We have been trying to set up a weblogic cluster and are through with most of the activities but we are stuck up with a small problem which is incomprehensible by any of us. We would be obliged if you could help us with it.
The list of activities done by us:
1)Installing weblogic under /opt/weblogic on both the sun boxes.
2)Installation of ORACLE CLIENT under /opt
3)Installation of SQL SERVER type 4 drivers within weblogic installation..
4)Setting up of the Weblogic home, Java classpath,Oracle home in the .profile which is present in the /home/weblogic directory after creating weblogic ids on both the boxes which has its home directory specified as /home/weblogic
5)Creation of a seperate filesystem which is similar in structure in both the boxes which contains the classes,lib,src,servers diretories.
6)Making the DNS entries for the cluster and for both the individual servers. Where the weblogic cluster is bound to the Virtual IP of both the boxes and the servers are bound to the individual virtual IPs of the respective boxes.
7)Changes in the Weblogic properties file (cluster level and server level) and the start and the stop scripts.
i)StartUp file : -DWeblogic.cluster.enable=true -Dweblogic.cluster.name=XYZ -Dweblogic.system.bindAddr=(Viirtual IP of the box) ...........
The path for the deployment for the beans have also been specified.
ii) Weblogic properties file:
a)Cluster level prop file: cluster.multicastAddress has been specified as a unique multicast IP on the same LAN segment (one that is not being used by any other application).
Servlets registered pools created
jsp working dir and other details specified
After having made all these changes when we are trying to start the servers individually they are coming up and also joining the cluster.
But when both the servers are being brought up together we are facing a problem wherein the error thrown on one the console of one of the servers is:
The ERROR :
weblogic.common.internal.WLObjectInputStreamBase.readObjectWL(WLObjectInputStreamBase.java:308)
at weblogic.cluster.TMSocket.execute(TMSocket.java:235)
at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:120)
Tue Jul 10 17:45:33 BST 2001:<E> <MulticastSocket> Multicast socket receive error: java.lang.RuntimeException: I/O error opening JAR file from file:/sk/SharekhanHome/CACStg21
tmp_deployments/ejbjar29815.jar
We are unable to figure out why such an error is being generated.
Ill be really obliged if you can help me out with this problem.
Hoping to hear from you soon
Thanks and Regards
