Query Performance is low with single function
Hi all,
I neetd to calculate the net salary of around 2000 employees.i use function to get it from payrun tables
i.e..
CREATE OR REPLACE function xxri_total_net(p_date IN VARCHAR2,p_empno IN NUMBER)
return number
as
v_earn number;
v_ded number;
begin
select nvl(sum(result_value),0)
into
v_earn from xxgod_soe_test where employee_number=p_empno
and base_classification_name='Earnings' and
to_char(date_earned,'MON-YYYY')=p_date and base_name='Pay Value';
select nvl(sum(result_value),0)
into v_ded from xxgod_soe_test where employee_number=p_empno
and base_classification_name like '%Deductions%' and
to_char(date_earned,'MON-YYYY')=p_date and base_name='Pay Value';
return v_earn-v_ded;
end;
It works fine with 10 sec as execution time,
but when i add it to my reports query it goes slow..
i m adding it as column,
xri_total_net(TO_CHAR(pAaV.effective_date,'MON-YYYY'),papf.employee_number) Net_Salary,
i even tried xri_total_net(TO_CHAR(:p_start_date,'MON-YYYY'),papf.employee_number) Net_Salary,
Kindly help me out to reduce the execution time.
Thanks,
Techie.
Okay, this is unfinished, as I do not know your data structure, and I have only filled in the earn in-line view, but I am trying to give you a starter for ten so you can finish it off on the same logic...
Final caveat - without knowing the structure I do not know if you will always have results in the in-line views, you may have to re-arrange further if there are cases without earnings and deductions but you still want to see the results....

Two button with single function
I want to create two buttons for single function and one button for one function. For example, I click button1, the screen will show "clicked1"
If I clicked button2, the screen will show "clicked2". If I click button1 and then click button2, it will show "two button are clicked". However, it does not work in two button with single function. What is the problem? Here is the code.
import flash.display.MovieClip;
import flash.events.MouseEvent;
var button1:MovieClip=new Button1();
button1.x=200;
button1.y=200;
addChild(button1);
var button2:MovieClip=new Button2();
button2.x=300;
button2.y=250;
addChild(button2);
button1.addEventListener(MouseEvent.CLICK, onClick);
button2.addEventListener(MouseEvent.CLICK, onClick2);
var isClicked:Boolean;
var isClicked1:Boolean;
function onClick(evt:MouseEvent):void{
isClicked=true;
trace("clicked1");
function onClick2(evt:MouseEvent):void{
isClicked1=true;
trace("clicked2");
if (isClicked&&isClicked1){
trace("two buttons are clicked");It works but I want the screen only shows the "isClicked" only when I click button1. But now when I click button1, "isClicked" and "two buttons are clicked" show at the same time.
import flash.display.MovieClip;
import flash.events.MouseEvent;
var button1:MovieClip=new Button1();
button1.x=200;

Query performance improvement using pipelined table function
Hi,
I have got two select queries one is like...
select * from table
another is using pielined table function
select *
from table(pipelined_function(cursor(select * from table)))
which query will return result set more faster????????
suggest methods for retrieving dataset more faster (using pipelined table function) than a normal select query.
rgds
somyCompare the performance between these solutions:
create table big as select * from all_objects;
First test the performance of a normal select statement:
begin
for r in (select * from big) loop
null;
end loop;
end;
/Second a pipelined function:
create type rc_vars as object
(OWNER VARCHAR2(30)
,OBJECT_NAME VARCHAR2(30));
create or replace type rc_vars_table as table of rc_vars ;
create or replace
function rc_get_vars
return rc_vars_table
pipelined
as
cursor c_aobj
is
select owner, object_name
from big;
l_aobj c_aobj%rowtype;
begin
for r_aobj in c_aobj loop
pipe row(rc_vars(r_aobj.owner,r_aobj.object_name));
end loop;
return;
end;
/Test the performance of the pipelined function:
begin
for r in (select * from table(rc_get_vars)) loop
null;
end loop;
end;
/On my system the simple select-statement is 20 times faster.
Correction: It is 10 times faster, not 20.

How the performance will increase with pipelined function.
Respects all,
Can u please help to explain one example regarding which i have mentioned in the subject line.
ThanksHi,
pipelined functions don't "increase performance".
1) This is an entirely wrong way to think about Oracle features. There are no Oracle features that automatically "increase performance", like some sort of a "turbo" button (not even partitioning! not even indexes!). Most of the features can work both ways -- when used appropriately, they improve performance, when not, they can cripple it.
2) Pipelined functions are not about performance. They simply provide a way for you to SELECT from a PL/SQL function (which otherwise is impossible to do). Not only you can generate sets of values this way, but also you can join it with other tables/views, that can be very convenient. Pipelined functions can also be very convenient for generating formatted text reports they allow you to bypass limitations of long/lob data types). But none of this has to do with performance.
3) Pipelined functions are inevitably associated with row-by-row processing (because there is no way to pipe a set of rows at once). So when the choice is between returning a refcursor (from which you can do a bulk fetch), and using a pipelined function, from which you'll be returning rows one by one, and none of items listed in 2) applies, then chances are that pipelined function is going to be slower.
So whoever claimed that "pipelined functions increase performance", either he/she is incompetent, or you took his/her words out of the context or misintepreted them.

Performance Routing (PfR) with single router, dual ISP and load balancing
It looks like PfR can do this but I have only found information about this feature which will start using ISP2 once ISP1 reaches 75% usage. But this is not load balancing.
Can we accomplish load balancing utilizing a single router with dual ISPs using this PfR feature?
Or do we have to use another feature?

I'm rusty using OER/PfR, but I recall it could load balance two links on same router. The issue, I also recall, if doing BGP, OER/PfR has to detect a load imbalance, and there's a certain difference allowance, and OER/PfR takes some time to decide, so depending on actual traffic, it might not be obvious it's working. If doing BGP, there's a hidden command (which I don't recall is) that will load balance the two links on the same router; then you use OER/PfR to dynamically refine the balance load. -
Oracle Query Performance While calling a function in a View
Hi,
We have a performance issue in one of our Oracle queries.
Here is the scenario
We use a hard coded value (which is the maximum value from a table) in couple of DECODE statements in our query. We would like to remove this hard coded value from the query. So we wrote a function which will return a maximum value from the table. Now when we execute the query after replacing the hard coded value with the function, this function is called four times which hampers the query performance.
Pl find below the DECODE statements in the query. This query is part of a main VIEW.
Using Hardcoded values
=================
DECODE(pro_risk_weighted_ctrl_scr, 10, 9.9, pro_risk_weighted_ctrl_scr)
DECODE(pro_risk_score, 46619750, 46619749, pro_risk_score)
Using Functions
============
DECODE (pro_risk_weighted_ctrl_scr, rprowbproc.fn_max_rcsa_range_values ('CSR'), rprowbproc.fn_max_rcsa_range_values('CSR')- 0.1, pro_risk_weighted_ctrl_scr)
DECODE (pro_risk_score, rprowbproc.fn_max_rcsa_range_values ('RSR'), rprowbproc.fn_max_rcsa_range_values ('RSR') - 1, pro_risk_score)
Can any one suggest a way to improve the performance of the query.
Thanks & Regards,

Hi,
Please find below table structure and insert scritps. Requesting for vluable help.
create table temp2 (col1 number,col2 varchar2(10),col3 number,col4 varchar2(20));
insert into temp2 values (1,'a',100,'vvv');
insert into temp2 values (2,'b',200,'www');
insert into temp2 values (3,'c',300,'xxx');
insert into temp2 values (4,'d',400,'yyy');
insert into temp2 values (5,'e',500,'zzz');
insert into temp2 values (6,'f',600,'aaa');
insert into temp2 values (7,'g',700,'bbb');
insert into temp2 values (8,'h',800,'ccc');
I am trying to get same output, what we get from below UNION query with ANALYTICAL Function.
select * from temp2 where col1 in (1,2,3,4,5)
union
select * from temp2 where col1 in (1,2,5,6)
union
select * from temp2 where col1 in (1,2,7,8);
I am seeking help by this dummy example to understand the concept, how can we use analytical functional over UNION or OUTER JOINS.
In my exact query, I am using same table three times adding UNION clause. here also we scan temp2 three times, so for bulky tables using 'union' would be hampering query's performance
It means i go with three time scans of same table that is not performance oriented. With the help of above required concept, i will try to remove UNIONs from my exact query.
Thanks!!Thanks for your time BluShadow and sorry as i think i couldn't make my query clear.
I try it again. Below there are three queries, you may see all three queries are using same tables. Difference in all three queries are just few conditions, which makes all three queries diff with each other.
I know, u cant run below query in your database, but i think it will convey my doubt to you. I have mentioned no. of rows with each clause and total i am getting 67 rows as my output. (Reason may be first n third query's result set are the subset of Second Query dataset)
So i want to take all common rows as well as additional rows, if present in any of the query. This is getting easliy done with UNION clause but want to have it in other way as here my same is getting scanned again n again.

My machine has gone dead slow. I have to wait for minutes to perform every single function. Like it stopped typing four times during this question.
If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the boot drive, or some other hardware component, is failing. Back up all data immediately, then run the Apple Hardware Test or Apple Diagnostics.
Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly. -
Query performance on RAC is a lot slower than single instance
I simply followed the steps provided by oracle to install a rac db of 2 nodes.
The performce on Insertion (java, thin ojdbc) is pretty much the same compared to a single instance on NFS
However the performance on the select query is very slow compared to single instance.
I have tried using different methods for the storage configuration (asm with raw, ocfs2) but the performance is still slow.
When I shut down one instance, leaving only one instance up, the query performance is very fast (as fast as one single instance)
I am using rhel5 64 bit (16G of physical memory) and oracle 11.1.0.6 with patchset 11.1.0.7
Could someone help me how to debug this problem?
Thanks,
Chau

http://blog.tanelpoder.com/2008/08/03/library-cache-latches-gone-in-oracle-11g/
check about memory MEMORY_TARGET initialization parameter.
By the way you have high "DB CPU"(47.5%), you should tune about your sql statement (check sql in report and tune)

Copy Function with Single selection of row
I want to copy necessary Planning items in my Input ready query from period 1 to remaining periods based on variable entries. To achieve this I have created a copy planning function to copy amount entered in period 1 (variable) to range of posting period variable entries (e.g. 2 -12 or 6-12).
I have created structure for GL accounts and I want to copy from period 1 to 2 - 12 for one row at a time.
I have created WAD template, I selected in behavior section of Analysis item, single with command option and assigned Planning sequence (consisting of copy function) as command.
On execution of WAD, I select single row in my input ready query and instead of one row getting copied over to the range of posting period, all rows consisting of Planning Items with amount are getting copied over, which I am not expecting with single selection option.
How can I have only one row getting copied over?
Am I am missing something?
Your suggestions are highly appreciated.
Regards,
SachinHello Gregor,
Thanks for your response. I tried what you have suggested and also followed the documentation, not sure why it is not working as expected
In my variable I have characterictis such as:
Version
Fiscal Year
Fiscal Year Variant
Profit Center
In my rows:
Planning Item
Columns:
Period
Amount
In behavior I have selected Row Selection Single. I am using Button group and assigned following:
Command: Execute a Planning Function -> In Data Binding -> Selection Binding -> Characteristic -> Planning Item -> Binding Type -> Item Characteristic -> Web Item Selection -> Item Binding -> Query (Analysis Item) -> Characteristic -> Planning item.
For Variable I have defined nothing.
Do you think my settings are correct?

Query performance - A single large document VS multiple small documents
Hi all,
What are the performance trade offs when using a single large document VS multiple small documents ?
I want to store xml snippets with similar structure in a container. Is there any benefit while querying, if I use a single large document to store all these snippets against adding each snippet as a different document. Would it degrade the performance when adding an xml snippet each time by modifying an existing document?
How could we decide whether to use a single large document VS multiple small documents?
Thanks,
AnoopHello Anoop,
In case you wanted to get a comparison between the storage types for containers, wholedoc and node, let us know.
What are the performance trade offs when using a
single large document VS multiple small documents ?Depends on what is more important to you, performance when creating the container, and inserting the document(s) or performance when retrieving data.
For querying the best option is to go with smaller documents, as node indexes would help in improving query performance.
For inserting initial data, you can construct your large document composed of smaller xml snippets and insert the document as a whole.
If you further want to modify this document changing its structure implies performance penalties; more indicated is to store the xml snippets as documents.
Overall, I see no point in using a large document that will hold all of your xml snippets, so I strongly recommend going with multiple smaller documents.

Error with single quotes in open document function
Hi all,
I have an issue with the special characters using the open document function. I'm passing a name, and I'm using the URLEncode function, but it doesn't work for single quotes, it shows a javascript error. I tried with HTMLEncode and it works for single quotes, but not for the other special characters like @,+. I tried with both functions at the same time but it doesn't work either.
Please let me know if you know how to solve it.
Thanks,
MarcelaHi Prashant,
I did not work it works for single quotes only, but not for other special characters.
This one doesn't work for single quotes
="<a href='../../scripts/openDocument.aspx?sType=wid&sDocName=Report_Name&sWindow=NEW&sReportName=Company Details&lsSPartner Id=" + [Partner Id] +"&lsSPartner Name=" + URLEncode([Partner Name]) +"'>View catalog</a>"

Problem with query performance
Hi All,
While loading data if we run the report, will it make any difference in the query performance? I have a cube with 230 million records I am running the delta which has got another 230 million records. Now I am trying to run the queries on the cube, all those timed out.
But I have a DSO with the 480 million the same queries are running good on the DSO. But I wanted to run the reports on the cube not on DSO what can I do? Is the data load giving any problem in the query runtime??
Pleas advise me what to do?
Regards
KiranHi,
My load got finished, Now i created indexes and tried to run the query, every query on this cube times out.. but on the top of DSO we have Same queries those queries are running.. what could be the reason how can i go ahead to improve the query performance plzzz advise me

Is there a way to combine their query results into a single function
say I have a bunch of functions that return a query:
<cffunction name="getDeals" access="remote"
returntype="query">
<cffunction name="getDeals2" access="remote"
returntype="query">
is there a way to combine their query results into a single
function that returns a struct of the various results?Umm, it's probably more suited to an array - effectively
making it into a list of queries. You'd then loop the array and
output each.
I use a similar approach when creating system messages to the
user. Most of my functions that are called do their bit, then at
the end call another function I call "messages". This function
grabs whatever my function sends and appends it to a messages
array.
This way enables me to output a long list of messages -
because I could be calling several functions at the same time. If I
just output a message from each function, each one would overwrite
the other. So I'd get one message at a time.
Immediately after it's output, I then destroy the message
array so that old messages aren't kept inside of it.

Single report with multiple queries OR multiple reports with single query
Hello Experts,
I have a confusion regarding Live Office connection for many days. I asked many people but did not get a concrete answer. I am re-posting this question here and expecting an answer this time.
The product versions that I am using are as follows:
FrontEnd:
BOE XI 3.1 SP4 FP 4.1
Xcelsius Enterprise 2008 SP4
Backend:
SAP BW 7.0 EHP1
I have created a dashboard which is getting data from a webi report using LO connections.
The webi report has five report parts which are populated by five different queries.
Now my question is, when the five LO connections are refreshed, is the webi report refreshed five times or just once?
If the report is refreshed five times, then I guess it is better to have five different webi reports containing single report part, because in that way we can prevent same query being executed multiple times.
SO what is the best practice- to have a single report having multiple queries - OR - to create multiple webi reports with single query?
Thanks and Regards,
PASGHI
I think Best Practice is Multiple reports with single query
Any way If LO connections refresh 5 time the query will refresh 5 timesRegards
