Healty ratio of index segment size vs table segment size?
Wondering if there is a "rule of thumb", quick'n fast but good enough to be used as an indicator, litmus paper so to speak, of overly indexed table(s)... Can, better yet - should, sheer size comparison of index versus table segments be used as a reliable pointer to problematic table indexing? If it can, what could be considered as average "healthy ratio" above which would be prudent to have a closer look and investigate? Related to the above dilemma, how "expensive" is to monitor index usage, say if script is run against all few hundred indexes on app tables, would the additional load noticeably affect application performance or is it better/safer or may be required to monitor not more than just a few "most suspected" indexes at a time? Thoughts, pointers, opinions - appreciated.

RE: Deleting database
That's right - you would have to drop all schema owners. In my opinion it is simpler and easier task to automate dropping of all owners followed by one full import compared to task of automating database deletions followed by database creations then doing full import in very last step. DOS environment offers weak (better word is miserable) error handling, so unless you resort to non M$ scripting languages to do this task for you I believe you'd be better off to stick with simpler of two approaches. Another reason to try avoiding tearing/re-creating databases lies in the fact that when you create new database on WinXYZ platform, newly created data files are always fragmented at file level (which may not be overly fact important for your test database but it is an ugly site to look at nevertheless).

RE: Deleting database
Run oradim.exe from command line to see how to delete SID. Deleting Oracle service via oradim _will_ remove corresponding registry entries. But why bother removing database, wouldn't dropping schema owner with cascade option followed by full import do the trick?

[ORA-000060: Deadlock detected] Finding BOTH pieces of code that
I realize ORACLE-L could not be the best place to ask this question but (googling/metalink-ing did not help overly)... ORA-60 happens in our own application in the worst of possible places - at the customer's site. It happens intermittently. All I can do is look at the alert log for errors and follow the trail to the extremely verbose trace dumps and wonder. Clearly - I am over my head here as I have very little clue of what am I actually looking at. The question is how to interpret what trace dumps tries to tell (should I be scratching my head with it or is there some kind of magic behind TAR that would save the day)? For instance - what is the meaning of this trace snippet (coming from 8.1.7.x): Deadlock graph: -Blocker(s) -Waiter(s)- Resource Name process session holds waits process session holds waits TM-457a-24 37SX 17 14 SSX TM-4571-17 14 SSX 24 37 SX session 37: DID 0001-0018-0002 session 14: DID 0001-0011-0002 session 14: DID 0001-0011-0002 session 37: DID 0001-0018-0002 Rows waited on: Session 14: no row Session 37: no row On the assumption that the source of the above problem has nothing to do with INITTRANS/PCTFREE combo (as per metalink thread # 247579.999) but the culprit really is the broken app - what would be the 'proper' way to find which two pieces of code deadlocked each other? What comes to my mind ain't a pretty sight - turning on sql tracing on the database level (and suffering worsened performance), then once error happens finding out exact time from alert log, converting it to matching TIC number in 3 sec range (if I understand correctly Oracle will detect and break deadlock after 3 seconds). Once this range is known for 3 sec. window, digging through session traces would reveal what were other sessions doing at the time may be narrowing down the search to few possible sources of contention. Problem with this approach is way too much work to set up then 'dig' through all (tons of) trace files without any real guarantees source of deadlocking would be obvious after all this effort. So the question is - how to help duhveloper(s) by pointing closer to the 'root' of deadlocking?

RE: New to DBA !
On Win2K the easiest way to hack your way back into the database is to log on as local administrator then run orapwd utility to re-create the password file (change working directory to ORACLE_HOME/bin then type orapwd and you'll see the full syntax). New password file should be created in such a way as to be compliant with (or following) Oracle's defaults (be where Oracle expects to find it): ORACLE_HOME\database\PWD.ora If the password file was already there but you forgot the what that password is, rename existing password file to say PWD.ora.old then create the new one: orapwd file=C:\Oracle\Ora92\database\PWD.ora password= Using SQL*Plus: connect sys/@ as sysdba then alter user sys identified by to synchronize sys'es password in data dictionary. After that - the business as usual. Other way to achieve the same (hack back in) would be to fiddle with pfile, sqlnet.ora, and local ORA_DBA group in order to be able to use OS account to log on as SYSDBA and then 'alter user sys...'. But this way is a pain compared to simply 'blowing up' the old password file, creating the new one then re-synch-ing it. Branimir > -Original Message- > From: Rama, Shreekantha (K.)

RE: 100 instances on same server !!!
100 instances is way too much even (especially?) if Win2K is the OS in question. Each instance means another service, and each service means spawning and maintaining multithreaded process... On Windows half of available RAM is taken by default for kernel processes and the other half is all that all other apps can hope to get. In your case with 4 GB of RAM on the system each of 100 instances will be getting 20 generous MB. Not enough by any means, not even considering way too many threads that will befell (say max 4?) CPUs. Having said that, le'mee admit a sin: we run with success (meaning nobody complains about performance) 28 concurrent development instances on powerful (at least it used to be 4 years ago) 4x450 PIII Xeon CPUs with full 1GB of RAM and 21 x 18 GB HDD in few RAID 5 containers (sorry for violating BAARF principles). Although we do run overly large number of instances on a single Windows NT 4 box, in reality most of them are used sparsely, and that's why getting away with it seems to work. Now back to your case - I'd warmly advise to reconsider one box running 100 instances assumption. Whatever you put there - will likely melt. On the other hand if your all 100 of your workstations are same, or form few groups of same hardware, investing in 512 MB of RAM for each of 100 workstations (should be much cheaper comparatively) and in 100 licenses (at approx $30 each) for Norton Ghost Enterprise then: - Slash the PC OS and do fresh install (with SP's and unavoidable patches) then install Oracle and create one local database with application installed and configured, - Take Ghost image of a system, - "Push" the image across all workstations (on condition it hardware is exactly alike) using Norton Multicast Server is a "piece of cake", and literally one "click" job. - See that the same image is used over and over again whenever the next round of training is about to take place. Fiddling with Ghost is NOT a DBA job, but any sysadmin type should pull it with ease (and gratitude, if I may say so ;-).

This requirement is dictated by a prospect of ours, and since they say Win2K and IIS (there is a web part to this job) is a MUST, a must it is indeed. No matter how silly or plain wrong such a choice might be. In my opinion the task in question (database up to a TB in size) accessed via few thousand concurrent sessions that must be up and running in 7x24 mode with exactly 0 down time allowed, fault tolerant and load balanced is clearly way-way above capabilities of today's Windoze platform (but give'em another 20 years or so of slack and may be they'll get there?) I also believe that trying to pull or force such a thing using Windows is comparable to a pitiful task of trying to empty the swimming pool using just a hand and spoon combo, but what do I know... > Let me suggest a little benchmark: 4 clustered, beefed up PC > boxes vs. a single, 16-CPU IBM P690 with the latest "960" CPUs > and AIX 5.2.

Oracle 9.2 RAC on Win2K?
I need help with clearing up one conceptual issue:
My understanding is that with Oracle RAC one set of physical database
files "sitting" in the "middle" - shared storage are being accessed by
multiple Oracle instances running on multiple physical servers (nodes).
All instances "attacking" (sharing) the very same set of data files at
the same time. Right or wrong?
Provided the answer on the above question happens to be "yes" - I'd like
to ask List Folks how feasible is to assemble and successfully (smoothly?)
run 0.5-1 TB database, use Oracle RAC and high performance shared storage
(say SAN) served ("pumped") by a number of Windows 2K servers?
The "number" of Win2K servers I have on mind is at least 4 "beefy" (as
beefy as it gets in Windows wrld) Win2K "boxes" each running Win2K AS
with lots of RAM and at least 4 CPUs, with perspective of adding more
later.
It would be nice (for me) to know if new nodes can be added to the
cluster at any later time to improve performance (in order to deal
with increase in usage or to accomodate growth over period of time).
It would be very nice to know if number of nodes is or is not limited
(otherwise than by raw I/O capabilities of the shared storage).
Has anyone seen/run/stumbled over similar beast, if so - does it "fly"
or it "stinks"?
Thanks (for any help, hints, links, etc.),
Branimir
P.S.
I've looked at number of metalink articles and found none yet to
"scratch" this specific "itch" of mine.
Oracle RAC on Win2K is for some bizarre reason REQUIREMENT.

Out of sheer (sick?) curiosity - why wouldn't you want that? What happens if "manual-start-up-preferring" DBA goes on 2 week vacation and server gets rebooted as a result of prolonged power failure? Consequence will be - the database will not re-open automatically as it was specifically "told" not to do so... Having seen results (utter panic striking one of our customers) I always wondered what could have possibly been the motive or rationalization for setting things up this way in the first place.

RE: ??? Linux/Oracle 8.1.7 2GB file size limit ???
I'd say file size limit/autoextend feature has been Oracle's dirty little secret for quite a while. For a very long period of time there was similar 4GB 'magic' barrier on Windows, that was allegedly fixed. Workaround for the problem was to create datafile 1 MB larger than the 'magic' number, and ether resize it using this trick or add another datafile to tablespace when the time comes (whenever MagicNumber or N x MagicNumber is close). Despite rumours (of having fixed autoextend feature on Windows) I recently witnessed failed imports into Oracle 9.2.0.1.0 caused by too small tablespaces that just wouldn't autoextend. Interestingly, import died "beautifully" cuz silently in the middle of job without _any_ errors, traces etc. Just gone. There is also interesting myth here at the place where I work that systems tablespace autoextend feature ain't to be trusted as "it is known" to have caused intermittent data dictionary corruptions while code recompilation takes place under space "crunch" conditions... On slightly cynical side note: autoextend that doesn't - maps nicely into job safety ;-) Branimir > -Original Message- > From: Orr, Steve [mailto:[EMAIL PROTECTED] > Sent: June 4, 2003 11:40 AM > To: Multiple recipients of list ORACLE-L > Subject: ???

RE: nt script
Title: RE: nt script
Do yourself a
favour - resist temptation of even considering DOS batch "language" (as it
is nothing more than a horrid pile of I-won't-say-what;-)
Better
choice is WSH and VBScript or JScript. Windows Scripting Host comes with
every IE - therefore every Windows machine. Should you go this way keep on mind
that you will be painting yourself (using M$ proprietary paints) in corner with
your own hands.
It makes the most
sense to choose cross platform scripting language then use it wherever you go.
Down side - you'd have to ensure this particular scripting environment is
installed on all platforms/systems you support.
Python and Perl
are two mature beasts that pack (more than) enough power, and yet are
platform agnostic. Worth learning? You bet.

PMTo: Multiple recipients of list ORACLE-LSubject: RE:
nt script
Can anyone recommend a book / website on the DOS batch file
language? I usually try to install cygwin and write shell scripts but some of
our database servers don't have cygwin.
For example, I have no idea what this statement does:
FOR /F "TOKENS=1,2*" %%A IN ('DATE/T') DO SET DATE=%%B
and when I tried it I received an error H:\>FOR /F "TOKENS=1,2*" %%A IN ('DATE/T') DO SET DATE=%%B
%%A was unexpected at this time.
