The IBM® WebSphere® Application Server installation that is part of CM Server may use a default maximum heap size that must be increased. You can set the JVM heap size from the command line by using a utility provided in the installation.
You first must navigate to the directory in a command prompt to the CM scripts directory (for example, C:\Program Files\IBM\RationalSDLC\common\cm\scripts on Windows®, and /opt/IBM/RationalSDLC/common/CM/scripts on the UNIX® system, and /opt/ibm/RationalSDLC/common/CM/scripts on Linux®). In the following commands, %WAS_BIN% is the path to your eWAS\bin directory (for example, C:\Program Files\IBM\RationalSDLC\common\eWAS\bin).
%WAS_BIN%\wsadmin.bat -profile teamAdminUtils.jacl -c "getJvmMaxHeapSize"The following command (on Windows) sets the maximum heap size to 2048 MB:
%WAS_BIN%\wsadmin.bat -profile teamAdminUtils.jacl -c "setJvmMaxHeapSize 2048"
%WAS_BIN%\wsadmin.bat -profile -profileName cmprofile teamAdminUtils.jacl -c "getJvmMaxHeapSize" %WAS_BIN%\wsadmin.bat -profile -profileName cmprofile teamAdminUtils.jacl -c "setJvmMaxHeapSize 2048"
$WAS_BIN/wsadmin.sh -profile -profileName cmprofile teamAdminUtils.jacl -c "getJvmMaxHeapSize" $WAS_BIN/wsadmin.sh -profile -profileName cmprofile teamAdminUtils.jacl -c "setJvmMaxHeapSize 2048"
The Windows CM Server registry setting that controls the noninteractive heap size on the CM Server for CCRC or ClearQuest® Web server might need to be changed rather than use the default settings. To prevent errors, you can increase the non-interactive desktop heap size. Also, the default registry value for SessionViewSize on Windows must be increased if your system supports larger numbers of CM Server users. For information on increasing the non-interactive desktop heap and SessionViewSize values, see: http://www-01.ibm.com/support/docview.wss?uid=swg21142584
