Force index query?
i don't have any index on subscriber_all table, but i am still using /*+ index(SUBSCRIBER_ALL, SUBSCRIBER_ALL_I1)*/ in a select statement
in that case will oracle create automatic index on SUBSCRIBER_ALL table (index name-SUBSCRIBER_ALL_I1) based on (Subscriber_ID) where clause?
select /*+index(SUBSCRIBER_ALL, SUBSCRIBER_ALL_I1)*/ to_char(Acc_type) from SUBSCRIBER_ALL where Subscriber_ID = :1
No!
You should create index (to determine btree, bitmap, combine etc) by yourself.
Ex: SQL> create index SUBSCRIBER_ALL_subscr_id_idx on SUBSCRIBER_ALL(Subscriber_ID);
firstly provide us your table structure and size, also how often DML action happens on this table?
If your table has unique, primary key, automatically index was created!!!

INTERMEDIA TEXT INDEX를 사용하는 QUERY의 TUNING
제품 : ORACLE SERVER
작성날짜 : 2002-04-12
INTERMEDIA TEXT INDEX를 사용하는 QUERY의 TUNING
===============================================
Purpose
Intermedia text를 사용하는 query의 속도를 향상시킬 수 있는 방안을
알아보자.
Explanation
1. Make analyze all the table in the query
text index를 이용하는 Query 안의 모든 Table을 analyze 해 주십시요.
예를 들어 다음의 command를 이용할 수 있습니다.
ANALYZE TABLE <table_name> COMPUTE STATISTICS;
or
ANALYZE TABLE <table_name> ESTIMATE STATISTICS 1000 ROWS;
or
ANALYZE TABLE <table_name> ESTIMATE STATISTICS 50 PERCENT;
2. Using FIRST_ROWS hint
더 좋은 response time 을 위해서 first_rows hint 를 사용해 보십시요.
database에 기본적으로 설정된 optimizer mode는 choose mode입니다.
이것은 전체 처리시간(throughput)을 가장 빠르게 하기 위한(all_rows mode)
plan을 따르기 때문에 user의 입장에서는 first_rows 보다는 늦다고 느낄 수
있습니다.
Query에 다음과 같이 hint를 주고 performance를 확인해 보십시요.
select /*+ FIRST_ROWS */ pk, col from ctx_tab
where contains(txt_col, 'test', 1) > 0;
단, first_rows hint를 이용하는 경우 자동으로 score 순서대로
ordering 되지 않습니다. 왜냐하면 단어에 부합하는 문서를 찾는대로
즉시 결과로 나타내 주기 때문입니다.
3. Make sure text index is not fragmented
insert, delete 가 많이 되는 table의 경우 index fragment를 제거해 주어야
합니다. Index fragmentation 은 다음과 같이 확인할 수 있습니다.
select count(*) from dr$<indexname>$i; -> A
select count(*) from (select distinct(token_text) from dr$<indexname>$i); -> B
위의 결과가 A/B 의 값이 3:1 보다 크면 optimize_index 를 실행해 주시는
것이 좋습니다. 다음과 같은 command로 index optimization을 할 수 있습니다.
alter index <index_name> rebuild online
parameters('optimize full unlimited');
index rebuild중에 online option을 주면 rebuild하는 중에도 계속 index를
사용할 수 있게 됩니다. 하지만, 가능하면 사용자가 없을 때 rebuild하는 것이
좋습니다.
4. Check execution plan and sql trace.
기본적인 여러 가지 작업들에도 속도가 별로 향상되지 않는다면, 직접
sql trace를 떠서 Execution plan등을 확인해 보는 것이 필요합니다.
예를 들어 SQL*PLUS에서 다음과 같이 sql trace를 뜹니다.
alter session set timed_statistics=true;
alter session set sql_trace=true;
select ..... -> execute the query
실행 후,
exit
user_dump_dest 에 지정된 directory에 trace 가 떨어지면 다음과 같은
command로 tkprof 를 떠서 내용을 확인합니다.
$ tkprof <tracefilename> <outputfilename> explain=username/password

Bulletin#10134 : SQL trace와 tkprof 사용 방법 -
Hello everbody,
How do I retrieve all the NON indexed query's used in the database? I want to find out which ones I need to optimize.
thanks JohnHello
That's not as easy as it sounds. Creating indexes for every query that does not use one could very easily cause more problems than it fixes. Full table scans are not evil, they are often the fastest way to access a relatively large portion of data in a table.
If you have issues with performance in your database you need to know exactly what they are, and you can get a very good idea by using statspack.
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96533/statspac.htm#21793
Once you have the right metrics, you can make an informed decision as to what the correct course of action is to solve any performance problems you are having. Without these metrics, you are groping in the dark.

Oracle Hint on Table MKPF and MSEG : force index MSEG~M to be utilize
Hi Experts, I'm quite new to ABAP performance tuning, I try to put details as much as I can in my question below, just to have a quick overview of my problem below, I want to use/force in my SQL below to force the utilization of index MSEG~M.
added an Oracle Hint forcing index MSEG~M
SELECT MATNR BWART MENGE
FROM MKPF
INNER JOIN MSEG
ON MKPFMANDT EQ MSEGMANDT
AND MKPFMBLNR EQ MSEGMBLNR
AND MKPFMJAHR EQ MSEGMJAHR

%_hints oracle u2018INDEX(u201CMKPFu201D u201CMSEG~Mu201D)u2019.
Note: I'm assuming that you'll take not some comments on further enhancement:
- " INTO CORRESPONDING FIELDS "
- use of field symbols
- I didn't modify it yet since my focus if for MSEG~M
- cannot make material number as mandatory field
Objective: Force to use index MSEG~M
Problem:
After adding the Oracle Hint, I did the analysis in ST05 and it seems like index M is still not being forcefully
utilize instead MSEG~0 is being used.
I replaced the Oracle Hint with:
%_hints oracle u2018INDEX(u201CT_01u201D u201CMSEG~Mu201D)u2019.
In ST05, I can get see that index MSEG~M is now being utilize BUT worst thing happened after applying this, the program timed out.
I already take a look on the following Notes: 129385, 130480, 772497, 162034, 818321 but nothing seems to be helpful in my problem.
Questions:
1. In syntax %_hints oracle u2018INDEX(u201CT_01u201D u201CMSEG~Mu201D)u2019. T_01 stands for MKPF right which is the first table, do you what's the reason for the program time out after adding this Oracle Hint? Is this the proper syntax?
2. How can I force in my code to use index MSEG~M without any program timeout?
For the whole source code of my question above, please see the link:
http://rapidshare.com/files/211740852/ZDXX0028.txt.htmlHi Thomas, thanks with the prompt reply (even if it's Saturday )
Yes, MKPF~BUD is being used.
The budat selection is narrowed to 28 days though users can input any date range, a warning message will just be displayed if budat selection exceeded.
Yes, optimizer usually chooses the right index; I'm not in as the same experience as you are though, but I find it interesting that after I added the Oracle hints (several combination) the performance of the program was optimize up to 40% to 50%.
I uploaded a detailed SQL trace and the ABAP change done in my program, if you'll notice in the summary of the changes, after adding some hints, the duration of the program was improved..
(SQL Trace Summary of my program) this worth taking a look
http://rapidshare.com/files/211870091/ZD28_SQL_Trace.zip.html
I made a custom index in MSEG, but unfortunately I doubt that it will be approve by our performance capacity team. But I somehow have a hunch that this will further optimize the program.

BWART Movement Type (Inventory Management)

What do you think Thomas and SAP experts?

Force index not getting picked up while running the SQL Query
Hi All,
We are facing an issue with one SQL Query. We have created a custom Index and we are using that index in our query by using the following syntax:
/*+INDEX(ol XXEXH_ORDER_LINES_N2)*/
Where
ol – Table Alias Name
XXEXH_ORDER_LINES_N2 – Index Name
But still the index is not getting picked up in the Explain Plan.
If any one of you have faced a similar issue then please let us know how you had resolved it.
Appreciate your help.

Materialized views - schedule, indexes, query rewrite, etc.
I'm trying to get the hang of materialized views and need some help . . .
running Oracle 10gR2
I created a materialized view as follows:
CREATE MATERIALIZED VIEW "MY_SCHEMA"."USERS"
AS
SELECT * FROM "USERS"@PRODUCTION -- to copy the USERS table from my production database to this database
Worked fine. So far so good. Then, I altered it to schedule the refresh:
ALTER MATERIALIZED VIEW "MY_SCHEMA"."USERS" REFRESH FORCE START WITH SYSDATE NEXT TRUNC(SYSDATE + 1) + 4/24
-- to schedule a refresh immediately (SYSDATE) and every morning thereafter at 4:00 am (I think)
then, I wanted to enable query rewrite, so I issued the following command:
ALTER MATERIALIZED VIEW "MY_SCHEMA"."USERS" ENABLE QUERY REWRITE;
and I got the
ALTER MATERIALIZED VIEW succeeded.
message for both of those commands (I'm doing this in SQL Developer).
Then, I edit the materialized view in SQL Developer, click on the 'SQL' tab, and get the following:
CREATE MATERIALIZED VIEW "MY_SCHEMA"."USERS"
ORGANIZATION HEAP PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645

"SwipePassword","USERS"."PwdLastChanged" "PwdLastChanged","USERS"."Audit" "Audit","USERS"."IsInstructor"
"IsInstructor" FROM "USERS"@PRODUCTION.REGRESS.RDBMS.DEV.US.ORACLE.COM "USERS";
The problems I've encountered so far:
1) I created this two days ago and changed the value of one column in one row in the 'source' USERS table
(USERS@PRODUCTION) as a test case. So far, that change has not propagated over to my materialized view even though
it has had two chances to do so (yesterday morning at 4:00 am and this morning at 4:00 am).
2) I enabled QUERY REWRITE. Why does it still show DISABLE?
3) The primary key of the table came over (as far as I can tell) because it shows in SQL Developer. However, the
indexed columns are no longer indexed. Do I need to recreate those indexes manually and will they persist?
4) As you have guessed, I have just taken the plunge into materialized views, and have not been able to find
anything on the Web along the lines of 'Materialized Views for Dummies'. So, any and all advice/suggestions/help
will be welcome.
Thanks,
CarlThe Refresh would be executed by a job submitted in the background.
Query USER_JOBS (or DBA_JOBS) to see if a job has been submitted and if it has been running (you'd be able to see LAST_DATE, LAST_SEC and NEXT_DATE and NEXT_SEC). \
If the Refresh job has been failing the FAILURES count would be incremented. If there are 16 consecutive failures, the job is marked BROKEN. (if a job fails, Oracle retries it automatically and keeps retrying till it is BROKEN). If the job has been failing you would get messages in the database instance alert log file and trace files.
If the Refresh job has not been running check the parameter value for JOB_QUEUE_PROCESSES -- a value of 0 would not run in jobs in the USER_JOBS/DBA_JOBS view. Ask the DBA to increase set this parameter to at least 1.

Forcing a query to use a differnet plan
I have one database where a sql plan appears to be correct through tests. In another database the join order is flipped. Data is relatively close. Hinting the query would require a code change. What is the easiest to force the plan from the other database?
if this new plan does not work, what is the easiest way to revert back.Hi,
Another option is SQL Plan Management
SQL Plan Management (SPM) prevents performance regressions resulting from sudden changes to the execution plan of a SQL statement by providing components for capturing, selecting and evolving SQL plan information. Changes to the execution plan may result from database upgrades, system and data changes, application upgrade or bug fixes. When SPM is enabled, the system maintains a plan history that contains all plans generated by the optimizer and stores them in a component called plan baseline. Among the plan history in the plan baseline, plans that are verified not to cause performance regression are marked as acceptable. The plan baseline is used by the optimizer to decide on the best plan to use when compiling a SQL statement. Repository stored in a data dictionary of plan baselines and statement log maintained by the optimizer is called SQL Management Base (SMB).

Hello
Had a query on oracle Text Index.
1. I have created a table with column ID as sequence & column description as Varchar2(500)
2. Inserted 3 records
3. I created the Oracle Text index on column "description" as INDEXTYPE IS CTXSYS.CONTEXT
4. Run a select using "contains" , get the records as required.
5. I insert another new record & commit;
6. Run the same old query using contains but for the new records I get 0 records
7. Drop the Index and Recreate the index using same old index on column "description" as INDEXTYPE IS CTXSYS.CONTEXT
8. Run the same old query using contains but for the new records and now I get the records as required.
Does that mean every time I insert new records I have to rebuild the Oracle Text Index ?
Your Help will be much appreciated
Regards
HarshadYou need to use some method of updating your index. You can drop and recreate or you can rebuild or you can use ctx_ddl.sync_index or you can include sync(on commit) in your parameters when you create the index or various other methods of periodic synchronization and optimization.

Domain index query takes 12 hours to execute
Hi Friends,
My query which uses domain index takes 12 hours to execute. Can you please help me tuning this query?
select /*+ NO_UNNEST ORDERED index_ffs(Term idx_recanon_term_ysm1) parallel_index(Term, idx_recanon_term_ysm1, 8) */ term.rowid
from cmpgn.recanon_search_terms,cmpgn.recanon_term_ysm Term
where cmpgn.recanon_search_terms.search_type=3 and
contains(Term.RAW_TERM_TEXT,cmpgn.recanon_search_terms.search_text) > 0 and
Term.pod_id=11
Thanks in advance.
Regards
BalaFirst your driving table is recanon_search_terms to get the required search terms, then use them to query Oracle Text. What you are trying to do is to get a subset of table term first and than run every individual row of table term against the search terms. This approach will take a very long time.
Not sure what you want to do, but it looks something I have been working on previously. As far I can see there is a table with controlled terms which are matched against other raw terms in a text document using Oracle Text. The issue is that you do a join in the contains clause without knowing the number of query expressions formed. It can be that 7 thousand individual queries run at once, than use indexes of the other predicates, do some sorting, etc. which would explain the long time needed. It will probably run out of memory causing all sorts of issues.
As a quick fix try first following statement without hints.
Tell us how many rows you get, the distinct counts for pod_id and search_type and how long it takes.
CREATE TABLE test_table AS
select term.pod_id pod_id, cmpgn.recanon_search_terms.search_type search_type, term_primary_key, ....
from cmpgn.recanon_search_terms,cmpgn.recanon_term_ysm Term
where contains(Term.RAW_TERM_TEXT,cmpgn.recanon_search_terms.search_text) > 0
Create index test_idx on test_table(pod_id, search_type) and use test_table instead to get the results, just by providing pod_id and search_type without the join in the contains clause.
SELECT ..
FROM test_table
WHERE pod_id = X
AND search_type = Y
Maybe this approach is sufficient for your purpose. For sure, it will give you instant results. In that case a materialized view instead of the table could work for maintenance reasons; I had some issues with materialized views for above scenario.
However check very carefully the results. I would have some doubts that all rows in search_text form a valid query expression for Oracle Text. If search_text has just single tokens or phrases wrapping curly brackets around will probably resolve the issue.
Think about to form one query expression through a function call instead of a table join inside the contains clause. Sometimes to run a set of individual queries are faster than one big query.
select term.rowid --, form_query_exrpession(3) query_exrpession
from cmpgn.recanon_term_ysm Term
where contains(Term.RAW_TERM_TEXT, form_query_exrpession(3)) > 0
The above function will form one valid Oracle Text query expression by using the table recanon_search_terms inside the function. This approach normally helps, at least in debugging and fine-tuning. Avoid using bind variables first in order to identify highly skewed distribution of search_type.
The other performance issue is the additional predicate of pod_id = X, here the suggestion from radord works very well. If you want to get your hands dirty have a look at user_datastore in the Oracle Text documentation, this will give you all the freedom you want. -
Force Index and Group By Exception
Hello,
I'm using Oracle 8 and PL/SQL Developer 7 and when i want to perform this query :
select

where
creation_date between to_date('26/01/2006', 'DD/MM/YYYY') and to_date('30/06/2006', 'DD/MM/YYYY')
group by trunc(creation_date, 'D')
I have the Exception : ORA-00979 : not a GROUP BY expression
Do you have a solution for this please ?

can anybody explains whats the reason...
the table is having around 1.5 crore records
regardsThe execution plan clearly shows that Oracle thinks only one row is going to match that condition on the index ("Card=1"). Is that a true statement? If not, you should make sure your stats are accurate. If the data is highly skewed, you may need to put a histogram on that column.
Another possibility is that the index is on much slower disks than the table. Although, I can't imagine any range scan on an index that has only one matching value taking that long. How about doing a full trace (SET AUTOTRACE ON) and posting the logical and physical i/o information? -
Force index not getting picked up while running the SQL Quer
Hi All,
We are facing an issue with one SQL Query. We have created a custom Index and we are using that index in our query by using the following syntax:
/*+INDEX(ol XXEXH_ORDER_LINES_N2)*/
Where
ol – Table Alias Name
XXEXH_ORDER_LINES_N2 – Index Name
But still the index is not getting picked up in the Explain Plan.
If any one of you have faced a similar issue then please let us know how you had resolved it.
Appreciate your help.
