Interestingly, this is exactly how one of our 3rd party applications uses Java in the DB. I was wondering why they chose this implementation and was about to do some performance tests.
A thing to watch for: I don‘t think that spooling into a file is properly instrumented, so it will appear as a CPU time in ASH.
Thanks,

Betreff: Re: JVM in the database
I use a java procedure to dump blob files to an actual file. We store some PDF's in the database as blob and at times they need to be dumped to a files. Usually its when they want hundreds at time. We found doing this in a loop with PL/SQL was really slow and slower over time. I found a Java procedure to do this and is is super quick.
We also have another to get file and directory information. It returned back more information that PL/SQL and also was really fast.
