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

About Cross-Subnet Configurations
As of Serviceguard A.11.18, Serviceguard allows you to configure multiple subnets,
joined by a router, both for the cluster heartbeat and for data, with some nodes using
one subnet and some another.
A cross-subnet configuration allows:
• Automatic package failover from a node on one subnet to a node on another
• A cluster heartbeat that spans subnets.
