  2. Restart the data source.
  3. Add the data source back to the multi data source.

What is Oracle GridLink?

A GridLink data source uses Fast Connection Failover and responds to Oracle RAC events using ONS. This ensures that the connection pool in the GridLink data source contains valid connections (including reserved connections) without the need to poll and test connections. Figure 4-2 Fast Connection Failover.
