How to Debug an APPX/Oracle Connection 
To see if Oracle is running in a manner that APPX can access it, try the following: 
-  From the Unix prompt, enter the Oracle SQL interface by typing: sqlplus
  -  Enter the UserID and Password that you have coded into your FMS Controls for Oracle.
  -  If Oracle is running, you should get an SQL prompt.
  -  Type: desc {tablename}
 
 
... where {tablename} is the tablename mask defined in your Oracle FMS Controls.
This is frequently: "{DatabaseID}_{ApplID}_{Filename}" 
 all in upper case.
