Please hep in tuning the query
Hi,
I have the following query
SELECT* FROM PRICE_LIST WHERE ITEM_CODE NOT IN (SELECT
PRODUCT_ATTR_VAL_DISP FROM QP_LIST_LINES_V WHERE LIST_HEADER_ID=6014)
AND COUNTER BETWEEN 10001 AND 20000
We have 10,000 rows in PRICE_LIST
and 24000 rows QP_LIST_LINES_V
Causing too much cardinality and cost.
Before we did not have any index on PRICE_LIST, later we created an index for COUNTER but the problem still exists.
It is taking too much time
Thanks

Please help!!! Tuning the query
Hi,
I am using Oracle BDBXML 2.4.16. In the following, policyContainer.dbxml has around 1000 documents and productsContainer.dbxml around 10 documents. The following query is taking around 6 - 8 seconds to fetch the data of around 300 records. I have created node-element-equality-string indexes on PolicyEvent, PolicyStatus, Archived, IsLatest, ProductID and CompanyID.
I am novice on Query tuning. Can someone please help me to tune the following query. I have posted the query plan as well.
Thanks in Advance!!
Balakrishna.

</XQuery>The good news is that your indexes are being used (anywhere in the query plan where you see index="node-element-equality-string"), the bad news is that the entire policyContainer is being scanned several times (<SequentialScanQP container="policyContainer.dbxml" nodeType="element"/>). Your best bet is to upgrade to dbxml-2.5.16, since that has several improvements to the optimizer that should optimize away those scans. Failing that, use the shell command (dbxml) to add and remove indexes and see how that changes the query plan and speed. The following line is what is causing the scans:
{$state/*,$header/*,$datatable/*}So add indexes that will help to locate those nodes, or change that line so that the query is faster.

It's a good job you're not a computer program, you wouldn't have even compiled.
so, points to note:
This is a forum of volunteers. There's no such thing as an Urgent question here, and it's considered rude to suggest your question is urgent, as that indicates you want immediate attention from the people who are giving up their own time to help, and who have their own jobs to do. It's also rude for the other people who are asking questions, as everyone would like an answer to their problem as soon as possible, so what makes you any more special? An urgent issue is one where a live system is down potentially putting people's lives at risk or causing a company to lose money, or somehow damage their services. Such issues should be logged with Oracle Support, not on the free OTN forums.
Next, when you post your question, ensure you provide all the information that is needed for people to be able to help you. Read the FAQ posts which point to useful threads indicating what information is required, especially for tuning requests.
Finally, when your questions have been answered, it is common courtesy to mark them as answered (and award points if appropriate), otherwise it indicates that you have no respect for the people who are helping you.
If you follow all the advice above, you will end up creating a good question that people will be willing to help you with. If you don't follow the advice above, such as in this question you've posted, you will find that few experts will bother to help (or if they post it will not likely be helpful advise you receive). The choice is yours. -
Parameters to be considered for tuning the QUERY Performance.
Hi Guys
I wanted to identify the Query which is taking more resources through the Dynamic performance views and not through OEM.I wanter to tune the Query.
Please suggest me on this. Also i wanted to know what are all the parameters to be considered for tuning a query like Query execution time, I/O Hits, Library cache hits, etc and from which performance view these paramaters can be taken. I also wanted to know how to find the size of library cache and how much queries can be holded in a library cache and what will be the retention of queries in library cache and how to retrive the queries from Library cache.
Thanks a lot
Edited by: user448837 on Sep 23, 2008 9:24 PMHmm there is a parameter called makemyquery=super_fast, check that ;-).
Ok jokes apart, your question is like asking a doctor that when a person is sick than how to troubleshoot his sickeness? So does a doctor start giving medicine immediately? No right? He has to check some symptoms of the patient. The same is applicable to the query also. There is no view as such which would tell you the performance of the query ie it is good or bad. Tell me if a query is taking up 5 minutes and I come and tell you this, what would you say its good or bad or the query took this much CPU time what would you say, its too much or too less? I am sure your answers would be "it depends". That's the key point.
The supermost point in the performance check is two things, one the plan of the query. What kind of plan optimizer took for the query and whether it was really good or not? There are millions os ways to do som ething but the idea is to do it in the best way. That's what the idea of reading explain plan. I would suggest get your self familiar with explain plan's various paths and their pros and cons. Also about the query's charectristics, you can check V$sql, v$sqlarea , V$sql_text views.
Your other question that you want to check the size of the library cache , its contents and the retention, I would say that its all internally managed. You never size library cache but shared pool only. Similary the best bet for a dba/developer is to check the queries are mostly shareable and there wont be any duplicate sqls. So the cursor_sharing parameter can be used for this. The control is not given to us to manage the rentention or the flushing of the queries from the cache.

But I am wondering why there is TABLE ACCESS BY INDEX ROWID| JOURNAL_CASH_DRAWER when this col is availabe in the indexed table .
Can anyone Please suggest what improvements can be done on this query.WIll change in the table order will have some performance boost.
Please suggest ..

Friend -
Pls see this attached query. This is hitting a table which has around 110 mil recs. And this takes around 60 min to execute. IS there any way to tune it better? I am assuming that because this uses the ' With tmp as' clauses, it might be using the Indexes.
Can anyone suggest some tuning tips?

Help tuning the query on NAST table .
I have the below query on NAST table which is performin very badly:
SELECT objky INTO TABLE i_objky
    FROM nast
    WHERE kappl = c_kappl           Â
    AND  ( ( kschl = c_kschl_zbax )Â
          OR ( kschl = c_kschl_zoem ) )
    AND  vstat = c_vstat_comp      Â
    AND  objtype = c_likp
     AND ( ( datvr EQ w_start_date AND
             uhrvr GE w_start_time ) OR
           ( datvr EQ w_end_date AND
             uhrvr LE w_end_time ) OR
           ( datvr GT w_start_date AND
             datvr LT w_end_date ) ).
Further there is already an index on KAPPL and KSCHL.

       Ashish kumarIf I understood your logic correctly - you are trying to select objects which have outputs processed within your date/time interval.
You can try to rewrite your select to force index 'A' usage as suggested by Christian, but it is not very helpful if you have too many records in NAST as in this case this index is not very selective and optimizer usually ignores it. Of course, you can ask your BASIS folks to tell you if you can use 'hint' addition in your select to force index usage as it depends on DB and some DBs require some work to be done on DB level to enable hints.
Other options could be
- try to provide a range (even if it is wide enough) for object key... it may really help as NAST contains too many records for different objects and this range may help with primary key usage.
- OR if you are interested in these 2 output types only - you can increase the speed of your select significally if you define a separate database table which you will update with these outputs (when they are just created in NAST) and your program (if it usually runs just once per your date.time range) will check the status of these outputs and then delete records from your table or just update them with "processed" status.
You can actually just create a copy of NAST table which is going to be updated when these outputs are processed (from corresponding processing program), so you will have records there with at least date, and then based on these records you can select actual date/time from NAST. It will be much faster... but it requires more design/coding. -
Please help me solve the query

i want a query or trigger on updating a single row all the row corresponding to it also gets updated example if i update a row with member f then its sponser e should also be updated and if sponser is is updatd then its sponser d should also be updated and if d is updated its spnser c should also be updated untill the last one through a single query
i have written the trigger
CREATE OR REPLACE TRIGGER points_updation
AFTER UPDATE
ON sponser_updation
FOR EACH ROW
DECLARE
v_username varchar2(10);
BEGIN
update sponser_updation
set
point=point+10
where
:new.member=:old.sponser;
END;
after updation of any row error message is comming
ORA-04098: trigger 'INVENT.SPONSER_UPDATION1' is invalid and failed re-validation
thanks & Regards,
anuj kumar singh!You can not insert, delete or update into this trigger type.
try this:
CREATE OR REPLACE TRIGGER points_updation BEFORE UPDATE ON sponser_updation FOR EACH ROW
BEGIN
if :new.member = :old.sponser then
:new.point:=:new.point+10;
end if;
END; -
Please help me to increase the performance of the query
Hello
I am not an oracle expert or developer and i have a problem to resolve.
Below is the query and explaiation plan and seeking the help to improve the performance of the query.
Our Analysis,
The query runs good,takes less one minute and fetches the results but during peak time it takes 8 minutes
Require anyone suggestion's to improve the query.
The query is generated from the Microsft dll so we dont have SQL code and require some help on tuning the tables.
If tuning the query improves then also fine please suggest for that also.

First-off, it appear that you are querying a view. I would redo the auery against the base table.
Next, look at a function-based index for the DATE column. Here are my notes:
http://www.dba-oracle.com/t_function_based_indexes.htm
http://www.dba-oracle.com/oracle_tips_index_scan_fbi_sql.htm
Also, make sure you are analyzed properly with dbms_stats:
http://www.dba-oracle.com/art_builder_dbms_stats.htm
And histograms, if appropriate:
http://www.dba-oracle.com/art_builder_histo.htm
Lasty, look at increasing hash_area_size or pga_aggregate_tagtet, depending on your table sizes:
http://www.dba-oracle.com/art_so_undocumented_pga_parameters.htm
Hope this helps. . . .

Please can you help me in Tuning this query..?
Hi ,
Please can you help me in re-structuring this query? .Details are given below.
I have 2 tables as shown below and data is like this.
Position
COD IND
AAA N
BBB N
CCC N
DDD Y
Distance
orig dest
AAA BBB
BBB CCC
AAA CCC
I need to create the records like this
start end
DDD AAA
DDD BBB
DDD CCC
The query which i am using now for this is
select p.code AS start,
P1.CODE AS end
from position p, position p1
where
P.CODE != P1.CODE
AND (P.ind = 'Y' or P1.IND = 'Y')
AND not exists
(select 1
from distance d
where (d.orig = p.code or d.dest = p.code)
and (d.orig = p1.code or d.dest = p1.code))
table is having above a crore record. so its taking a lot of time.
Please someone please help in tuning this query?
Thanks and regards,
ShabirLooks like you want this
select a.strt, b.ends from
(select p.code strt from position p where p.ind='Y') a,
(select p.code ends from position p where p.ind='N') b
where not exists (select 1 from distance d where d.orig=a.strt or d.dest=a.strt);
DDDÂ Â Â Â Â AAA
DDDÂ Â Â Â Â BBB
DDDÂ Â Â Â Â CCCYour query result is:
AAAÂ Â Â Â Â DDD
BBBÂ Â Â Â Â DDD
CCCÂ Â Â Â Â DDD
DDDÂ Â Â Â Â AAA
DDDÂ Â Â Â Â BBB
DDDÂ Â Â Â Â CCCYou should be more descriptive about what kind of result you want, so that people can get more interested in helping you. -
Help to rewrite the query --performance issue
Hi ,
Please help to rewrite the query since it's performance is not good.Especially second inline query(CASE statements are therein select caluse ..)is taking more cost.
