Cause. An SDRUPDT process on a remote system was not able to communicate with
the SDR monitor process on the remote system.
Effect. The SDRUPDT process stops. No replication is performed.
Recovery. Start the monitor on the remote system.
452
Cause. SDR could not insert a NSA STOP UPDATE message in the TMF audit trail.
The error code is displayed in the message.
Effect. The RDF updaters will not stop at the proper time to replicate the SQL DDL.
The SQL DDL will not be replicated.
Recovery. Report this error to product support.
453
Cause. SDR was unable to access the specified file. The error code is displayed in the
message.
Effect. The SDR operation that required file access is aborted. If the SDR updater
could not access an RDF configuration then it will not be able to monitor that RDF
configuration. If SDR is unable to access a depot file, SQL DDL replication will fail.
Recovery. Correct the file access problem. SDR should retry the operation after the
error condition has been resolved.
454
Cause. SDR was unable to create a depot, marker, or log file. The error code is
displayed in the message.
Effect. SDR will terminate the operation that required the file. That could cause a
primary SQL DDL operation to fail.
Recovery. Correct the file creation problem.
SDR monitor on the backup system is not running
Unable to send NSA UPDATE message
Unable to access a file
Unable to create a file
