Command Overview
The asterisks will also disappear for updater processes when updating is restarted
after execution of any of the following commands:
•
STOP UPDATE
•
STOP RDF
•
STOP TMF
Note that although the occurrence of a critical error might mean that the primary and
backup databases are no longer synchronized with one another, that is not always the
case. 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,
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.
If RDFCOM cannot connect to a particular process, RDFCOM displays dots (...) in the
RTD Time, Sequence, and RByte Addr fields and an appropriate File System error
number in the Error field.
Special Messages
If you issue the STATUS RDF command while an RDF TAKEOVER operation is in
progress, RDF displays the current state as “TAKEOVER IN PROGRESS.”
If you issue the STATUS RDF command after an RDF TAKEOVER operation has
completed, RDFCOM displays the following message instead of the usual status
display:
STATUS RDF (\RDF04 -> \RDF06) is NOT running
An RDF TAKEOVER has completed
Safe MAT position is SNO 1, RBA 87876660
MAT position for File Recovery: SNO 1, RBA 87876740
Examples
To display current RDF configuration information and operational statistics once, enter
the following command:
]STATUS RDF
To display that information 10 times, once every minute, enter:
]STATUS RDF, PERIOD 60, COUNT 10
