600: Work rolled back 

Explanation:

The user’s transaction was implicitly cancelled and reset by a ROLLBACK statement because

       1.      You failed to carry out any ADABAS operations within a certain period of time (installation parameter LOCK_TIMEOUT) but held locks which other users were waiting for, or because

       2.      the database instance was in a deadlock situation. The database server was in a situation in which two or more users are holding locks and request further locks that are being held by other users. In the simplest case of two users, one user holds one lock at least and requests another lock. But this lock is held by another user who is himself waiting for the lock held by the first user. This situation can only be resolved if one of the users releases the lock already obtained.

User Action:

In some cases, the error message contains a more detailed description of the error.

In both cases, the lock requests must be checked and modified, if necessary. The last transaction must be repeated.
