|ClearQuest Versions| Applying the fix |
+-------------------+---------------------------------------------------------+
|8.0.0.x | 1. You will need to determine the WAS version used by |
|8.0.1.x | your CM server. To do so, navigate to the CM profile|
|9.0.0.x | directory (either the profile you specified when |
|9.0.1.x | installing ClearQuest, or <clearquest-home>/cqweb/ |
| | cqwebprofile), 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. Identify the latest available fix (per the bulletin |
| | listed above) for the version of WAS used for CM |
| | server. |
| | 3. Apply the appropriate WebSphere Application Server |
| | fix directly to your CM server host. No |
| | ClearQuest-specific steps are necessary. |
+-------------------+---------------------------------------------------------+
For 8.0.x, 7.0.x, 7.1.x and earlier releases, IBM recommends upgrading to a
fixed, supported version/release/platform of the product.
Workarounds and Mitigations
