Using additional dbspaces makes sense only when you can physically
separate the dbspaces onto separate disks, and thus control the
allocation of disk heads to the database as a whole. If you're using a
single disk, or a RAID or NAS back-end, there is little point to using
dbspaces unless you're running into the maximum size of a file on your
platform (Windows?), which is very large.

Hi all,
Some tables of a production DB (in an enterprise scenario) contain many
milions of rows ...
Is really advisable to create a custom dbspace for everyone of them ?
Does it produce performance improvements ?
Thanks. |
