Re: Save File Spanning Mulitple CD's -- MIDRANGE-L

Hey, Bill, although we DO sell a product for premastering CD images (CD-ROM Studio for AS/400), we don't include the ability directly in the product, to break up a single large SAVF. So I don't feel bad discussing this. ;-)

If you have QShell, you can use the 'split' command to break the savf up - copy it first to IFS, either with CPY or CPYTOSTMF. Then the 'cat' command can put it back together. Your install program would need to read each segment to the IFS, then use 'cat' to reassemble. Of course, if this is for a customer, you can't insist, normally, that they have QShell installed.

You could make the SAVF smaller. I like to use gzip/qunzip. It typically compresses a SAVF to 1/7 its original size. These are available (and distributable) from IBM, in the GNU Utilities (find that string in the Search engine - it's part of some "factory" part of developer world or some such).

You COULD save your product into multiple SAVFs - selective saves, then restore each in turn. This is a method we DO include in our product.

The last method involves reading the SAVF record by record, writing each in turn to a physical file, creating a new physical file (or member) as the CD capacity is reached.

To access it again, you need to reconstitute the file - see above. You need to spit out messages, if you use the LODRUN method, asking for the next CD. IBM even has to do this - there CD preparation doesn't automatically span, either.

Is it possible to burn a Save File (that is too large to fit on a single
CD) onto multiple CD's?  Can it be done without any special (translated:
"costly") tools?  And assuming it can be burned, how does one then access
the Save File so its contents can then be restored?

Thanks in advance, Bill
