Persistent Java Virtual Machine options
Before NetBackup 9.0, any web service Java Virtual Machine (JVM) tuning values (such as memory allocation) are overwritten during NetBackup upgrades. In NetBackup 9.0, Veritas has defined a set of web server JVM tuning options that persist across upgrades. These options are defined as environment variables in an executable shell script that is stored on the local host. The script's contents override the out of the box JVM tuning options. The script only runs when the NetBackup 9.0 or later web service starts. You can configure the options for which you want to override the default values. You can define this script at any time. Once the values are defined, you do not need to redefine them in any future upgrades.
To define the persistent JVM tuning options:
- Create the
wmcConfig
script in the appropriate NetBackup configuration directory:Windows: install_path\Veritas\NetBackup\var\global\wsl\config\wmcConfig.bat
UNIX and Linux: /usr/openv/var/global/wsl/config/wmcConfig.sh
- Edit the script to include the desired variables from the supported variables list. Each value must be on its own line. Supported variables are:
WMC_HEAP WMC_METASPACE WMC_NEW_RATIO WMC_SURVIVOR_RATIO WMC_GC_CONFIG WMC_HEAP_DUMP_CONFIG
Refer to the JVM documentation from Oracle for more information on the variables and their appropriate ranges.
- Restart the web service to apply the configuration changes.
