Hi All,

We have seen many demonstrations of reading a properties file inside a WLST script to make is fully automated and easily managable without Hardcoding anything inside it. We will see many demos of creating and configuring various resources in WebLogic Server using the WLST where we used properties file data as an input to the resource configuration. Here is an example in which we will see How to Configure WebLogic DataSource using WLST?

In this sample we will use a properties file to  avoid hard coding. This script will be same for various DataSource configuration just we need to change the Properties files entry to make a new DataSource.

Step1). Create a Directory somewhere in your file system like:  “C:WLST_DS_Creation” and place a properties file like below in this directory with name “details.properties”

domain.name=7001_Domain
admin.url=t3://localhost:7001
admin.userName=weblogic
admin.password=weblogic

datasource.name=DS_One
datasource.database.name=demo
datasource.target=AdminServer
datasource.filename=DS_One.xml
datasource.jndiname=DS_One_JNDI
datasource.driver.class=com.pointbase.jdbc.jdbcUniversalDriver
datasource.url=jdbc:pointbase:server://localhost:9092/demo
datasource.username=PBPUBLIC
datasource.password=PBPUBLIC

datasource.test.query=SQL SELECT * FROM DUAL

Step2). Now in the same directory write the following WLST Script “createDataSource.py” like following:

from java.io import FileInputStream

propInputStream = FileInputStream("details.properties")
configProps = Properties()
configProps.load(propInputStream)

domainName=configProps.get("domain.name")
adminURL=configProps.get("admin.url")
adminUserName=configProps.get("admin.userName")
adminPassword=configProps.get("admin.password")

dsName=configProps.get("datasource.name")
dsFileName=configProps.get("datasource.filename")
dsDatabaseName=configProps.get("datasource.database.name")
datasourceTarget=configProps.get("datasource.target")
dsJNDIName=configProps.get("datasource.jndiname")
dsDriverName=configProps.get("datasource.driver.class")
dsURL=configProps.get("datasource.url")
dsUserName=configProps.get("datasource.username")
dsPassword=configProps.get("datasource.password")
dsTestQuery=configProps.get("datasource.test.query")

connect(adminUserName, adminPassword, adminURL)
edit()
startEdit()
cd('/')
cmo.createJDBCSystemResource(dsName)
cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName)
cmo.setName(dsName)

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDataSourceParams/' + dsName )
set('JNDINames',jarray.array([String('jdbc/' + dsName )], String))

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDriverParams/' + dsName )
cmo.setUrl(dsURL)
cmo.setDriverName( dsDriverName )
cmo.setPassword(dsPassword)

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCConnectionPoolParams/' + dsName )
cmo.setTestTableName(dsTestQuery)
cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDriverParams/' + dsName + '/Properties/' + dsName )
cmo.createProperty('user')

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDriverParams/' + dsName + '/Properties/' + dsName + '/Properties/user')
cmo.setValue(dsUserName)

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDriverParams/' + dsName + '/Properties/' + dsName )
cmo.createProperty('databaseName')

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDriverParams/' + dsName + '/Properties/' + dsName + '/Properties/databaseName')
cmo.setValue(dsDatabaseName)

cd('/JDBCSystemResources/' + dsName + '/JDBCResource/' + dsName + '/JDBCDataSourceParams/' + dsName )
cmo.setGlobalTransactionsProtocol('OnePhaseCommit')

cd('/SystemResources/' + dsName )
set('Targets',jarray.array([ObjectName('com.bea:Name=' + datasourceTarget + ',Type=Server')], ObjectName))

save()
activate()

Step3). Now Open a Command/Shell Prompt and then run the “setWLSEnv.sh” script to set the CLASSPATH and PATH environment variables. Run the “. ./setWLSEnv.sh” by adding two DOTs separated by a single space …..before the actual script like following : (use ‘cd’ command to move inside the <BEA_HOME>/wlserver_10.3/server/bin) then run the following command….
.  ./setWLSEnv.sh


Note: Here The first DOT represents that set the Environment in the current Shell, AND the second ./ represents execute the script from the current directory.

Step4). Run the Above WLST Script like following:

java weblogic.WLST createDataSource.py

Make sure that the Database is running while you are creating the DataSource.

.
