    When using an Oracle data store and the connection string is greater than 246 characters long it will produce this error in the admin console after saving:



    Product defect IDP-2510.   Connection strings up to a 32 bit integer (2,147,483,647) should be possible



    Waiting to be addressed in a future version of IdP.



    1. Decrypt the web.config.

    2. Open the web.config in a text editor, find the Oracle connection string and enter it as desired, then save the file.
