Explanation
A specific table version record was not retrieved
from the system page because the header page was not available. This
situation typically happens because of lock contention in a high concurrency
environment.

System action
 SQLCODE -904 is issued, and
processing stops.

Operator response
Notify the system programmer.

System programmer response
Lock contention usually resolves itself.
Resubmit the job. If the problem
persists, you might need to report the problem. For information about identifying and reporting the
problem, see Collecting diagnostic data.
