Problem(Abstract) |
When upgrading WebSphere® Application Server from v5.0.2
directly to v5.0.2.6, certain JAR files do not get updated properly. This
causes the server load to increase, and if you are using light weight
processes (LWP), this could cause the JVM™ to continuously create new LWP.
On Solaris™ Operating System, you can monitor the LWPs using prstat -p
pid. Use of LWP probably means a steady creation and
destruction of JVM threads. |

|
Cause |
ibmtools.jar, ibmorb.jar and ibmext.jar are not packaged
properly with Cumulative Fix 6, 7 or 8. |
|
|
Resolving the
problem |
There are two solutions to this problem.
- Remove Cumulative Fix 6 and install Cumulative Fix 4. Then, reinstall
Cumulative Fix 6. Cumulative Fix 4 contains the properly-packaged JVM to
avoid this issue. Cumulative Fix 6 does not update the files when
reinstalling because the files show that they have been upgraded.
- Leave Cumulative Fix 6 installed and install the latest Java™ SDK for
the operating system in use.
