Re: 10g new features question for beta testers
It's the Best of Breed versus One Vendor debate, and there are pros and cons galore. The perfect scenario, of course, is when they combine, so one vendor delivers the best of everything. That's what we have with Microsoft, isn't it? ;-) : Office stuff, OS, Database, ERP, CRM, video player, what have you... Then on the Support side of things, it's indeed good to be able to call One Vendor Only... if that vendor is good at Support. If he isn't, you might be better off if you have more than one option for calling. Mogens Pete Sharman wrote: Just a couple of comments on this which hopefully won't go down the Marketing track too far. :) 1. I'm pretty sure Steve Adams agrees with you, since he co-presented on ASM at OracleWorld in San Fran. Not sure if he monitors this group actively or not, but I believe the presentation he did is loaded with all the other OracleWorld 2003 presentations so you can see what he said. 2. One point which makes a lot of sense to me, and it happens in a variety of places in 10g such as ASM and the RAC clusterware. If you have one vendor to raise an issue with (not that you'd need to do that with Oracle of course!), it's a lot easier to get an answer without the finger pointing that can go on between vendors. Take the clusterware example - if you run into a problem running RAC on Sun with the Sun Cluster technology and Veritas owning the disk side, who you gonna call? GhostBusters, maybe! But if you're running RAC on Sun with Oracle's clusterware and ASM, it's a lot easier to determine who to call. Pete Controlling developers is like herding cats. Kevin Loney, Oracle DBA Handbook Oh no, it's not. It's much harder than that! Bruce Pihlamae, long-term Oracle DBA -Original Message- Connor McDonald Sent: Saturday, December 20, 2003 2:34 AM To: Multiple recipients of list ORACLE-L As with anything I suppose, if a single vendor can be in control of more of the stack between application and physical server structure then there is a greater opportunity for benefits. For example, ASM offers the ability to add disks to a stripe without needing to redistribute(reload) the entire stripeset. A (bug-free) ASM product looks very very impressive to me. Time will tell how close Oracle are to achieving it. hth connor --- [EMAIL PROTECTED] wrote: no ASMs are considerably different. Its supposed to manage everything. You dont give it a file, you give it entire disks and oracle does everything. Sets up files, manages, I/O, everything. you only look at the tablespace level. you dont even install any software on it.

Oracle 9i has Oracle Managed Files where you give it a directory and then just build tablespaces. The database picks the filenames for you. Now mind you it does work, but I'll be damned if I use it in anything other than a development environment.

I know atleast one other person from the list was there. Since Oracle is releasing details and its going to be released(in theory) in the next 2 weeks, I was wondering if you guys could talk about it. 1. does ASMs work as well as Oracle claims? I always wonder about first generation features... takes most software vendors a couple of generations to get it right(takes any project Im on just as long). This is a radical departure. for those of you who dont know. Oracle claims that they will manage your disks for you. All you do is give Oracle some Raw Disks and Oracle will set up, and handle all your datafiles. All you do is look at logical tablespaces. It will also handle I/O balancing. How well does this work? Anyone test it with a SAN? 2. RAC Load Balancing. Oracle claims that you only need Oracle software from now on. They also claim that you can load balance multiple applications. Lets say you have One application that runs batch loads over night and a transactional application during the day oracle will automatically steal resources from the other when its not busy... anyone test this? 3. Flashback database. Kyte was the presenter and he said that you can keep massive undo areas, so that if you have a failure or delete data you shouldnt have you can have oracle automatically write the DML necessary to bring it
Re: Hit Ratio
Ah yes, you could introduce heuristically (spelling?!) skewed hit ratios. As Dave Ensor explained at UKOUG, the word heuristic in Oracle's optimizer code can be translated directly into constant. So add a number here or there until it fits.

Hello list, I am using 9.2.0.1.0 enterprise edition on windows. Earlier when I use to specify nls_lang=French_France.US7ASCII in 9i release 1 I would get the following messages in French c: sqlplus Entrez le nom utilisateur : But now when I specify nls_lang=French_France.US7ASCII , sqlplus sticks to english c: sqlplus Enter user-name: Any ideas ? I tried out the following but to no avail : 1. I specified ora_nls33 to point to D:\OracleXP\Ora92\ocommon\nls\ADMIN\DATA where D:\OracleXP\Ora92\ is my %oracle_home% 2. I set nls_lang=French_France.US7ASCII , log in as a user, checked NLS_SESSION_PARAMETERS. It shows that NLS_LANGUAGE is FRENCH and NLS_TERRITORY is FRANCE. When I select from a column containing dates , the months are in French. sysdate also gives the month in french 3. Same behaviour with nls_lang=French_France.WE8MSWIN1252 and nls_lang=nls_lang=French_France.UTF8 (although this is an incorrect specification since there are no utf8 windows clients ) 4. Similarly when I specify nls_lang=ENGLISH_INDIA.WE8MSWIN1252 my queries pick up the correct local currency symbol. and nls_language and nls_territory values in nls_session_parameters are correct. 5.
