Hello:
I am reading latest MaxDB online docs, and found this:
1) USE_OPEN_DIRECT
Q: do you recommend this on a Linux w/kernel 2.6? which Filesystems
make sense for this parameter?
2) "Only for UNIX/Linux: do not use hard disks with a journal file
system for the volumes. Journal file systems perform their own logging
of data changes, which is unnecessary for the database system and
leads to performance reduction."
Q: I am not familair with raw devices, so I was using XFS, because I
did read it was suitable for large files, like the ones I use with
MaxDB. The paragraph above put me think again... If I am not using Raw
devices, does this mean that I should use Ext2?? what about server
restarts? who will protect the integrity of my log and data files?
I would appreciate very much your comments on these topics.
Thanks a lot,
Martin
