How to Uninstall Websphere MQ on Linux (Step by Step Procedure)

Uninstalling Websphere MQ in Linux:

Remove install RPMs

login as root

root@websphere mwinstall]# rpm -ivh IBMJava2-SDK-1.4.2-0.0.i386.rpm to install, so I queried to find out what the software name of the rpm was as you cannot use the rpm filename that you used to install the rpm.

root@websphere mq]# rpm -qa | grep IBM
IBMJava2-SDK-1.4.2-0.0

rpm -e IBMJava2-SDK-1.4.2-0.0

This worked however for the other rpm;s I had to remove the fix-packs first

Remove fix pack rpm’s

Use this command to see which Websphere MQSeries base rpms and fixpacks are installed
root@websphere mq]# rpm -qa | grep MQSeries

I used rpm -ivh IBMJava2-142-ia32-SDK-1.4.2-6.0.i386.rpm to apply fix pack
So I used rpm -e IBMJava2-142-ia32-SDK-1.4.2-6.0

install: rpm -ivh MQSeriesRuntime-U809950-6.0.2-2.i386.rpm
remove: rpm -e MQSeriesRuntime-U809950-6.0.2-2

install: rpm -ivh MQSeriesServer-U809950-6.0.2-2.i386.rpm
remove: rpm -e MQSeriesServer-U809950-6.0.2-2

install: rpm -ivh MQSeriesJava-U809950-6.0.2-2.i386.rpm
remove: rpm -e MQSeriesJava-U809950-6.0.2-2

Remove base rpm’s

I had to do in this order

rpm -e MQSeriesJava-6.0.0-0

rpm -e MQSeriesServer-6.0.0-0

rpm -e MQSeriesRuntime-6.0.0-0

Query to make sure they have all been removed

rpm -qa | grep MQSeries

Remove MQ directories

/opt/mqm # cd /opt , rm -rf mqm
/var/mqm # cd /var , rm -rf mqm
