If your queue manager is in a queue-sharing group, you can specify the
log range required by either LRSNSTART (optionally with LRSNEND) or RBASTART
(optionally with RBAEND). You cannot mix LRSN and RBA specifications.
If
you need to coordinate the log information from the different queue managers
in the queue-sharing group, you should use LRSN specifications.
If your queue manager is not in a queue-sharing group, you cannot use
LRSN specifications; you must use RBA specifications.
If you are using a BSDS, RBASTART or LRSNSTART must be specified.
CSQ1LOGP starts its processing on the first record containing an LRSN
or RBA value greater than or equal to the value specified on LRSNSTART or
RBASTART.
Normally you are only interested in the most recent additions to the log.
Take care to choose a suitable value for the start of the log range, and
do not use the defaults. Otherwise, you create an enormous amount of data,
most of which is of no interest to you.
