I installed on two servers and user and its group was created on both servers.
Once instance was created
I modified db2node.cfg file with HAname
And created .rhosts file in instance home directory and add + Instance_name
Db2stop and start commands are failing.
if modify the db2node.cfg file with current hostname . Everthing is working fine.
i verified /etc/services/ , /etc/hosts, .rhosts.
I am getting
08/23/2012 14:54:31 0 0 SQL6048N A communication error occurred during START or STOP DATABASE MANAGER processing.
SQL1025N The database manager was not stopped because databases are still active.
