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?

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.
Regards,
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

How to increase the performance of Applet loading in IE ?

Hi All,
I have a Applet named "editlivejava.jar" which is around 2.17 mb in Size, when ever i opened the browser for render the applet it is taking time to load.
Is there any way to increase the perfornamce. I heard that it should be some thing related to the client(PC) JVM heap size. Being the case is there any recommandations available so that we can apply the seetings to the JVM? Also would like to know if the same Jar is available in the JVM temporary files , will it download the JAR again to the PC or will it try to run the same locally available?. If JVM heap size matters , could anybody suggest me how should i manipulate the min and max for a PC which has lets say 1 GB of RAM.
Form the Java console i could see lots of JRE versions present. How do i know which JRE should i need to change the memory.
Help me out and thanks in advance.

Also tell me how to see the indexes for the tables?
IF NOT i_aufk IS INITIAL.
    SELECT aufnr      "Order number
            budat      "Posting date
    INTO TABLE i_afru

    FOR ALL ENTRIES IN i_aufk
    WHERE aufnr = i_aufk-aufnr.
    IF sy-subrc EQ 0.
      SORT i_aufk BY aufnr.
please do reply.thanks

Hi,
change the source code as:
IF NOT *i_aufk[]* IS INITIAL.
SELECT aufnr "Order number
budat "Posting date
INTO TABLE i_afru
FROM afru "Order Confirmations
FOR ALL ENTRIES IN i_aufk
WHERE aufnr = i_aufk-aufnr.

How to increase the performance with the case structure?

Hiii, All
I want to stop the looping into my vi, which is occuring because of Case structure, as i ve shown in the figure, i am checking for the trigger, either it is Manual or it is Auto, if auto i am going inside the case and checking the loop of either Auto trigger is for Analog values or for digital values, if it is for analog valus, i am checking the set point that, either P.V. has cross the setpoint or not? if it is then i am starting to write the file and the control comes out again to check the Start trigger again, either it is Auto or manual? and because of these contonuous loops inside the while loop, my other while loops inside the vi, decrease the performance mean they are slowing down also with the current while loop, so i think solution is to stopping these nested loops, but what should i do to stop these nested loops? please suggest something.
Thanks in Advance,
Nishant

You can consider multithreading the single loop and using a synchronization resource to communicate between threads. You should also consider cutting down on the global variable dependancies which makes the code hard to follow.

How to Increase the performance in loading a page

Hi
I am developing E-mail application. In that we r using JSP for view. In E-mail application the compose page will be loading with little bit time. In this compose JSP, just To, CC,BCC, and Subject textboxes are using for Content TextArea using. In this page "To" has the link, when i click on "To" link contacts(Addresses) will be open with in the same page with another JSP throw Ajax. Means, In Compose page we r calling the contact's JSP page throw Ajax. In this case, Initially when i click on Compose page these contacts will be loading. that's why it takes time when i open the compose page. Is there any solutions to improve the performance. (for loading the page with less time) ??
Thanks
Adusumalli

Cache you contacts data for example. there are plenty of cache solutions for JSP. Check out [Cache taglibs|http://www.servletsuite.com/jsp3.htm] in Coldtags suite for example

Do you have an idea how to improve the performance ?

Hi All,
Greeting,
I'm doing SEM IP. Regarding the performance, do you have some thought about this ?
So I have planning report for project report . As we know, if we forecast against project, means the date itself is the life of the project itself.
It means it could be more than 10 years (forecast period) and 10 years (actual period). Currently I segregate between actual and forecast into different info cube .
But the performance of the planning report is slow now. Do you have an idea about this how to increase the performance. The performance I mentioned here is when we're going to the report (after putting in the value in the selection screen).
The other question, at this moment, I have a multiprovider than this multi provider consist 2 info cubes ( actual and forecast ). Than my aggregation is sitting on top of that multi-provider .
My question whether that's approach correct or not ? Or do we have to create 1 aggregate (only for forecast), than I have multi-provider consisting forecasting aggregation and actual cube .
than my query will sit on top of that multi-provider ?
Which one is better ??
Thanks a lot all,
really need your help,

Hi,
For the performance tuning, you can consider any of the following three methods,
1. Indices
With an increasing number of data records in the InfoCube, not only the load but also the query performance can be reduced. This is attributed to the increasing demands on the system for maintaining indexes. The indexes that are created in the fact table for each dimension allow you to easily find and select the data.
2. Partitioning
By using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. Thanks to this separation, performance is increased when reporting, or also when deleting data from the InfoCube.
3. Aggregates
Aggregates make it possible to access InfoCube data quickly in Reporting. Aggregates serve, in a similar way to database indexes, to improve performance.
4. Compressing the Infocube
Infocube compression means aggregation of the data ignoring the request idu2019s. After compression, the system need not perform aggregation using the request ID every time you execute a query.
And I feel that as per your scenario, you need to do first compress the data based on user requirements and have only the required data in the infocube.
And for the approach regarding the Aggregation level design, choosing between the two approaches depends on the user requirements. For example,
If you have aggregation level created on top of multiprovider containing actual and forecast cube, in your report (created on top of aggregation level) you can view the key figure values present in both the cubes, which is not possible in the other approach.
So this approach is suited if your requirement is to view the records from both the cubes in your report (Comparing planning and actual values).
The second approach is used if your requirement is only to report on planning forecast cube.
Hopes this solves your issue.

Balajee

How to improve the performance of General information in MSS

HI,
We are facing with critical performance issue in General information screen of MSS.
For one employee number of subordinates are more than 3500 and because of this no of database hits for fetching all the records are more than 20,000 and each database hit is taking some time and overall time for fetching all the records is around 2 minutes which is not acceptable.
so we want to cut down the number of hierarchy levels shown to the manager or by keeping the same number of levels how to increase the performance .
Any inputs will be highly appreciated and rewarded with points for sure
Bala Duvvuri

Hi,
We have problem in performance because when we call General information screen for managers in MSS it reads the data from HRP1001 and if manager is having more data then it will take time.
we rectified this problem by creating an index that caches all the users who have more number of objects .
we created a job that creates index and execute that every day

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.
