-71: Session terminated by shutdown (work rolled back)
Explanation:
Your transaction was implicitly cancelled and rolled back by an implicit <ROLLBACK statement>. The database session was canceled implicitly because a database shutdown was forced in parallel by the database administration tool. To speed up a later restart, the database tries to reset and not just terminate open transactions within a short period.
User Action:
Repeat the CONNECT statement and the transaction when the serverdb is ready for operation.
