Hi,
Migration of EP from Oracle to DB2 has been completed.
Now while accessing few links,we are getting below error:
****************************************************************************

**************************************************************************
We have changed the jdbc driver specification and url from code.
Basically what has been done is,tables are added from backend and on those tables applications are developed .
Prior to migration things were working,post migration when we are trying to access those links from frontend we are getting above error.
Please find attached original code and changed code:
Also please confirm if there is any need to install drivers separately and define driver path in environment variables.
Who should be doing such changes,Basis admin or EP guy?
