RE: Backup Strategy
1. If you can afford to lose data from the time of the last backup, then you are right. However, I even put those databases on 24x7 mode whenever possible because (1) Developers, like DBAs, work strange hours in the night and day and would probally like to have access to the database. (2) You never had a developer be pissed off at you because you couldn't restore one table without having to wipe out all the work he or jack did earlier today. (3) How can you truely test a 24x7 application on a non 24x7 Oracle database when now the SGA differs between the two machines? 2. I am a strong believer of the KISS philosophy as well, you guys haven't seen my users! This, however, should not apply to us as DBAs whose job is to know DBA related commands.

Re: Database will not shutdown in Normal or IMMEDIATE mode
You can do an offline backup with shutdown abort. But anyway...see if there are any Oracle processes using CPU and go from there. There was a couple of bugs in that version of Oracle in which one (if memory serves me right) hangs on shutdown immediate if the number of processes were reached and the second bug had to do with the Archiving process spawning a lot of processes.

The whole reason behind posting your reasons were to show some examples as to why you would use a 2k block size. The reason I suggested 2k is that if they face performance problems (which usually does happen with a 2k blocksize), there are other parameters and means to use to offset the negative performance hit.

RE: Veritas Quickio and DB_BLOCK_SIZE
Hi Christopher, Like I said, Oracle experts can argue this issue until they are blue in the face, kinda like the Certification debate. Without any information on the data or application, I suggest a 2k block size. Everyone is entitled to thier own opinion, and I hope the author of the original post becomes successful in choosing his/her block size. By the way, you are agreeing and disagreeing with Jonathan Lewis at the same time. The index efficiency on small block size is Jonathan's point he made a couple of years ago when he was stating why he recommends a 2k block size on an OLTP type database. The other index point (scanning an index on a small block size) is from Thomas Kyte on the same thread...If you disagree with him, you can write him an e-mail so you can correct him. I hope you can appreciate the irony. Regards, Satar PS Nice website, I like the goth look!

Re: Veritas Quickio and DB_BLOCK_SIZE
Hi Jonathan, Sweeping statement...maybe. It all depends on your application. That's why I put an emphasis on his/her application (meaning both physical structure and data) requirements. As a GENERAL rule of thumb, I (personally) suggest (if possible) 2k for OLTP databases. It's like if you ask me what car to buy, I would say a "Honda". But if you were to tell me that you need speed, style and sex on wheels, I would suggest a Benz. You and I, (especially you!) can argue the benefits/disadvantages of using 2k block size...Which I don't care to do. I've put the benefits/reasons of a 2k blocksize at the bottom of this reply just to show some reverse examples of the ones you replied with. Some of the reasons should look familiar to you! ;) Regards, Satar 1. The OLTP app has lots of small rows (<2k) 2. The OLTP app does massive scattered reads (you don't full scan in OLTP). It reads a block here, a block there based on some primary key (after doing lots of scattered reads to walk an index structure) 3. The OLTP app has 1,000 connected users -- each wants their current row(s) they are using in the cache. 4. A smaller block size in a database that does lots of scattered IO's (eg: an OLTP system) and random keyed reads can definitely benefit from smaller blocksizes. 5. The indexes for the critical access paths fit exactly into an N-layer tree and allow an optimum buffering strategy when memory is limited. 6. In almost all cases the data for a single index value will be (significantly) less than 2K and will all be found in the same block. 7. Memory is at a premium. --- Jonathan Lewis <[EMAIL PROTECTED]> wrote: > > That's a fairly sweeping statement to make without > any justification - after all, at 2K: > > The block header is a much larger percentage > of the block size - so you lose space. > > The probability of wasting space from the > PCTFREE > setting increases - so you lose space. > > The memory overhead due to x$bh is fixed per > block, > so you use more memory to hold the same volume > (block size x block count) of data. > > Index depth may increase through having fewer > entries per branch block. > > Latch activity is likely to increase on range > scans > because leaf blocks hold fewer entries - you get > the same effect on tables with clustered data - > and the effectiveness of IOTs will particularly > be > reduced. > > > Jonathan Lewis > http://www.jlcomp.demon.co.uk > > Host to The Co-Operative Oracle Users' FAQ > http://www.jlcomp.demon.co.uk/faq/ind_faq.html > > Author of: > Practical Oracle 8i: Building Efficient Databases > > -Original Message- > To: Multiple recipients of list ORACLE-L > <[EMAIL PROTECTED]> > Date: 02 October 2001 21:56 > > > |If your application allows it, and if the > Application > |will not change in the future, then use a 2k block > |size for OLTP database. > | > |If you are not sure on the application needs, then > |stick with 4k to be safe. > | ______ Do You Yahoo!?

Re: Oracle -> SQL Server
Hi Christopher, It can be done, Usually from third party software companies. For example, Check out: http://www.datamirror.com/products/tserver/ Back in the day (1996), Oracle had a "Mainframe & Integration Technologies" group that handled such problems. You might want to contact Oracle and see if such a group still exists and if they can provide you with a solution.

Re: Oracle Open World
I never cared for Oracle Open World, it was just one big commercial. The only cool thing about it, is seeing all my friends who started their own Oracle consulting firms or working for someone that I know. Plus I'm a shop-a-holic and I spend way too much money on Oracle clothes and junk, like key-chains, license plate frames, etc. Then I kick myself on why I spend so much money to advertise other people's products.

Re: Network Appliance Options
Hi Kathy, I attended a meeting with NetApp's Database Marketing Manager 2 to 3 years ago. I discussed with him on how the technology of the NetApp filer works with Oracle database environments and why he feels that NetApp is a solution for Oracle databases. The meeting was a result of me not supporting NetApp in any Oracle environment. To keep a long story short, here is what I learned and now believe: At that time, what was told to us by him was that they (NetApp) were not ready to be pushed in the market of OLTP type of databases because of performance limitations of network systems. I learned that NetApp is a valid (maybe not the best solution) storage solutions for data warehouses and databases where performance is not a critical requirement. NetApp is an expensive solution compared to other storage solution providers. The markup on hard drives alone were insane. However, the administration of the netapp filer was very easy to understand and perform.

Re: Optimal Disk Layout??
Hi Walter, It looks like you're having a bottleneck on your controller during a hot backup. This is a result of (1) reading the data then (2) writing the data and compressing the data within the same controller. To answer your questions: 1. During RAID 5, all your disks are being written to and parity rotates on each disks. You can do a search on RAID levels on the web. One thing to note is that a RAID 5 needs at least 4 physical drives to work efficiently. 2. Since you are running a single A1000 with 8 slots, I would avoid the RAID 0+1 idea. Keep the RAID 5 setup unless you go with 10 drives, then go for RAID 1+0. Alocate a couple of drives for redo logs (on seperate internal disk bus within the A1000) and multiplex the redo logs on the two drives. Keep a drive for the archived redo logs, you can even use a bigger hard drive that has the same form factor as the 9GB hard drive. Try to squeeze a Hot Spare in as well. seperate the RAID 5 drives between the two internal disk bus of the A1000 as well. Look into backing up your database to a TAPE device instead of hard drives. With a 8GB database, you can restore your database in 10 minutes with a DLT 8000, just make sure the backup software binaries and database resides on a sperate system on your network. Your best bet, if you can afford it, is to return the A1000 and get a A3500, which comes with 2 D1000's. Buy the additional controller for redundancy and do a RAID 50 or 10. This is the best bet because of the redundancy on the conntroller, disks and internal bus of the system. Also implement the TAPE backup system. I believe the A1000 is a 10 slot (for 9GB drives and some 18GB drives). If it is only a 8 slot storage, make adjustments accordingly, keeping the internal disk bus in mind. Lay out your disk: Slot 1 - RAID 5 DRIVE Slot 2 - RAID 5 DRIVE Slot 3 - Archived redo logs Slot 4 - Redo Logs (Members A) Slot 5 - EMPTY Slot 6 - RAID 5 DRIVE Slot 7 - RAID 5 DRIVE Slot 8 - Redo Logs (Members B) Slot 9 - HOT SPARE Slot 10- EMPTY If it is a 10 slot and you decide to go with 10 hard drives, implement RAID 1+0 to increase write performance. Use the Hot SPARE disk as an extra disk to throw junk into. Hope this helps. Let me know if I confused you more or if you need additional info.

Unfortunately, they put a lo-jack system (cell phone) on me, so I am available to them 24/7. To date, after 1 and half years working for this company, none of my databases have experienced any problems. I like to think it's due to my expertise, or maybe I'm wrong, and it's just luck. Also, I hope this doesn't come across mean or unappreciative, but if you remove yourself from the list, you will give yourself so much more time to tackle the work at your shop. As you might have noticed, I removed myself from the list for 7-8 months while my company gave me the responsibility of UK's databases. I needed that time to go to the UK, configure and tune the datbases, setup an automated backup and recovery procedure, post application tuning and provide remote support, along with other things. I do have to agree with Christopher Spence, if this is a in-house Development, or continued developed oracle application environment, then of course you will need additional people to help you out. I initially replied to this post, because I was given the same opportunity to bring in another DBA for the UK. I chose to do the job myself, eliminating a part-time DBA that was positioned in the UK and also removing the need for Oracle Support in the UK (which is extremely expensive compared to the US).

Re: 2nd DBA or ?
If we lived in a perfect world, where the employee matters, then I would hire an additional DBA to share ideas and responsibility. However, since we live in a capatilistic world, I would do the job by myself for the following reasons: 1. Management will see one of you as being redundant during financial problems because there was one person doing this job before, therefore they can get rid of one of the DBAs and still be ok. 2. Mamangement acknowledges that there is a possible need to hire an additional person, thus acknowledging that you do the job of two people. This is a benefit to you for asking for a big pay increase. 3. Hiring Oracle consultants and purchasing software are tax deductible to the company as opposed to paying a salary to another person and providing them with Health Care and Office Space. At least in the USA. 4. If you hire a entry-level DBA, chances are that he/she will learn his skill set from you and then move on to bigger opportunities (which puts you back to square one) or he/she will just stab you in the back to try to get your job.

Re: Error in creating tablespace
Ashraf Jan, Create a directory within the C drive labled "ORADATA". Then in svrmgr30, login as system, then type: CREATE TABLESPACE PAYROLL DATAFILE 'C:\ORADATA\PAYROL.ORA' SIZE 10M; make sure to use the semicolon, not the /. I know it sounds stupid, but just do it please. Please let me know what happens. For some reason, Oracle is having a problem writing to the FIRST block, which indicates that something is preventing writes to the root directory.

Re: Error in creating tablespace
Salaam Ashraf Jon, It appears that Oracle has a problem writing to the C drive to create the datafile on the very first block. This error is usually the result of a size issue over 4gb for the datafile or a file that has been autoextended. In your case, it appears it doesn't like the command (maybe some character is being passed through the command?). Delete the file and re-try it again. try doing this in svrmgrl80 and put a ; at the end.

RE: Looking for 24 X 7 Design Considerations
I'm pretty much in the same boat. All my global databases are doing well. There are virtually no database issues. People wonder why the company pays me so much money for doing nothing. However, I still get those calls at odd hours of the day/night (because of the time differences) from system administrators that think something is wrong with Oracle. Also, management loves to implement software upgrades/patches during the Holidays or weekends. I'm just glad that I live in California, where a recent law (Assembly Bill 60)forces my employer to pay me by the hour. Overtime and off hour phone calls are my new best friends!

Re: Looking for 24 X 7 Design Considerations
All the databases that I have worked on or been responsible for, have been 24x7. Here are some suggestions: 1. Know the requirements of your environment in regards to UPTIME. Have it documented. The best practice that works well is Service Level Agreements, if there is none in place, implement them. There is a world of cost differences between systems that can be down for 2 hours to those which can't be down at all. 2. In high availability databases, a Hardware cluster configuiration is highly recommended for 2 purposes: (A) Fast recovery and (B) Software upgrades (both APP and DB). 3. If you do not have a Test server, buy one! 4. Make sure that everyone (network Admins, DBAs, System Admins, etc.) has a way to communicate with one another. I suggest Cell phones as apposed to pagers. 5. Kiss your weekends and Holidays good bye!

RE: Tablespace layout
Title: RE: Tablespace layout Hi Cherie, Just shove all your data on a RAID 5 (great for data Warehouses) and forget about it. If that is not possible, then stick with what your DBA team has stated about everything being ok as long as the extents are multiples of one another. Regards, Satar Naghshineh -Original Message- From: [EMAIL PROTECTED] [SMTP:[EMAIL PROTECTED]] Sent: Tuesday, August 28, 2001 7:27 PM To: Multiple recipients of list ORACLE-L Subject: Tablespace layout I've been thinking a lot about our tablespace layout for our data warehouse. Our warehouse is approaching 200Gig and is almost out of space on disk. I'm getting another 75 Gig this weekend and am trying to plan the best use for that 75Gig. Our current data tablespace layout is that we have two tablespaces for small, medium, and large data tables and the same for indexes. So it's something like this: SM_DATA01 SM_DATA02 MED_DATA01 MED_DATA02 LG_DATA01 LG_DATA02 SM_IDX01 SM_IDX02 MED_IDX01 MED_IDX02 LG_IDX01 LG_IDX02 I think that theoretically, all of the tables in each of the tablespaces were supposed to have the same sized extents when they were originally created. However, over time, there are multiple sizes of extents in the large and medium tablespaces. Even though we show significant free space, it is fragmented and coalescing can not put together enough contiguous space to reuse a lot of the available space. Our largest tables are partitioned. However the partitions are not split out into separate tablespaces but go into the same medium and large tablespaces as non-partitioned tables. Theoretically, I suppose that this is not a problem if, when partitions are dropped every month, the resulting space is reused 100%. I'm not sure if it is. Here is my question. My DBA team members feel that it's fine to have tables with a variety of extent sizes in the same tablespace as long as they are all multiples of each other (50, 100, 400, 2000, etc.). My concern is that this setup is fine when the smaller tables need to extend but when the larger tables need to extend, they can't pull together enough contiguous space and I keep having to add more. I'd prefer to have only one size of extent in each tablespace and keep it very pure that way. Then I know every single extent can be reused. So I am considering increasing the number of tablespaces so we have something more like this: 1kdata 10kdata 100kdata 1mdata 10mdata 100mdata 1000mdata 1kidx 10kidx 100kidx 1midx 10midx 100midx 1000midx I would also probably split them out into at least two tablespaces for each level. Maybe not for the smaller sizes, but for the larger sizes. I have several issues I'm trying to keep in mind. One is the ease of maintenance for initial creation and ongoing upkeep. I don't want to have too many tablespaces if I don't need to. Another issue is mean time to recover. If we lose a single tablespace, I'd prefer to have to recover fewer files. The maximum file size we are using is 2Gig. We need to keep our recovery time under four hours total. Probably the biggest issue I'm facing now is the sheer size of the large tablespaces. They are so big and bulky that it's almost impossible to reorg them or even just clean them up. I think that if I had more smaller tablespaces, I would have more options. This database is still at 8.0.4 and it's going to be a while before it can be upgraded so that limits my options for reorging as well. All cleanup has to be done in a series short Sunday windows. I don't have the luxury of a tool for doing this reorg so have to do it manually. Another issue is partitions. We are dropping the old partitions on the main fact table once a month. We are not currently planning on dropping any of the other partitions. The tables have a variety of partition names and schemes. Some are partitioned yearly, monthly, quarterly, half-yearly. There is no consistency. I'm debating whether I should split each partition out into it's own tablespace. That would be almost a hundred tablespaces. Or just the table that we're dropping partitions on monthly. That would be about 50 tablespaces. Or should I just leave them all in the same tablespaces as non-partitioned tables? We are using Sun Solaris 2.6 on an E10K. We have EMC disk and Veritas file manager. Using version 8.0.4 of Oracle, as I said. Using RMAN and Veritas for backups. Any feedback, ideas, suggestions, things to watch out for, think about, etc. would be greatly appreciated. This is going to take a lot of time and effort to do and I don't want to get all the work done and find out it doesn't work as well as I hoped and have to redo everything.
