The CTMEVRT utility is used in a process for recovering DSNEVENTs that were not handled during a CMEM outage or Control-O outage.
In general, the recovery process consists of the following stages:
This utility creates a list of extracted DSNEVENTs that occurred during the time of the CMEM/Control-O outage. It accomplishes this by retrieving DSNEVENTs from the SMF records written during the outage and cross-referencing them with the CMEM/Control-O rules list.
Note:
The following JCL sample for running CTMEVRT and recovering CMEM events can be found in the CTM JCL library. It uses the CTMEVRT procedure in the IOA PROC library:
//*
//* CONTROL-M CMEM: RECOVER LOST DSNEVENTS FROM SMF
//*
//* This is the first stage:
//* Read SMF records to retrieve missed CMEM DSNEVENTs
//*
//* This utility creates a list of extracted DSNEVENTs that occurred
//* during the time of the CMEM outage. It accomplishes this by reading
//* the SMF records written during the CMEM outage and
//* cross-referencing them with the CMEM rules list.
//*
//* The next stage is manually reviewing DAEVENTS.
//* The third stage is running CTMEVEX.

A similar JCL sample for running CTOEVRT and recovering Control-O events can be found in the CTO JCL library. It uses the CTOEVRT procedure in the IOA PROC library. CTOEVRT was introduced in Control-O version 9.0.20.100 and can be applied to prior versions through APAR WM10166.
To enable DSNEVENTs extraction from the SMF, the following SMF record types must be collected continuously: 14, 15, 17, 30, 61, 64, 65, and 119 (z/OS Communication Server FTP records subtype 70).
For examples of a recovery scenario, see the Control-M Event Manager (CMEM) chapter in the Control-M for z/OS User Guide or the Overview of the Rule Parameters chapter in the Control-O for z/OS User Guide.
