Where can one find some information about Oracle's market share in the
various O/S markets. Like, UNIX,LINUX,NT etc.

Quick IO gives you pre-fetch capabilities similar to EMC devices, of course, not
nearly as good, but it certainly does help on reads.
If you
have Veritas license, Quick IO is great. But raw is certainly still the
most effective. But Veritas gives you 95% of the advantages of Raw and
That would certainly work, although the time your typing, the datafile may
have changed, and thus your aborting older transactions. That is if vi can
even open the file as it has file open limits.

Title: Crash Recovery
Hi All,
I have an interesting problem, on one of my databases, a data warehouse, a killed session was taking too long
to rollback. It was time for the backup, and I had to do a shutdown abort.

It's always a good idea to include your platform, OS version
and most importantly, your Oracle version.
Since it's a DW, I'm guessing that the session in question
was doing parallel DML, and it's an older version of Oracle,
which does not have parallel rollback capability. ( forget

Hi,
Oracle was doing full recovery in older version during crash recovery
( I guess pre
7.3, but I'm not sure). But now, Oracle does not do full database recovery
during
crash recovery. Some un-recovered blocks are recovered when a user
tries to use
them later. So, if your online log files are

I've had something like this happen to me.
My solution was to make TEMP larger;
after enduring the LONG wait for recovery
to complete.

Since RAID5 means that data is striped, of course read performance is OK. As
soon as you talk write performance, however, RAID5 becomes something of a joke
since it was invented back in the 70's to offer a cheap alternative to the fast,
extremely expensive disks offered by IBM back then. So the
1 for PCI NVRAM for swap and online redo
I totally buy into using this sort of technology for online redo, but using it for swap just seems silly. You shouldn't be swapping anyway, and if you are it's much cheaper to buy ram than to buy a solid-state disk.
64 bit slots allow for (max) 350

First off, I cc'd the list on this. When posting a

George,
Agreed about it being silly for swap on a *nix box, but if you're
running on a brain-dead OS that is going to page stuff out
uncontrollably (NT/W2K) even with lots of available memory - its still a
good idea to give the OS some pagefile space on NVRAM.
Ahh My lack of knowledge of

Gary,
Here is where we have to know more details.
a 9 drive array on a single channel sounds like your peak I/O rate for
reads would be throttled by the controller channel speed. Now, if the
SCSI interface is ultra 160/m, and the drive support a sustained rate of
20 MB/sec - you're not pinched.
