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.

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.

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 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?
Ram

In which cases does String.intern() increase the performance?

I'm optimizing my program and I wonder when I should use the String.intern() method to increase my performance. Is there a downside of using the intern() method?

paul.miner wrote:
kajbj wrote:
I have once implemented a system where intern was called on all strings when they arrived from a socket, and all comparisons was done using == after that. The reason was actually performance since we had to compare lots and lots of strings often. There is however a drawback with it. calling intern() when you have many strings in the pool is very slow (I would guess that it was linear time). You it's now always that you can improve performance by calling intern and comparing with ==Good point.
I think if I was in this position though, I'd create my own interned string pool instead of cluttering the one in String.We tried that as well. We pretty much did everything we could think of to reduce memory footprint while gaining execution time. Startup time was not of importance so it was not a problem that it took an hour to start the system.

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.

Hi,
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. . . .
