HA for Oracle Grid Engine Overview

Oracle Grid Engine is a distributed resource management program, which runs jobs in parallel on multiple machines. To minimize the loss of work that a failure of a machine might cause, nodes in the management tier must be protected against failure. However, protection of individual execution nodes in the grid against failure is not required. Failure of an individual execution node in a grid causes only a minor loss of work.

To eliminate single points of failure in the management tier of an Oracle Grid Engine system, HA for Oracle Grid Engine provides fault monitoring and automatic fault recovery for the following Oracle Grid Engine daemons:

• Queue master daemon

• Scheduling daemon

You must configure HA for Oracle Grid Engine as a failover service.

For conceptual information about failover data services and scalable data services, see Oracle Solaris Cluster Concepts Guide.

Because the management tier relies on the Oracle Grid Engine file system, the NFS server that exports this file system must also be protected against failure. To eliminate single points of failure in the NFS server, use the Oracle Solaris Cluster HA for NFS data service. For more information about this data service, see Oracle Solaris Cluster Data Service for Network File System (NFS) Guide.

Each component of Oracle Grid Engine has a data service that protects the component when the component is configured in Oracle Solaris Cluster. See the following table.
