Viewing database update activities

Sometimes you need to identify the update activity that has occurred against an IMS database.

For example, you might need to diagnose the cause of database lock situations or find the reason why an excessive amount of processing has been performed against the database. Log Analyzer can provide this information.

Example

The following example shows control statements for the collection of information about the activities that occurred for a transaction (HA90810) on January 30, 2007, from 8:10 to 8:15 in the morning:

ANALYZE
   SLDS=(BMC.TEST019.SLDS,R141)
   LRCPDS=RIHJER.LUI.CNTL
FILTER
   SEL = DEST =  HA90810
INTERVAL
   START=2007030/08100000
   STOP=2007030/08150100
REPORTS
   SUMM=ALL
   LSUMM=000001010
   LDET=0000003010
END

The following example shows a portion of an Analysis Summary report that was generated by the control statements from the previous example. The report shows that all of the activity against transaction HA90810 originated from the APPC/OTMA environment.
