Hi
I am new to WAS ND,I need some help from all you experts out there

my topology is
one dmrg with application server second app server on different PC web server on third PC
application is working fine some how i got it running but with little confusion

1-while creating JDBC which option to choose cell,cluster,cluster mem or app server
2-how to make sure your application is clustered
3-my application crash if I stop one cluster member which is on dmrg but dose not crash if I stop any appliserever or cluster mem which is on different node.
4-where actually my ear is? on dmrg or on nodes if I want to update any jsp or servlet where I will update manually and will those file get synch to all ?

I will be highly obliged if you answer my these basic Q

Thank

Hi Shaik,

Find my answers below,

1. If the connection is for the clustered application then use cluster.

2. Create a cluster and install the application to the cluster.

3. I think all the requests are going to one node. Check your http server load balancing.

4. Its there in the DMgr, no need for manual updates, just update the application from admin console.

Thanks,
Mani

Hi Sahik,

To narrow down the issue, check whether the ear is available in the other node's installed apps folder. If its there then bypass the webserver and directly access the application. If you can access the application then the problem is with the plug-in. To me the plug-in
looks ok.

Thanks,
Mani
