Decompressing a compressed backup image

P: n/a
Hi All,
I have taken an db2 v8.1 fp15 backup on AIX and want to restore it
into a db2 v8.1 fp15 Solaris Box. If the backup was uncompressed, the
cross-platform restore works without any issue. But for compressed
backup images, since the decompression requires compression libraries,
which I assume, is in native AIX binary code(and embedded into the
image), it fails to restore the database.

Could someone advise, if we can decompress the backup image
**outside** the restore process? Can we run the image through a gunzip/
or any other external decompression tool to extract a uncompressed
Backup image?

Thanks in Advance.

This is /exactly/ the reason why I use an external compression utility
(gzip in my case). You might get better ratios w/ the database-based
compression, but you couple yourself to /that/ implementation..

Sorry, I don't have a better answer for you. Can you take the backup
again, w/o compression?
