AMQ8594: WebSphere MQ commands are no longer available in /usr/bin.
In order to run MQ commands you must manage your path configuration asdescribed in the WebSphere MQ product documentation.
In particular review thetopic on "Choosing a primary installation".
-bash-4.1$
InfoCenter,Choosing a primary installation:On UNIX and Linux platforms, the first installation onto a system must be manually configured to be the primary installation. Set the primary installation using the setmqinst command.（可以通过setmqinst命令设置主安装目录）
-bash-4.1$ /opt/mqm/bin/dspmqinst
InstName: Installation1
InstDesc:Identifier: 1
InstPath: /opt/mqm
Version: 7.5.0.0
Primary: No
State: Available
[root@rhv6-64b ~]# /opt/mqm/bin/setmqinst -n Installation1 -i
114 of 114 tasks have been completed successfuly.'Installation1' (/opt/mqm) set as the Primary Installation.（设置/opt/mqm为主安装目录）
PATH=$PATH:/opt/mqm/bin
export PATH（将/opt/mqm/bin加入到环境变量PATH中，解决mq命令在命令行报命令找不到的错误，但是并不建议用这种方式添加，因为当退出终端时，改配置就失效，下次进入仍然报错，建议到/etc/profile添加）
