Symptoms

On Oracle Data Integrator (ODI), when a Package runs in a loop connecting multiple times to a database instance, in the event that the database instance crashes...

... the Package does not reconnect automatically after the database instance is restored, and the following error message is received:

ODI-1226: Step <STEP NAME> after 1 attempt(s).
ODI-1228: Task <TASK NAME> fails on the target connection <NAME>.

To demonstrate the problem, consider the ODI Package below:

The "Extract Data" Procedure step above just connects to a target database, and extracts the data.

In the event of a database crash (or shutdown due to maintenance), the connection will not be re-established, and the error above will arise.
