SGeRAC (formerly known as Serviceguard OPS Edition or
MC/LockManager) is a specialized facility that provides the framework
for using Oracle Real Application Cluster (RAC) software on HP 9000
and HP Integrity servers.
Version A.11.18 of SGeRAC permits a maximum of 16 HP 9000 or HP
Integrity servers configured as a high availability cluster. Multiple
Oracle databases on the same node are supported.

de-coupled from Serviceguard.
NOTE Serviceguard version A.11.18 must now be installed as a prerequisite
product for SGeRAC version A.11.18. The features of Serviceguard
