DR Management

DR Management

The DR management module supports DR service configuration and maintenance, DR monitoring and switchover, and DR tests. This section introduces five DR solutions supported by eReplication in detail.

Prerequisites

During an Oracle database test, planned migration or fault recovery, if the database listeners are not started after the database is started, the database becomes inaccessible. In this case, you must start the database listeners. For details, see Starting Oracle Database Listeners.

Context

Suppose the VM where the production site resides is configured with IP addresses but without NIC. After a DR test, planned migration, or fault recovery, the IP addresses of the VM where the DR site resides are:
  • Windows
    • VM specifications already configured: IP addresses that are dynamically obtained.
    • VM specifications not configured: Consistent with those of the VM where the production site resides.
  • Linux

    IP addresses that are dynamically obtained
