I have a database link that connects to a databases that is running 11g (11.2.0.4.0).

The database it is created in was recently upgraded to 19c. After the upgrade, I can no longer access remote tables using fully qualified table names.

Prior to upgrade:

 select * from schema.table@link;

and

select * from table@link;

both worked fine.

After the upgrade:

select * from table@link;

works

select * from schema.table@link;
gives the following error:
ORA-02002: error while writing to audit trail
ORA-00942: table or view does not exist
02002. 0000 - "error while writing to audit trail"
*Cause:
*Action:

Has anyone seen this? My DBA assures me that the tablespaces all have plenty of room.

The database that was upgraded is an oracle RDS instance.

Thanks.
