RDF Messages
Effect. The monitor does not send STOP UPDATE to any other updaters. Instead, it
now attempts to send ABORT messages to all RDF processes that can be reached, and
then waits for them to stop. If and when all processes have stopped, the monitor stops
the receiver and itself.
Recovery. Determine if any updater processes have not yet shut down. Manually
terminate those updaters still running, using a TACL command of the following form:
status *, prog $system.rdf.rdfupdo, stop .
842
Cause. You issued a START RDF command, but the monitor detected that RDF has
already processed a TAKEOVER command.
Effect. The START RDF command fails.
Recovery. The backup database is consistent and ready for use as a backup contingency
database. Perform the rest of your installation-specific operations for switching to the
backup node (for example, enabling TMF auditing on the backup database and starting
your applications).
If you performed the takeover operation inadvertently, you will need to issue an
INITIALIZE RDF command and resynchronize the databases.
843
Cause. The receiver has received audit from the extractor that does not match the
version of audit that the receiver expects.
Effect. The receiver abends.
Recovery. This is an internal error. Contact your service provider.
844
Cause. The updater that generated this message has completed Phase 1 of the online
synchronization operation for its volume on the backup system.
Effect. The updater starts Phase 2 of the online synchronization operation.
Recovery. This is an informational message; no recovery is required.
ERROR - START prevented by RDF TAKEOVER
Incorrect version of audit received
Phase one db synch complete
