Dear all,
I'm setting up connection between our SAP PI (7.0 SP25) and a Websphere MQ environment (7.5). We would like to utilize MQ's possibilities for failover without going the HACMP / Power HA way of the underlying AIX OS.
So one possible strategy would be to use multi-instance queue managers on MQ.
However, skimming through this document I'm worried that using multi-instance queue managers would not be feasible because it relies on automatic reconnect that seems not be supported by WebSphere MQ classes for Java? (See Table 1 in below link)
1. Are "WebSphere MQ classes for Java" the one that we have deployed to our PI, or to put it the other way: Are we affected through this restriction on PI then?
---
I've also found this blog that claims that failover with MQ should be possible
However, unfortunatelly this blog seemed not to survive transition from SDN to SCN very well so screenshots that seemed to be essential are missing
2. If going the way, Anandan propoesed in his blog, could anybody give me details on where to put the CCDT file and what content it should have. Did anybody succeed in setting up HA / failover following that blog?
---
And I found this discussion that uses JMS provider settings to set up HA for Apache MQ / ActiveMQ
http://scn.sap.com/message/9859282#9859282
4. Would there be some settings for MQ also to maybe setting up HA that way?
---
4. Is there any other blog or how-to for setting up HA / failover for MQ or do you have any other best practices if the points 1-3 do not apply.
I don't expect to get answers to all 4 points, really any help would be greatly appreciated.
Thanks
Jens
