Shutdown

Hi,

ThanX in advance

Raj,
when you are in your unix shell ORACLE_SID determines which sid/instance you are connecting to...
once connected to svrmgr you can perform select * from v$database to determine which db you are connected to.

which O/S are you running on??? NT or Unix

set oracle_sid=INSTANCE_NAME on NT

export INSTANCE_NAME on UNIX

or you can connect as:

INTERNAL/MANAGER@DATABASE_NAME

good luck
