How to Create MultiDataSource in Weblogic 10.3

Question

Hi ,
I am looking for some sample code (java code not the WLS code) or document which provides enough details to create JDBC Multi DataSource in Weblogic 10.3.
I am able to create the dataSource but not able to do for MDS.
Thanks in Advance

WebLogic Server has a scripting environment called WLST which is provided for this exact purpose.
WLST uses Python (Jython) as a language and can facilitate the creation of WLS resources, such as datasources, multi data sources. It ultimately uses the set of WLS MBeans and the AdministrationServer to perform configuration and management operations.
There's a specific book in the documentation which covers WLST, which I'd recommend reading to get up to speed on this:L

There are some sample scripts in the WLS installation which should give you some idea of how to do what you need -- jdbc_data_source_creation.py for example.
Further, there's also a very nice facility exposed in the WLS console to help you get going. Using the console, you can record a set of actions, which are generated out as a WLST script. This means you can go into the console, start recording, execute the sequence of steps required to construct your multi data source, and have the sequence saved into a script.
You can then use the script as it stands, or edit it to support whatever specific changes you need.
You could then execute the WLST script from whatever installation process you have -- there's documentation existing on how to invoke WLST as an embedded interpreter directly from Java code.
If you want to do it purely from Java using JMX and the WLS MBeans, then take a look at the WLS JMX guide:
