The RCU creation Hangs in the Select components screen

The RCU creation hangs in the Select Components screen much like what is defined in the the Doc ID. 2704719.1

I am creating the RCU from weblogic 11.2.0.3 in my DB which is on 19c.

The issue appears to be the same. It take almost 13 hours for it to move to the next screen. The solution defined is as follows:

1. Check the database version compatibility with the Fusion Middleware Version - It seems to be compatible even though I do get a warning popup [Doc ID 2635436.1]

2. Purge the existing database table entry and create it with correct details - Please advice which database table is referred to here???
