Remediation/Fixes
Obtain the latest Java JRE CPU update for the IBM Java SDK by using the following information.
- If you are running ADI V5.0.5, skip this step. For V5.0.4, complete the following substeps.
- Stop the server . Navigate to the server directory in your Rational product installation path and run this script:
server.shutdown - Modify the healthcenter parameter set.
- Navigate to the server directory in your Rational product installation path, open the
server.startupscript by using your preferred text editor (e.g., Notepad for Windows or Vim Editor for Linux). - Search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in the
server.startupscript to find the line that contains the healthcenter parameter.
NOTE: For some Rational Collaborative Lifecycle Management versions, -Dcom.ibm.java.diagnostics.healthcenter.agent parameter may not be found in theserver.startup, in this case the update is not needed and you can start using your server. - Windows:
Comment out the line (where the HEALTHCENTER_OPTS parameter is located) by inserting "rem " at the beginning of the line:
Before modification:
set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
After modification:
rem set HEALTHCENTER_OPTS=-agentlib:healthcenter ... - Linux:
Comment out the line (where the HEALTHCENTER_OPTS parameter is located) by inserting "# " at the beginning of the line:
Before modification:
export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
After modification:
# export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
