Dear all,
I would like to know how to trigger or submit a JCL in z/OS from z/Linux ?
I do not want to use MQ triggering, as for that I have to create 2 queue managers and to bring it under cluster kind of things.
I know that we can hit via http but that too I am not interested. 
Is there is any other way to achieve my requirement ?
Cheers |

Hi zpat,
Thanks for your reply.
My requirement is a bit different like -
I have a queue manager and queue in windows or z/Linux. On meeting certain trigger conditions it should trigger a z/OS job automatically (Without using Cluster).
If I use ftp as u had mentioned, then I need to give username and password in between, which should be avoided.
If there are some ways to trigger JCL from z/Linux then I just need to trigger that z/Linux app or I can write a script which does that(only in the worst case I will think of writing a script), on reaching trigger condition.
Could you please tell me some ways or open source products that meets my requirement.
Thanks and regards |

I find it highly unlikely that you would be able to cause a job to run on a z/OS box from outside the box without some form of authentication (e.g. user ID and password). So whichever solution you find, you must expect to have to authenticate first.

Hi Hughson,
I agree with you. I am okay with hard coding the credentials or setting up the authentication(ie giving access to one user/machine, just like saving the password, so that it will not ask for password every time) prior to submission of job, in that case it might work, right? as we do in MQ clustering.
So is there any open source products or any other methods to do so ?
I know, via http and MQ we can easily do this but I would like to know more ways.
Thanks and Regards. |

I bet your site security people won't be okay with that.

z/OS doesn't cache credentials like that.

MQ clustering doesn't use credentials.

"Open source" and "z/OS" don't typically occur in the same context.

The z/OS will use CA7 or a similar product to perform it's batch scheduling. It's possible that you can signal CA7 in some way to start the job for you.
But how you'd communicate with CA7 without using http/ftp or MQ I don't know.

IMHO this is impossible. You can't cross the environments like that; even if you have HiperSockets between the z/OS & zLinux it still looks like a TCP/IP connection even though it's a shared memory area in the z hardware. Certainly no zLinux app will have the security context RACF/ACF2 will want for a job to be started.
Think about how you'd achieve this if it was Red Hat Linux not zLinux. The issue is the same.

Connecting non-z/OS systems to z/OS is supported. Transmitting JCL (job-control language) from Windows/UNIX is supported. Transmitting z/OS system commands from Windows/UNIX is supported.
MQ Clusters are not required. Two queue-managers are not required.
Automation software (CA7, Tivoli, as examples) can launch z/OS work when things occur on Windows/UNIX platforms. Do you have automation software?
Transmitting anything between o/s's requires some network support, typically TCP/IP.
I gather that you are not a z/OS person. You will need to talk with your z/OS support folks to get an understanding of what is possible, and how to implement it.

It's entirely possible to connect two queue managers without using a cluster.
It's entirely possible to talk to a zOS queue manager from any other system without using a queue manager on the other system, provided your zOS MQ administrator lets you do it, and has the necessary licenses. |

Hi all,
Thanks for your replies.
I had tried submitting a JCL in MVS from z/Linux via FTP and I successfully submitted it.
This link explains it well.
http://www.ibm.com/developerworks/systems/library/es-batch-zos.html
Now to increase scope, I would like to trigger a CICS transaction from z/Linux or Windows, again without MQ Clustering or http.
Could someone suggest some ways to meet this requirment.
Thanks and Regards. |

Did you try the same technique? What were the results?

Told you you needed HTTP, FTP or MQ

Why will you use FTP but not HTTP? What do you see as the difference?
CICS has the inbuilt ability to accept incoming network traffic (which the batch JCL system lacks) called the CICS Transaction Gateway. It's designed exactly for the use case where a distributed application needs to calls a CICS transaction. Alarmingly (in your instance) it uses TCP/IP not magic invisible non-network connections, but it works very well and there's a raft of documentation and examples surrounding it.

Why do you keep thinking that MQ Clustering is the only way to use MQ?
MQ Clustering is not remotely the same thing as using MQ.
If you mean "Without using MQ at all", then say that. |
