1. Could we have multiple instances of MQ Server with one MQ Server installation?
2. Could we have multiple instances of MQ Client with one MQ Client installation?
Thanks in advance. |

You can run many queue managers on a single machine that has an installation of MQ Server.
You can run many client applications on a single machine that has an installation of MQ Client.
You can install exactly one copy of MQServer on a single machine.
You can install exactly one copy of MQClient on a single machine.
You can install MQServer and MQClient on the same machine. They go into exactly the same directory.

"...on a single machine" means an instance of an operating system. If you are logical partitioning (LPAR); then you will need to install MQ in each operating system instance.
Hardware horsepower is often a determining factor in how many queue manager instances you create "on a single machine." Mainframes can host dozens or hundreds of queue manager instances. For small midrange servers the documentation suggests one, and possibly a second test queue manager instance. |

Every queue manager has a system management burden and the more you have the more channels you may need to inter-connect them.
Try to keep the number of queue managers fairly low. Make projects share them whenever possible. |

1. Can't we have different MQServer versions or MQClient versions installed on a machine?
You can install exactly one copy of MQServer / MQClient on a single machine.
2. Is it true for each supported platform? |

It's not true on "zed Oh ESS", i.e. z/OS.
Otherwise, you get one version per LPAR/machine. This means "the same version of client AND server".

If your machine can be logically partitioned (LPAR), for example: IBM zSeries (mainframe), iSeries (as400), pSeries (AIX), then you have a unique operating system instance in each LAPR. This means that you can have the same or different operating system versions and MQ versions in each of your LPARs.
Or, viewed the other way around, if you only have a single operating system instance, you can only have one MQ version.
Terms like 'machine' or 'processor' or 'box' are not definitive any longer - if they ever were. |

I did mention LPARs.
It's also true that on z/OS, one can install different versions of MQ in the same LPAR.

Yep. Love mainframes. |

I'd be right there with you if we could replace TSO and ISPF with Eclipse.

Yes, I'm aware that for a while now, one has been able to develop COBOL on Eclipse.
That ain't quite what I said.

"I'd be right there with you if we could replace TSO and ISPF with Eclipse.
"
There's nothing pretty about JCL or green characters on black. On that there is universal agreement. If there's a minus to offset the enormous horsepower and reliability of z, it's this stuff.
The mostly one-time stuff, like creating the JCL to launch an MQ instance, can be done with the ISPF panels or on a GUI pc (notepad) or unix (vi), and exported to the mainframe.
Much of the day-to-day MQ admin stuff can be accomplished with MQ V6 Explorer.
But, you know all this.  |

You can only have 1 version of MQServer on a single machine (in this context machine=LPAR) and 1 version of MQClient on a single machine. Client and server may be installed on the same machine, and need not be the same version as each other.
AFAIK this is true on each supported platform.

I'm running WMQ 5.3.1 and WMQ 6.0 at the same time on a z/OS system.
But then mainframes are proper multi-purpose, multi-user computers. |
