Hello,
This is my initial post to this z/VM listserv, so please let me know if this should/could
be addressed somewhere else. Here's the scoop.. we're doing the POC (proof-of-concept)
with z/VM 5.3 and have successfully created a handful of z/Linux SuSE server, and from
watching this list serv for a few weeks, looks like there's others doing the same. We're
running on an lpar on a z/10 and have setup HiperSockets to z/OS lpar for z/OS DB2
connectivity to test WebSphere, etc. We've created WebSphere clusters to two z/Linux
AppServer to use WAS clustering (http, plugin, etc.) for "HA" (i.e. no O/S
HACMP-type clustering). This is all OK, just wanted to give a background of what we're
POC'ing.
So here's the open-ended question(s). We've created a z/Linux guest and installed MQ v6 and have done simple
QMGR testing. Again, this is good. So now everybody wants to know how I can make this MQ server and QMGR
"Highly-Available". I can spell MQ and know a little about admininstering it, but assume very
little. So I contend that the z/10 h/w is reliable, the DASD is raid, the vswitch can have failover OSA's,
so as long as we alert and don't fill up filesystems, we have a decent chance to keep the QMGR available on
the z/Linux server. Because of HACMP for AIX and Windows clustering, everybody wants to know about z/Linux
"HA" at the O/S level. Again, I'm still just learning, but have zSeries, AIX, and now a little
z/Linux experience, but I'd like to get other shop's opinions on the z/Linux "HA" concept at the
O/S level... and more specifically to make an MQ qmgr highly available.
How are z/VM and z/Linux shops making WebSphere MQ QMGR highly available on
z/Linux servers?
Thanks in advance,
Tom Burkholder
There is/was a HA Linux project; google should find it.
When last I looked it didn't mention IBM mainframes of any kind, it's
oriented mainly to Intellish systems.
However, it goes into some detail software available to help with
recovery from unplanned failures (including keeping on going) and should
be good background.
