In my installation i have some MPP transactions to which they put in messages I.E CHANGE the lterm in the PCB & set the message for another txn
There is another method where they directly do a COBOL CALL
How to find the series of transactions or programs that get invoked
Is there an IMSLOG or some dataset in spool where i can look. I can find all the links from CICS joblog
Pls help

These are called background transactions.
There are a number of datasets that make up the IMS log - the WADS (Write-Ahead Datasets) for immediate write, the OLDS (Online Log Datasets) which has a primary and possibly secondary (in case the primary fails) and finally the SLDS (System Log Datasets) which are the archives. There a number of OLDS and when one fills up, IMS automatically switches to the next available one and schedules a job to copy the full one to one or more SLDS.
There are many, many log records so you should probably start by looking for the type 03 (x'01' in position 1). This is created when data is put into the message queue buffer. |
