Action: Add rollback segment and retry the transaction.
ORA-02092: out of transaction table slots for distributed transaction
Cause: The transaction is assigned to the system rollback segment and is trying to get into the PREPARED state, but the required number of non-PREPARED slots are not available, hence the transaction is rolled back.
Action: Add a rollback segment and retry the transaction.
ORA-02093: TRANSACTIONS_PER_ROLLBACK_SEGMENT(string) more than maximum possible(string)
Cause: Value of parameter specified is greater than allowed on this port.
