Dear List,
I had some short advances on a script that duplicates a database from a
windows backup file to a linux host, but now i'm running into strange memory
access violation errors when it comes to opening two database sessions one
after another. For simplicity i send a shortened version of my script and an
excerpt of my shell output. I'm using Python version 2.2.1 on SuSE Linux
8.1. The memory access violations also occur under Windows XP. Other OS i
can't tell.
[EMAIL PROTECTED]:~/scripts> ./duplicateDBInstance.py
Opening database session... No such database newDB!
Opening system session... done.
Log in as system user... done.
Creating database instance newDB... done.
Closing system session... done.
[EMAIL PROTECTED]:~/scripts> ./duplicateDBInstance.py
Opening database session... done.
Shut down database newDB... done.
Drop database newDB... done.
Closing database session... done.
Speicherzugriffsfehler
[EMAIL PROTECTED]:~/scripts>
Thanx in advance!
Best regards,
Oliver
