About setting up a campus cluster for disaster recovery for SFCFSHA or SF Oracle RAC
Campus clusters:
Are connected using a high speed cable that guarantees network access between the nodes
Provide local high availability and disaster recovery functionality in a single cluster
Employ shared disk groups mirrored across sites with Veritas Volume Manager (VxVM)
Are supported for Storage Foundation and High Availability (SFHA) Solutions products including Storage Foundation Cluster File System High Availability (SFCFSHA) and Storage Foundation (SF) for Oracle RAC
Note:
Campus clusters are not supported for Storage Foundation for Sybase CE at this time.
The following high-level tasks illustrate the setup steps for a campus cluster in a parallel cluster database environment. The example values are given for SF for Oracle RAC and should be adapted for an SFCFSHA cluster using another database application.
The following high-level tasks illustrate the setup steps for a parallel campus cluster in an SF for Oracle RAC environment.
Table: Tasks for setting up a parallel campus cluster for disaster recovery
Task | Description |
---|---|
Prepare to set up campus cluster configuration | See Preparing to set up a campus cluster in a parallel cluster database environment. |
Configure I/O fencing to prevent data corruption | |
Prepare to install Oracle RAC Clusterware and database binaries | See the Storage Foundation for Oracle RAC Configuration and Upgrade Guide. |
Configure VxVM disk groups for campus cluster | See Configuring VxVM disk groups for a campus cluster in a parallel cluster database environment. |
Install Oracle RAC Clusterware and database binaries | For Oracle RAC, see the Storage Foundation for Oracle RAC Configuration and Upgrade Guide. For SFCFSHA, see your database documentation. |
Configure VCS service groups | See Configuring VCS service groups for a campus cluster for SFCFSHA and SF Oracle RAC. |
The sample SF Oracle RAC configuration illustrates the configuration procedures with a four-node campus cluster with two nodes at each site. Each node is running SF Oracle RAC 9.0.
Table: Sample setup for an SF Oracle RAC campus cluster
Site | Hardware description |
---|---|
Site 1: site1 Cluster name: clus1 | Servers: sys1 and sys2 Shared LUNs: disk01 disk02 disk03 disk04 (used as coordinator disk) disk05 |
Site 2: Site name: site2 Cluster name: clus1 | Servers: sys3 and sys4 Shared LUNs: disk06 disk07 disk08 disk09 (used as coordinator disk) |
Site 3: Site name: site3 Cluster name: clus1 | Shared LUN disk10 (used as coordinator disk) |
Although a Coordination Point (CP) server is not used in the current example, it can also be used instead of a third site for a coordinator disk.
