Yes you can, using PRECMD command. (%%PRECMD)
You can execute a script sending an email before job execution.
Hi Franck! Long time no see you.
The problem was that %%PRECMD is not suported in Control-M for Oracle Retail Module.
But, it seems my problem is solved.
In Control-M 22.214.171.124 and Control-M for Oracle Retail 8.0, BMC introduced "Run pre-exec" and "Run post-exec" check boxes in General tab for Job definition (Oracle retail jobs).
I will check with Oracle team for testing that functionalities.
