Shannon,
Initially, it was taking forever and we were only extracting about 20
documents a minute. If you do the math, I think that would end up taking
years to get all 7 million documents. But, we have since re-engineered
the extraction process to do it in "platter" sequence that that has sped
up the extraction process considerably. But, you're right, the juke box
is the limiting factor in this.

Are you finding that it's taking a really long time for the optical drive to
simply read those images so that you can convert them?
I've worked on something similar with an optical drive and the slowest part
of the entire process was the mechanical "performance" of the optical drive
itself.
Which made sense as that was the whole point of the customer getting off of
the optical drive in the first place.

Shannon,
The application is an image extraction of documents stored on an optical
juke box attached to the customer System i. They are moving off of the
System i and need to convert all of their documents into PDF files. Each
member in the file represents a scanned document from the juke box.
There
are more than 7 million documents to be extracted.
Thanks for the suggestions so far. Some of them may have applicability,
but I have to be careful about tinkering with the application in the
middle of the conversion project.

generate that many members.
That's a new one on me.

Subject: File w/Large Number of Members
Hello list,
I'm working with an application that has a work file that builds up a
large number of members while the application is running. It takes
several hours to complete. I even bumped into IBM's restriction of no
more than 32,767 members in a physical file with this one.
I'm have a minor issue with deleting the work file when I'm all done.
When the file has 30,000+ members in it, it can take more than an hour
for a DLTF to run. Has anyone ever run across this before? Are there
any tricks out there to speed up the file deletion process?
