Hello,

Currently in the process of upgrading from 7.13 to 9.40 on a brand new server. Two immediate questions spring to mind.

1) Previously we have been restricted to using 2GB chunks. Is there any advantage to using larger chunks. I would presume that copying the db from server to server would be infinately easier if we retain our current db map with 2 GB chunks.

2) Regarding disks for performance purposes is it better to use several small disks to spread the load or can you use larger disks without impacting upon performance.

Cheers
Neal

Hi,

Please, if the time permits it, the best to be to do dbexport, initialize the ON-Line and then run dbimport.
Now, this is imposible and you go from 7.31 to 9.4, i suggest you re create all index and run update statistics.
If this in 7.13, i suggest it that it do dbexport, it reinstall Infomix and then dbimport.
If you have chunk < 2GB, please only run "onmode -BC 1". Not 2.

Gustavo.
