CICS Start up - IPL

Hi All,

I have very limited knowledge about CICS. Please can you advise the below query.

I have requested our CICS support team to schedule one new CICS region in live with 15 min down time (shut down at 8pm & start up at 8:15pm) automatically. They have come back with this question "Can you please advise what happens to this CICS region when the Mainframe system it resides on is IPL'd"?

Are they asking whether the region has to be COLD/WARM/AUTO started? Or any other?

Sukumar.

If the Mainframe is IPL'd, then the region must be started as COLD. If the MVS Logger Files have been deleted/defined during this IPL, then the region needs to be started as INITIAL. Other than these two start options, START=AUTO will be OK.

Mainframe IPL's (otherwise known as a COLD start) are infrequent at best.

As you using IBM's Startup-Assist program "DNCBSUA" for CICS/TS?

Note: If you're running an older version of CICS (non CICS/TS), then there won't be any MVS Logger Files (CICS/ESA 4.1.0 and less) nor will there be a Startup-Assist program.
