subnets monitored using these individual parameters. While the failure of subnets monitored using SUBNET package configuration parameter is handled by halting the instance of the package on the node where the subnet has failed, the failure of subnets monitored using CLUSTER_INTERCONNECT_SUBNET package configuration parameter is handled by ensuring at least one instance of the package remains running in the cluster.
SGeRAC on HP-UX 11i v3 supports Oracle 10gR2 RAC on ASM over SLVM or raw disks/LUs, CVM/CFS 5.0 with Serviceguard A.11.19.

GMS authorization SGeRAC provides a GMS authorization feature. This feature prevents unauthorized users to access cluster information and register/de-register group memberships. A new parameter GMS_USER[] in the /etc/opt/nmapi/nmutils.conf is used to set this feature. By default this feature is disabled. Support for 8192 Oracle Server Processes for Oracle 9iR2, 10gR2 and 11gR1 RAC The maximum number of Oracle server processes cmgmsd can handle is 8192.
configuration files such as /etc/fstab and /etc/lvmtab will contain references to persistent device files, but Serviceguard’s functioning will not be affected by this. CAUTION: You cannot migrate to the agile addressing scheme during a rolling upgrade if you are using cluster lock disks as a tie-breaker, because that involves changing the cluster configuration. But under certain conditions, you can migrate the cluster lock device file names to the new scheme without bringing the cluster down.
