Hi MQ Experts,

I like to understand the difference between z/OS versus OS/390 in terms of using WebSphere MQ on the above two oprating systems.

For instance, if a person have good understanding of MQ working on OS/390, how difficult is for the same person to work and use the MQ on z/OS?


Any idea would be highly appreciated


Thank you,

Its pretty much the same OS with a different name. I think after IBM rebranded their line of servers zSeries, xSeries, pSeries and iSeries, they also rebranded some of the os names os OS/390 became z/OS.

Not being a mainframe expert but IMHO it was just a name change. OS/390 springs from MVS anyway.

IBM marketeers went on a naming binge and everything had to be named Websphere <something> or as a <x> Series machine (except MQSeries of course). This was because some of the customers were starting to remember the original names of the products....

Believe it or not, these marketeering sorts are actually paid for what they do - still, it beats working for a living!

Actually the new naming scheme has a meaning behind it
zSeries - z is for zero downtime
xSeries - x is for flexibility
pSeries - p is for performance
iSeries - i is for integration I think.

I really appreciate all of your ideas and it make sense too. Again, it is helped me understanding the difference between OS/390 and z/OS.


Thank you,

yes there is meaning behind the naming.

z - zero downtime is a good one, I thought z was the last in the alphabet so nothing beyond it...
x - comes from the intel x86 architecture
p - can be read as performance or power from the power architecture chip
i - stands for integrated, the old AS/400 had everything in it so is considered the 'integrated' system...

Hope this helped
