Hi ,
I already made new_wire_settings to 0 but I had no changes.
I don't always have acces to the machine and I wonder if the Pb was not with
the filesystem.
On the ES47 , I've a smartarray 5 with a Raid 5 volume for the database on
AdvFs
on the DS20 , I've a RA3000 with a raid5 volume for the database but in Raw
Device .
could it be the Pb ?
I effectively also suspect a vm Pb. I don't know if , with sybase , it's
preferable
to use ssm_threshold to 0 and to set gh-chunks or if I must leave
ssm-threshold to the default value.
ESC:wq
