As part of the new requirement, I have to setup a High Available MQ environment to send messages from the z/OS platform to UNIX platform.
z/OS and UNIX platforms have MQ V7.0.1
I am planning to use Multi-Instance queue manager feature which was introduced in 7.0.1. Two UNIX systems will have Active and Standby instance of the queue manager. The IP address of both these UNIX systems will be updated in the sender channel(ie. 'host1(1414),host2(1414)') at the z/OS queue manager.
My query is, whether this kind of setup between z/OS and UNIX will work, and do we need to perform any additional step in case of failover?
I think that it will be automatic fail-over to standby server and we don't need to modify anything at z/OS end to send message to the standby server.
Your thoughts on this please. |

I did that between a MQ z/OS and a MI queue manager on Windows, it works ok (until now  ) This is test system. You need to be sure MQ on z&OS is at level 7.0.1.

ops, right, Thanks!!
I had Win already at 7.0.1 level, and my first try was with MQ z/OS 7.0.0 and it didn't work, I had to install 7.0.1 on z/OS.

Thanks for your reply.....
I think, if it has worked between Win and z/OS, it should also work between z/OS and UNIX.
I was a bit confused because at Information Center, it was mentioned that z/OS does'nt supprt MI as it already have Queue sharing groups for this purpose.
Could you please also let me know what all steps you followed on z/OS to complete this setup.... |

z/OS uses Queue Sharing Groups therefore implementing MI queue managers on that platform in the same manner as other platforms would have been a redundant, and retrograde, step. If you have updated the SDR channel on z/OS there is nothing more you can do other than a 'confidence' check that it works as advertised.

There is a difference between communication with a MI queue manager and actually being one of the MI queue managers.
Sounds like your z/OS just connects to a MI queue manager. All it will need to support is the use of multiple host names in the channel connection string. |
