Notes: * If you use CCRC as an extension offering installed into an Eclipse shell (one not provided as part of a ClearCase release), or you use rcleartool or CMAPI using a Java™ Virtual Machine not supplied by IBM as part of Rational ClearCase, you should update the Java™ Virtual Machine that you use to include a fix for the above issues. Contact the supplier of your Java™ Virtual Machine and/or the supplier of your Eclipse shell.CCRC WAN server fixes

1. 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.
2. Review the following WAS security bulletin:
