to fix errors reported by HTML validators.
- Enhanced image rewrite filter control
- Finer-grained control for image rewrite optimizations is now provided. Individual filters are now exposed for metadata removal and image conversion.

Mushrooms - P. cubensis
Where: Miami (S. Beach), FL
Time of consumption: Night, 11:15-11:20 PM (24 hrs ago)
How prepared: 5 Fresh mushrooms mixed in blender with 24 oz. of orange juice.
Personal Mushroom experience: 4th experience (3rd this month, Dec.2003).
Timeline would look like this:
-->5 minutes to consume
-->45 minutes light trip/calm before storm/building up fast
-->30 minutes first hard wave of psychedelics/distortions/confusion
-->40 minutes(worst) this is death, or dying in hospital/dejavu-ing
-->50 minutes I'm dead, but not as worried about it/talking better
-->25 minutes don't remember much, dazed, ends in epiphany
This most recent trip was not to be an 'experiment' like the past three. I had been taking baby steps. Small increases after the 1st (1 dried shroom) and 2nd (2 fresh mushrooms) tries, which had very little effect. The 3rd go at it (5 fresh) finally delivered a satisfying sort of 'trip' with lots of giggles and very modest visuals (distorted faces, moving shower curtains, the world viewed at a slightly wider angle).
This 4th time a non-shrooming friend and I drove over the S. Beach with what I thought was the same dose as the previous, mild/ideal trip in a plastic bottle blended with OJ. I chugged my shroothie and Friend and I walked to a bar. I began feeling 'funny' only 5 minutes after consuming my liquid.
First Wave: At about the 45th minute (midnight) I felt like I got slammed by a big psychedelic wave while Friend was getting to just his 2nd beer. I had been looking over at a hot South American mamita. Seemed that every time I'd look back at her she would age 5 years and lose and inch in height. After a short while she had become a 4-foot joan rivers. The jukebox music was becoming unbearably loud, mixing with the bar croud's laughing and shouting, and the cracks of billiard balls, becoming this sort of distorted screech of a demon from hell.
I began to panic a bit about one hour into the experience. Objects, people, the floor, were becoming a bit too distorted. I wanted to go outside, but Friend insisted on finishing his pitcher. Feeling anxious to the 10th power, I decided to go take a look outside, but when I got out there I felt unsafe without Friend. I walked back inside and all of the pool tables had moved, and I was so sure that the bar was on the wrong side of the room. I was officially having a bad time right then. People that I walked past were speaking Klingon. Three times I decided to get off my stool and go to the bathroom where I'd drink water out of the faucet. I would repeatedly pull my phone out of my pocket to check the time, and it would either stay the same time or go backwards. Life would go in slow motion for a minute, and then it would go fast-forward.
Finally outside after Friend had finished his pitcher, I became a bit more at ease. I could not really talk, I could either say 'yep' or 'nope'. Despite it being 73 degrees, I was freezing, walking down Collins Ave. with my hands in my arm pits, like whats-her-name on SNL. I needed silence in the worst way so I asked Friend to take me to the sand. It took FOREVER to walk a block.
Friend: 'You like that girl's *ss?'
Me: (not even looking up from my shoes) 'Yep.'
Friend: 'Cummon, lets go to a bar.'
Me: 'Nope'
Friend: 'Why not?'
Me: 'Can't do it.'
I would try my best to explain to Friend that I was really freaking the bleep out, but he did not totally understand the state I was in. One thing I did enjoy on the walk down Ocean Drive was some of the hotel lights. Stopped and stared at the Colony Hotel for a few seconds, but became uncomfortable for some reason. I felt better just looking down and following Friend as he searched for a place to urinate. When I looked down the street it was all twice as wide as normal. I could hear every song out of every car that was creeping along in traffic. 'Overwhelming' is what I would blurt out a few times. 'Too much, too much.'
We found a bench to sit at that was semi-secluded and semi-quiet, that faced away from the strip's mayhem and into the dark where the beach was.  My trip went to another level, Friend kept repeating himself, same question, same laugh. I was trapped in deja vu for what seemed like 1/2 an hour.
Friend: 'Yer gonna be fine.
Me: 'Nope.'
Friend: 'Yer gonna be fine.
 I swore that friend said 'stay away from the light, don't fall asleep.' So when he said that I thought that I was dying in an emergency room and sort of dreaming the whole ordeal. Then I would go back to thinking I was already dead.
At about 1:00 Friend took me across the street to a cheesey tourist theme burger restaurant thinking that food would help. It had only been 105 minutes of tripping, but it felt like 9 hours. I watched the waiter take our order 4 or 5 times. I kept getting up from the booth and going to the restroom. The 3rd time I went to the restroom I stayed in the disgusting trainspotting-ish stall for a long time and phoned my brother. Friend and I were in the restaurant for about and hour, and according to him I spent most of it in the restroom.
The beeps and voices in the restaurant made me think again that I was in a hospital. Then I'd switch to worrying that I wasn't in a bathroom, but maybe out on the street, just hallucinating the whole bathroom scene. I had a big urge to urinate, but was afraid to, in case I was actually on a busy street in front of the public. Thinking how I would hate to embarass family or people that I know by whipping it out and urinating on a busy sidewalk. After many minutes of contemplation I decided to go to the urinal. I was doing everything like a man is supposed to, but it felt JUST like I was peeing in my jeans. I have never peed in my jeans, but I was sure that's what it felt like.
After Friend payed we started our long journey back to the car. Soon as friend said 'we're going home' the 'horror' of the trip ended, and I entered into more of a daze. I barely remember the long walk back, but I do remember the moment I 'woke up' from the trip, finally realizing that I was still alive. Whoa whoa whoa whoa! Talk about relief. It was almost 2:30 AM by then.
After the trip, it is thinking time. New perspectives are developed on everything. Different attitudes toward Friend, family members, job, life direction.
It has only been one day since I went through this. I cannot explain even the half of what went on, since so much of it was indescribable. I had trouble typing this, my mind is a bit screwy still. Hangover?

Before updating your installation of APP, read the Release Notes of the new release. They contain information on compatibility issues, changes and enhancements, and known restrictions.
The platform operator and technology managers must make sure that the following rules are observed: The OSCM version must be higher or equal to the APP version. The APP version must be equal to the controller version.
Example: If you want to use the VMware service controller included in the V17.3 release, you must upgrade OSCM and APP to V17.3 first.
Preparing the Update
Before you start with the update installation, carry out the following steps:
- Make sure that all provisioning operations are complete. Follow the steps as described in Handling Problems in the Provisioning Process.
- If you are upgrading from V17.0:
In the app-domain application server domain, disable or undeploy the following application:
oscm-app
- If you are upgrading from V17.0:
Check for .glassfishStaleFiles files in the app-domain domain. If there are any, delete them. The files are located in
app-domain/applications/<application name>/.glassfishStaleFiles
For example:
app-domain/applications/oscm-app/.glassfishStaleFiles
- Set the following environment variable for your current session:
DB_INTERPRETER: The absolute path and name of the psql executable of PostgreSQL. The executable is usually located in the bin subdirectory of the PostgreSQL installation directory.
Example:
export DB_INTERPRETER="/opt/PostgreSQL/9.1/bin/psql"
- Create a backup of the key file required for the encryption and decryption of service parameters with data type PWD and custom attributes marked for encryption. By default, the file is named key and located in the following directory:
<GLASSFISH_HOME>/glassfish/domains/app-domain/config
Updating the Database
Proceed with updating the database as follows:
- Check whether the file
postgresql-9.4-1206-jdbc42.jar
is contained in the following directories of the application server:
- lib directory of the app-domain domain
- <GLASSFISH_HOME>/mq/lib/ext
If it is not, copy the file from the <install_pack_dir>/install/lib directory to the location where it is missing.
- Create a backup of the bssapp database using the standard PostgreSQL commands. The database backup must be compatible with PostgreSQL 9.1.12.
- Update the following configuration files so that the settings match your current installation:
- db.properties
- configsettings.properties
- configsettings_controller.properties
Particularly take care of settings which have been introduced or changed with the new release to which you are upgrading.
- Update the schema and configuration settings of the bssapp database by executing the build-db.xml file in <install_pack_dir>/install as follows:
<ANT_HOME>/bin/ant -f build-db.xml updateDatabase
Note:
Make sure that Ant runs in a Java 8 runtime environment when calling the build-db.xml file.
Updating the Application Server
After you have executed the preparation steps:
- If you are upgrading from a release prior to V17.0:
Copy the key file of which you have created a backup copy into the following directory of the extracted installation package:
oscm-app-install-pack\domains\app_domain\installer
Make sure that the key file is named key. The installation script will then copy the key file to its default location in the updated version of the application server:
<GLASSFISH_HOME>/glassfish/domains/app-domain/config
Note: For the update installation, make sure that the default path and name are specified in the configsettings.properties file (APP_KEY_PATH="./key"). The installation script expects this default and does not look up the database.
- Redeploy or deploy oscm-app in the app-domain domain.
- In the JVM Options of the application server:
- Set the following setting to false:
-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false
- Delete the following setting:
-XX:MaxPermSize
- Add the following setting:
XX:MaxMetaspaceSize=512m
- If you are upgrading from a release prior to V17.0:
Export the certificate of the app-domain and import it into the bes-domain application server domain of OSCM.
- Restart the app-domain domain.
Updating the Configuration for SAML_SP Mode
If you are running OSCM and the APP software in SAML_SP mode, and if the IdP metadata of your SSO environment have changed, you need to update your WSIT files accordingly:
- Extract the OSCM-wsit.jar file into a separate directory.
The .jar file is located in
<GLASSFISH_HOME>/domains/app_domain/lib
The OSCM-wsit.jar file contains the following files:
wsit-client.xml
STSService.xml
- Adapt the .xml files as required by your environment.
For details, refer to Configuring APP.
- Recreate the OSCM-wsit.jar file with the modified contents.
- Stop the app-domain domain.
- Copy the adapted OSCM-wsit.jar to the following directory:
<GLASSFISH_HOME>/domains/app_domain/lib
- Restart the app-domain domain.
Note: If, for some reason, you recreate the app-domain domain, you also need to recreate the OSCM-wsit.jar in the <GLASSFISH_HOME>/domains/app_domain/lib directory.

Surefire Sweat is made up of a diverse and multi-generational roster of Toronto-based artists. The music, composed by Juno-nominated drummer, Larry Graves, draws on an amalgam of Funk, Jazz, Brass Band, Blues and Worldy rhythms. Inventive arrangements act as a vehicle for the all-star cast of musicians to engage listeners through improvisational explorations and danceable arrangements. Despite being dominantly instrumental in nature, each of the group's unique pieces is propelled by a narrative: colourful journeys that emote real time metaphors of the human condition.
"Cool compositions, captivating arrangements and powerful horn sections are part of this modern jazz album ...powerful and grooving..." -Wulf Muller, All That Jazz
Sound
In this age of electronic dance music and digital wizardry, Surefire Sweat forges ahead with an old-school music-making approach. Full of memorable melodic hooks and toe-tapping rhythms, listeners are carried along by a revolving door of Toronto finest, sweating it out on drums, percussion, guitars and various horns. Sometimes we even sing.
" ... references to traditional forms while continuously innovating melodically and harmonically around the sparkling and venerable rhythms that inform their eloquent music." - Raul da Gama, Toronto Jazz Report
Background
The band released their first full-length album of original music (with support from The Canada Council for Arts and The Ontario Arts Council) in 2019. The music has been played on radio across the globe. The group is currently active performing at various venues across Canada in support of the new album. Recent highlights include appearances at The TD Toronto Jazz Festival, The Guelph Jazz Festival, Toronto’s Small World Music Festival and Princess Margaret Cancer Centre’s Jazz for the Soul Music Series.
" ... toe-tapping rhythms and powerful melodic lines delivered by a strong horn section, Surefire Sweat is a worthy addition to the world of world beats" - Jazz Journal, UK

Product standards Looking through your home, almost every product is mad under specific standard. For example, electrical adapters, size of beds, size of clothes, desktop, laptop, cell phone, etc. Life with kinds of product standards is much easier than without them. Considering travelling to foreign countries, one thing you have to do before setting out is to check what kinds of electrical adapter is required for the country of destination. The product standards make everything pluggable for its relations. Such as all CD have 80 minutes long which allows all CD player can play the standard CD.
Process standards In IT work, the process standards are critical. For example, without the Internet protocol stack, the world can’t fully connected, people can not enjoy the online multi-media, and a lot of new technology can not developed such as cloud computing, Internet of Things, and Intelligence City, etc. The process standard defines how things are composed.
System Standards I worked as internship in a factory years ago. The experience told me how important the Safe management system is in a factory. As we know, there are kinds of machines and producing materials in a manufacture factory. The running machines and toxic materials are danger to workers. The standard of how to manage these things make the safety learnable for factory workers. Such as 4S standard which defines how to organize things through out a factory. Taking running machine for example, the standard defines how far away to the machine by bright yellow line on the ground.
Well, when we look through a stands, it seams quite simple. However, the standard define may spend around ten years from idea, draft, to publish. Because the final released standard should be highest quality. Take USB Type-C connecter for example, it is finalized in August 2014 and currently used on MacBook, Chromebook Pixel, and ASUS Transformer book. It can be used as both electrical cable and USB connector. However, considering the usage of laptop that most of time the electrical cable should be connected, users have to remove the electrical cable first to make USB storage device connection available. It may make the device looks more beautiful, but add troubles for usage. Also, the standard is quite new, and many old devices may not adapter to this standard. So devices, such as in the bellowing picture, are invented. Quite strange phenomenon.

Currently, our team are developing the web client application for online booking system. Because of HTML standard implementation differential between explorers such as Safari, Chrome, FireFox and IE etc., we have to use third party HTML and CSS tool such as Bootstrap developed by Tweeter to solve this issue. It may because of commercial, market or company strategy, the products which unfollow/break the HTML standard have greatly effect IT industry and have cost huge money and IT engineers’ effort to solve the gape. Good news is that the standard breakers are being driven away.
Also, model driven software development is also facing standardization issues. An unit defined standard on model driven software development could highly promote the broad usage of this software development method.
