Answer 1

The application server is unable to connect to the DB because it does not have the username/password that is stored in the XUSER file. If this is a unix system, then check the home directory for sidadm to see if the .XUSER file (it might be named something like .XUSER.62) is there.
Are you using the sidadm account to start the system?
