How to change the eis connection during runtime

It is possible to change the eis connection name during runtime using the following approach.

1. Use assign activity and declare the eis connection details as xml fragment and point it to target partnerlink on the right side in assign activity window.

EndpointReference xmlns="http://schemas.xmlsoap.org/ws/2005/04/addressing"
Address eis/DB/XXX_SQLDB /Address
EndpointReference

This will update the partner link with new value. There after the db operations performed will be on new database.
