I trying to call shell scripts through DBMS_SCHEDULER of Oracle. My procedure executed successfully and my shell scripts executed perfect in UNIX. However, the job does not run when i look through in SQL. I dont see any errors. Did any one of you use dbms_scheduler package to call shell scripts ? Do i need to add anything in my shell scripts? Please help
