Notes:CCRC WAN server fixes
Affected Versions
|
Applying the fix
|
9.0.0.x | Apply the appropriate WebSphere Application Server fix directly to your CCRC WAN server host. No ClearCase-specific steps are necessary. |
- Determine the WAS version used by your CCRC WAN server. Navigate to the CCRC profile directory (either the profile you specified when installing ClearCase, or <ccase-home>/common/ccrcprofile), then execute the script: bin/versionInfo.sh (UNIX) or bin\versionInfo.bat (Windows). The output includes a section "IBM WebSphere Application Server". Make note of the version listed in this section.
- Review the following WAS security bulletin:
Security Bulletin: Multiple Vulnerabilities in IBM® Java SDK affect WebSphere Application Server January 2021 CPU
and apply the latest available fix for the version of WAS used for CCRC WAN server.
Note: there may be newer security fixes for WebSphere Application Server. Follow the link below (in the section "Get Notified about Future Security Bulletins") to subscribe to WebSphere product support alerts for additional Java SDK fixes.
