One way is define a workflow. Inside the workflow you put

1)an external process that "points to" the shell script and then
2)put the mapping

The external process must have the "COMMAND" parameter set to the name of the shell script. If the script has parameters you must put them in the "PARAMETERS LIST" separated by "?" (for example, ?par1?par2).

The path where OWB executes the external process I think is the ORACLE_HOME of the OWB.

I hope this helps.

If you don't use workflow, you can try with this more complex solution. I tried with 9i and OWB 9.2 and it's working well.

You create an autonomous procedure (within a package or not) :


And use the sys.shell script that you need your dba/unix admin to install first of all, with a call like that.

sys.shell('sh ' || txt_dir_name || '/send_email_marketing.sh ' || txt_dir_name || ' ' || email_addr );

Then you import your procedure into OWB and use it in your mapping with the "pre-mapping" icon (you can set parameters for your proc with constants if you want).

To implement sys.shell, go to metalink and find "Note:168065.1" - "How to call a UNIX shell script from PL/SQL".

Once it's done once, it's not so bad. But I would still recommend the workflow approach also...
