 2 GB limitation, probably asked before
Hi,

I am using a script with ontape to backup our IIF 9.x to a file and I am now
hitting the 2 GB limitation, so I need to make a tapechange in background.
I started to play around a little bit with "expect", but I have problems
plugging the things together. Can somebody help me with that or has a
running scenarion and could provide me with a sample script and expect exp
file?

Any help appreciated.

Thanks
Henri

Hi Henri.

2GB limitation is a each of chunk.

If you use ontape, increase TAPESIZE of onconfig.

HTH.

He is doing the archive to disk - still a 2Gb limit.
Do the archive to RAW disk, then you will not have a 2Gb limit - or just do
it to tape.

Henri,
Search the IIUG software repository using 'ontape' as the query. There's at
least one script I know of (auto_ontape.sh) as an example of what other
folks have done.

No, just remove some of them and let us guess.

You can dbexport to disk over 2GB but then you can't import - it will
make life so much easier:-))

I take there is no truth in the rumour that all the 2GB limitations have
gone in 9.40 - the limit is now 2MB - lots and lots of chunks:-)))

The individual chunk will be able to contain 4TB.

 2 GB limitation, probably asked before
Because that would require significant down time to convert existing data bases.

One of the goals for this is to make it possible for the existing 7.x customer
to be able to migrate to 9.4 so that they can take advantage of the bigger chunk
size and not face a significant down time for the conversion.  We are hoping
that the conversion will not cause the expansion of any internal data structors
and thus will not require significant down time.

The disk IO is 64 bit, so if it was required to fill up a 100 TB disk, you would
be able to define 25 Dhunks of 4TB each with an chunk offset of 4TB increments.
