ORACLE WEBLogic 12C Clustering of Admin Server ?

Hi ,

I have setup WebLogic Server 12c on solaris 10 u11, as cluster.

 

 

For cluster of managed servers, it works fine.

 

 

My Question is, can we run Admin Server from two nodes of cluster?

 

 

example:  Node 1, created Admin Server, Cluster (F-End1/F-End2) Managed Servers

F-End1 on node1, and F-End2 on node2.

 

 

Now for some reason, Node1 has some hardware problem, can i run Admin Server from Node2 ?

 

I have followed the setup from this website<>

http://www.oracle-base.com/articles/11g/weblogic-11g-clustered-domains.php

 

Followed Same, Pack/Unpack, Enroll.

 

Now from Node 1, i can run, Node Manager, ./startweblogic.sh   and it takes me to the Admin Server.  

from there i can manage every thing. 

 

Question is, can i run Admin Server form Node2? if yes, how?

    Hi,

     

    1) What are the listening addresses you're using when you have admin server in node1 and node2?

     

    Thanks.

    Node1: 10.0.1.179    Admin Server :7001   F-End-1  7003  B-End1   7020

    Node2: 10.0.1.177                                       F-End-2  7003  B-End2   7020

    Hi,

     

    Change the Admin Listen Address to Node 2 Listen IP Address 10.0.1.177 and Restart the Admin server on Node 2. To Access the Admin server on Node 2, Use 10.0.1.177:7001/console

     

    Backup the current config.xml and setDomainEnv.sh files, before doing any changes.

    To change the admin listen address. Please update the config.xml and setDomainEnv.sh files with new the ip address of the node2, where the old ip address is referring.

     

    Thanks
