the version of Serviceguard Manager appropriate to each.

TIP: To prevent an OutofMemory error reported by Tomcat (Exception in thread
"main" java.lang.OutOfMemoryError: Java heap space), which may occur
especially if the server is under heavy load or Serviceguard Manager is managing a
large cluster (16 nodes with 300 packages), do the following from the command line:
1. Stop hpsmhd
/etc/init.d/hpsmhd -stop
2. Modify /opt/hp/hpsmh/tomcat/bin/startup.sh , adding the following
line in the export statements section:
export CATALINA_OPTS="-Xms512m -Xmx512m"
3. Save the file and restart hpsmhd
/etc/init.d/hpsmhd -start
Current Limitations of Serviceguard Manager
Serviceguard Manager does not yet support the following Serviceguard capabilities,
introduced in the July 2009 patch:
• IPv6–only clusters (see “New Support for IPv6” (page 15)).
If you use cmquerycl -a, or edit the cluster configuration file, to configure an
IPv6–only cluster, Serviceguard Manager's cluster property sheet will display
IPv6 properly. But if you then use Serviceguard Manager to edit the cluster
configuration, Serviceguard Manager automatically changes the configuration to
IPv4–only.
• Online package maintenance (see “Package Maintenance Mode” (page 19)).
You must use the command line, not Serviceguard Manager, to perform online
package maintenance. For instructions, see “Maintaining a Package” in Chapter
7 of the latest version of Managing Serviceguard.
