The dspmqinst command is used the display the root installation directory of MQ. In this example (on Linux), the root installation directory is /opt/mqm.

/opt/mqm/bin/dspmqinst

InstName:   Installation1
InstDesc:
Identifier: 1
InstPath:   /opt/mqm
Version:    9.1.0.3
Primary:    Yes
State:      Available

With the root installation directory idenfied, the "mqm" users /home/mqm/.bash_profile file can be updated to have the following.

PATH=$PATH:/opt/mqm9/bin
export $PATH

In this way, commands in the "bin" directory can be issued without including <root installation directory/bin. For example, this is how you would issue the command if .bash_profile was not updated.

/opt/mqm/bin/runmqsc MANAGER01

And this is how the command could be issued after .bash_profile has been updated.

runmqsc MANAGER01
