Error handling for data pump script

Hi All -

We now have a working script for our data pump job (thanks to some contributions here ).

I have been asked if it would be possible to have some kind of error handling in the script.

Ultimately, there isn't much going on inside the script besides setting a few environment variables and running impdp with a parfile and a log file.

Are there any best practices with data pump for something like this? Could we just do a RETCODE="$?" after the impdp command? Then, a return $RETCODE at the very end?

DB version 12.2.0.1

Regards,

Charles
