Installing and Configuring HA for Oracle
A. HA for Oracle Extension Properties
B. Preset Actions for DBMS Errors and Logged Alerts
C. Sample Configurations for Oracle ASM with HA for Oracle
Choosing the Appropriate Oracle ASM Instance
Clustered Oracle ASM with Clustered Disk Groups
Single Instance Oracle ASM with Separate Disk Groups in a Non-Global Zone
This section contains two sample configuration diagrams for single instance Oracle databases with single instance Oracle ASM and single instance Oracle ASM disk groups. The second diagram is a continuation of the first diagram.
Note - Single instance Oracle ASM is not supported with Oracle 11g release 2.
The following diagram represents a single instance Oracle ASM that serves two single instance Oracle databases DB1 and DB2 on a node Node1. The database DB1 exclusively uses an Oracle ASM disk group DG1 and the database DB2 exclusively uses an Oracle ASM disk group DG2. The upper part of the diagram shows the relationships that the Oracle database instances with the single Oracle ASM instances on Node1 and Node2. The single instance Oracle ASM manages two Oracle ASM disk groups DG1 and DG2 on Node1. The lower part of the diagram represents the existing Oracle Solaris Cluster resource group and resources for single instance Oracle databases and their functional requirements for single instance Oracle ASM services.
In the diagram the dotted boxes represent existing HA for Oracle resources with new Oracle ASM services. Inside the nodes, new dependencies between HA for Oracle resources and single instance Oracle ASM services are represented using arrows.
Figure 2 Single Instance Oracle ASM with Separate Disk Groups [1]
The following diagram is a continuation of the previous diagram in this section. In this diagram, the single instance Oracle database DB2 that exclusively uses Oracle ASM disk group DG2 is running on Node2 after a failover of resource group DB2–rg to Node2. The upper part of the diagram shows the relationships of the Oracle database instances with the single Oracle ASM instances on Node1 and Node2. The Oracle ASM disk group DG2 is now served from the single instance Oracle ASM on Node2 while Oracle ASM disk group DG1 is served by the single instance Oracle ASM on Node1.
The lower part of the diagram represents the existing Oracle Solaris Cluster resource groups and resources for single instance Oracle databases and their requirement for single instance Oracle ASM services.
