RE: UNION ALL Query: Riddle
I have the same problem like you Rajesh, the query also gives different rowcount each time executed eventhough there's no one updating base tables, in my opinion it's because of the sorting operation (your group by clause). In my case after I remove some group functions, the result goes well. Also I reduce the use of order by clause where it's not needed. I still haven't found the exact solution to this problem. But just now I've tried to decrease the sort area size parameter value (I think I oversize it), and run the query again, the result goes stable with the problematic query but it runs slower. I haven't tried intensively, I try to do that tomorrow. Meanwhile if, there's any of the Gurus can give us clearer explanation, please do so... Thank you all in advance.

Re: [Q] wait time on stat
Mladen,
Here I will humbly disagree with you. It is not fault of Windows but the
person who created the database and defined tiny size log files while
creation. If he used custom database option he can define whatever size he
wants. These options are same for both Windows and Unix.

Defaulty Windows installation usually creates log files of 20M. The person
who posted the problem explicitely mentioned Windows platform.
Size of 20M is so small that the database will start to checkpoint
like crazy when you start using it for real. The number that I gave
is my rule of thumb. It's not to big to frighten the boss (alltogether
just a gig or two) and it's big enough to solve checkpointing problem.
This rule of thumb number is derived from experience. Yes, of course,
I am guessing. There is not enough information to investigate the
problem. I believe that he was asking us to guess. I did.

How did you determine the size of the logs?
Or are you just guessing that they are significantly
less than 250m?
Could just be a very busy database that needs redo
and controlfile on faster disk.

RE: measuring TPM
And these would be CPM (commits per minute) and RPM (rollbacks per minute). If you really want a transaction, you have to code it yourself, otherwise all you can get is CPM and RPM. If your transactions_per_minute ( or commits_per_minute) is low use this handy script to bump it up. create table my_dual as select * from dual / begin for i in 1 .. 1000 loop insert into my_dual values(i); commit; delete from my_dual; commit; end loop; end; / add salt and pepper to taste, serve with nice red wine, enjoy.

I know of the following methods: 1) Turn on auditing, count all transactions from dba_audit_trail table within a day and divide by the number of minutes in 9 hours. That will give you an average TPM number during the working hours. The problem is that auditing will impact the transaction rate. 2) Pick a single user, a chosen average Joe (or Josephine, to to avoid accusations for gender bias), create a logon trigger which will record user commits from v$sesstat and that will be the number of transactions. Divide by the number of minutes and multiply by the number of users on your system. The problem with this method is that it is usually very hard to pick up an average overall user of the system, so the whole thing is performed by department. 3) Count user commits in v$sysstat, which will count them system-wide. Divide by period. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Jamadagni, Rajendra 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).

Then, I do: alter system set use_stored_outlines = true ALTER SESSION SET CREATE_STORED_OUTLINES=true;select * from edi_monitor_vw;ALTER SESSION SET CREATE_STORED_OUTLINES=false; I can see the outline in DBA_OUTLINES and also in outln.ol$ If I open another session and run the query, it is NOT using the correct explain plan. If I 'alter system set use_stored_outlines = false;' then the query uses the correct plan. I also noticed that outline_category in v$sql is NULL. Does this mean that they outline is not being used?

There is no simple way, What is important for you ... value of the element or the

Tell us again what is the problem? is it that you have too many array elements? where
does the time goes? it should be in the execution of the function .. not in navigating
from one element to next.

Sorry I did not make it clear that the number I used here (1, 9, 15,99) are
just examples, the actual element index is a varible and they are not
continuous. Yes, refTbl can be defined into a package. I guess what I am
asking is if there is a way in pl/sql to do something like
-- FORALL array element indexes (they are non-continuous)
call a package function (parameter: element index)
-- end for
without looping the array.
-- orginal code:
declare
type numTbl is table of number index by binary_integer;
refTblnumTbl;
i number;
str varchar2(30);
begin
refTbl (1) := 1;
refTbl (9) := 1;
refTbl(15) := 1;
refTbl(99) := 1;
i := refTbl.first;
while i is not null loop

Re: [Q] wait time /lob def
There is a note in one of the manuals about nologging lobs (or nocache lob, I forget which) that points out that the unrecoverable SCN for file that holds the LOB has to be updated in the control file whenever the LOB is updated. If you actually have a performance problem because of this - i.e. if lots of people/processes are running slowly because they are waiting on control file writes - then you might want to make the LOB cache/loggong. But control file writes are not inherently a bad thing to be blocked. Of course, if the LOBs are quite large, then the time taken to write the LOB may be far greater than the time taken to update the controlfile - which would make any concerns about the controlfile update irrelevant. So there is no 'obvious' correct answer to your question, without examing your current activity. The note (which I think Steve Adams' also has on his website) mentions an event that can be set to stop the controlfile update when the LOB is updated. This may not be a good idea, though, as it may affect some aspects of recoverability. If you do make the LOB 'cached', then remember that all reads and writes go through the db_block_buffer, which could affect all the other I/O activity adversely, so you might want to consider putting the LOBs into a tablespace with a non-standard block size so that the LOB activity doesn't affect the rest of the cache. (You do also have the option in more recent versions of refining the caching properties so the LOB can be readcache only, writecache only or read/write cache or nocache, I believe).

Re: [Q] wait time /lob def
That is an interesting use of an alternate block size Jonathan. Jonathan Lewis [EMAIL PROTECTED] Sent by: [EMAIL PROTECTED] 01/29/2004 09:59 AM Please respond to ORACLE-L To:Multiple recipients of list ORACLE-L [EMAIL PROTECTED] cc: Subject:Re: [Q] wait time /lob def There is a note in one of the manuals about nologging lobs (or nocache lob, I forget which) that points out that the unrecoverable SCN for file that holds the LOB has to be updated in the control file whenever the LOB is updated. If you actually have a performance problem because of this - i.e. if lots of people/processes are running slowly because they are waiting on control file writes - then you might want to make the LOB cache/loggong. But control file writes are not inherently a bad thing to be blocked. Of course, if the LOBs are quite large, then the time taken to write the LOB may be far greater than the time taken to update the controlfile - which would make any concerns about the controlfile update irrelevant. So there is no 'obvious' correct answer to your question, without examing your current activity. The note (which I think Steve Adams' also has on his website) mentions an event that can be set to stop the controlfile update when the LOB is updated. This may not be a good idea, though, as it may affect some aspects of recoverability. If you do make the LOB 'cached', then remember that all reads and writes go through the db_block_buffer, which could affect all the other I/O activity adversely, so you might want to consider putting the LOBs into a tablespace with a non-standard block size so that the LOB activity doesn't affect the rest of the cache. (You do also have the option in more recent versions of refining the caching properties so the LOB can be readcache only, writecache only or read/write cache or nocache, I believe).

Jonathan / Tanel:
I, however, AM having this problem. Didn't know where
to look till I saw this message. (I love this list!)
So do I ;)
I've yet to capture the sid (and therefore track back
to the table) where the 'direct path write' occurs.
Definitions for the tables were supplied by the
vendor. When I look at at the lobs, the definitions
are mixed. Most are nocache, logging yes. some are
no/no
I don't see much on metalink about this -- just a
couple of generic articles on lob storage.
If you are up to attending RMOUG Training days in few weeks, then I'll be
speaking about LOB performance tuning there, you're most welcome ;)
Should I change the lobs to cache/logging across the
board?
Well, if you set all your LOBs to CACHE (cached LOBs are always logged),
then you'll be generating more redo for current nocache nologging LOBs as
well. Also, your buffer cache gets hit, especially if your LOBs are big.
One possibility is setting event 10359 at level 1 to what Jonathan also
referred, then your direct writes won't cause controlfile updates anymore.
But when you have set this event, you can't rely on UNRECOVERABLE_CHANGE# in
your V$DATAFILE anymore, for determining whether a datafile should be backed
up due nologging operations in it.
If you should ever need to restore a file containing NOLOGGING NOCACHE LOBs,
then any inconsistent blocks will be marked corrupt (block sqn=0xFF) since
there was no redo information logged for them. In that case you have update
the corrupt LOBs to nulls for example to reclaim the space in LOB segment.
Note that having few corrupt LOB items in a LOB segment won't affect other,
healthy LOB items, you just have to have some kind of error handling
mechanism implemented when you hit a corrupt item.
Note that updates to LOB indexes are always cached and logged, despite the
NOLOGGING setting.
Tanel.
Thanks for any insight.

Re: [Q] wait time /lob def
Thanks, Tanel.
Yes, I'll be at RMOUG.
I'll be in the front row for your presentation.
Again, thanks for the info.

Jonathan / Tanel:
I, however, AM having this problem. Didn't know
where
to look till I saw this message. (I love this
list!)
So do I ;)
I've yet to capture the sid (and therefore track
back
to the table) where the 'direct path write'
occurs.
Definitions for the tables were supplied by the
vendor. When I look at at the lobs, the
definitions
are mixed. Most are nocache, logging yes. some
are
no/no
I don't see much on metalink about this -- just a
couple of generic articles on lob storage.
If you are up to attending RMOUG Training days in
few weeks, then I'll be
speaking about LOB performance tuning there, you're
most welcome ;)
Should I change the lobs to cache/logging across
the
board?
Well, if you set all your LOBs to CACHE (cached LOBs
are always logged),
then you'll be generating more redo for current
nocache nologging LOBs as
well. Also, your buffer cache gets hit, especially
if your LOBs are big.
One possibility is setting event 10359 at level 1 to
what Jonathan also
referred, then your direct writes won't cause
controlfile updates anymore.
But when you have set this event, you can't rely on
UNRECOVERABLE_CHANGE# in
your V$DATAFILE anymore, for determining whether a
datafile should be backed
up due nologging operations in it.
If you should ever need to restore a file containing
NOLOGGING NOCACHE LOBs,
then any inconsistent blocks will be marked
corrupt (block sqn=0xFF) since
there was no redo information logged for them. In
that case you have update
the corrupt LOBs to nulls for example to reclaim the
space in LOB segment.
Note that having few corrupt LOB items in a LOB
segment won't affect other,
healthy LOB items, you just have to have some kind
of error handling
mechanism implemented when you hit a corrupt item.
Note that updates to LOB indexes are always cached
and logged, despite the
NOLOGGING setting.
Tanel.
Thanks for any insight.

Hi!
Do you have any LOBs defined with
the nocache nologging attribute ?
This was what I initially thought would be the
problem, but then I thought,
in case of nocache lobs you should see direct
path
writes (lob) a lot...
Tanel.
