Restore informix database
I want to make a copy of an existing db on a separate system. The db is backup'd with ontape.
To my opinion the steps you have to take are:
- install informix software
- create db with same devices as on live server
- restore db
Test system contains less disks as production server however totally we have enough space.
The problem is that I have heard that you can't install more than 14 Gb on 1 disk with informix (2 Gb chunks with 7 devices on 1 disk makes 14Gb). Is this correct?
OS: Solaris 7, Informix 7.31.
Heard from SUN that you need to have the volume manager installed if you want more than 7 partitions on 1 disk.
I am surprised that Informix (still) does not support chunks >2GB. Would that also apply to cooked files? Maybe one disadvantage of raw devices vs cooked files.
2 Gbyte chunk limit
there is no difference between cooked and raw.For all versions of informix there is a chunk limit of 2 Gbyte (it's not a limit of disk space however you may define 2047 chunks (2047*2 Gbyte) ).I think starting with Informix 9.3 the chunk size limit will be greater than 2 Gbytes...
If u have less space and though the limit is of 2GB, Till you can restore the
data using filesystem,
i.e create files of size 2GB in mounted file system [Say arount 10GB]
i.e partition at o.s level is for 10GB, but files are of 2GB Size into it..
and use that file to restoration.. Only name should be same as like
A reply ...
after 4 years. Whow.
