SF Oracle RAC with Oracle RAC database on I/O domain and guest domain of single host
This section describes the tasks required to set up guest domains on single host for deploying SF Oracle RAC.
Note:
This setup is recommended for use as a four-node cluster by using an additional physical host with the same configuration.
The benefits of this approach are as follows:
Guest logical domains can be added to the host at any time unlike in Scenario 3 where all resources are utilized leaving no room for additional logical domains.
This setup results in better disk performance as compared to Scenario 3.
If the primary domain reboots, only the guest logical domain attached to it is affected. The guest logical domain attached to the secondary service domain continues to be available. Please note that shutting down the primary domain halts all domains.
The disadvantage of this approach is that hardware failures act as a single point of failure, bringing down all associated domains.
Figure: SF Oracle RAC with Oracle RAC database on I/O domain and guest domain of single host illustrates the scenario.
To set up guest domains of single host for deploying SF Oracle RAC
- Complete the preparatory steps for setting up a logical domain environment.
See Preparing to deploy SF Oracle RAC in logical domain environments.
- Create a split PCI configuration on a T2000 Server.
Each bus has 2NICs and 1HBA.
- Create the secondary I/O domain.
- Provision a PCI bus from the primary domain to the secondary I/O domain.
- Create virtual disk service on the primary domain. The virtual disk connected to the service is used by the secondary I/O domain as its root disk.
- Create the disk and network services on the primary service domain and assign it to the guest domain.
- Install Solaris operating system on the secondary service domain and the guest domain using native operating system installation method.
- Install and configure SF Oracle RAC.
Perform the following steps after configuring SF Oracle RAC:
Set the public link to be used as a low priority heartbeat link due to unavailability of NICs.
Run the command "oifcfg" after installation of Oracle Clusterware.
This is required to resolve the issue of different interface names on the guest logical domain and the secondary I/O logical domains.
Configure MultiPrivNic manually.
- Set up Oracle RAC database.
