We are currently looking at two Virtualization solutions to run our high volume MQ/WBI environment. Currently our message volume ranges between 12 - 13 million messages. The messages are destined for the mainframe CICS/DB2. We are looking at VMWare and z/vm. I was wondering if anyone has been through this migration? If so which solution did you pick to virtualize?
Thanks. |

If by "WBI" you mean Message Broker, then you should be aware that v6.0 of Message Broker on zLinux has substantially different database support than on plain Linux (running under VMWare).
This may influence your choices. In general, it's a good idea to review system requirements for all your products on zLinux.

| Jeff, yes we are looking at running Broker on zlinux. What do you mean by the database support is different on zlinux? |

I mean that it v6.0 of Message Broker on zLinux will only talk to DB2.
Review the Supported Databases.

Luisfer,
So, you're running MQ servers under VMWare and you're also running MQ on z/vm. Do the Queue managers running on z/vm talk to MQ z/os and CICS? We roughly have about 12,000 MQ clients that talk to our MQ Window's servers now. We were looking to virtualize our server layer onto z/vm. You mentioned that your volume is around 4K NPM. Is that per day? |

Talking with IMS-DB2.
On z/VM my project is connect around 20.000 clients & 20 million of messages a normal day (30 M as top -sorry -my english-) |

| Jeff, Thank you for that information. We will be using DB2 with our Brokers running on z/vm, zlinux. I was wondering if you know of any issues with running high volume MQ transactions through MQ running under VMWare. I'm talking around 12.5 million messages a day. All of them are NPM. |

If you're using DB2 both for your Broker Db and for any application DB access in your flows... then there aren't any technical reasons that I'm aware of why you can't use zLinux.
So that doesn't eliminate zLinux as a platform choice.
I otherwise don't have any comments.

I would go for z/Linux rather then VMWare given the choice.
Although I don't have hands-on experience with z/Linux, the reliability of z is ... far better then any x86 even virtualised.
Additionally if your z/Linux partitions are on the same z "Box" as your z/OS and CICS your channels from z/Linux MQ to z/OS MQ will run through the virtual IO devices of the z "Box" and should give an additional performance boost to your setup...
<hope mode on>
Now if z/Linux MQ could utilise Shared Queues in the coupling facility one day... that would be a dream come true...
<hope mode off>

Michael,
Do you have experience with VMWare? I've read articles from other companies that have implemented VMWare for MQSeries and Message Broker. However, they've only implemented VMWare in their test environments. They won't touch production, especially if they run a high volume of transactions. Have you heard or read anything of that nature? |
