In the Database side the DBA’s are setting a 20 mintues timeout.

In the application on the Form we need to capture the error message ORA-02396 and display the display the message as shown below:
ORA-02396: exceeded maximum idle time, please connect again

How is that possible to capture this error in the application on the Forms.

Any one have any idea.

Can't you use the ON-ERROR trigger?

Sorry, the question is 'How to capture this', this error happens on the database side when the idle time exceeds,

if i try to capture it in the on-error, it will capture this only when a error happens on the forms right ?, or will it fire as soon as the idle time error fires at the database side, the question is how to invoke it in the form level, so that the on-error can check for this error ?

Thanks

I think you should be looking for DBMS_ERROR_TYPE and DBMS_ERROR_CODE.

I think that a couple of the installations at which I have worked have tried to do this. Unfortunately there is this slight problem, the database has KILLED the session, therefore when the form tries to do something there is NO SESSION therefore there are NO MESSAGES. Try the DBMS error bits and pieces but as you have no session, the only message I expect you to receive is that there is 'no session'. You could keep a running store of the time of the last command and if the time of the next command is more that 20 minutes then a 'no session found' message could be interpreted as a time-out.

Right David, thanks for the correction. I seem to recall a similar thread from the past addressing the same issue.

I didn't look for any past threads but I would be VERY happy to hear of a way to handle this problem.

Have you seen Metalink doc 570378.994? Perhaps that's an option (didn't test it though).

I wonder if that Metalink document is for Forms 10g on 10g AS and DB? I know it didn't work for 9iR2 Forms on 9iR2 AS because the stupid AS didn't receive the signal from the 9iR2 DB. We could time out the AS but the DB process wouldn't stop.
