Serviceguard Extension for RAC Version A.11.18 Release Notes, 4th Edition, September 2008

NOTE: The cluster node name of a SLVM volume group will be shown in the vgdisplay
command output as the first 30 characters plus a ‘*’ character if the hostname is larger than
31 characters.
• Support for 8192 Oracle Server Processes for Oracle 9i, 10gR2 and 11gR1 RAC
• Support for Oracle 9i RAC, 10gR2 RAC and 11gR1 RAC
• Starting with version A.11.17, all log messages from cmgmsd will log to /var/adm/syslog/
syslog.log by default
• All nodes in the cluster must be either SGeRAC nodes or Serviceguard nodes (SGeRAC
cluster must have SGeRAC software installed on all nodes. SGeRAC version A.11.17 and
later will enforce this homogeneity requirement at cluster creation and formation.)
NOTE: The enhancement in version A.11.17 or later will perform the homogeneity check
to verify the nodes are either all SGeRAC or Serviceguard nodes without any manual
intervention.
For versions prior to A.11.17, there is no homogeneity check during a rolling upgrade to
A.11.17.
• Rolling upgrade is not supported from releases prior to version A.11.15
• SGeRAC does not support a rolling upgrade from Cluster Volume Manager (CVM) version
3.5 to either Cluster Volume Manager (CVM) version 4.1 or 5.0
• SGeRAC does not support a rolling upgrade from Cluster Volume Manager (CVM) version
4.1 to Cluster Volume Manager (CVM) version 5.0
• Serviceguard Extension for RAC does not support Mixed Clusters
All cluster nodes must be either HP 9000 or HP Integrity servers, but not both in the same
cluster
• Fixes
NOTE: Cross-subnet, a new Serviceguard feature introduced in PHSS_37094 on 11i v2 and
PHSS_37095 on 11i v3, is currently not supported with SGeRAC.
