I use IDS 9.20 hpux 11.00 and i must reorganize data and indexes.
I ve got new disk.
Has anybody experience stripping with rawdevice ?
Because I wonder if instead of spending time searching the good place for data,index, for tables among disk and interface card,
I could use raw device stripped among disk.
Creating 2 or 3 vg,
creating logical volume ( not fs but raw device ) stripped across disk.
Chunk on the logical volume
Dbspace whith chunks of 2Go.
With these, no need to fragment table by round robin, no need to search the better place to put data. A chunk is on multiple disks and interface cards.
It works, but I think you might have better performance using fragmentation over dbspaces.
PDQ works fast, because every dbspace gets a thread!
It can scan in parallel. If you just place your chunks on different disks, no parallel options are used.
