Agenda
2
• The CLM Patch Service is a new feature included in CLM 5.0
• Part of the Jazz Application Framework (JAF)
– Note: All current and future Jazz based applications “get this for
free”
• The patch service allows administrators to easily:
– Update application servers with patches supplied by IBM support
– Test and verify newly acquired patches
– Rollback patches
– View the list of active patches on a particular system
Overview
3
• Current method for delivering fixes was tedious
– Varied based deployment topology
– Required manual creation of fixes for each APAR
– Patching process was complex and error prone
– Hard to track / identify what fixes were active in a customer environment
• Upgrading to an iFix release required a full installation
– Needed to minimize the amount of code shipped for fixes
– Gives a better “comfort level” for adopters (1MB vs 1GB)
• Developer “Need for Speed”
– Strong need for this in the development and test community
– Initially prototyped to streamline development for continuous delivery
– Example: Apply changes from a developer’s workspace instantly to a deployed test
server
Why did we create the Patch Service?
4
• Automatic Provisioning
• Installing the patch via repotools will provision it after a server
restart
• Reverting the patch via repotools will revert the install back to
the base version on the next restart.
• Cumulative Fixes
• Fixes will now go through full testing like the full release
• Proactive fixes for users
• Smaller install packaging
• Only the changed files are required, not the bundles, so the
resulting install package is much smaller
Patch Service solution
5
• Patches will work on all system configurations, regardless of OS / application server / DB / etc.
• Any plug-in file can be patched, including javascript, html, plugin.xml, manifest.mf, etc.
• Consolidated automated patch build process means that more rigorous functional testing is possible as well as deployment testing
• Predictable releases mean users can plan for the release of patches
• Patches are cumulative – i.e. only one patch is ever active at a time
Unique Features
6
• APAR gets filed
• Development / Support teams determine the fix
• Fix gets delivered to a versioned support stream
• Fix stream builds produce a small zip file (a patch)
New Maintenance Workflow
7
New Maintenance Workflow (cont)
• All fixes for an entire CLM server are handled in a single CLM patch zip file.
• No big download / no new installation necessary.
• The original installation files remain unchanged.
– This makes testing and applying the latest fixes much quicker than before and it is
the future of delivering and consuming fixes!

• PMR reported
• APAR generated
• Patch zip created
• Repotools cmd to apply patch
Using the Patch Service
9
• The patch service introduces the following new repotools commands*:
– repotools.bat -patchApplyGlobal
– repotools.bat -patchRevertGlobal (only used to rollback a patch)
– Applying a patch for side-by-side installs
• If applications are installed together, running a single apply patch
command will patch all applications on the server
• i.e. repotools-jts –patchApplyGlobal
– Applying a patch for distributed installs
• If applications are distributed on multiple servers, the apply patch
command must be run on each distributed application
• i.e. repotools-jts –patchApplyGlobal, repotools-rm –patchApplyGlobal,
repotools-ccm –patchApplyGlobal, etc
* - there are other commands which are not to be used unless IBM
Support instructs you to do so: -patchApplyApp, -patchRevertApp
Repotools commands
10
• The -patchRevertGlobal command is used remove the patch. The maintenance
workflow will require that the existing applied patch will have to be removed
before applied another patch.
• Need to revert before applying next Interim Fix
Repotools commands –patchApplyGlobal and –patchRevertGlobal
11
• The “patch” folder is the monitored location where patches will be
loaded into the OSGi framework.
• Patches should be applied through the repotools commands to prevent
invalid patches from getting applied to servers.
View from the file system
12
View Installed Patches
• Go to JTS Admin page
• Patches, if any, will be listed under Build Information section
13
• Patches only apply to provisioned OSGi bundles within CLM
server applications
• Patches can not:
– update the JVM
– update the application WAR files
– make changes to files outside bundles (such as teamserver.properties)
– be used if a fix requires database schema changes
– be applied to rich-clients (such as RTC Eclipse client, VS, Windows shell,
msscci, CC/CQ connectors, etc.)
– update native components such as RM Browser Add-ons, QM MS
Word/Excel Importer, RCL native library
• NOTE: The maintenance build process will generate a readme file that will
report any parts of a patch that require additional action. Any limitations will be
addressed in the readme text and manual steps will be provided to apply the fix.

• CLM Patch Service is new feature of CLM 5.0 which allows
IBM Support to deliver and maintain fixes to CLM
applications “more efficiently”
• New repotools commands allow for patch delivery and
rollback
• Applied patches are visible from JTS Admin page
• Patches include only the changed files not the entire OSGI
bundle
