Single Instance ASM with Separate Disk Groups in a Non-Global Zone

This section provides information on the dependency requirements for single instance ASM with single instance Oracle databases and single instance ASM disk groups in non-global zones. There are two diagrams, where the second diagram is a continuation of the first diagram.

The following diagram represents a single instance ASM that serves two single instance Oracle databases DB1 and DB2 running within a non-global zone ZoneA on Node1. The database DB1 exclusively uses ASM disk group DG1 and database DB2 exclusively uses ASM disk group DG2.

The upper part of the diagram shows the relationships of the Oracle database instances with the clustered ASM instances on Node1 and Node2. The single instance ASM manages two disk groups DG1 and DG2 on Node1. The lower part of the diagram represents the existing Sun Cluster resource groups and resources to independently failover DB1, DG1 or DB2, DG2 to ZoneA on Node2.

In the diagram the dotted boxes represent existing Sun Cluster HA for Oracle resources with new ASM resources. Inside the nodes, new dependencies between Sun Cluster HA for Oracle resources and single instance ASM resources are represented using arrows.

The following diagram is a continuation of the previous diagram. In this diagram, the single instance Oracle database DB2 that exclusively uses ASM disk group DG2 is running on Node2 after a failover of resource group DB2–rg to Node2. The upper part of the diagram within the non-global zone shows the relationships of the Oracle database instances with the single instance ASM instances on Node1 and Node2. The ASM disk group DG2 is now served from the single instance ASM in ZoneA on Node2 while ASM disk group DG1 is served by the single instance ASM in ZoneA on Node1.

The lower part of the diagram represents the existing Sun Cluster resource groups and resources to independently failover DB1, DG1 or DB2, DG2 to ZoneA on Node2.
