Needs ur help in tuning a sql
Hi,
I have a partioned table.I am spooling output of an sql which joins the partioned table and another referece table of minimal data.
each partion except 3 contains 5 milllion records on average
othere 3 partitions has 6.6 million records (each one).
The sql takes 3 mins if it is triggered against the partions with 5 million but
the same sql is taing 8 hrs if it is triggered against the partion with 6.5 million.
Please help me how can avoid this performace issue
Below are IO statistics for the two cases
(partion with 6.5 million)
BLOCK_GETS=9
CONSISTENT_GETS=89533761
PHYSICAL_READS=15746
(partion with 5.0 million)
BLOCK_GETS=8
CONSISTENT_GETS=1215131
PHYSICAL_READS=28848
Hi,
post the select for the 2 SQL's and the EXPLAIN for each.

Hi
I have a query which will read one fact table and 4 dimension table.fact table contains millions of records
Can u suggest me how can i tune my query which uses the fact table to get the best performance.Which version of the database are you using? Have you enabled Star Transformation? What does the explain plan look like? Is this intended for building a materilaized view or as the basis for running an ad hoc report?
We created bit map indexes on the joining columns.bitmap indexes or bitmap-join indexes?

i have two questions :
-1 The problem in tables XSVPATIENTRECORD and XSVRECPERXREF so how can i speed this query either by rewriting it or indexs?
-2 is my system i-o is slow ?
Best wishes

it did not work with dynamic samplying. I am posting here trace 10053 output for the correct plan and wrong plan choosed but the optimizer i need soome one to help me in understanding why the optimizer is choosing wrong join order.

Hi,
I need a help in writing an SQL query . I am actually confused how to write a query. Below is the scenario.
CREATE TABLE demand_tmp
( item_id NUMBER,
org_id NUMBER,
order_line_id NUMBER,
quantity NUMBER,
order_type NUMBER
CREATE TABLE order_tmp
( item_id NUMBER,
org_id NUMBER,
order_line_id NUMBER,
open_flag VARCHAR2(10)
INSERT INTO demand_tmp
SELECT 12438,82,821,100,30 FROM dual;
INSERT INTO demand_tmp
SELECT 12438,82,849,350,30 FROM dual;
INSERT INTO demand_tmp
SELECT 12438,82,NULL,150,29 FROM dual;
INSERT INTO demand_tmp
SELECT 12438,82,0,50,-1 FROM dual;
INSERT INTO order_tmp
SELECT 12438,82,821,'Y' FROM dual;
INSERT INTO order_tmp
SELECT 12438,82,849,'N' FROM dual;
Demand_tmp:
Item_id org_id order_line_id quantity order_type
12438 82 821 100 30
12438 82 849 350 30
12438 82 NULL 150 29
12438 82 0 50 -1
Order_tmp :
Item_id org_id order_line_id open_flag
12438 82 821 Y
12438 82 849 N I need to fetch the records from demand_tmp table whose order_line_id is present in order_tmp and having open_flag as 'Y' or if order_type in demand_tmp table is 29.
The below query will give the records whose order line id is present in order_tmp. But, If i need records which are having order_type=29 the below query wont return any records as order_line_id is NULL. If I place outer join I will get other records also (In this example order_type -1 records) . Please help me how can we write a query for this. Expected o/p is below.
Query :
Select item_id,org_id,order_line_id,quantity,order_type,open_flag
from demand_tmp dt , order_tmp ot
where dt.order_line_id = ot.order_line_id
AND dt.item_id=ot.item_id
AND dt.org_id = ot.org_id
AND ot.open_flag = 'Y';
Expected Output :
item_id org_id order_line_id quantity order_type open_flag
12438 82 821 100 30 Y
12438 82 NULL 150 29 NULL Thanks in advance,
Rakesh

Edited by: Venkat Rakesh on Oct 7, 2012 8:39 PMHi Rakesh,
the query is not working as you would like ( but IS working as expected ) since your trying to compare null to another value.
Comparing null always results in FALSE, also if you compare null to null. This is because null means undefined.
select 1 from dual where null=null results in no data found.
I would suggest using a non natural key to join the tables.
For example include a column ID in the master table which is filled with a sequence and include that field as a foreign key in the detail table.
This way you can easily join master and detail on ID = ID, and you don't have to worry about null values in this column since it's always filled with data.
Regards,
Bas
btw, using the INNER JOIN and OUTER JOIN syntax in your SQL makes it better readable, since you're separating join conditions from the where clause, just a tip ;) -
Plz help me to understand sql trace

nicHi,
i did the homework, but some how i dont seem to understand what oracle is doing behind
esp with hints like
select /*+ leading(v1 v2) use_nl_with_index(v2) */ count(v1.val)
/*+ no_parallel(t) no_parallel_index(t) dbms_stats
cursor_sharing_exact use_weak_name_resl dynamic_sampling(0) no_monitoring
substrb(dump(min("XXX"),16,0,32),1,120),
substrb(dump(max("XXX"),16,0,32),1,120),i havent used this things any where in my program, but still they are used,
so i got confused, can you throw some light on this issue,
regards

Need help in rewriting a sql query
Can any one please tell me if there is any utility that can help me correcting the sql I have I need to tune the query as its taking lot of time. I want to use some tool that will help me re-formating the query.
Any help in this regard will be highly appreciated.If you think that Oracle SQL Tuning Tools like SQL Tuning Advisor and SQL Access Advisor are not helping.
You might look into thrid party tools like Quest- SQL Navigator and TOAD.
But I don't advise this based on the following:
Re: Oracle Third Party Tools and Oracle Database
Oracle have enough tools of its own to satisfy the various needs.

Need help in tuning a procedure
DECLARE
CURSOR Cur_sub_rp IS

INSERT INTO SUB_PHN_1 VALUES VALUES_TAB(i);
commit;
END;
The tables used here has 9 million records each.
The total process takes around 19 minutes.
Need your help in optimizing the process.i have tried using
Create table as SELECT A.SUB_ACCOUNT, B.PH_basic_srv,B.PH_Salesman,A.SUB_SSN

B
WHERE A.SUB_ACCOUNT = B.PH_ACCOUNT (+)
AND A.MONTH_ID = B.MONTH_ID (+);But still taking long time(apprx 15 min).
so used this...
help me in tuning the query in either of this.

Need help in Report From SQL Query
Hi All,
I am facing a problem with a report. I need your help.
I am creating a Report From SQL Query (Portal) with some arguments passed at runtime. I am able to view the output, if the query returns few rows ( arount 1000 rows). But for some inputs it needs to generate >15000 records, at this point the page is getting time out (i think!) and showing error page. I am able to execute query from the SQL Plus console ot using TOAD editor. Here the query is not taking more that 2 mins time to show the result.
If i am executing from Portal i observed that, once i give the appropriate input and hit submit button a new oracle process is getting created for the query on UNIX (I am usign "TOP" command to check processes). The browser page will be shown error page after 5 minutes (i am assuming session time out!) , but on the backend the process will be executed for more than 30 mins.
I tried also increase the page time out in httpd.conf, but no use.
The data returned as a result of the query is sized more than 10 MB. Is caching this much data is possible by the browser page? is the returned data is creating any problem here.
Please help me to find appropriate reasone for the failure?user602513 wrote:

There could be a variety of reasons for the delayed processing of this report. That includes parameter settings for that page, cache settings, network configurations, etc.
- explore best optimization for your query;
- evaluate portal for best performance configuration; you may follow this note (Doc ID: *438794.1* ) for ideas;
- third: for that particular page carrying that report, you can use caching wisely. browser cache is neither decent for large files, nor practical. instead, explore the page cache settings that portal provides.
- also look for various log files (application.log and apache logs) if you are getting any warnings reflecting on some kind of processing halt.
- and last but not the least: if you happen to bring up a portal report with more than 10000 rows for display then think about the usage of the report. Evaluate whether that report is good/useful for anything?

Need help in installation of SQL Developer in Win7
Dear Frens,
I got a task to validate the SQL developer(64 bit version) in Win7 environment. I followed the advice in this form and installed the 64 bit JDK first.
It can be verified:
C:\>java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
Then SQL developer asked for the path of java.exe for the first time, and after configuring it to the correct path, I found it had problems creating the connection to the database when I tried to click database connection button. Please be noted, I do not have the win admin right for the PC.
The error messages are listed below. Need some help from you guys.

We have to inverstigate about a reporting solution where things are getting slow (may be material, database design, network matters).
I have red a lot in MSDN and some books about performance tuning on SQL Server 2008 R2 (or other) but frankly, I feel a little lost in all that stuff
I'am looking for practical steps in order to do the tuning. Someone had like a recipe for that : a success story...
My (brain storm) Methodology should follow these steps:
Resource bottlenecks: CPU, memory, and I/O bottlenecks
tempdb bottlenecks
A slow-running user query : Missing indexes, statistics,...
Use performance counters : there are many, can one give us the list of the most important
how to do fine tuning about SQL Server configuration
SSRS, SSIS configuration ?
And do the recommandations.
Thanks

Edsger W. DijkstraHello,
There is no clear defined step which can be categorized as step by step to performance tuning.Your first goal is to find out cause or drill down to factor causing slowness of SQL server it can be poorly written query ,missing indexes,outdated stats.RAM crunch
CPU crunch so on and so forth.
I generally refer to below doc for SQL server tuning
http://technet.microsoft.com/en-us/library/dd672789(v=sql.100).aspx
For SSIS tuning i refer below doc.

Need Help in correcting the sql statement
H Experts,
I am not if I can post this query in this section, but as I am executing this statement on repository DB , I assumed to post here.
I have a requirement to calculate the database sizes from the tables in repository.
table 1 : MGMT$DB_TABLESPACES_ALL : has the information on all the tablespace information from each database. and it has information of all the databases.
table 2: MGMT$DB_REDOLOGS_ALL : has the information on all the redolog files information from each database. and it has information of all the databases.
Now to calculate the size of each database , we need to collect the sizes from both tables and then need to add.
below is the sql i prepared and sql didn't return and systax error , but the final output is completely wrong. Seems like its multiplying the data somewhere and getting the wrong information.

Need to convert DTS packages to SQL Server 2012 environment.
Hi Friends,
As Part of the Project Requirement,we need to convert DTS packages to SQL Server 2012 environment.
Please sugest me best approach.
ThanksBest approach is to re-design the packages in SSIS 2012 directy if it is feasible. Because most of the DTS feaures are discontinued and also you will have to clean up all errors that you are going to get after migration.
Discontinued Integration Services Functionality in SQL Server 2012
Otherwise you need to migrate it first to 2008R2 and then 2012 version.
Below ones would be helpful for you:
Migrate DTS packages to SSIS (SSIS2008R2)
Support of DTS packages in 2008 R2
Known DTS Package Migration Issues
Cheers,
Vaibhav Chaudhari
