Datastage Plugins Un-installations Steps

How do I uninstall a plugin in Information Server DataStage for Version 8.xx/9.xx

This blog will explain, How do I uninstall a datastage plugin.  i.e I have to installed the MQSeries Client plugin but I really want the MQSeries server plugin.

Steps to Achieve the same :
1. Make sure everyone is out of the DataStage clients to be sure nothing is locked or the uninstall will fail. ps -ef | grep dsapi_slave to confirm.

2. First you need to figure out what the correct component name is for the uninstall (It is not necessarily the same as the plugin name that you see within DataStage) For 8.0.1 ./dscompinst –v –remove –log /tmp/removeMQ.log MQSeries For 8.5 and 8.7 ./dscompinst -username -password -locale -remove –log /tmp/removeMQ.log mqseries.jar|mqclient.jara. cd into IBM/InformationServer/Server/StagingArea/Installed.b. List out the directory and it will show you all of the components installed.c. The names of the directories listed are what you will use for the component name. For this example, MQSeries is what I want to uninstall

3. Next cd to IBM/InformationServer/Server/DSComponents/bin and run dscompinst:
For 8.1:./dscompinst –username -password –v –remove –log /tmp/removeMQ.log MQSeries

4. This will remove the plugin out of all projects and it will put the plugin components, including its jar file, into a directory called IBM/InformationServer/Server/StagingArea/MothBalled

5. The plugin is now removed.

6. If you want to reinstall a previously uninstalled plugin, you can use the jar file that gets put in the MothBalled directory.

7. This works the same way on windows
