A typical Oracle configuration in a VCS cluster has the following characteristics:
VCS is configured in a two-node cluster.
The Oracle data is installed on shared storage.
The Oracle binaries are installed locally on both nodes or on shared disks.
If you use Oracle ASM feature, then the characteristics are as follows:
The Oracle binaries are installed locally on both the nodes.
The database files are installed on the ASM disk groups.
Review the typical cluster setup illustration for ASM-managed database.
See Figure: Oracle binaries on local disk and Oracle data on shared disk.
The Cluster Server agent for Oracle is installed on both nodes.
For ASM, ASMInst and ASMDG agents are installed on both nodes.
Figure: Oracle binaries and data on shared disks depicts a configuration where Oracle binaries and data are installed completely on shared disks.
Figure: Oracle binaries on local disk and Oracle data on shared disk depicts a configuration where Oracle binaries are installed locally on each node and Oracle data is installed on shared disks.
