This sounds like a networking issue. Is multicasting allowed on your network?

Subject: Tomcat 5.0.27 Clustering and session replication


Dear All,
 I'm facing 2 different problems when I'm trying to configure clustering of 2 tomcat 
servers on 2 different LINUX machines which have identical hardware configuration. 

First case:
On both the machines, I've uncommented the cluster block in the server.xml. On one 
machine, I could successfully see the message that Replication member added whereas 
the other machine is not able to recognize the first one and it is displaying the 
message No members active.

Second case:
When I started the tomcat server on one machine,  it is running properly. But when I 
run the server on the other machine, an error message is getting displayed.
java.net.SocketException:Unable to send mcast message. Resource is not available.

Please help.

Thanks in advance.

Vijaya
