Redo Logs - Raid 1 or No Raid
Title: Redo Logs - Raid 1 or No Raid Hello all Oracle 8.1.7 Windoze 2000 Archive Mode - OLTP System Which do you think is a better set up for the Redo Logs: 2 Groups on 2 Raid1 or 4 Groups on 4 separate non-raid disks? Granted you gain fault tolerance with the mirriored pair, but is that really needed if you multiplex group members over 4 different disks? As usual we are working with clients that have limited number of disks to work, so 4 Raid1's is not an option ;) Does anyone have multiple log groups on the same physical drive(s). For example, 4 log groups, 2 members each, with group 13 on drive A, and 24 on drive B? Does this really gain you anything? Any ideas and comments are welcome. Thanks for all the help.

Multiple Datafiles and performance?
Oracle 8.1.7.4 Win2k What is the consensus on datafile sizing and the impact/overhead multiple datafiles have on performance? For example, if I have one 2.5g datafile, and three 1g datafiles, and I need more space, would it be better to increase the size of the 1g to 2g or add another 1g datafile?. Is it better to keep them all uniform in size? I would think having multiple datafiles that could be spread across drive volumes would be beneficial, am I wrong?

RE: Multiple Datafiles and performance?
Thanks for the knowledge dump everyone! Based on your responses, I'll make the recommendation that our client go with 3 2.5G datafiles. They currently are 1 2.5G and 2 1G datafiles for the tablespace in question. Most of our clients have less than 30 datafiles, and I doubt will find any over 50. (slightly less than 1150 ...whew!) Index files are separated from data. The datafiles in question were data, and not index files, but they are on RAID5. We got them add 2 more RAID1's, so they are up to 4 RAID1's and 1 RAID5. We have the Indexes on a RAID1, the OS/Oracle on a RAID1, the remaining were on the RAID5, including RBS and REDO. We are moving the Redo Groups to the other RAID1's (one group on each). We could move the RBS to the OS/Oracle drive should contention is still an issue. I've been walking around with ORACLE 101 - Performance Tuning duct taped to the back of my head for about 4 weeks now trying to absorb as much as I can. It's got me looking at every change we make and it performance consequences. The number/size of datafiles was one thing I couldn't track down much info about in relation to performance. We've changed the app to increase use of bind variables, so we're making progress. (It helps that we have an Oracle DBA on each development team). We're making a lot of progress, an the info from this list and the recommended reading has played a big part in helping me get, not just changes made, but the right changes made. Now, if I could just learn to make more focused and cohesive sentences and yeh,uh what I just said. Once again, thanks for the help David Phillips Support DBA -Original Message- Sent: Thursday, August 07, 2003 10:45 AM To: Multiple recipients of list ORACLE-L Dave, There is little about the size of datafiles to affect the performance of SQL statements, but there is much to affect the performance of backup and restore and administration. Uniform-sized datafiles simplify the administration of space. The speed of a backup or restore is a function of the largest datafile, so although files can now be sized in petabytes, it is not a good idea to do so. Personally, I stick to a max size of 2-8 Gbytes, depending on overall database size. Far faster to backup/restore lots of smaller files than to have one 500Gb monster holding things up. Also, if your storage subsystem isn't already implementing RAID-0 striping, then hand-striping multiple datafiles across volumes could help performance. Again, in that situation, many smaller uniform-sized files make the job easier than a few larger odd-sized files. Hope this helps... -Tim on 8/6/03 1:14 PM, Dave Phillips at [EMAIL PROTECTED] wrote: Oracle 8.1.7.4 Win2k What is the consensus on datafile sizing and the impact/overhead multiple datafiles have on performance?

RE: Multiple Datafiles and performance?
Gee, that question sounded a whole lot better when I wrote it yesterday than it did this morning when I saw it. :) Maybe I should be a little more vague.:) The problem is there are a couple of things I am trying to accomplish. We have clients that use our application that have specific performance issues which I am working to improve. The other issue is to provide recommendation to development/tech staff on initial setup of database/tablespaces/datafiles etc.., along with hardware recommendations for our application. So, that being said, I'll try and ask better questions. The environment is W2K, Oracle 8.1.7.2 or higher All tablespaces are LMT Most disk config's are 1 (or 2) Raid 1 along with a Raid 5 for basic systems. Most operate application 24/7 Questions: 1) Is there any advantage to uniform datafile sizes? 2) Is there any advantage/disadvantage for say 4 1G datafiles vs 2 2G. (Other than time to recover from datafile loss) It is probably safe to assume that the datafiles exist on a RAID 5. (for now) 3) Why the recommendation to take a Win2k datafile to just over 2G? For future apps I am pushing for optimal recommendations that go for more raid 1 sets or raid 10 over the Raid 5. This should allow for more flexibility for spreading out the i/o. Thanks for your patience and all the help. David Phillips Support DBA BAARF Member #30 -Original Message- Sent: Thursday, August 07, 2003 9:59 AM To: Multiple recipients of list ORACLE-L Win2K. If you decide to increase the filesize, do it to more than 2G (doesn't have to be by much). Of course, you didn't mention autoextend so this may not be an issue. Also, just how many physical disks do you have? Logical disks are not the issue. If you're going to get any increased performance you should be putting the second datafile on a second physical disk. Any how come you're not using some sort of RAID device (or don't you have your logical drives striped across your physical drives)? There is no easy answer to your question without an understanding of the reality of your disk layout.

As for the file size, I can not say because I have not tested it, but I think it should have no real impact compared to splitting it.

Oracle 9i vs SQL Server
Title: Oracle 9i vs SQL Server I know this topic has come up before on the list, so I hesitate to kick it again.(I hesitatedI didn't say I wouldn't :) I know there are cost issues, as well as skill set questions (do you have Oracle skills/MS skills) in house. My company has an App that runs on Ms2000 OS. (Dbase connections through ADO/OCI). It is capable of using Oracle 8i/9i or SQL Server 2000 on the backend for the database. Clients have the option, though we 'recommend' for the higher volume clients. The app receives status information from objects. There can be anywhere from 50 objects with 3 clients stations active all the way to 20,000 plus objects with 50+ client stations active. It's mainly OLTP in nature, with daily batch reporting. I'm and Oracle DBA who is learning MS SQL Server 2000 (because I'll have to support customer issues with our app.) I have confidence that Oracle will handle the load, but what about Sql Server 2000? I remember reading about read write contention issues with SQL Server, is that still a problem? What are the weakness/problem issues with SQL Server? Any opinions/comments would be welcome.
