B.1 Orchestrate Server Might Shut Down When Managing Large Numbers of VMs and Resources

The PlateSpin Orchestrate system has been tested to a support level of 1400 VMs and 124 separate VM hosts being managed.

If these support levels are exceeded, the Orchestrate service (novell-zosserver) might shut down with the following log entry recorded in /var/opt/novell/zenworks/zos/server/logs/server.log:

ERROR: Out of Memory
ERROR : You might want to try the -mx flag to increase heap size.

To change the heap size:

  1. From a text editor, open /etc/init.d/novell-zosserver.

  2. Edit the start parameters in the file to increase heap size:

    1. Change the following entry:

      $ZOS_BIN start -d $ZOS_CONFIG > /dev/null

      to

      ZOS_BIN start --jvmargs=-Xmx4g -d $ZOS_CONFIG > /dev/null

    2. Save the file, then restart the server.
