Optimizer_index_cost_adj
Hi,
Is there any documentation link by which i may know the formula for calculation of optimizer_index_cost_adj parameter in oracle version 10.2.0.1 for windows 32 bit machine. I knows that the value of this parameter influence index access, so i want to know how do i calculate the proper value for optimizer_index_cost_adj.
Thank you.
You keep asking for a formula. There is no "formula".
Pre-10g, DBAs would either
a. ask another DBA "hey what value do you use" and then the other DBA says "I set it at 25" , so the first DBA says "OK, I will set it at 25"
and/or
b. set it at different values and see the impact on execution plans and actual query execution time -- ie "performance".
Application vendors would say "we have tested different values with our application and highly recommend that you set it at 25" (or "... set it at 10") and so on.
All such methods would ignore the fact that different hardware combinations, under varying loads, perform differently.
Asking for a formula for this is like asking for a formula for the SGA size or for the number of disks or number of CPUs. The answer is : "it depends".
You may finally find someone who gives you a formula. Then you turn around it and use it on 4 different servers with different hardware and different database loads and find that there is no "one size fits all".
Here's a secret :
If you don't collect system statistics, the Optimizer will use certain hardcoded values for "single block" and "multiblock" read times -- and these values may be different for different platforms. Unfortunately, they do not account for differences in Storage subsystem performance and differences in database load (a query intensive application is very different from a write intensive application).

Setting parameters optimizer_index_caching and OPTIMIZER_INDEX_COST_ADJ
Hi Guys!!
I have to change the OPTIMIZER_INDEX_COST_ADJ and optimizer_index_caching parameters at the system level . is there any way to do that apart from shutting down the database. Version 9.2.0.8 , OS HP-UX . and please give me the procedure for that
Thanks in advance
Vickyvivky,
I believe both the parameters are dynamic and can be changed without bouncing the db.
I have done it here on my system and it works fine,

Performance problem in OLAP DB by using optimizer_index_cost_adj=1
Hi,
I have Oracle 11gR2 as my DB and Siebel 8.1 Application
I would like to ask everyone about the significance of below two parameters:
1> optimizer_index_cost_adj=1
2> optimizer_index_caching=0
I'm facing performance issue while extracting data from my OLTP DB to OLAP DB. Below I have described it much briefly for your persual
I had noted that the explain plans to extract the data from OLTP are very bad to extract lots of OLTP data.
For example, the explain plan for one of our transaction called "extract person data" is mostly doing nested loops instead of hash joins. I checked some OLTP parameter and I noted one important Db parameter “optimizer_index_cost_adj “ has the current value 1.This leads to the nested loops as the DB is not acting cost based Since, Oracle recommends this paramter value to 1 for better performance of Siebel application.
Whereas, If I change the above paramters to below values
optimizer_index_cost_adj=25;
optimizer_index_caching=75;
and I reused this parameter as to create explain plans for the specific long running queries and they changed as expected.
Now, my question is if Oracle recommends 1> optimizer_index_cost_adj=1 and 2> optimizer_index_caching=0 then why the cost for many queries increase enormously which in turn leads to bad performance during extraction of dat from OLTP system to OLAP system?
Request you to please comment and suggest me how to proceed
Thanks,
AnilGoing from 10.2.x to 11.2.0.3 I have often noticed two points:
First, you must re-gather system statistics. If you run
select * from sys.aux_stats$;
what do you get? Have they ever been gathered? I suspect the 11.x makes more use of them than earlier releases.
Secondly, the default for serialdirect_read is now auto, in 10g it was (I think) false. This can have a big effect on pushing the optimizer away from indexes. -
Whether to use optimizer_index_cost_adj?? Please advise...
I am troubleshooting some issues we are having with a customer db in which some queries are performing poorly. I have checked (and run) statistics using DBMS_STATS.gather_schema_stats. I have been reviewing parameters and haven't come across anything unusual.
Currently the parameter optimizer_index_cost_adj is set to 100, the default. I have been experimenting with setting this to different values and have found that the lower I set the the better the plan. Setting it to a value of 1 actually seemed to be the best.
But I have been reading many docs where it recommended to set it to a higher value, if at all. Can anyone provide some insight as to their experiences with this parameter? I am hesitant to set this without knowing how it might effect other queries.
Your thoughts are appreciated. Thanks. TylerHi,
I agree with the other posters. If you have the time, try to adjust your schema stats BEFORE adjustiung the optimizer parms (unless you are on 9i or earlier, where optimizer parm changes are sometimes the only solution).
Please note that Oracle11g has codified the well-known empirical approach to holistic tuning with the SPA (SQL Performance Analyzer), which allows you to find optimal settings for your init.ora parms by testing with a representative workload:
http://www.dba-oracle.com/oracle11g/oracle_11g_sql_performance_advisor.htm
Are the steps above sufficient for collecting system statistics on an OLTP only database? Yes, that should work.
Remember, if you are on 10g or later, and you have the time to "optimize" your statistics, you can correct the one root cause of the sub-optimal plans, but some shops must also adjust their optimizer parameters. See my notes here:
http://www.dba-oracle.com/t_dbms_stats_gather_system_stats.htm
The dbms_stats.gather_system_stats procedure is very similar to my script for setting optimizer_index_cost_adj, where I compare the relative costs of sequential and scattered read times:
select
sum(a.time_waited_micro)/sum(a.total_waits)/1000000 c1,
sum(b.time_waited_micro)/sum(b.total_waits)/1000000 c2,
sum(a.total_waits) /
sum(a.total_waits + b.total_waits)
) * 100 c3,
sum(b.total_waits) /
sum(a.total_waits + b.total_waits)
) * 100 c4,
sum(b.time_waited_micro) /
sum(b.total_waits)) /
(sum(a.time_waited_micro)/sum(a.total_waits)
) * 100 c5
from
dba_hist_system_event a,
dba_hist_system_event b
where
a.snap_id = b.snap_id
and
a.event_name = 'db file scattered read'
and
b.event_name = 'db file sequential read';
Hope this helps. . . .

How much OPTIMIZER_INDEX_CACHING and OPTIMIZER_INDEX_COST_ADJ should I set?
Dear all:
I use CBO and the default parameter of the "OPTIMIZER_INDEX_CACHING" is 0 and "OPTIMIZER_INDEX_COST_ADJ" is 100 these two parameters will impact of CBO. how much OPTIMIZER_INDEX_CACHING should I set?
my environment is Oracle 9.2.0.8 (64bit)
Regards

Dear Nicolas:
Thank you for your quick reply, I have to say I have to modify the default setting of these parameters ,because we use EBS 11.5.9 and the database is more powerful then ever before and the SQL explain plan still show to do sorting with high cost.So I think I will refer to the articles of the provided and find the answers.
Before you start playing around with these parameters, have you checked very carefully that you are conforming to the suggestions offered for all the parameters listed in the installation notes for EBS, and doing what you're supposed to do with system statistics ?

Pagination query help needed for large table - force a different index
I'm using a slight modification of the pagination query from over at Ask Tom's: [http://www.oracle.com/technology/oramag/oracle/07-jan/o17asktom.html]
Mine looks like this when fetching the first 100 rows of all members with last name Smith, ordered by join date:
SELECT members.*
FROM members,
SELECT RID, rownum rnum
FROM
SELECT rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
WHERE rownum <= 100
WHERE rnum >= 1
and RID = members.rowidThe difference between this and the one at Ask Tom's is that my innermost query just returns the ROWID. Then in the outermost query we join the ROWIDs returned to the members table, after we have pruned the ROWIDs down to only the chunk of 100 we want. This makes it MUCH faster (verifiably) on our large tables, as it is able to use the index on the innermost query (well... read on).
The problem I have is this:
SELECT rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindateThis will use the index for the predicate column (last_name) instead of the unique index I have defined for the joindate column (joindate, sequence). (Verifiable with explain plan). It is much slower this way on a large table. So I can hint it using either of the following methods:
SELECT /*+ index(members, joindate_idx) */ rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
SELECT /*+ first_rows(100) */ rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindateEither way, it now uses the index of the ORDER BY column (joindate_idx), so now it is much faster as it does not have to do a sort (remember, VERY large table, millions of records). So that seems good. But now, on my outermost query, I join the rowid with the meaningful columns of data from the members table, as commented below:
SELECT members.* -- Select all data from members table
FROM members, -- members table added to FROM clause
SELECT RID, rownum rnum
FROM
SELECT /*+ index(members, joindate_idx) */ rowid as RID -- Hint is ignored now that I am joining in the outer query
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
WHERE rownum <= 100
WHERE rnum >= 1
and RID = members.rowid -- Merge the members table on the rowid we pulled from the inner queriesOnce I do this join, it goes back to using the predicate index (last_name) and has to perform the sort once it finds all matching values (which can be a lot in this table, there is high cardinality on some columns).
So my question is, in the full query above, is there any way I can get it to use the ORDER BY column for indexing to prevent it from having to do a sort? The join is what causes it to revert back to using the predicate index, even with hints. Remove the join and just return the ROWIDs for those 100 records and it flies, even on 10 million records.
It'd be great if there was some generic hint that could accomplish this, such that if we change the table/columns/indexes, we don't need to change the hint (the FIRST_ROWS hint is a good example of this, while the INDEX hint is the opposite), but any help would be appreciated. I can provide explain plans for any of the above if needed.

Not sure what advantage you are trying to show here. But considering that we are talking about pagination query here and order of records is important, your 2 queries will not always generate output in same order. Here is the test case:

SQL> set autotrace off
SQL> spool offAs you will see, the join query here has to have an ORDER BY clause at the end to ensure that records are correctly sorted. You can not rely on optimizer choosing NESTED LOOP join method and, as above example shows, when optimizer chooses HASH JOIN, oracle is free to return rows in no particular order.
The query that does not involve join always returns rows in the desired order. Adding an ORDER BY does add a step in the plan for the query using join but does not affect the other query. -
I have a query which is taking long time. Is there any way I can improve the query to shorten its time of execution.
I have given below the details of it.

obviously the problem you are having is described by the following lines of your execution plan

| 24 | TABLE ACCESS FULL | PA_PROFILE | 1109 | 44360 | 9
You don't have a "real" "WHERE" condition in the query that could lead the Oracle CBO to consider using an index.
This leads to a full scan of PA_PMP_VISITS and PA_PROFILE and subsequently -in order to process the join condition between these two tables-
to this "HASH JOIN RIGHT OUTER". You cannot avoid this, with the current WHERE condition ...
Following thoughts :
1) Try narrowing down your result set by specifying a "real" WHERE Condition on one of the two tables, specifying an indexed column
2) If this cannot be done, try using query parallelism (parallel hint). This will give you acceptable SQL-execution times.
3) If this is not possible, there would be a third approach : You could consider the definition of an index on "pa.regn" and use a hint on your query in order to use it. Due to your order condition there is a possibility that CBO is going to use it, especially if you specify WHERE ROWNUM < ...

Help needed for hash_area_size setting for Datawarehouse environment
We have an Oracle 10g Datawarehousing environment , running on 3 - node RAC
with 16 GB RAM & 4 CPUs each and roughly we have 200 users and night jobs running on this D/W .
We find that query performance of all ETL Processes & joins are quite slow .
How much should we increase the value of hash_area_size parameter for this Datawarehouse environment ? This is a Production database, with Oracle Database 10g Enterprise Edition Release 10.1.0.5.0.
We use OWB 10g Tool for this D/W and we need to change the hash_area_size to increase the performance of the ETL Processes.
This is the Oracle init parameter settings used, as shown below : -
Kindly suggest ,
Thanks & best regards ,

CBO generating different plans for the same data in similar Environments
Hi All
I have been trying to compare an SQL from 2 different but similar environments build of the same hardware specs .The issue I am facing is environment A, the query executes in less than 2 minutes with plan mostly showing full table scans and hash join whereas in environment B(problematic), it times out after 2 hours with an error of unable to extend table space . The statistics are up to date in both environments for both tables and indexes . System parameters are exactly similar(default oracle for except for multiblock_read_count ).
Both Environment have same db parameter for db_file_multiblock_read_count(16), optimizer(refer below),hash_area_size (131072),pga_aggregate_target(1G),db_block_size(8192) etc . SREADTIM, MREADTIM, CPUSPEED, MBRC are all null in aux_stats in both environment because workload was never collected i believe.
Attached is details about the SQL with table stats, SQL and index stats my main concern is CBO generating different plans for the similar data and statistics and same hardware and software specs. Is there any thing else I should consider .I generally see environment B being very slow and always plans tend to nested loops and index scan whereas what we really need is a sensible FTS in many cases. One of the very surprising thing is METER_CONFIG_HEADER below which has just 80 blocks of data is being asked for index scan.

HOW TO: Post a SQL statement tuning request - template posting
This post is not a question, but similar to Rob van Wijk's "When your query takes too long ..." post should help to improve the quality of the requests for SQL statement tuning here on OTN.
On the OTN forum very often tuning requests about single SQL statements are posted, but the information provided is rather limited, and therefore it's not that simple to provide a meaningful advice. Instead of writing the same requests for additional information over and over again I thought I put together a post that describes how a "useful" post for such a request should look like and what information it should cover.
I've also prepared very detailed step-by-step instructions how to obtain that information on my blog, which can be used to easily gather the required information. It also covers again the details how to post the information properly here, in particular how to use the \ tag to preserve formatting and get a fixed font output:
http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
So again: This post here describes how a "useful" post should look like and what information it ideally covers. The blog post explains in detail how to obtain that information.
In the future, rather than requesting the same additional information and explaining how to obtain it, I'll simply refer to this HOW TO post and the corresponding blog post which describes in detail how to get that information.
*Very important:*
Use the \ tag to enclose any output that should have its formatting preserved as shown below.
So if you want to use fixed font formatting that preserves the spaces etc., do the following:
\ This preserves formatting
\And it will look like this:
This preserves formatting
. . .Your post should cover the following information:
1. The SQL and a short description of its purpose
2. The version of your database with 4-digits (e.g. 10.2.0.4)
3. Optimizer related parameters
4. The TIMING and AUTOTRACE output
5. The EXPLAIN PLAN output
6. The TKPROF output snippet that corresponds to your statement
7. If you're on 10g or later, the DBMS_XPLAN.DISPLAY_CURSOR output
The above mentioned blog post describes in detail how to obtain that information.
Your post should have a meaningful subject, e.g. "SQL statement tuning request", and the message body should look similar to the following:
*-- Start of template body --*
The following SQL statement has been identified to perform poorly. It currently takes up to 10 seconds to execute, but it's supposed to take a second at most.
This is the statement:
select

t_demo
where
type = 'VIEW'
order by
id;It should return data from a table in a specific order.
The version of the database is 11.1.0.7.
These are the parameters relevant to the optimizer:

I'm sure that if you follow these instructions and obtain the information described, post them using a proper formatting (don't forget about the \ tag) you'll receive meaningful advice very soon.
So, just to make sure you didn't miss this point:Use proper formatting!
If you think I missed something important in this sample post let me know so that I can improve it.

Odd behaviour of forum software -
Slow table creation after upgrade from 10.2.0.3 to 11.2.0.1 using DBUA
I've recently completed a database upgrade from 10.2.0.3 to 11.2.0.1 using the DBUA.
I've since encountered a slowdown when running a script which drops and recreates a series of ~250 tables. The script normally runs in around 19 seconds. After the upgrade, the script requires ~2 minutes to run.
By chance has anyone encountered something similar?
The problem may be related to the behavior of an "after CREATE on schema" trigger which grants select privileges to a role through the use of a dbms_job call; between 10g and the database that was upgraded from 10G to 11g. Currently researching this angle.
I will be using the following table creation DDL for this abbreviated test case:
create table ALLIANCE (
ALLIANCEID NUMBER(10) not null,
NAME VARCHAR2(40) not null,
CREATION_DATE DATE,
constraint PK_ALLIANCE primary key (ALLIANCEID)
using index
tablespace LIVE_INDEX
tablespace LIVE_DATA;When calling the above DDL, an "after CREATE on schema" trigger is fired which schedules a job to immediately run to grant select privilege to a role for the table which was just created:
create or replace
trigger select_grant
after CREATE on schema
declare
l_str varchar2(255);
l_job number;
begin
if ( ora_dict_obj_type = 'TABLE' ) then
l_str := 'execute immediate "grant select on ' ||
ora_dict_obj_name ||
' to select_role";';
dbms_job.submit( l_job, replace(l_str,'"','''') );
end if;
end;
{code}
Below I've included data on two separate test runs. The first is on the upgraded database and includes optimizer parameters and an abbreviated TKPROF. I've also, included the offending sys generate SQL which is not issued when the same test is run on a 10g environment that has been set up with a similar test case. The 10g test run's TKPROF is also included below.
The version of the database is 11.2.0.1.
These are the parameters relevant to the optimizer for the test run on the upgraded 11g SID:

Edited by: user8598842 on Mar 11, 2010 5:08 PMSo while this certainly isn't the most elegant of solutions, and most assuredly isn't in the realm of supported by Oracle...
I've used the DBMS_IJOB.DROP_USER_JOBS('username'); package to remove the 194558 orphaned job entries from the job$ table. Don't ask, I've no clue how they all got there; but I've prepared some evil looks to unleash upon certain developers tomorrow morning.
Not being able to reorganize the JOB$ table to free the now wasted ~67MB of space I've opted to create a new index on the JOB$ table to sidestep the full table scan.
CREATE INDEX SYS.JOB_F1_THIS_NEXT ON SYS.JOB$ (FIELD1, THIS_DATE, NEXT_DATE) TABLESPACE SYSTEM;The next option would be to try to find a way to grant the select privilege to the role without using the aforementioned "after CREATE on schema" trigger and dbms_job call. This method was adopted to cover situations in which a developer manually added a table directly to the database rather than using the provided scripts to recreate their test environment.
I assume that the following quote from the 11gR2 documentation is mistaken, and there is no such beast as "create or replace table" in 11g:
http://download.oracle.com/docs/cd/E11882_01/server.112/e10592/statements_9003.htm#i2061306
"Dropping a table invalidates dependent objects and removes object privileges on the table. If you want to re-create the table, then you must regrant object privileges on the table, re-create the indexes, integrity constraints, and triggers for the table, and respecify its storage parameters. Truncating and replacing have none of these effects. Therefore, removing rows with the TRUNCATE statement or replacing the table with a *CREATE OR REPLACE TABLE* statement can be more efficient than dropping and re-creating a table." -
Hi everybody!
I have a problem. Some weeks ago I opened a post related to this issue. We have two dataguards with dataguard broker. One of them is resync (thanks to mseberg and this forum) and now I have problems with the other.
Once I have learned how to configure and start/stop dataguard broker, I have a more basic problem, which is to resync it. I follow a process, where I backup the primary with RMAN, I copy the rman files to the other server with the controlfile, at once, I recover with rman again.
The problem is that it is too big, 2 hours for backing it up more or less, and when I restore it, no archivelog list appears being syncronized.
I have followed the same process than the other one and I can't resync it. I think there is something at my params or something new at 11g version...

### PHASE 2: User inputs
Upgrade phase started at Wed Oct 18 21:22:19 2006
Processing Metadata File: upg/common/inputchk/inputchk.met Running upg/common/inputchk/inputchk.pl ### Verify that the database has been backed up
Step started at Wed Oct 18 21:22:19 2006
Before beginning the upgrade, it is important that you backup your database.
Have you backed up your database (y/n)? [y]: y
Ask user for schema and database details
Enter the name of schema that you would like to upgrade [PORTAL]: portal
Enter the password for the schema that you would like to upgrade [portal]:
Enter the password for the SYS user of your database [CHANGE_ON_INSTALL]:
Enter the TNS connect string to connect to the database [ORCL]: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=portaldb.bizmatch.com.cn)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=IASDB.bizmatch.com.cn)))
Responses to the above questions will now be recorded in the file
upgrade.in. Placeholders are recorded instead of actual passwords,
for security reasons. If you wish, this file can be edited and used
as the standard input for a subsequent run of upgrade.pl.
### Verify database connection information.

Pre-Check Completed at Wed Oct 18 21:22:32 2006Hi,
Its good that u pasted the complete log file. In your environment you have to run this upgrade tool only once from any of the middle tier.
And with respect to your error that u got in precheck is quite simple. All u have to do is just run this script from by connecting to portal schema using sqlplus.
Run dropupg.sql
Location-------- /raid/product/OraHome_1/upgrade/temp/portal/prechktmp/dropupg.sql
Later you re-run the upgrade tool and let me know the status.
Good luck

Index vs Full Scan - Parallelism
Hi everyone, i have an problem my scenario is a plataform Linux x64 bits in RAC 10gR2 (10.2.0.5) and we are migrating to RAC 11gR2 (11.2.0.3.3) in AIX 7.1 and my query: Update movimientos set ESTADOENCOLADO = :"SYS_B_0" where tipoproceso = :"SYS_B_1" and ESTADOENCOLADO = :"SYS_B_2"; in my Oracle 10g uses an index in the table MOVIMIENTOS and in the Oracle 11g the optimizer takes a FULL SCAN.
In both database server the statistics are updated with estimate 100% even the system statistics, fixed tables and data dictionary are taken its statistics.
I review the cost in both plans in Oracle 11g (with a full scan and other using a hint to index) and the full scan plan has less cost that the index. My db_file_multiblock_read_count is not set up, but in the Oracle 10g i see a value of 16 and in the 11g i see a value dinamic of 192. Understand that it too helps an uses a full scan.
The problem is that the query taken in Oracle 10g 20 minutes, but in the Oracle 11g with full scan 1.4 h whereas with a hint takes too 20 minutes.
I use the advisor tuning and no recommendations.
So basicaly i fix it modifily my parameter optimizer_index_cost_adj to 80 and it works well.
My doubt is why Oracle11gR2 says me that a full scan is faster than take an index when in the real live it is not working in this mode. I need some posible reasons please.
Thank you very much if somebody can help me with some tip or idea.

Well if you can't figure it out by looking at the plans what makes you think anyone can figure it out without looking at them?
We have no idea what the plans contain. Post the plans, record counts for the table(s) involved, record counts for any filter predicates and the other information needed. See the FAQ for how to post a tuning request and the information needed.
