Hi all,
i am using db2 server in aix environment,
i have 2 instances db2inst1 and db2inst2 and one user ICMADMIN

i already taken .profile of db2inst1 and added to user namely ICMADMIN
now iam accessing db2inst1 databases with ICMADMIN wothout any problem.

now i want to use the same user (ICMADMIN) to access the databases in db2inst2 also

is it possible at a time two access databases of both the instances at a time ??
if possible how?

if i update .profile in ICMADMIN, it will be effective??

You could catalog the databases from db2inst2 in db2inst1.

Better would be to create a client for the user icmadmin.
(as root) db2icrt -s client icmadmin

Afterwards catalog the nodes and databases:

CATALOG LOCAL NODE - IBM DB2 9.7 for Linux, UNIX, and Windows

CATALOG DATABASE command - IBM DB2 9.7 for Linux, UNIX, and Windows

thanku so much nvk for ur useful info...
i wil try practically , if any issue i will let you know.

NEVER copy profiles from users
prepare the env for the user (create user instance as indicated) and catalog db as indicated
