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
Single Instance Oracle ASM with Separate Disk Groups
Single Instance Oracle ASM with Separate Disk Groups in a Non-Global Zone
This section contains sample configurations of single instance Oracle databases with clustered Oracle ASM instances and clustered Oracle ASM disk groups. There are two diagrams and the second diagram is a continuation of the first diagram.
The following diagram represents clustered Oracle ASM instances that serves two single instance Oracle databases, DB1 and DB2 on Node1. The databases DB1 or DB2 can use either one of the Oracle ASM disk groups DG1 and DG2 or both the disk groups as these are clustered Oracle ASM disk groups. The upper part of the diagram shows the relationships of the Oracle database instances with the clustered Oracle ASM instances on Node1 and Node2. The clustered Oracle ASM instances manage two Oracle ASM disk groups on both nodes at the same time. The lower part of the diagram represents the existing Oracle Solaris Cluster resource group and resources for single instance Oracle databases and their requirement for clustered Oracle ASM services.
The dotted box represents existing HA for Oracle resources with the new Oracle ASM resources. The arrows represent new dependencies between HA for Oracle and clustered Oracle ASM services.
Figure 4 Clustered Oracle ASM with Clustered Disk Groups [1]
In the following diagram, a single instance Oracle database DB2 that shares Oracle ASM disk groups DG1 and DG2 is now running on Node2 after a failover of resource groups DB2-rg to Node2. The upper part of the diagram shows the relationships of the Oracle database instances with the clustered Oracle ASM instances on Node1 and Node2. The clustered Oracle ASM instances manage two Oracle ASM disk groups on both nodes at the same time. The lower part of the diagram represents the existing Oracle Solaris Cluster resource group and resources for single instance Oracle databases and their requirement for clustered Oracle ASM services. If the storage type is hardware RAID, the resource types SUNW.ScaleDeviceGroup, SUNW.rac_svm and SUNW.rac_cvm is not required.
