After activating standby database we don’t have enterprice manager.
Because we do not have files on operating system,
and also most important one is we have repository with old server data.
Our repository contain data about old server hostname and ports,
But our new server hostname is different,
So we have to recreate repository, drop sysman, wmsys ..
To drop users and recreate repository below command work
emca -repos recreate
emctl stop dbconsole
emctl start dbconsole
TO create operating system files below command
emca -config dbcontrol db
emctl stop dbconsole
emctl start dbconsole
Thats all,
