Adjusting the default heap size for the OpsCenter web server service
The default heap size of the OpsCenter web server service can be increased from 1024 MB to a higher value (like 2048 MB). You can determine a higher value based on the physical memory (RAM) and the virtual memory that is available on your system.
See About adjusting the heap size or cache size for OpsCenter services.
Note:
The information that is published in this section is based on the tests that were performed in Veritas Lab in a controlled environment with expert users. These can only be used as guidelines and should not be used as 100% accurate benchmarks.
Note:
If you start noticing poor performance in the OpsCenter console every few days and restarting the Veritas NetBackup OpsCenter web server service fixes the problem, you should increase the web server service default heap size.
To adjust the default heap size of the web server service on Windows
- Open
OpsCenterGUIService.xmlfile from the following location on the OpsCenter server:Note:
Save a copy of the
OpsCenterGUIService.xmlfile before modifying it. - Modify the Xmx value in the following string:
<EnvVar name="JAVA_OPTS" value="-Xrs -Xms512m -Xmx1024m
For example, replace -Xmx1024m with -Xmx1400m to increase the maximum heap size from 1024 MB to 1400 MB.
Note:
This string may be listed twice in the
OpsCenterGUIService.xmlfile. You can change modify both the occurences of -Xmx in theOpsCenterGUIService.xmlfile to adjust the heap size. - Save the
OpsCenterGUIService.xmlfile. - You must restart all OpsCenter server services for the changes to be effective.
Enter the following commands to first stop and then start all OpsCenter server services as follows: INSTALL_PATH\OpsCenter\server\bin\opsadmin.bat stop
INSTALL_PATH\OpsCenter\server\bin\opsadmin.bat start
To adjust the default heap size on UNIX
- Open the
startGUIfile from the following location:INSTALL_PATH/SYMCOpsCenterGUI/binNote:
Save a copy of the
startGUIfile before modifying it. - Modify the Xmx1024M value in the following string:
JAVA_OPTS="-Xrs -d64 -Xms512M -Xmx1024m...
For example, replace -Xmx1024M with -Xmx1400M to increase the maximum heap size from 1024 MB to 1400 MB.
- Save the
startGUIfile. - You must restart all OpsCenter server processes for the changes to be effective.
Enter the following commands to first stop and then start all OpsCenter server processes as follows: INSTALL_PATH/SYMCOpsCenterServer/bin/opsadmin.sh stop
INSTALL_PATH/SYMCOpsCenterServer/bin/opsadmin.sh start
