I believe you are trying to connect LiveCycle with IBM DB2 database server, if yes :
Please go through the install instructions @ http://help.adobe.com/en_US/livecycle/9.0/documentation.html#task=0,1,2,3,4,5,6&module=-1
It has all the details to configure/connect LiveCycle ES2 with IBM DB2 database.
Thanks for ur help Santosh,
I went through the link sent by u.
I have done websphere clustring configurations successfully. But m not able to create Livecycle Database as it requires LC Configuration Manager. It will be great if you can please help with how to do so with configuration manager.
Also, do I need to do anything else apart from 1. creating LC database and 2. websphere clustring configurations.
You need to create DB2 database manually as mentioned in section 4.4 @ http://help.adobe.com/en_US/livecycle/9.0/prepareinstallcluster.pdf
Configuration Manager helps in configuring data source at Websphere cluster/server level.
