Hello Everyone!!

I am working on an automation and I have a requirement where operation team manually does this work.

manual work operation team does:

1> login to CICS region lets say they use use command L hlcopqt12.
2>They issue Command EFT1 in CICS terminal.
3>They releases one app lets say app name is apgatathah123.

I am looking to automate those above steps, how I can achieve this using batch job or JCL is there any way we can do that a sample job if anyone has would be great and any link to help me here would also appreciated.

Hello,

You could probably use the EXCI interface to achieve this with a batch job.

This requires a CICS server program and a batch program. The EXCI interface can be setup as effectively logged on and can start the EFT1 transaction. There are samples in SDFHSAMP.

I don't know what you mean by "They releases one app lets say app name is apgatathah123." How is this done?

Thanks for response Garry!

I have no clue about EXCI interface if you could help me with the links to study about it.

This requires a CICS server program and a batch program. The EXCI interface can be setup as effectively logged on and can start the EFT1 transaction. There are samples in SDFHSAMP.

Above statement what s SDFHSANP ??

I don't know what you mean by "They releases one app lets say app name is apgatathah123." How is this done?

This is one manual step that operation team does to release the application this is opcp scheduler concept. we can ignore this for now I will figure this out how to do this step.

If you have any sample JCl you can post here.

Hi,

**.SDFHSAMP is a library of samples supplied with CICS by IBM. High level qualifiers are site-dependent.

Information on using the EXCI Interface is available at:
www.ibm.com/docs/en/cics-ts/5.6?topic=interfaces-external-cics-interface

If your site allows, you could issue console modify command using IEFBR14 to start EFT1

//MYCMD JOB MSGCLASS=A,CLASS=
// COMMAND 'F cics-region-name,EFT1
//STEP1 EXEC PGM=IEFBR14

www.ibm.com/docs/en/integration-bus/9.0.0?topic=zos-issuing-commands-console

My site doesn't allow this, so I hadn't mentioned it.

Garry.

You can issue console commands from REXX. See the REXX CONSPROF command to establish the console environment. Once that's established you can Address CONSOLE "your-console-command". You can use GETMSG to see results of the command.

The REXX userid needs access to issue the command. There is no need to logon to the CICS region.

A quick internet search for 'cics rexx api' gave me a number of hits, i.e. www.ibm.com/docs/en/cics-ts/5.5?topic=programs-eyuapi1 . Most articles seems to imply that you need a CICSplex for using the API. But I'm not a CICS person.
