RDF System Management Manual for J-series and H-series RVUs (RDF Update 13)

column for any RDF process, you should examine the messages in the RDF log file or on the
RDF log device to determine what is happening and what corrective action to take.
Except for updaters, asterisks in the Error column continue to appear in every STATUS RDF
display until the error condition has been corrected.
For updaters, the asterisks disappear when the error is corrected and updating is restarted
after execution of any of the following commands:
STOP UPDATE
STOP RDF
STOP TMF
The occurrence of a critical error only might mean that the primary and backup databases are no
longer synchronized with one another. If, for example, the primary CPU of the disk process goes
down, all updater processes affected by that error condition report a file-system error and then
attempt to restart. If the error does not occur again when the affected updater processes restart,
then the databases are probably still synchronized with one another. In that case, the asterisks are
cleared from subsequent STATUS RDF displays.
For more information on critical errors, you can scan the EMS collectors on the primary and backup
systems:
• The EMS collector on the primary system contains log messages for the extractor and monitor
processes.
• The EMS collector on the backup system contains log messages for the receiver, purger, and
all updater processes.
When RDF is not running, the STATUS RDF report indicates why. For example, the report might
indicate that the subsystem has never been started, or that it has crashed. The report also indicates
where processing resumes in the TMF audit trail when RDF is restarted.
When the BREAK key is pressed while the STATUS RDF command is executing with the PERIOD
option (which requests repeated displays at a specified interval), the break takes effect within one
second rather than waiting until the end of the current interval.
Using RDF Status Data to Control TMF Audit Dumping
You can use the STATUS RDF command to determine when the RDF extractor has finished processing
the audit file that TMF wants to dump. The TMF/RDF trail listed for the extractor in the STATUS RDF
display indicates the TMF audit trail file that the RDF extractor is currently processing.
Approximately 30 seconds after the STATUS RDF display shows that the extractor’s sequence value
is greater than the number of the audit trail that TMF wants to dump, it is safe to mount the tape
and let TMF dump the audit trail if one is dumping to tape and not to disk.
Changing Configuration Attributes
After RDF starts, you can change the following configuration attributes online as the need arises:
• The priority at which each RDF process runs
• The EMS log
• INCLUDE – Modify INCLUDE clauses
• EXCLUDE – Modify EXCLUDE clauses
• RETAINCOUNT
• PURGETIME (altering this attribute causes the purger to perform a purge pass immediately)
• UPDATERDELAY
• UPDATEROPEN
