Serviceguard Extension for RAC Version A.11.17 Release Notes
What’s in this Version
Chapter 110
Support for Shared LVM Online Node Addition and
Deletion
Online node addition and deletion enables the addition and deletion of
nodes in a running SGeRAC cluster. Node(s) can be added and/or deleted
through changing the cluster configuration by editing the cluster
configuration file and re-applying the configuration to the already
running cluster. For deleting online node(s), the node(s) needs to be
halted before deleting them from the cluster.
Support for 8192 Oracle Server Processes for Oracle
9i RAC
The maximum number of Oracle server processes cmgmsd can handle is
8192. When there are more than 8192 server processes connected to
cmgmsd, it will start to reject new requests. Oracle foreground server
processes are needed to handle the requests of the DB client connected to
the DB instance.
Serviceguard Extension for RAC does not support
Mixed Clusters
For SGeRAC, the nodes in the cluster must be on the same architecture.
SGeRAC does not support clusters containing mixed architectural nodes,
which consist of HP 9000 and HP Integrity servers, or different
operating system releases.
