Uncontrolled failover

Before starting an uncontrolled failover, keep a note of the source and target engine's IP address and UUID. These details are available on the Delphix server setup application.

Uncontrolled failover procedure

1. On the source engine, create a replication specification for the dSources and VDBs by clicking Replicate now, to replicate these dSources/VDBs to the target engine.

2. To simulate a crash of the source engine, power off the source engine.

3. On the target engine, click on Failover.

   1. At this point, the target engine will become active and the replicated environments/dSources/VDBs will be seen in the default namespace of the target engine.

The following sections describe the procedures to handle an uncontrolled failover for each data platform:

• Oracle environment and data sources

• SAP ASE environment and data sources

• SQL server environment and data sources
