Undeploy multiple SOA composites with WLST or ANT

As part of our current project the Build Management team asked for a solution to undeploy multiple composites at one time. Of course you have the “Undeploy All From This Partition” menu option in Enterprise Manager but since we have a lot of deployments every day the guys wanted to have a script solution. It is even more important for the nightly deployments on our continuous integration environment – strange, we couldn’t find anybody who wants to do the undeployment via Enterprise Manager manually every night ;-)

However with WLST or ANT the SOA Suite comes with two options to undeploy composites via script. In this article I’d like to explain you both ways.

Undeployment with WLST

You can test the steps below on Oracle's Pre-built Virtual Machine for SOA Suite and BPM Suite 11g.

1) Change to the WLST directory under MIDDLEWARE_HOME/Oracle_SOA1/common/bin.

cd /oracle/fmwhome/Oracle_SOA1/common/bin/

2) Open WLST

./wlst.sh

3)  Connect to the SOA server

wls:/offline> connect('weblogic','welcome1','t3://soabpm-vm:7001')
Connecting to t3://soabpm-vm:7001 with userid weblogic ...
Successfully connected to Admin Server 'AdminServer' that belongs to domain 'dev_bpm'.

wls:/dev_bpm/serverConfig>

4) Run the delete command for the appropriate partition

wls:/dev_bpm/serverConfig> sca_deletePartition('test')

partitionName = test

Partition was successfully deleted.

wls:/dev_bpm/serverConfig>

Please take into account that the command deletes all composites as well as the partition itself. If you need the partition for future deployments just recreate it with the sca_createPartition WLST-command. Also check the Oracle Fusion Middleware WebLogic Scripting Tool Command Reference for a complete list of SOA Suite Custom WLST Commands.

Undeployment with ANT

Another option is to use ANT for the undeployment of multiple composites. The key here is to reference the file ant-sca-mgmt.xml within your custom ANT-target. The file comes with SOA Suite as well as JDeveloper. See my quick example below:

<target name="sca_deletePartition">

  <echo>Undeploy Composites</echo>      

  <ant antfile="/oracle/fmwhome/Oracle_SOA1/bin/ant-sca-mgmt.xml"

     inheritall="false" target="deletePartition">         

      <property name="host" value="soabpm-vm"/>         

      <property name="port" value="7001"/>         

      <property name="user" value="weblogic"/>         

      <property name="password" value="welcome1"/>         

      <property name="partition" value="testPartition"/>      

  </ant>   

</target>

Again this command deletes all composites of the given partition as well as the partition itself. See the Developer's Guide - Managing SOA Composite Applications with Script for more details.
