[JBossMQ] - Re: JBossMQ HA configuration
by venukb
I was hoping very much on the working of selectors in a cluster (In fact I read the same point on the JBM wiki this morning :) )
It was one reason of wanting to have a JBoss MQ in HA (Not sure if the selector behavior is same in MQ as well)
There are some notifications which flow in from a external entity into the enterprise tier and this needs to pushed into the web tier so that its pushed again to the browser (using DWR/cometd).
I was relying on the fact that the web tier could listen based on some selector say (login ID) and we apply that selector on these external notifications so that is picked up by the node where he has logged in.
I was under the assumption that clustered destinations are not bound to any server and expected it to be picked by the right consumer
Guess need to find an alternate way to solve this :)
Also just to be clear, Round Robin and Sucker works only on "Clustered" destinations right ?

[JBossMQ] - Re: Problems changing DefaultDS
by drathnow
Jay,
This whole thing started because of something I read from the WIKI that specifically targeted JBossMQ. After I tried to solve the problem, it looked like it went beyond JBossMQ, hence my post to the JCA forum. Somebody there suggested I post here.
Since you are obviously aware that I posted in JCA, perhaps you might go and actually read the post and the responses I got.
I have not removed my DefaultDS. All I did was change it from HSQL to Oracle as was documented in the WIKI. I did find the file you pointed out and fixed that problem but then something else broke.
I'm not the first person who has run into this. I've found other posts with similar problem but nobody responded.
Thanks for you help,
Dave

[JBossMQ] - Re: Problems changing DefaultDS

This is not an MQ problem. This is a problem in the UUID generator for EJBs.(hence the org.jboss.ejb.plugins....). Please don't cross post issues into forums, until you have gotten an answer from the other. This is not a JCA issue and it's not an MQ issue. It's an EJB issue. Can you please close out your other JCA post, so someone doesn't look up the answer on the other forum.
The problem that you are facing is probably in your server/default/deploy/uuid-key-generator.sar/META-INF/jboss-service.xml file. This file uses a datasource. If you have removed your DefualtDS or you have changed it so it doesn't work, you need to change the line in the file mentioned above to match your datasource.
<depends optional-attribute-name="DataSource">jboss.jca:service=DataSourceBinding,name=DefaultDS

[JBossMQ] - Problems changing DefaultDS
by drathnow
I originally posted this in the JCA forum but it was suggested that I post it here. So, here it is...
JBoss Version is 4.2.0.GA
I searched the Wiki and forums for a solution to this problem. I've seen two other posts with the same problem but nobody responded with a solution to I'll try.
I'm trying to change the DefaultDS datasource from hsql to Oracle. I've followed the instructions I found in the wiki at http://wiki.jboss.org/auth/wiki/ConfigJBossMQDB?action=e&windowstate=norm....
All the JMS tables are being created but the KeyGeneratorFactory fails to deploy. I get the following stack trace in the log:
2008-09-26 08:35:26,847 DEBUG [org.jboss.ejb.plugins.keygenerator.hilo.HiLoKeyGeneratorFactory] Starting jboss:service=KeyGeneratorFactory,type=HiLo

If anyone is interested in the entire stack trace I will post it.
Can anyone tell me what I need to do to get this to fix this?
Thanks,
Dave.
