My way of deployment with WLST

This Script has ultimate goal to automate to one-step process for deploying the code onto WebLogic Development environments. Usually the development environments are going to have multiple time deployments than other environments. Some of the WebLogic environments creates the persistances objects stores into the servers logs path. To avoid previous object references we need to clean up the cache directory that holds this persistance objects. We have developed a python module for clearCache that will do this task automatically.

There could be dependency on application archive files order. Some of the deployments does not requires the shared libraries deployments. Changes in the web application requires Only web app re-deployment. Changes in the enterprise application needs only EAR file deployments. Considering all these dependencies the script is developed in modular structure.

 The following shell script is developed for the environment which I have used to. The domain path you can specify in the DHOME.

#AppDeployment.sh [Optional]
echo '***** WELCOME TO DEPLOYMENT SCRIPT *****'
user=`echo $LOGNAME`
echo 'APPLICATION DEPLOYMENT IS STARTING IN INSTANCE:' $user
DHOME=/Home/domains/wd$LOGNAME/config
WLHOST=`hostname`
cd $DHOME
WLPORT=`cat config.xml |grep listen-port|tr -s [:blank:] |tr " " "\n" |grep listen-port |cut -c14-17`
URL='t3://'$WLHOST':'$WLPORT
DENV=$HOME/domains/wd$LOGNAME/bin/setDomainEnv.sh
. $DENV $*
echo $CLASSPATH
#calling the paniDeployment.py file
java weblogic.WLST -loadProperties /Home/$user/.Admin/deploy.properties /Home/$user/.Admin/paniDeployment.py $user $URL$CLASSPATH 

Now let me give you what I did in my experiment with deployment script, assume that 'a_ejb.jar','a_adapter.jar','b_adapter.jar','c.war' are the deployable archive file components. You may have different components may be target to different WebLogic server instances or clusters it is your choice of targetting.

Well this might be very lengthy you might feel too much!! but bear with me! this is my first time trial which I made ...

On our WebLogic, there are many logics works hahaaaaaaaaaaaaaaaa!! here I am using Python core library modules such as 'os', 'time' etc.
