For optimal performance of the Primary Servers running on VMware ESX, set the reserved memory size to the size of the guest operating system memory. For more information, see TID 7005382 in Novell Support Knowledgebase.
In addition, if the ZENworks 11 SP4 guest operating system supports VMware ESX, enable additional Java commands to set large pages, as follows:
-XX:+UseLargePages
For more information on memory reservation and large memory pages, see Java in Virtual Machines on VMware ESX: Best Practices.
Finally, you need to perform the following tasks:
Create a backup, then open /etc/init.d/novell-zenserver.
In the CATALINA_OPTS string, add the appropriate options, separated by spaces, before the -XX:PermSize option.
CATALINA_OPTS is used to configure the Tomcat container options. For more information on Tomcat, see the Tomcat online documentation.
To start the Novell ZENworks Server services, run the following command:
/etc/init.d/novell-zenserver start
To stop the Novell ZENworks Server services, run the following command:
/etc/init.d/novell-zenserver stop
NOTE:If the Novell ZENworks Server fails to start, there is a compatibility problem with the newly added option, or the syntax is incorrect. To troubleshoot the service startup, run the following command:
/etc/init.d/novell-zenserver debug
The following log file is displayed:
