Shell script call from a DB trigger

Has anybody been able to execute a shell script call from a database trigger?

If so what are the steps to execute it? Do we have any specific packages in Oracle?

There is no specific packages available in Oracle 9i to execute any shell script or shell commands. But you can use external procedures like java or C to call the shell script.Please refer the below site for more details.

There is also a new method in Oracle 10G, where you can use the DBMS_SCHEDULER package to run a host executable.
