Hi,

I have an old HPUX 10.20 server running Informix 7.23
I need to dump the database to get it off that hardware before it dies.
Unfortunately there is insufficient local diskspace to do so.

I have set up a linux box with sufficient disk onto which I can export the database.

Having configured an NFS link between the two, I ran
dbexport -o /remote
However, the HPUX server has NFS v2 which has a 2Gb file size limit.
Some of the tables being unloaded are over 2Gb in size so the dbexport process terminates when it reaches the first one.

Seems bundle PHNE_25234 would upgrade to NFS v3 but I cannot find it.

My only other idea on how to do this, is to compress the dbexport output on the fly before it is saved to the NFS disk, but I cannot figure out the syntax, or even if it's possible.

Does anyone know how I might achieve this?
Or if it might be possible to transfer the data on the fly another way? By ftp maybe?

Thank you for any help you can offer

Can the -t be used to redirect it to write to stdout? Then you can compress or ssh over to another host to lay down the file. I wonder if the -t output is a tar file or something like that. This page says "-s -": The dbexport and dbimport Programs Try pointing it to a named pipe from '/sbin/mknod name p'. This guy seems to have it working: http://newsgroups.derkeiler.com/Arch.../msg00193.html

The utility ontape is more versatile and fast, but not as platform independent: http://informix-zone.com/idswiki/dok...bexport_ontape

This guy talks about onbar and onunload: http://oreilly.com/catalog/unixbr/chapter/ch14.html

This guy uses unload and a named pipe: http://www.iiug.org/forums/ids/index...ames/read/1026

If you have the schema file, you can select * from each table and save the data that way for future insert/import.

There may be some JDBC tools that will help do this, like kettle and xigole jisql.
