You might like to consider the following.
Within your database trigger or stored procedure, if your processing detects a condition which means a Unix job should be run, then write a record to another Oracle table ( let's call it "JobControl" ) containing enough information for a separate job to determine what needs doing.
This separate job is run ( at whatever frequency is appropriate ) via a crontab entry and connects to the database to check if anything needs doing. If not, it goes back to sleep. But if a JobControl record is found, then the approprate action is taken.
( the SQL which polls  the JobControl table could spool output to a file which your Unix job could then pick up on ).
Sounds a bit convoluted, but I have used it and it is quite flexible once set up.

Hope this helps, good luck.

Dear Myerpz,

Thanks a lot for your comment. I really appreciate it. I have couple of jobs running the same way. Instead fo Corntab, I have a scheduler called "Appworx" which does the same. My questions is, directly, can I access the shell script!

Thanks any way.

Regards,
Shashi

The best way to access a shell script from PL/SQL is via Oracle External Procedure calls.

Hi whbram,

Thanks a lot for your response. But I dont have to do anything with forms. I need to execute shell straight from Oracle Database.

Thanks any way.

The code resides in a stored database procedure (PL/SQL).
That means that you can run it from the database.
Calling the procedure from Oracle Forms is just one way of invoking it.
You can call this stored procedure from a number of things, a job queue entry, a database trigger or anything that can call a PL/SQL procedure (even SQL Plus).
