Hello,
We (the company I work for) are using DPL a lot. And we have a lot of remote STARTs too.

We see a lot of CSMI and CSM2 mirroring transactions.

My question is: what is the difference between CSMI and CSM2 ?

The documentation always cite them together (CSMI, CSM2, CSM3 and CSM5) but don't explain the difference.
Do that indicate the depth of the mirroring (CSM2 activated by CSMI, CSM3 activated by CSM2) ?

These would seem to represent different functions of the mirror transaction, since all point to DFHMIRS.

CSMI is Mirror transaction, CSM1 is SYSMSG Model, CSM2 is Scheduler Model, CSM3 is Queue Model and CSM5 is DL/I Model.

See near the bottom of page www.ibm.com/docs/en/cics-ts/5.4?topic=transactions-category-2

Garry.

Oh, wow, thank you.

I have never heard of a Scheduler model, and both CSMI and CSM2 run the Mirror transaction,
It seems the best way to be sure will be to find the CSMx origins and the commands that generated them.
