Hello,

i recently came across a problem with the Info-Zip 2.3 we use within
MKS Korn-Shell under Windows 2000 Server to zip Oracle database files.

Info-Zip breaks down when trying to create single zip archives bigger
that 2 GB of size. It's an restriction of the zipper which i found
out. --> http://groups.google.de/groups?hl=de...et%26rnum%3D21

Do you know any other Freeware zippers (as Info-Zip) that are able to
create bigger single archive files?

Any input is higly appreciated,

aeymann

Hi Aeymann,

Depending on the operating system you must change the characteristic
of file-system, which must support archives bigger 2 GB.

For example in HP-UX:
fsadm -F hfs -o largefiles /dev/vg02/lvol1

Gustavo.

Thanks for your input!

The used OS is Windows 2000 Server, which is capable of handling files bigger than 2 GB of size.

My thoughts so far:

1. Create multiple zip archives of the sources to avoid single archive files that are bigger that 2 GB. Good workaround but no solution, cause i zip on directory level and some directorys are already close to zipped 2 GB.

2. Look for another zipper that can create single archive files bigger than 2GB.

I found out that gzip (http://www.gzip.org) eventually supports single archive files bigger than 2 GB. Unfortunately only in the next release :-(

Does anybody know more?

Any input appreciated,

Hi,

you used the commando to rar ?

Gustavo.

WinRar should be a good option.

Basically it doesn't matter which compression format we use. It can be
.gz or .rar also. The script is used to make intermediate backups of
Oracle database files.

Just checked out the WinRar 3.20 limitation, which tells me that the
size of an rar-archive is limited by 8.589.934.591 GB (which is nearly
unlimited - presuming you use an NTFS or equal modern filesystem). It
also comes with an command line version. Alternatively it can create
spanned archives to span the archive over multiple files. It's
commercial though, but not expensive (round 35 Euro for a single user
license with update support).

So that's it for now - goodbye Info-Zip ;-)

Kind regards,

aeymann

One update on this. Some days ago i checked wzzip which is the command line extension of WinZip and makes WinZip usable while getting embedded in scripts.

It works smooth and creates ZIPs bigger than 2 GB without a problem. You might want to load it down here --> http://www.winzip.com/wzcline.htm.
