I would quite like to run our WMB v7 brokers on AIX as an MQ service, however I believe it would have the following implications - anyone know of any more, or how to get around these ones?
Since it would run the broker under the mqm userid....
Any files created by the broker (file nodes) would have mqm as the owner.
Might also prevent access to existing files or directories created under the previous broker id.
Any SFTP would come from the mqm id, with SSH key implications.
Inability to configure different brokers with own .profiles pointing to different versions of WMB 7, or different ODBC files, or different environment variables.
-----
All in all it would seem better to run the QM under the broker id(s) rather than the other way around. Are there any issues with this approach?
(we have several brokers, each with their own unique broker id). |

Have you looked into the service startup script calling sudo ?

Not yet.
However the service entry is automatically created when you mark the broker as being an MQ service. It is IBM defined.
I suppose I could modify it, but I do wonder if IBM have thought this feature through enough in real-world terms because on the one hand they generally recommend running MQ under mqm.
On the other hand they generally recommend not running a broker under mqm, but creating a new broker id.
But their "start broker as a MQ service" definition automatically uses the MQ id for the broker. |

may be true for distributed non windows. In windows the broker runs as a service under the service id, regardless of how it is started...

| This is AIX; anyone had experience of running WMB as a MQ service? |

A typical setup would be:
1. Create your startup script for init.d as you would normally.
2. In rc.d directory put two scripts (or links to two scripts) startup, shutdown.
3. In your startup scripts, be sure to sudo into the proper service Id (not mqm) and load the mqsiprofile.
Make good use of the sleep command to allow the system to take it easy on startup and shutdown.

Which oddly enough doesn't run Broker as an MQ service. |

I agree with your comment. I was pointing out a 'typical' setup that some people use in the AIX environment to automatically start and stop Broker gracefully, which I assumed was the raison d'etre of the genesis of his inquiry.
It is quite possible that I assumed incorrectly.

Jeff - you are correct. We already have HA startup scripts that work with broker ids.
I would like to simplify matters as we migrate to new hardware and thought that this might be a "quick win", but it would seem that this is not going to work, unless we run MQ under the broker id for each broker. |
