Hi,

Can some one help me how I can Deinstall db2 on Linux server.
I have db2 express C V9.7 version.
I tried to drop the instance as a root user, but the I got "command not found"
Is this possible if I can Deinstall db2 without dropping instance?

Thanks.

if you want to drop the instance, the db2idrop command is found under a directory named instance in the installation directory. root user generally does not have the current directory(.) in the PATH - so you may have to use ./db2idrop if you are already in the 'instance' directory.
uninstall documentation here - IBM DB2 9.7 for Linux, UNIX and Windows Information Center

Technically speaking, you do not have to drop the instance before uninstall.
