Thanks Arjun, I thought to try this on Monday, but was not able to resist to fix it :-) And happy to say, following this solved the issue, now OAS is running. Thanks again.

Hey Mallikarjuna Kuppauru-Oracle This seems a great solution. specific to the question. I will try this, and update here. Thanks.

Is their any easy step available now for switching database in OAS now ?

Hi @Michal Zima Can you please mention those steps Even seems complex, if something worked, want to review.
