While upgrading from 18.104.22.168 to 13.1.6 the compile invlaid object step of the rpm install failed.
The cause was in invalid package RECLASS_SQL.
The error that was being shown in the compile of RECLASS_SQL was ORA-00980
The reason for the error was a bad synonym obj_rcls_cost_event_rec.
When I looked at the source for the synonym it was pointing at SYS instead of RMS13 schema
I rebuild the Synonym and all was good.
