Hi All,
Working in egate /ICAN for past 6 years. Any documentation on JMSGrid? What is this used for?
In the topics i read so far about JMSGrid, it is supposed to be Loadbalanced/HA JMS queue. If so how does that work?
Any docs on this topic will be greatly apperciated.
Thanks
Ravi
Having had a look at the documentation on JMSGrid I have two questions at this time .... any help/experience/comments would be greatly appreciated ....
1 - it seems as though the use of JMSGrid 'could' reduce the dependency on a SAN regarding JMS data for fault tolerance/availability .... since, each daemon in the JMSGrid has it's own message store and each message store is kept in sync.
So, whilst each message store could be on a SAN if one were available .... if a SAN wasn't in fact available in, say, a two host setup, each host could run a daemon with it's own message store .... thereby providing a level of resilience, for JMS data at least, in the absence of a SAN ....
.... is this understanding correct or total blithering top hat?
2 - maintaining message sequence through a topic .... when using JMSGrid is it still true that end to end any message sequencing requirements can still be met using a topic?
Thanks in advance.
