ExecuteQuery method of view object taking much time to execute

Hi All,
I am using a view object and execute the VO query using executeQuery method in VOImpl java.
But, problem is, it is taking long time to bring the results after executing the query after setting the parameters. Same query in TOAD gives 4 seconds. While executing using executeQuery method, it is taking 5 mins.
It is urgent issue. Please help me. Thanks.
Regards, Soorya

Hi Kali,
Thanks for your prompt response.
Yes. It has bind parameters. I have printed the statement before and after the executeQuery method
++VOImpl Code snippet++
setWhereClauseParams(params);
System.out.println("before executing query:Time:"+System.currentTimeMillis());
executeQuery();
System.out.println( "after executing query:Time:"+System.currentTimeMillis());
+++
I have removed some conditions in the query as it is business confidential. Please find the jdev log.

Query taking much time to execute

The following query is taking more than 4hrs to execute.
select l_extendedprice , count(l_extendedprice) from dbo.lineitem group by l_extendedprice
Cardinality of table : 6001215 ( > 6 million)
Index on l_extendedprice is there
ReadAheadLobThreshold = 500
Database version 7.7.06.09
I need to optimize this query. Kindly suggest way out.

Data Cache : 80296 KB
Ok, that's 8 Gigs for cache.
The index takes 16335 pages à 8 KB = 130.680 KB = 128 MB.
Fits completely into RAM - the same is true for the additional temp resultset.
So once the index has been read to cache I assume the query is a lot quicker than 4 hours.
6 Data Volumes
first 3 of size 51.200 KB
other 3 of size 1,048,576 KB
Well, that's not the smartest thing to do.
That way the larger volumes will get double the I/O requests which eventually saturates the I/O channel.
Yes looking at the cardinality of the table lots of I/O required but still more than 4 hrs is quite unrealistic. Some tuning is required.
We're not talking about the cardinality here - you want all the data.
We talk pages then.
And as we've seen, the table is not touched for this query.
Instead the smaller index is completely read in a index only strategy.
Loading 128MB from disk, creating temporary data in the same size and spilling out the information (and thereby reading the 128 MB temp size again) in 4 hours add up to ca. 384 MB/4 hours = 96 MB/hour = 1,6 MB/minute.
Not too good really - I suspect that the I/O system here is not the quickest one.
You may want to activate the time measurement and set the DB Analyzer interval to 120 secs.
Then activate Command and Resourcemonitor and look for statements taking longer than 10 minutes.
Now run your statement again and let us know the information from Command/Resourcemonitor and check for warnings in the DBanalyzer output.

Lars

How to build sql query for view object at run time

Hi,
I have a LOV on my form that is created from a view object.
View object is read-only and is created from a SQL query.
SQL query consists of few input parameters and table joins.
My scenario is such that if input parameters are passed, i have to join extra tables, otherwise, only one table can fetch the results I need.
Can anyone please suggest, how I can solve this? I want to build the query for view object at run time based on the values passed to input parameters.
Thanks
Srikanth Addanki

As I understand you want to change the query at run time.
If this is what you want, you can use setQuery Method then use executeQuery.

Owb job taking too much time to execute

While creating a job in OWB, I am using three tables,a joiner and an aggregator which are all joined through another joiner to load into the final table. The output is coming correct but the sql query generated is very complex having so many sub-queries. So, its taking so much time to execute. Pls help me in reducing the cost.
-KC

It depends on what kind of code it generates at each stage. The first step would be collect stats for all the tables used and check the SQL generated using EXPLAIN PLAN. See which sub-query or inline view creates the most cost.
Generate SQL at various stages and see if you can achieve the same with a different operator.
The other option would be passing HINTS to the tables selected.

Adding column is taking much time. How to avoid?

ALTER TABLE CONTACT_DETAIL
ADD (ISIMDSCONTACT_F NUMBER(1) DEFAULT 0 NOT NULL
,ISREACHCONTACT_F NUMBER(1) DEFAULT 0 NOT NULL
Is there any way that to speed up the execution time of the query?
It's more than 24 hrs completed after started running the above script.
I do not know why it is taking much time.
Size of the table is 30 MB.

To add a column the row directory of every record must be rewritten.
Obviously this will take time and produce redo.
Whenever something is slow the first question you need to answer is
'What is it waiting for?' You can do so by investigating by various v$ views.

Query taking much time Orace 9i

Hi,
**How can we tune the sql query in oracle 9i.**
The select query taking more than 1 and 30 min to throw the result.
Due to this,
We have created materialsed view on the select query and also we submitted a job to get Materilazed view refreshed daily in dba_jobs.
When we tried to retrive the data from Materilased view getting result very quickly.
But the job which we has been assisgned in Dbajobs taking equal time to complete, as the query use to take.
We feel since the job taking much time in the test Database and it may cause load if we move the same scripts in Production Environment.
Please suggest how to resolvethe issue and also how to tune the sql

I dunno, it looks like you are getting all the things that are null with an outer join, so won't that decide to full scan anyways? Plus the union means it will do it twice and do a distinct to get rid of dups - see how it does a union all and then sort unique. Somehow I have the feeling there might be a more trick way to do what you want, so maybe you should state exactly what you want in English.

Actually yesterday, we went to SM58 in R/3 side and executed that LUW for some other data sources. Now also we can do but we don't want to like that. Because we are expecting permanent soulution.
