Hi everyone, a Python and ESRI newbie here.

I wish to use a Python script to register a number of Oracle Materialised View with the geodatabase - please see my sample script below.  How can I instruct the script communicate to the user whether each MView has successfully been registered or not, ideally as a log file, or at least an open text file that the user can manually save at the end if they wish?

Any guidance would be greatly appreciated

Thanks,

Robin

I'm not familiar with Oracle and if you are expecting to capture some output from that, but as to what step in the script it has complete, you can add a "print" or an arcpy.AddMessage after each "RegisterWithGeodatabase" message.  Simplistic, but since you said you are a newbie with python, don't want to overlook it.

...edit:

oh...and opening up the GeoProseccing -> Results tab will show the output messages from your script.

Beyond Rebecca Strauch, GISP​'s suggestion for prints and messages, the general Python methods for opening and writing files (e.g. text files) are found here.

For our scheduled task python scripts, we have it send an email with all the printed debug information, including arcpy.GetMessages(). The script also creates an entry in a scheduled task log table we have in SDE (which is just a fancy way of using a file like Darren mentioned).

This is kind of how we set up our scripts (minus the email part).
