Post-Logon trigger

• The successful completion of Form Builder default logon processing.
• The successful execution of the On-Logon trigger.

Usage Notes
Use a Post-Logon trigger to provide an event point for a task such as setting up a custom environment
with special variables--to initialize on an application level rather than a form-by-form basis. You might
accomplish this by initializing special global variables from this trigger.
On Failure
Varies based on the following conditions:
• If the trigger fails during the first logon process, Form Builder exits the form, and returns to the
operating system.
• If the trigger fails after a successful logon, Form Builder raises the built-in exception
FORM_TRIGGER_FAILURE .

Example
This example calls a user exit to log the current username and time to an encrypted audit trail file on the
file system, which for security reasons is outside the database.
BEGIN
User_Exit(’LogCrypt ’||
USER||’ ’ ||
TO_CHAR(SYSDATE,’YYYYMMDDHH24MISS’));
END;
