Incremental Checkpoint
Dear Guru's Have a question. Does a incremental checkpoint update the datafile header with the SCN?. My understanding is that it doesn't update the datafile header but only updates the controlfile with the SCN and the datafile header is updated only during a full checkpoint Is my understanding correct?

Defragmenting a RAID 5 volume?
Hello people, We recently experienced a hang in our database server, WIN2k Advanced server with raid 5 for Oracle 817 database files. Examining the perf logs showed that Event 2022 caused the hang: Event ID: 2022 Source: Srv Description: Server was unable to find a free connection 144 times in the last 60 seconds. After I examined the alert log, I saw an object trying to extend but fails because the DBF ran out of space. This happened on the time/instance that the server started to stop responding. The DBF is supposed to extend because it is configured to AUTOEXTEND. The available disk space isn't also supposed to constrain the DBF's extension of 64MB, free space of 9+ GB could still accomodate this, obviously. More importantly, this can happen without crashing the server. According to Microsoft's website (http://support.microsoft.com/default.aspx?scid=kb;en-us;245077), possible resolutions are to defragment the disk or allocate more disk space. Disk space is not much of an issue because the volume still has 9+ GB. My question is, can a RAID 5 volume be defragmented? Is it sane, technically? The volume is 130GB in size... Best regards, Rhojel
Re: Unusable partition index -- working funny
It's probably the case that the trigger fires the first time - but at parse/optimise time Oracle had already determined the sequence of actions needed to execute the statement based on the then session state, so that sequence is played out, irrespective of the fact that you changed the session state in the middle of the sequence. By analogy, consider an update to an updatable join view which defaults to using a hash join. If you create a before row update trigger to disable hash joins, would you expect Oracle to not do a hash join the first time the statement executes ?

Re: FW: Disk capacity planning
Mladen, I agree you can measure how many IOs are being done and how many a disk sub- system, such as those provided by EMC, can perform and still give good performance. What I meant is that it is hard and some would say impossible to estimate how many IOs per sec a new application will do. A combination of paper calculations, testing, experience and looking at comparable systems will help to provide a good estimate. Cheers, Chris Quoting Mladen Gogala [EMAIL PROTECTED]: Oh, but it is done, you only need to ask. EMC routinely measures how many I/Os per second can they perform and they even have tools to measure it. Speaking of monitoring I/O, there used to be an old OS, which is mostly dead today and it used to have command monitor io/item=queue which would show length of the I/O queues per device, which was extremely useful, because you could quickly find out which devices are hot and which are not. On 2004.01.20 04:19, [EMAIL PROTECTED] wrote: Cary, Good answer. The problem is most people concentrate on bytes because it's relatively easy and everyone understands it.

Counting bytes is important too, but what many people find is that the byte-counting exercise will result in the sub-verdict of needing far fewer disk drives than you'll really, truly need. The way I'd recommend structuring your project is to evaluate the following: - How many bytes will you need to store your data? How many disks is that? Call the answer B. - How many disks will you need to meet your IOps requirements? Call the answer P. - How many disks will you need to meet your availability requirements? Call the answer A. - (Consider other attributes as necessary, like perhaps I/O throughput requirements.) Roughly speaking, the number of disks you'll need to buy is max(B, P, A, .). It's more complicated than that because you'll need to segment your total drive set into sensibly-sized arrays, you'll be able to buy some disks now then some later, and so on, but this is the general gist. The important thing is to have enough hardware to meet *all* of the constraints your business will place upon your system.

Re: Has anyone done any scalability work on dbms_lock?
As in: does it present an inherent or hidden performance problem when a lot of sessions try to lock/release the same lock? Will serialize perfectly! Or how many lock/release per second. Or some other idea of how efficient it is? Depends on the work done between acquiring the lock and releasing it. Need to use it in a design, but not sure of any potential performance hits or scalability issues. Any ideas? When sessions acquire the same lock (as asked), only one session can do the work in a given moment. So, it doesn't scale.

Re: Has anyone done any scalability work on dbms_lock?
On a light-weight test on 8.1.7.4 at 700MHz on W2000 - About 15,000 request/release per second if you are using an ID About 8,000 request/release per second if you are using a pre-allocated lock handle About 800 request/release per second if you have to allocate_unique on every request. Bear in mind that each request or release will hit the enqueue latch a couple of times, so you could get contention for the latch in the two high-speed options. (Forget the low-speed option, allocate_unique does a commit in mid-stream, which you might be able to hide with a recursive transaction - but the overheads are extreme). Bottom line - for high-speed OLTP type of work, I don't think you will get away with more than a dozen request/release cycles per transaction.

Re: Has anyone done any scalability work on dbms_lock?
- Original Message - Or how many lock/release per second. Or some other idea of how efficient it is? Depends on the work done between acquiring the lock and releasing it. Not really. I'm asking how many lock/releases can be done before the thing starts putting a serious load on the system. And if the load it imposes is linear. When sessions acquire the same lock (as asked), only one session can do the work in a given moment. So, it doesn't scale. There will be overhead, but that also is relative to the duration of the work done while the lock is held. So, the overhead is MOL linear? Ie, if the amount of work is very small and the number of requests is very high, nothing is gonna suddenly go South? Maybe AQ can help, by doing the work asynchronously in the background and so lift the serialization from the primary proces(ses)? The work is very small indeed. No need to background anything.

On 01/21/2004 03:04:26 AM, [EMAIL PROTECTED] wrote: GB. My question is, can a RAID 5 volume be defragmented? Is it sane, technically? The volume is 130GB in size... You are defragmenting a file system, not a volume. Block based file systems cannot be defragmented, only extent-based file systems can. Block based file systems like UFS or SYSV-1K FS do not have extents, which means that the word fragmentation doesn't make sense. You have superblock, inodes and data blocks. You don't have extents. AFAIK NTS is an extent-based file system and it can be defragmented. It is questionable, however, what will you gain by defragmenting. If your files have n extents, their extent maps are cached in memory and need not to be re-read each time you access files. Hopefully, you're not using an NT system for DW, which means that your I/O pattern consists of random reads/writes, few blocks at a time. Fragmentation hurts you when you are doing frequent multiblock reads which are split into several I/O requests instead of being satisfied by a single large one. As defragmenter moves file extents around, database cannot be accessed, which essentially means that you must shut down the instance or it will hang. I don't know how much will you gain, but yes, you can defragment 130GB file system, even if it's on a Rabid Array of Inefficient Disks. As they say, size doesn't matter, it's the magic in the disk. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Mladen Gogala INET: [EMAIL PROTECTED] Fat City Network Services-- 858-538-5051 http://www.fatcity.com San Diego, California-- Mailing list and web hosting services - To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).

Re: Parallel Query determined by?
I could not find an Oracle wait event named 'Parellel Sync Wait' (in v$event_name view in 7.3.4, 8.1.7.4, 9.2.0.4). Precise may be calling something else a 'Parallel Sync Wait', or is smart enough to figure this out when it seems Oracle isn't instrumented for this particular wait(?). Just pondering... Does Presice on-line help have any mention of this wait? Have you contacted Precise Tech Support? - Kirti --- [EMAIL PROTECTED] wrote: No other replies yet, so here goes. First of all, what does it really mean when you say: users are complaining that Precise is showing a whole lot of time in Parallel Sync Wait. Are these end users, or developers?

Folks --
I have good news and bad news. ;-) First the good news:
Several people had mentioned that they've sent messages to some lists but
have not seen the posts arrive back to them. These messages DID appear in
the archives though. This started roughly 12-Jan-2004. I had previously
researched this issue but could find no reason for it happening, nor a
solution. Up until today, that is.
The cuplrit was one of my load balancers for mailing list traffic. It was
handling traffic correctly on some of the machines, but squirreling away
messages sent to one specific server. I'd estimate about 1/8th of the
messages sent to mailing lists since 12-Jan-2004 were not redistributed
properly. I have since found and fixed the problem, so this shouldn't
happen in the future. I suspect I was only able to re-send a portion of
the missing messages, so my apologies for anyone who posted a message that
didn't make it to a list. Also, my apologies to everyone who has to deal
with the increased traffic of the old messages, plus current messages,
plus the inevitable onslaught of re-posts that will occur in the next few
days. Please be patient with each other.
So the good news was: problem found, problem fixed, some catch up done,
shouldn't happen again.
The bad news is that this morning (roughly 7am PST), a construction crew
near Fat City cut through a section of telecom cable that was critical for
our connection to the net. They've been working feverishly on it all day,
but Fat City was off the net most of the day. Until about 3pm PST. I
believe things are about back to normal right now, but there's always a
ramp-up time to truly get back to normal. My apologies to anyone who was
affected by our downtime.
If you have any questions or concerns about anything, please let me know.
Thanks,

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?

RE: 9iAS Calender Servlet
Calendar servlet sounds pretty generic. What more specifically do you want your servlet to do? If you are writing a PL/SQL Web app with mod_plsql, you might want to look into the OWA_UTIL procedure that takes a query and writes a calendar page in HTML. The query includes columns for the dates to be shown on the calendar, text to be shown in the cell for each date, and optionally an URL to which the text will be a link. -Original Message- Sent: Wednesday, January 21, 2004 7:45 AM To: Multiple recipients of list ORACLE-L Does anybody by chance have any examples for creating a calender servlet for 9iAS?

Where is this limit set? Is it possible to change the setting?

Re: V$system_event
The result depends on the number of sessions. If you have
session A waiting for a 'enqueue lock' for 10 minutes and session
B waiting for the same lock as session A for another 10 minutes,
then the recorded time is 20 minutes, despite the fact that sessions
are waiting concurrently. If you have, say, 500 concurrent sessions,
the numbers will be exorbitant.
V$SYSTEM_EVENT is a summary table and not very useful at that. Your
query gives you the most important thing:the percentages. The
percentages tell you that I/O related events ('scattered read' for
table scans and 'sequential read' for index scans) are not taking too
much time, relative to the other events. In other words, you found
another way of calculating BHCR and have significantly advanced
something that one of the recent books calls method C.

Re: FW: Disk capacity planning
When I worked for Oxford, there was a way to force the application to either perform or die. The OLTP database was enforcing profiles and there was limit of 1500 logical reads per call, because it was estimated that our typical OLTP application never performs more then that. If application was unable to achieve that performance, it wasn't allowed to the production OLTP system. That way, the performance could be guaranteed.

Re: pga_aggregate_target and a memory leak
Kirti, you're back! Must have finished the book. :) Re the PGA problems, what was the value for 'over allocation count' in v$pgastat? Did you try increasing P_A_T to a larger number? Oracle is supposed to grab the memory it needs, if available, regardless of the P_A_T setting. Also, did your system go in to excessive paging or swapping? I've been curious as to what the effects would be of having P_A_T too low. Oracle is supposed to grab whatever memory it needs. I'm assuming at this point that doing so involves a different code path as it needs to alloc the memory. Don't know what the cost of that is, haven't tried to test it.

RE: after the discussion yesterday on db2/mysql/postgresql....
Thought PostGreSql smelled a lot like DB2. And although I agree with their definitions on the surface they miss a lot of the underlying capability in Oracle. Sure, one database per instance, but you can them map multiple applications/schema's into that instance. Makes for a lot less fun when one application needs data from another that's in the same instance.

You can also trap the Oracle errors for password expiration or locked account and display a more understandable message instead. This is the way I did it. Also, create a function or procedure that checks the EXPIRY_DATE and ACCOUNT_STATUS in the all_users or dba_users table to determine when the password will expire or if it has already.

If the account is expired the login screen resets and prompts for user id and password over and over. I have opened a TAR wit Oracle support, but they don't have an answer to that effect.

Add a check in your connection section that will propagate any exception encountered. You can also trap the Oracle errors for password expiration or locked account and display a more understandable message instead. This is the way I did it. Also, create a function or procedure that checks the EXPIRY_DATE and ACCOUNT_STATUS in the all_users or dba_users table to determine when the password will expire or if it has already. The function/procedure then can raise an exception if the account is within the grace period or locked. RWB Reginald W.

I've tried the profile by setting up a test user and expiring the account. If I go to sqlplus and log in with the expired user account sqlplus prompts me for a new password. I don't have a problem with that, but you know how users are, they wouldn't figure out why. And management wants users to receive a message telling them why they have to change their passwords without going through the Help Desk. My guess is that a pl/sql package has to be written so users get their password check at login time and receive messages such as the number of days they have before the password expires, or that the password is actually expired.

Re: Re: pga_aggregate_target and a memory leak
I think it depends on your applications. In DSS type environments we are still stuggling to figure out if P_A_T is helping or not. Initial tests are not in P_A_T's favor. But in another Application, that is 80% OLTP, P_A_T was the only choice to avoid swapping. This 9.2.0.3 database had the S_A_S set to 2MB (S_A_R_S = 1MB)at the instance level. It has over 600 persistent users. No MTS in use. - Kirti --- [EMAIL PROTECTED] wrote: kirti-- would you recommend avoiding pga_aggregate_target for now?

Thanks. Found some slack time from routine DBA work! Must have finished the book. :) Not yet.. Its tough.. Re the PGA problems, what was the value for 'over allocation count' in v$pgastat? Actually, I never bothered to look at v$pgastat. Should have.. and will, when we do some more testing next week.. Did you try increasing P_A_T to a larger number? Yes... Oracle is supposed to grab the memory it needs, if available, regardless of the P_A_T setting. Also, did your system go in to excessive paging or swapping? Yes, it did with a large P_A_T. I've been curious as to what the effects would be of having P_A_T too low. I saw more disk sorts.. As time permits, I will play with event 10032, 10033 trace for sorts to see what's going on.. Oracle is supposed to grab whatever memory it needs. I'm assuming at this point that doing so involves a different code path as it needs to alloc the memory. Don't know what the cost of that is, haven't tried to test it. It seems likely that the OS was out of memory, regardless of the P_A_T value. No. The system has 4 GB of physical memory.

I have very recently seen a case (Solaris + 9.2 but I cant't tell you exactly which patch level - probably the most recent) where two (by the way atrocious) queries generated by a DSS tool were responding very differently - and in a way that differences in the queries couldn't explain. From an Oracle standpoint, stats were roughly the same. Tracing proved that we were waiting for CPU, and truss that a call to mmap() was the culprit. Why, no idea. We first switched it (pga_thing) off, no more slow call to mmap(). However, it was still slow because we hadn't checked sort_area_size which was ridiculously small. We set sort_area_size to 10M, still with pga_aggregate_target unset, and once again the same very slow calls to mmap(). Memory misalignment? Anything else?
