Exp in 11g failed with exp-00056 and ora-00980 synonym translation no longer valid.
I have two Oracle 11g (11.1.0.7) instances on the same windows server. Let's call the first instance as 'A' and the other as 'B'. I imported instance A from 10g A and B from 10g B. I ran UTLRP also after import. Then I try to export a specific schema to test out exp utility in 11g. The exp was successful in instance A but failed in instance B with exp-00056 and ora-00980 error. Both instances have various number of invalid synonyms. if invalid synonyms were the cause of the failure, why would it succeed in instance A? Any idea?
