Merge Query Taking Long time !!!

Hi all,
Im using loading type update/insert in one of my mappings.
mapping usually takes 3-4 mins to complete.
Suddenly It has taken 1 Hr to complete. If I take the select query from the mapping, its running fast and completes in 2 mins.
I Checked the source data count, Indexes in the source columns. Everything is the same
Mapping level, I didnt do any changes. Can anyone suggest what would be possible reason???
Thanks and Regards

Lots of things come into play when you're tuning a query.
An (unformatted) execution plan isn't enough.
Tuning takes time and understanding how (a lot of) things work, there is no ASAP in the world of tuning.
Please post other important details, like your database version, optimizer settings, how/when are table statistics gathered etc.
So, read the following informative threads (and please take your time, this really is important stuff), and adust your thread as needed.
That way you'll have a bigger chance of getting help that makes sense...
Your DBA should/ought to be able to help you in this as well.

I have some suggestions. But first, you realize that you have some redundant indexes, right? You have an index on account(account_name) and also account(account_name, account_id), and also account_history(invoice_id) and account_history(invoice_id, adjustment_id). No matter, I will suggest some new composite indexes.
Also, you do not need two lines for these conditions:
and round(a.account_balance, 2) > 0
AND a.account_balance > 0
You can just use: and a.account_balance >= 0.005
So the formatted query isselect a.account_id,
       round(a.account_balance, 2) account_balance,
       nvl(ah.invoice_id, ah.adjustment_id) transaction_id,
       to_char(ah.effective_start_date, 'DD-MON-YYYY') transaction_date,
       to_char(nvl(i.payment_due_date, to_date('30-12-9999', 'dd-mm-yyyy')),
               'DD-MON-YYYY') due_date,
       ah.current_balance - ah.previous_balance amount,
       decode(ah.invoice_id, null, 'A', 'I') transaction_type
from account a, account_history ah, invoice i
where a.account_id = ah.account_id
   and a.account_type_id = 1000002
   and (ah.invoice_id is not null or ah.adjustment_id is not null)
   and ah.CURRENT_BALANCE > ah.previous_balance
   and ah.invoice_id = i.invoice_id(+)
   AND a.account_balance >= .005
order by a.account_id, ah.effective_start_date desc;You will probably want to select:
1. From ACCOUNT first (your smaller table), for which you supply a literal on account_type_id. That should limit the accounts retrieved from ACCOUNT_HISTORY
2. From ACCOUNT_HISTORY. We want to limit the records as much as possible on this table because of the outer join.
3. INVOICE we want to access last because it seems to be least restricted, it is the biggest, and it has the outer join condition so it will manufacture rows to match as many rows as come back from account_history.
Try the query above after creating the following composite indexes. The order of the columns is important:create index account_composite_i on account(account_type_id, account_balance, account_id);
create index acct_history_comp_i on account_history(account_id, invoice_id, adjustment_id, current_balance, previous_balance, effective_start_date);
create index invoice_composite_i on invoice(invoice_id, payment_due_date);All the columns used in the where clause will be indexed, in a logical order suited to the needs of the query. Plus each selected column is indexed as well so that we should not need to touch the tables at all to satisfy the query.
Try the query after creating these indexes.
A final suggestion is to try larger sort and hash area sizes and a manual workarea policy.alter session set workarea_size_policy = manual;
alter session set sort_area_size = 2147483647;
alter session set hash_area_size = 2147483647;

CDHDR table query taking long time

Hi all,
Select query from CDHDR table is taking long time,in where condition i am giving OBJECTCLASS = 'MAT_FULL' udate = sy-datum and langu = 'EN'.
any suggestion to improve the performance.i want to select all the article which got changed on current date
regards
shibu

This will always be slow for large data volumes, since CDHDR is designed for quick access by object ID (in this case material number), not by date.
I'm afraid you would need to introduce a secondary index on OBJECTCLAS and UDATE, if that query is crucial enough to warrant the additional disk space and processing time taken by the new index.

where the rm_personquestion table is having 45 million rows and winning_id_cleanup is having 1 million rows.
please tell me how to tune this query?

Query taking long time

Hi
I have a query in which, its a 3 table join but takes a long time to execute. I had checked with plan table.. it shows one of the table is FULL ACCESS.
I have 2 clarifications.
1. Will the status checking as NULL - (it shouldn't use index)
2. Is the case statements are recommended for queries.
Query
Select .........

AND

AND

Hi,
There is nothing wrong in having a full table access. When you do the explain plan please check for which table costs you the maximun. try to work on that table.
To tune the performance of your query you can try either indexing or parallel access.
the syntax for parallel index is
/*+ PARALLEL("TBL_NM",100) */(any number)...
for index please use the index name of the table you want to index..

LINQ query taking long time

Following query i write it returns me 1400 records. and below line taking much time.
1.5 second taken by
count = quer != null ? quer.Count() : 0;
and 2 sec taken by
candidateList = quer.Skip((pageIndex - 1) * pageSize).Take(pageSize).ToList();
Please suggest.

Hi Jon,
In SharePoint, I suggest you use CAML Query. If you use Linq, the performance won't be gurantteed.
For the first query, you can use SPQury.Count to achieve it, for the second query, you can build a proper CAML to filter the data.
Here are some detailed articles for your reference:

QUERY taking longer time than usual

Hello Gurus,
The query below used to take 5-10 minutes depending on the resource availability, but this time it is taking 4-5 hrs to complete this transaction.
INSERT /*+ APPEND */ INTO TAG_STAGING
SELECT /*+ INDEX(A,ALL_tags_INDX1) */
DISTINCT TRIM (serial) serial_num,
TRIM (COMPANY_numBER) COMPANY_NUM,
TRIM (PERSON_id) PERSON_id
FROM ALL_tags@DWDB_link a
WHERE serviceS IN (SELECT /*+ INDEX(B,service_CODES_INDX2) */
services
FROM service_CODES b
WHERE srvc_cd = 'R')
AND (ORDERDATE_date BETWEEN TO_DATE ('01-JAN-2007','dd-mon-yyyy')
AND TO_DATE ('31-DEC-2007','dd-mon-yyyy'))
AND ( (TRIM (status_1) IS NULL)
OR (TRIM (status_1) = 'R')
AND (TRIM (status_2) = 'R' OR TRIM (status_2) IS NULL)
TAG_STAGING table is empty with primary key on the three given columns
ALL_tags@DWDB_link table has about 100M rows
Ideally the query should fetch about 4M rows.
Could any one please give me an idea as to how to proceed to quicken the process.
Thanks in advance
Thanks,

First I'd check the explain plan to make sure that it makes sense. Perhaps an index was dropped or perhaps the stats are wrong for some reason.
If the explain plan looks good then I'd trace it and see where the time is being spent.

SELECT query taking long time

Hi All,
I am trying to run one SELECT statement which uses 6 tables. That query generally take 25-30 minutes to generate output.
Today it is running from more than 2 hours. I have checked there are no locks on those tables and no other process is using them.
What else I should check in order to figure out why my SELECT statement is taking time?
Any help will be much appreciated.
Thanks!

Please let me know if you still want me to provide all the information mentioned in the link.Yes, please.
Before you can even start optimizing, it should be clear what parts of the query are running slow.
The links contains the steps to take regarding how to identify the things that make the query run slow.
Ideally you post a trace/tkprof report with wait events, it'll show on what time is being spent, give an execution plan and a database version all in once...
Today it is running from more than 2 hours. I have checked there are no locks on those tables and no other process is using them.Well, something must have changed.
And you must indentify what exactly has changed, but it's a broad range you have to check:
- it could be outdated table statistics
- it could be data growth or skewness that makes Optimizer choose a wrong plan all of a sudden
- it could be a table that got modified with some bad index
- it could be ...
So, by posting the information in the link, you'll leave less room for guesses from us, so you'll get an explanation that makes sense faster or, while investigating by following the steps in the link, you'll get the explanation yourself.

First select - mixed order of fields. Response time: 82.155 microseconds for 39380 records selected.
Second select - fields in the order of the table. Response time: 81.061 microseconds for the same 39380 records selected.
Then I changed the order of SELECT statements. I have put first the select with ordered fields, and second - select with mixed order of fields. The runtimes were the following:
Ordered fields - 82.649 microseconds
Mixed order of fields - 80.270 microseconds.
So I'm going to change the Wiki page in order to avoid in future advices that make no sense.

Select Query taking long time to run second time

Hi All,
I have Oracle 11gR1 in windows server 2008 R2 .
I have some tables with 10 million records . When i run the select query for those tables first time it gives me result in 15 seconds but if i am running the same script second time from the same session I am getting the result in 15 minutes to complete ..
Why it is happening? What may be the solution for this ?
Thanks & Regards,

Hi Mohamed,
I just saw that both the times for the same query execution plan is different ..
here are the details :

Query taking long time in oracle 10g

I have a query which runs in 1 minute in oracle 8 but it takes 2 hours in oracle 10. The query has couple of sub queries to select the max effective date as wee as current effective sequence. I checked the parameters and their values are as follows. I want to know whether any values can be increased to make it run faster. Also I did not find the parameter unnestsubquery, I think it should be set to FALSE but did not find the value when I did select * from v$parameter. Is it set to false value by default or should i explicitly declare it. Thanks
