It would be far easier to modify the requirement than to do what you are thinking of doing. Adding columns to database tables indicating that a record has passed it's retention policy and thus, is not included in queries, would be a much easier solution. Or, simply moving these records to historical tables in the database - and NOT deleting them from the system - is a much better solution. The data is always accessible and not available in the current tables.

When the retention period is reached, the data should be deleted, but then at a later time, some user might request for this purged data. So it must be possible to retrieve this data. This is the strategy we have designed for this. When the retention period is reached, move the data from the main database to an offline database. Then delete the data from the main database. In the offline database, we cannot again keep it from long, so it has to moved to tapes. Now my question, how can we move this data to tapes and at the same time retrieve data from the tapes based on dates. i.e, the user will ask for the data on a particular date, so it must be possible to retrieve data from the tapes based on a date and load it to the database tables.

The contractor must follow your methodology and give you the same documents as your internal IT teams. On the DBA side, you should expect : database architecture, logical data model, physical data model, naming convention, backup and recovery guide, security guide, a benchmarking document (if some benchmarking was done). --- dist cash [EMAIL PROTECTED] a écrit : We have a application use ORACLE 8.1.6 and Forms 6i.

Re: will the Return Order of rows change with time ?
When doing many select you should have the same order but this is not guaranteed by Oracle. The only official guaranty is to use an order by. After an export/import or a move, you have the risk that the rows will not be in the same order. How big is the table ? There is no unique id for the customer ? --- Ratnesh Kumar Singh [EMAIL PROTECTED] a écrit : Hi I have a very large DW table in which there are only inserts and NO updates/deletes.

ETL architecture
Hi, On all DW project I've been, the ETL tool was on the database server containing the DW database. On the current project, the architecture team has decided that the ETL tool (Data Junction) will be on its own server (Windows) to service all projects needing ETL processing.

RE: Warehouse design: snowflake vs star schemas
Snowflake is often used because people still want to normalize (and save some disk space !) which is not the way to go to ease query. If you do an hybrid data model, your loading will be easier as you will have less problems to solve. I agrre with you, the complexity comes from the number of sources and their quality. But, from experience, at my last job, the DW has designed an hybrid data model to ease the ETL processes. Let me tell you that the querying and reporting was painful and slow. We have redesign it in a more formal star schema and we had some real challenges to load the DW. On the current project, we have 15 sources (excel, cobol, Oracle, Clipper, DB2/MVS, Nomad,... ) we are doing a prototype with an ETL, we will have fun ! It is feasible just to have a date column in the fact table. That's what they had done at the previous job. I do not recommend that. If you carefully do the analysis, you'll see that the users want to manage all kind of special events like season, national day, F1 racing (in Montreal, a beer company is checking if beer is more sold during the week-end Grand Prix). Also, often the fiscal year do not match the calendar year. So there is plenty stuff you may want to track with the time dimension. Using a generated key or the date value as the key is a good question. On the theoritical side you should use a generated key. I've used a date field without problem. --- Alexandre Gorbatchev [EMAIL PROTECTED] a écrit : Stéphane, Thanks for response. I have always discplined myself to use star schema and never snowflake.

I mean ETL to load data _INTO_ data warehouse. Of course, complexity is mostly determined by sources, but still I'd like to know if there is any general influence by DW's data model. Another question. Is it feasible to make date dimension or just use date column? For example, Oracle Discoverer can work with date columns using hierarchies Y-M-D and similar.

Re: Cost of joins
It depends on what you're doing. The use of a join technique over another depend on how much data you need to access. If you read very few information from both tables then a nested loop is the fastest way to get data. To use a nested join at a cheap cost you need a good index on the outer table. On the other hand, if your query output contained allmost all data from both tables than an hash join or a sort merge is better than a nested loop.

RE: Another datafile sizing question
It's late at night maybe that's why I do not understand your answer but I do not see the link between LMT and the number/size of datafiles. One reason of multiple datafiles id to spread IO but since nowadays a majority of sites goes on huge disk box using raid 5 (that's what we have, the unix guys are the IT master here) multiple files is less meaningful. What I liked is a file politics where you restrained the number of file size. Here we have from 15M up to 8.5G file size with all the possibility in between. I'm trying to standardize all that. Another factor to consider is backup and recovery. Restoring a 10G file will take more time than a 2G file. In your case, if file placement is not possible than go for a 800M file and use a second one for the future growth. -- DENNIS WILLIAMS [EMAIL PROTECTED] a écrit : Darren - My advice would be to read up on Locally Managed Tablespaces (LMT) and uniform extents.

Of course, things won't change as fast as an export/import but it's certainly less work to do. --- [EMAIL PROTECTED] a écrit : John, Someone asked a question a month or so ago about changing PCTUSED and PCTFREE: When do the blocks go back on the free list, when the 'ALTER TABLE ... PCTFREE N' command was issued, or did the blocks go back on the free list when the next insert was issued. I don't remember what my conclusion was, and IIRC, it wasn't definite. But, testing shows that blocks do go back on the free list when PCTUSED is increased to a a value greater than the amount of data in the block. This was on 8.1.7 on Linux. It's in the archives if you care to look for it.

Using Log Miner across all DB
Hi all, First post since I begin a new job. All my DBA contacts have played with Log Miner but none of them have deployed it in a production environment. We want to set up LogMiner to be used across all production DB (25+ db on Oracle 817). The way I'm seeing this is the following : - All db with a utl_file dir to create the dictionnary - There is a central location (DB and OS repository) to investigate, where we will copy the dictionnary and the redo/archived files (all file names contain the instance name so they're unique) - I've developed a package to simplify the dbms_logmnr procedures for the other DBA I've seen posts on Metalink where people where loding the v$logmnr_contents in a homemade table to speed up queries. Anybody recreating the dictionnary with a cron job ? Any comments ?

RE: ALLOCATION_TYPE USER or SYSTEM for a Locally Managed Tablespace ?
I'm not sure I understand what you exactly want but
here is what I do/believe.
Since 815 and up to 817, I use LMT with uniform extent
size. I kept the number of extents by objects below
100. On a 8K block size, you should not have more than
505 extents for an object because that's the number of
extent adresses Oracle can keep in a block (in the
segment header).
Yes, object fragmentation is as bad with LMT than
dictionnary managed tablespaces. You do not want
blocks to be half empty, in both cases Oracle will
have more worked to do (read more blocks) to read the
data.

Tablespace ?
Even though you control the extents with USER, the
underlying concept is still usage of bits (typically
5
x blocksize, unless you already had MINIMUM EXTENT
set
on the tspace before migration from dict=lmt).
Thus, probably (assuming you don't want to use
uniform), an auto-allocate policy is best to limit
the
possible damage from fragmenation (ie lost space)

Re: WG: Re: Data Warehouse on Windows
Hi, Sure that Sybase has not all the nice features Oracle has but I'm a bit surprised that you find it way too slow, do you have Sybase 12.5 ? 12.5 has interesting new features compare to 11.9 version. 20 users doing ad hoc queries ... I supposed you have a tool like Business Objects or Cognos and you're hiding the tables behind a user layer. Some typical queries involve joining 2 tables each holding 2 Million rows. Are you using dimensionnal modeling ? You can have a dimension with a million lines but it's very rare. Have you built aggregates ? The only good way to speed up queries in a DW is to pre-calculate the data. Have you investigate to see what is the bottleneck in your application ? Depending on it you may or may not solve it by using Oracle DW features : partitionnning, star join, ,... HTH --- Sackwitz, Antje [EMAIL PROTECTED] a écrit : Hi, Stephane, actually we have the database running on Sybase but there it is way too slow ( as I told everyone here before). The application has about 25 small and about 10 large tables. Data comes in every night about 100-250MB. We have just about 20 users doing 'ad hoc' queries to the database via a commercial tool. At the moment we have a test installation running on an IBM computer having 2 processors a 2Ghz, 2 Gig RAM. Some typical queries involove joing 2 tables each holding 2Million rows. Test situation will represent data warehouse after being 3 years in production. Well, now the query takes about 15-20 Mintues which is too slow for our sales people. I calculated, the machine scans about 80-1Mio rows per second. I thought, there are a lot of tuning possibilites in Oracle that are not available in Sybase. Our system can run on both RDBMS. So as we are buying a new machine for our database test environment I thought I better find out which is best equipment for Oracle as I expect people to learn that Sybase is not your number one when you go for a fdata warehouse. Overall we calculated, that we add new muodules over next couple of years so finally DW will hold 20 Gig data.

Re: Data Warehouse on Windows
In a datawarehouse you want to exploit parallelism as much as possible. So you'd better with many processors and independant mount points. As raid 5 is very popular because it's cheaper, you will probably put your data on raid5 but fight to put your redo on non raid 5 disk. Do you have a good idea of the architecture ? Will you load the data daoly, weekly, monthly ? You may end up with a design where the database is non archivelog and allmost all the loads are done in direct path with nologging , then putting the redo on raid5 is less important. --- Sackwitz, Antje [EMAIL PROTECTED] a écrit : Hi, I was asked to give some hint for the hardware for a data warheouse running on Win 2k and holding about 20-40 GB data.

Re: Rolling partitions

At my last client, I was surprised to see no time dimension in the datawarehouse but I was even more surprised to that there were no date at all in the fact tables of this datawarehouse. It was in a biotech company and the datawarehouse was developped by Oracle Corp. Time was having no meaning for the users (biologists). --- Jack Silvey [EMAIL PROTECTED] a écrit : Jared / all, Agree, date column in the fact is a bad idea. I have experience with a warehouse that had a fact table partitioned on a date column. This system does not use a date dimension, and queries are directly constrained on the date column in the fact. You are right, in this system, if you use a date dimension, you do not get partition elimination. You can get partition elimination if you use use partition key in the WHERE clause, but this setup has two major problems: 1) no true star execution, and 2) lack of flexibility. No true star execution: In true star schema execution the query visits all the dimension tables first, makes a cartesian join of all of the relevant dimension records, and use this dataset to select records from the fact table. This works since the fact table visit is usually the most expensive, and it is cheaper to do a cartesian join of dimensions rather than use the fact table as part of the regular query. Since the date column is in the fact table, the enduser must directly constrain queries against the fact. Therefore, this system does not use the STAR execution plan, since it must use the fact as part of the normal query and is not able to save it until the last step. This hampers query performance. Poor flexibility: This system is not flexible, since you cannot store date information other than just the date. For instance, since there is no date dimension, queries can't just look in the dimension table and see which dates comprise fiscal third quarter. The query issuer has to hardcode dates into the query, instead of saying where datetab.3qflag = 'Y'. Kimball talks about direct fact constraint on dates with an air of disfavor in his book about data warehousing. I am sure that these two problems are not the only ones, they are just the first two that leap to mind. Jack --- [EMAIL PROTECTED] wrote: This discussion raises an interesting question. Do your fact tables have a date column in them? If so, how do you correlate that with the date/time dimension table? If you use a local date column to control the partitioning rather than a PK from the date/time dimension, user queries based on the date/time dimension won't be able to use partition elimination.

In the next slide, you see the fresh new employee just hired from school who says I just develop on my laptop a program to prevent losing the passengers luggage --- [EMAIL PROTECTED] a écrit : Ok, this is kind of off topic, but it does have Oracle in it at least once. I just couldn't resist sending this to the list. How many of us have had an experience similar to this? I've had at least two I can think of. The worst was after a merger, and we went with the other companies more expensive, proprietary system for a data warehouse. (Ours was Oracle on AIX, theirs was TeraData on NCR ) The reason? And I heard this with my own ears coming from the mouth of a VP: It was a business decision. Our system is only 2 million dollars, and theirs is 11 million, so we're going with theirs. This from a business that hadn't made money in 4 years. - Shark Tank: Works, shmerks -- how much did it cost? This sysadmin pilot fish discovers that his company needs to distribute updates to a cluster of Unix servers. Simple enough, says fish. I write some scripts that copy the data out and append it to the files that need it. It all works well and it tests out great. But as the deadline for the rollout approaches, fish learns that the company has spent a six-figure wad of dough on a big commercial software package to distribute the data -- including a full-time engineer to run it. My scripts are ripped out and replaced by a set of four dedicated distribution servers running this giant package, says fish. OK, he can live with that. After all, his scripts are being replaced by four servers and a dedicated engineer. But there are implementation problems, and bugs, and the deadline is missed, and expenses on the project skyrocket. The dedicated engineer is spending all her time on the phone with the vendor's tech support, just trying to get things working. Meanwhile, fish's scripts are still humming along perfectly in the preproduction environment. Say, fish suggests to management, maybe we should forget about giant six-figure, four-server packages and consider implementing this simple, effective solution that actually works. And management turns him down cold. The reason? If we use a home-rolled solution, we won't have tech support, his boss tells him. And, as we have seen, we make heavy use of tech support for this problem. _ Can't get enough Tank?

RE: Free ware databases: which are worth the money?

Uncomplicated databases, with mid size volumes of transactions (say low millions) and some reporting queries?

Re: Data Warehouse design
Yes it is ok to have sequences as the primary keys. The dimension should not use keys from the source systems as their own keys. They must be independant. Also, since the PK of the dimensions are foreign keys in the fact tables, if using a non-generated key you will increase the size of the fact tables for nothing. I've never put relationsips between dimension tables. All the validation is done before the load in the staging area. --- [EMAIL PROTECTED] a écrit : Hi, I am in the process of designing the data warehouse. My Question is can I define the relationship between dimension tables. Like I have country,customer and time zone dimension tables. Can I add relationship between customer,country and time zone just to validate the data before load whether the country and zip code is correct or should I integrate the country and time zone with customer itself. If I integrate this. Is it going to affect the performance. 'cos for every record it is going to validate all these things before load. Can I create sequences for primary keys(fact tables and for some of the dimenasion tables also). Is it OK to have a sequence as primary key. I need your expert views on this.

Re: Analyze running twice as long after upgrade to 8.1.7.2
As John says, you can check on what Oracle is waiting on . It may not solve your problem, but can make the analyze faster. Since your fact tables are partitioned and since you're migrating from 8.0.4 that means range partitioning. If the tables are partioned by date and you do you allow update/insert in partitions other than the current one then you can analyze only the current one. At a previous client, only the current partition of the fact tables were analyzed after the daily load. --- [EMAIL PROTECTED] a écrit : We just upgraded our data warehouse from version 8.0.4 to version 8.1.7.2 of Oracle. We run on Sun Solaris 2.6 vith Veritas Quick I/O. We do an analyze compute nightly with a 10% estimate of our large, main fact table. Before the upgrade, the analyze ran for 45 minutes. Since the upgrade, it's run three times at a consistent 90 minutes. I am trying to research on Metalink but have not had much success. Why would this analyze suddenly run longer? I wouldn't think that analyze code is being modified much in new releases. All the effort would go into new packages like DBMS_STATS. Is anyone aware of analyze changing in 8i. Our analyze was of a partitioned table and was single-threaded, not parallel. I can see that it is still single-threaded. We really didn't change much during the upgrade. I added another datafile to the SYSTEM tablespace (on the same file system as the previous file). I also changed parallel_threads_per_cpu from 2 to 0. However, since we never did the analyze in parallel, I don't think it was an issue. Any other ideas? I'd like to be able to give our application owners some explanation.

IMHO, try to concentrate on 'problem' code - check V$SQLAREA at regular intervals to see the top 'buffer_gets' queries, you do not only have individual queries, you will also see (command_type = 47) stored PL/SQL procedures, and they may point you to bad logic; listen to users to. Fortunately there is a lot of terrible code that nobody really worries about. The first thing I would do in your case would be to put calls to dbms_application_info everywhere, setting 'module' and 'action' to identify 'atomic business processes' (if such a thing exists), then use coffee-machine information and a bit of monitoring to check what really hurts and concentrate on that.

Re: partition tables
You can use insert select , export/import, create as select to move data from a non-partitionned to a partitionned table. Partitionning helps in the management of large tables more than in speeding the queries. Will you delete data from that table one day ? Choose the partition key carefully. A partition with only 100 000 rows is pretty small. Since you have 10 000 000 rows in your table, you will have 100 partitions of 100 000 rows, it's way too many small partitions. --- BigP [EMAIL PROTECTED] a écrit : Hi All , We are thinking of converting one of huge table in to partition table .

Re: Limited SORT_AREA_SIZE
Hi, Asked you sys admin to boost the maximum memory allowable for a process. I had that error on a hp box. I do not remember the name of the parameters. Once the sys admin had changed the memory process parameters, processes were able to use way more than 150M of ram. You can increase the sort_area_size for a particular session with alter session instead of bouncing the db.

Re: Partition Exchange
The alter table exchange partition lets you transfer data from the partition of a partitioned table to a non partitioned table. It changes the adress in the data dictionnary, no data is moved, that's why it is fast. For example, I'm using it in a system to exchange old data with new data.

Re: data warehousing desing - to denormalize or not to denormalize -
A DW stores data in a denormalised fashion, that's one point that every body knows but it is also subject oriented. It is also developped one subject at a time. A DW is multi-subjects as a datamart is on one subject. From Bill Inmon From the data warehouse data flows to various departments from their customized DSS usage. These departmental DSS data bases are called data marts. A data mart is a body of DSS data for a department that has an architectural foundation of a data warehouse. The data that resides in the data warehouse is at a very granular level and the data in the data mart is at a refined level. The different data marts contain different combinations and selections of the same detailed data found at the data warehouse. In some cases data warehouse detailed data is added differently across the different data marts. Yet in other cases a data mart will structure detailed data differently from other data marts. But in every case the data warehouse provides the granular foundation for all of the data found in all of the data marts. Because of the singular data warehouse foundation that all data marts have, all of the data marts have a common heritage and are able to be reconciled at the most basic level. --- [EMAIL PROTECTED] a écrit : -- Gurelei [EMAIL PROTECTED] on 05/10/02 12:13:27 -0800 Jared, Thanks for the answer. I must admit my ignorance in terminology as for me data warehouse and data mart a pretty much the same thing except for size. I understand that data mart is smaller. The database I'm referring to could probably be described as data mart as it is going to be rather small - a gig or so maybe. Data Mart == summarized data from a Warehouse used to speed up query times. Main point to a mart is that by pre-aggregating the data the volume (and keyspace) are reduced. Mart's acutally increase total storage becuase they store the data more than once (Warehouse + agg'd into the Mart). Advantage is speed for the 90% of all queries that use agg'd data in the first place. -- Steven Lembark 2930 W.

Re: How to backup a data warehouse?
Hi, If my memory is good, it was in 1998-99 with Oracle 8, we were using stored proc with dynamic pl/sql. I do not recall that it was taking long. Everything was done with dynamic pl/sql : tablespace creation, partition creation,... Our partitions were not big, between 200M and 800M. Stéphane --- [EMAIL PROTECTED] a écrit : Stephane, So, what process did you use to switch over a non-read-only partition to read-only on a monthly basis? How quickly were you able to make the switch? How large were your partitions? Thanks, Cherie paquette stephane stephane_paquette@ To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] yahoo.comcc: Sent by: Subject: Re: How to backup a data warehouse? [EMAIL PROTECTED] 05/08/02 01:49 PM Please respond to ORACLE-L I've tested a setup like the one Tim is describing. We tested backuping with RMAN using incremental and doing conventional hot backup. We were partitionned by month and each partition was in its own tablespace. Only the current month was active so the rest was in read only mode. Since volume was not too big , we were still able to do a nice clean full backup during the weekends. --- Tim Gorman [EMAIL PROTECTED] a écrit : The short answer is that it becomes important to make use of the features of 1) range-partitioning, 2) read-only tablespaces, and 3) incremental backups with RMAN, and 4) a honking big tape library using media-management software. Range-partitioning allows tables and indexes to be spread across multiple tablespaces, usually by time. As data ages, inserts/updates/deletes tends to cease; it is usually the newest data that has insert/update/delete activity upon it. Therefore, as data ages, you can set the tablespace in which the partitions are located to read-only. As tablespaces are set to read-only, you can remove them from the regular backup list. It is important to take 2-3 additional backups for archival retention after setting to read-only, but the regularly scheduled backups can now ignore those tablespaces. Generally, I recommend partitioning according to your loading scheme (i.e. daily loads, thus daily partitions) and storing those partitions in tablespaces according to your scheme for setting them read-only (i.e. if setting read-only on a quarterly basis after aged 6 months, then create quarterly tablespaces to house all of the partitions from all partitioned objects in that quarter). The advantages of RMAN's incremental backup mechanisms should be obvious, but its usefulness depends on the nature of the application. At the very least, incremental backups will supplement the effects of the partitioning/read-only-tablespace scheme illustrated above. Using RMAN's incremental backup mechanism, at worst you would be getting the equivalent of a level-0 or full backup, if every block was modified during every backup cycle. I hope that would be an unlikely scenario, though... - Original Message - From: Terrian, Tom To: Multiple recipients of list ORACLE-L Sent: Wednesday, May 08, 2002 9:38 AM Subject: How to backup a data warehouse?

I worked with SAS several years ago. At that time it was a statistical analysis package. A scientist or engineer could load a set of test data into it and perform various arithmetic and statistical analyses. Today most of that can be done with Oracle or MS Excel. My point is that I would expect it to be heavily biased toward mathematical capabilities. Like Data Mining, which is all statistics. Learn what that term means. To learn Data Warehousing, I would encourage you to just do some Googling and find good tutorials. An excellent newslist is dwlist. Instructions: For help with list commands, send a message to mailto:[EMAIL PROTECTED] with the word help in the body of the message. The magazine http://www.intelligententerprise.com/ has some excellent information. I would search for Ralph Kimball. He is one of the leading figures in the DW arena. Look for some of his earliest columns on the magazine site. He also answers questions on dwlist from time to time. The main change you need yourself is to forget normalization. DBAs that can't get past that point don't last long in the DW field. In the early days the DW people would patiently explain the reasons to a DBA, but today there are enough DBAs that have made the leap that a hard-headed normalization bigot just isn't tolerated. It is much easier to just ask for a replacement DBA. The reason normalization isn't adhered to in DW is that users will be creating their own queries and they can't understand 10-table joins with outer joins, etc. A DW is usually loaded and then queried. Our DW is loaded each weekend and then queried all week. So a DW is deliberately denormalized and contains redundant data for ease of use. OLTP databases have no concept of time. A DW is all about time. To reconstruct what the situation is at various points of time, the DW has loads of historical data. For example, marketing people need to be able to reconstruct the amount of business they did with a customer over a period of time last year and compare it with the same period this year. So between denormalization and tons of detailed historical data, DWs are normally BIG! Fortunately they are usually read-only. For Oracle, you want Enterprise Edition with the partitioning option. And study Oracle Materialized Views. In schema, a DW is usually a central fact table and 4-6 dimension tables. Less than 4 dimensions and you don't need a DW. More than 6 and marketing people can't understand the model. Normally the fact table is much larger than the others, but not always.

Re: Exchanging partition takes a lot of times
Thanks for replying. I've seen your post on a similar question on metalink. I've already tested with the constraints enabled novalidate using the default exchange mode (with validation). The exchange is taking 3 seconds. We'll go this way since we're replacing completely the target tables with the staging ones and we're doing all the test on the staging tables before switching. Regards --- Jonathan Lewis [EMAIL PROTECTED] a écrit : See the book - chapter 12, page 250. It's normal behaviour. There is one bizarre SQL run if you do the exchange without validation and another (usually cheaper) if you do it with validation. This relates to checking primary and unique keys, rather than the partitioning constraint. The solution/workaround is to set the constraints to a RELY ENABLE NOVALIDATE. But the last time I checked you still got problems with partitioned tables in involved in parent/child relationships.

RE: disk subsystem performance question
I just started a couple days ago at this client. They're using Hitachi technology in the QA and prod environment with 181G disk. I asked the SA twice and he confirmed the 181 G disk. I'll ask more details to the SA as soon as I know him better. --- Deshpande, Kirti [EMAIL PROTECTED] a écrit : John, I agree with the 18GB drives implementation and pushing for more 'parity groups'. That's what we did. Now, HDS was back to sell more disk and backup soultions to us. I am not sure what we have agreed to purchase. A cache of 10GB for the 400GB database is nothing. I bet you will have tables larger than the cache size. A single FTS on these tables will flush the whole cache... We have 16GB cache (I think I remember that right, and is the max for 7700E), and that is not enough for several servers that the cabinet supports. - Kirti -Original Message- Sent: Wednesday, April 10, 2002 7:08 PM To: Multiple recipients of list ORACLE-L Thanks for all the replies. We are determined to lay out the data as well as we can across the disks we are about to purchase - with the goal of striping across array groups and smaller, faster drives. The real argument for us is 18GB vs. 73GB disk drives and how we can stripe. The Hitachi is configured into groups of 4 physical disks called parity groups and you can choose RAID 5 or RAID 1+0 for that 4 disk set.If you have 73GB drives in a 4-disk RAID 5 configuration you get roughly 219GB of usable space in each parity group (this is what we are being told is the best option for us).This means our heavily concurrently accessed 400GB production database goes on 2 parity groups (2 sets of 4 disks). To me, this sounds like a nightmare waiting to happen and we are trying to stop it.The 18GB drives are less capacity but we can get ourselves spread over more parity groups for better concurrency. We do have about 10GB of cache but it is being shared across the enterprise with various other applications. We as a DBA group are really trying to sell the 18GB RAID 1+0 drive solution especially after reading the groups' experiences - unfortunately we are fighting a lot of marketing hype. If anyone has additional experiences or feedback with Hitachi or EMC they would like to share or comments (agree/disagree) with my thoughts, I'd love to hear them. I'm open for learning!

Nobody's disk subsystem is so fast that no intelligence is required in the layout. This is common vendor blather and one of the most popular myths. I have been hearing it for at least six years - and it still isn't true. Layout still makes a huge difference. RAID levels still make a huge difference. Cache won't solve all your problems (it does help though). I've redone the disk layout on some of the biggest, fastest fully-loaded with cache EMC Syms available that had some don't worry about it layout and seen database throughput go up by as much as 8x.

We have had trouble in the past on the 7700E due to disk contention and layout, i.e. we weren't striped across the array groups very well this caused pretty poor I/O performance.This has been a learning experience for the DBAs and the SAs here for the logical vs. physical aspects of our disks. Anyway, to make a long story short, we are ordering disk for the move to the 9960 and we have 2 choices in disk sizes - 18GB and 73GB, and 2 choices in RAID - 1+0 and 5. I would like to get the smaller, faster 18GB drives in a RAID 1+0 configuration and stripe our data across the array groups as wide as possible. However, I am running into objections from the Hitachi people that their system is s fast we need not worry about such minor
