Increase the performance of query

Hi,
I have a procedure where cursor runs query in loop. There are 50,000 records and query is run 50,000 times and hence it decreases CPU performace and 96% of database time is consumed because of this query.
Its on Oracle 8i.
What can be done to make sure query runs faster as currently it takes 4 hours?
Thanks,
Calci

2. If your answer is NO for the first question, i would say you must think again.
3. Check if you are using bind variable in the SQL used in the loop to reduce hard parse.

How to increase the performance of an insert query?

Hi,
I am using oracle database for our application where we executes one insert query and need the performance of 300 insert queries to be executed per second.
As of now we are getting only 30/sec.We are not knowing how to tune the database for getting this performance.
we are doing all this though C programming under both linux and solaris environment.
Can u guide me in this issue.

vamsi krishna

Performance tuning issue is not something you can get a straight forward answer for.
You need to look at various aspects of the system to get close to or increase the performance of your application. Tuning just the database might not give you want you want.
So, you need to look at the Application codes, Mermory, Disk IO, etc. Have a look at the Performance Tuning Guide from the Oracle Documentation Library for your Oracle Release and Operating System

Increase the Performance of a package while execution

Hi,
i am using oracle 9i and linux..
in my pl/sql if i executed a particular package it will take 5 min.
please explain how to increase the performance of the package
how to extract the query from the package and
how to build an explain plan..
and how to tune the query
Regards

If you wanna test pl/sql, sql profiler is a good way to test.
You can always use 10046 event to trace the queries in the package. Take their explain plan and see if there is any room for tune.

How to increase the performance of a domain index?

Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production
I am using a dynamic query which uses a domain index for a clob column. The table has 1021487 records. How can i increase the performance of a select query based on this table? This is the only part where my application gets slowed down.
The query is
SELECT :search_id, 100, :item_type, c.search_college, c.search_colname, TRUNC(dbms_random.value(900000000000, 999999999999)) rand, COUNT(1), c.college_rating, min(DECODE(c.search_postcode, NULL, 99999, NULL)) search_distance FROM w_search_text c WHERE c.search_course_type is not null
and (contains(c.search_text,:search_text,2) > 0)
AND c.search_item_type = :item_bind
GROUP BY c.search_college, c.search_colname, c.college_rating
ORDER BY c.search_college
here c.search_text is the domain indexed column?
Is there a way to tune it?
Ram

Here c.search_text is the clob column.
i am using 4 bind variables and they are search id : 123456
item_type : O
search_text : French
item_bind : Z
I tried explain plan and here are the results
Plan
SELECT STATEMENT ALL_ROWSCost: 5 Bytes: 38,280 Cardinality: 264
     3 SORT GROUP BY Cost: 5 Bytes: 38,280 Cardinality: 264
          2 TABLE ACCESS BY INDEX ROWID TABLE HOT_ADMIN.W_SEARCH_TEXT_LIVE2 Cost: 4 Bytes: 38,280 Cardinality: 264
               1 DOMAIN INDEX INDEX (DOMAIN) HOT_ADMIN.W_SRCH_TXT_IDX2 Cost: 4
Its using the domain index, But the column is highly fed up with data...so ithink that may be the reason.Is there any HINTS in particular to tune domain indexes?

Increase the performance of fileadapter

Hi,
can any body tell me how to increase the performance of the FILEADAPTER & DBADAPTER?
Regards,
Krishna.

As Anirudh has correctly stated you should upgrade if possible. In 10.1.3.1 the DB adapter had many issues, plus 10.1.3.1 was released 3 years ago so very old version.
I would recommend upgrading or starting on 11.1.1.2 as there have been many improvement in the file and db adapters to manage large payloads. In 10.1.3.x you have limitations of 1MB in size before you need to start tuning or doing some advanced configuration.
11g is the way forward, implemented using Oracle strategic application.

If yes, then how.
What are the key factor should we consider while design of query in regards of Query performance.
I shall ne thankful to you for this.

There will not be any significance perofrmance issue for Colouring the rows or columns...
But there are various performance parameters which should be looked into while designing a query...
Hope this PPT helps you.
