Introduction to Serviceguard Extension for RAC
Serviceguard Extension for RAC Architecture
Chapter 120
Serviceguard Extension for RAC Architecture
This chapter discusses the main software components used by
Serviceguard Extension for RAC in some detail. The components are:
• Oracle Components
— Custom Oracle Applications
• Serviceguard Extension for RAC Components
— Group Membership Services (RAC)
— Package Manager
—Cluster Manager
— Network Manager
•Operating System
— Volume Manager Software
—HP-UX Kernel
Group Membership Daemon
In addition to the Serviceguard daemon processes mentioned in Chapter
3 of Managing Serviceguard, there is another daemon that is used for
each version of Oracle to enable communication with Serviceguard
Extension for RAC:
• cmgmsd—Group Membership Daemon for RAC (OPS) 8.1 or later
releases
This HP daemon provides group membership services for Oracle Real
Application Cluster 8.1.x. Group membership allows multiple Oracle
instances to run on the same cluster node. GMS is illustrated in
Figure 1-2 on page 18.
