management was heavily invested in making the system go live as is... since they were heavily involved with the design. They designed it without a DBA. OLTP system, main order table had 23 indexes on it.

Re: Veritas Quick I/0 and Oracle/ Asycnchronous I/O
I disagree wholeheartedly with this statement Alex. How can you make this statement without knowing the situation? (You seem to be becoming the resident troller in this group! Sorry, but it does appear that way.) In spite of all evidence and repeated warnings, management often does not allow the most reasonable solution - preferring instead to play ostrich and simply throw hardware at the problem.

Re: Veritas Quick I/0 and Oracle/ Asycnchronous I/O
Kevin's point is probably, that if each index has a depth (blevel) of three, then each index will add three LIO's to any DELETE or INSERT statement. For UPDATE statements, only the indexes on the updated columns count. LIO's mean cpu usage and latch pressure, which is why we want to mininize them in many situations.

But they do want to see what they can do. Obviously, the programs which collect the data from BPM's and other sensors needs to do some buffering. But when they dump to the database I need the writes to happen as quickly as possible. The current method of handloing this via ring buffers and doubly-linked lists.

Paul 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. I should have called it pagefile - not swap.

Re: Veritas Quick I/0 and Oracle/ Asycnchronous I/O
Hmmm so it's a pci only interface, so I can't use it with my Enterprise Sun systems, and drivers for Tru64 don't yet exist, so unless you're running Windoze, AIX or Linux, you're out of luck. That's a real bummer. Anyone use Imperial's solid state disks? I played with them at a clients a few months ago. I had a few problems with DMP but they were otherwise very impressive. Fiber interface, so you can put them on a fabric switch and share them between your hosts. http://www.imperialtechnology.com/ On Sunday, June 10, 2001, at 06:05 PM, Paul Drake wrote: Christopher Spence wrote: AWESOME looking website Walking on water and developing software from a specification are easy if both are frozen.

I was thinking about a pair of these for (oracle mirrored) online redo logs. 2 units of 1 GB each would have plentry of room - half for redo and half for swap. If it works really well, get a 3rd unit for swap alone - but it would have to be on another bus channel. this is where having multiple PCI bus channels (e.g. 4) really makes a big difference. 1 for internel storage (ultra 160/m SCSI) 1 for external storage (fibre channel or ultra 160/m SCSI) 1 for gigabit network cards (and backup fast ethernet card) 1 for PCI NVRAM for swap and online redo 64 bit slots allow for (max) 350 MB/sec transfers. wow. cdw has these (special order) - http://www.cdw.com/shop/products/default.asp?EDC=209969 the one listed looked like it supported a 32 bit interface. $2500 each. ouch. sounds like a good way of justifying an adequate number of hard drives for online redo.

I can't help picking at one of their 'success' stories however. This is from their website: This customer is running an SQL database on a DELL 6350 quad-processor system, with a fiber channel storage system. Under this configuration the time taken to access information from the database was taking more than seven minutes. This performance was unacceptable to the organization. Performance By introducing the Platypus Technology solid-state storage system to the SQL database, the time taken to access information was reduced from seven minutes to a maximum of two minutes, representing a threefold increase in performance. The result is that the Platypus Technology solution is allowing far greater productivity from the substantial ERP investment the company has made. --- This appears to be one of those cases of management throwing money (hardware) at a problem, but they're still stuck with the problem. Taking response time down to 2 minutes still sounds unacceptable to me. There are bigger problems here; the customers system is in serious need of tuning. I just *had* to point this out. Had too many damagers want to solve everything by buying HW when they have no idea what the problem is.

RE: Veritas Quick I/0 and Oracle/ Asycnchronous I/O
Title: RE: Veritas Quick I/0 and Oracle/ Asycnchronous I/O It works just fine, but I think you will actually get more performance out of a solid state device. Take a look at platypus.com, they have a SSD device that plugs into the PCI board in your computer... They claim over 60 MB per second of data transfer. And the drives can go up to 500 GB... I think they can even daisy chain them if you need more. You will only need enough space for the redo logs, control files, and a locally managed tablespace that holds the data. It only took us about 20 minutes to install one on a Sparc Ultra 5 for some testing. And it works great. Nick -Original Message- From: MacGregor, Ian A. [mailto:[EMAIL PROTECTED]] Sent: Friday, June 08, 2001 12:31 PM To: Multiple recipients of list ORACLE-L Subject: Veritas Quick I/0 and Oracle/ Asycnchronous I/O Will Oracle use the Quick I/O capability of Veritas on database writes; that is, will it bypass any file system buffer cache and write directly to disk? Is the implementation of asynchronous I/O imnproved in Solaris 8; does one have to use raw disks or does it now work properly with UFS or Veritas? I need to configure a machine to provide for the maximum number of transactions per second. Our Accelerator Controls folks are at it again, testing how much data they can push into Oracle. They have backed off the plan of having 6000 Beam Position Monitors sampling at 120 Hz write into the database; although., 720,000 transactions per seconds might be fun to try. But they do want to see what they can do. Obviously, the programs which collect the data from BPM's and other sensors needs to do some buffering. But when they dump to the database I need the writes to happen as quickly as possible. The current method of handloing this via ring buffers and doubly-linked lists. They want to look at replacing the lists with an Oracle database. Our initial tests will be done using a 4 processor ES-450.
