Hi Friends,
Due to a Database server issue DB team has rebuild the Database in a different RHEL server.

Now what I found is I'm not able to access root_menu as DB server it's trying to connect does not exist anymore
& DB is moved to a new server. (DB Server Hostname , DB name , schema name changed at the time of rebuild for ctrlmem)

Is there any way - I can update the new DB detail & point it to correct server name , DB name - so that I can access root_menu again

cd /ctrlm/em
cat sqlnet.log
