1. Re: Farming out a SAR doesnt work
ngais May 21, 2004 6:22 PM (in response to ngais)Hmmm, after doing some more testing in conjunction with the cluster-examples-service that come standard with the jboss configuration, I think the farming service did try to cluster deploy my SAR. However, it seemed to encounter problems (time-out?), and probably just gave up on my SAR without provided any details about the problem.
My test scenarios:
A cluster of two jboss nodes.
The second node was launched after the first node completed its start-up sequence.
The farmed packages were deployed to the first node before I launched it.
The second node always had its farm directory cleaned before launch.
The singleton example was enabled in cluster-examples-service.xml
Test 1:
Only cluster-examples-service.xml was deployed
Result:
Both jboss instances started correctly. In particular, the second node got the singleton example from the first node and deploying it correctly (without invoking the startMethod)
Test 2:
Both the cluster-examples-service.xml and my SAR was copied to first node's farm directory
Result:
The first node started correctly and it deployed both the singleton example and my SAR.
However, when the second node was trying to cluster-deploy what was on the first node, it seemed to got stuck for a short time (probably trying to do something about my SAR). Then, it lost touch with the first node (became suspected) for a while before recovering. The net results were:
- it didnt deploy my SAR
- the singleton went thru some starting and stopping sequences (as a result of the temporary disconnect and subsequent recovery).
See below for the jboss output on the second node:
