|9.0.0.x, 9.0.1.x   |    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. Check your    |
|                   |    installed version of IBM WebSphere Application Server|
|                   |    against this bulletin's list of vulnerable versions. |
|                   | 2. Identify the latest available fix (per the bulletin  |
|                   |    listed above) for the version of WAS used for CCRC   |
|                   |    WAN server.                                          |
|                   | 3. Apply the appropriate WebSphere Application Server   |
|                   |    fix directly to your CCRC WAN server host. No        |
|                   |    ClearCase-specific steps are necessary.              |
