[JBossWS] - Performance issue with WSProvide Ant Task (Windows only)
by pingus
I'm using WSProvide and WSConsume to create a Web Service client library. Using it on a Linux machine performs well. Switching to Windows it's ~ 20 times slower.
After several attempts to solve this, e.g. adjusting the memory parameters, I checked the network traffic having in mind it could by some kind of "timeout" problem while accessing resources. Using Wireshark I've seen several NetBIOS Name queries like this:
NBNS Name query NB JBOSS-4.2.2.GA<00>
NBNS Name query NB LOG4J.JAR;C<00>
NBNS Name query NB MAIL.JAR;C<00>
All of them get the Answer
NBNS Name query response, Requested name does not exist
As a first-try workaround I've deactivated NetBIOS over TCP/IP in the Network settings and it's fast as expected.
But, what is the reason for this? Why NBNS queries for JBOSS-4.2.2.GA?
Is there any better way to solve this, e.g. a Java option to deactivate NetBIOS requests?
Thanks in advance
Pingus

[Clustering/JBoss] - Failover is taking 15 seconds to recognize by other node.
by nobleman1997
Hi,
I am using jboss 4.0.4 version of jboss. I have set up two linux machine and each has jboss AS installed. Both jboss instances are in cluster.I have used apache 2.0 and mod_jk for loadbalancing. I have configured according to jboss 4.0.4 document.Both servers are set up
as node1 and node2 in both loadbalacer.Also i have used stickysession=1 in worker.properties file.
When both servers are up, my application works fine.
Here is the test case.
When i am browsing my application it is on node2. Now i shut it down node2 gracefully. when i try to continue my application within couple of seconds, it gives error like bad request or application doesn't recognized. if i check log on node1, after 15 seconds node 1 says view accepted (it has list of node in cluster which is just one now ). So to me this fail over is not smooth.
shouldn't it work even though node2 is down ? if i try after 15 seconds it works fine.
Same scenario happen when i use stickysession=0.
So my case is like if somebody is buying stuff online and customer is on node2 of cluster and for some reason node2 is down then it should take over instantly (within milliseconds ) so user's experiance would be smooth otherwise user would
have error page.
Could you please let me know what type of configuration should i setup so i can avoid this type of problem?
Thanks
nobleman
