Configuration procedure

Configuration procedure

  • Follow these steps to set up Oracle RAC disaster recovery with PowerFlex asynchronous replication:

    1. Create PowerFlex volumes to be used as ASM disk groups for Oracle RAC, in both the source and target PowerFlex systems.

    1. Creates two RCGs namely oracle_DATAREDO and oracle_FRA. Set the RPO for both RCGs to 30 s.

    Note: In this configuration, ocrvote and mgmt are not be part of replication. The grid infrastructure software will be running independently in both the source and target systems.

    1. Map the volumes created in both the source and target PowerFlex systems. Essentially, the volumes at the source system must be mapped to the SDCs connected to the source system, and all volumes at the target system to the target system SDCs.
    2. Create 3 VMs in both the source and target cluster and install RHEL 7.6 OS into each VM.
    3. Attach the volumes to each VM. The volume devices will then be visible to each VM.
    4. Configure PowerFlex volumes for ASM and Install Oracle 19c grid and Oracle 19c software in both source and target cluster.
    5. Create ASM disk groups for DATA, REDO, and FRA only on the source. Since the DATA, REDO, and FRA is configured for replication, the ASM header data is also replicated to target volumes.

    1. Verify in target, the OCRVOTE, and MGMT disk group are active and up and running.

    1. Create RAC database on the source.
