Which gives better performance in webi using display attr or nav attr -

Hello all,
We are using the Bex query as the datasource for our universes and the end user is using the Web Intelligence as the reporting tool (rich client and infoview) we have employee as one of the infoobject in the cube.
Now employee has a lot of attributes which the user wants to use for reporting (delivered employee infoobject has quite a few attr), we are making some of them as Nav attr like Org unit since they are time dependent and the end user will need to put in the key date to bring the employees from right org unit.
We have enhanced the employee attr to have the all address information of the employee (Z fileds) and we have made those nav attr in RSd1.
So my question is should we make the address Z fields as nav attr in cube as well and use those objects in webi or can we use the objects in webi which fall under employee like details (green icons) rather than separate object.
Please let me know what will keep better performance and what is the best practice.
Thanks you in advance and appreciate everyone's help

Hi,
BEx Query Design Recommendations:
"Reduce Usage of Navigational Attributes as much as possible Also, if simply displaying a Characteristicu2019s Attribute, DO NOT use the Navigational Attribute u2013 rather utilize the Characteristic Attribute for display in the report This avoids unneeded JOINS, and also reduces total number of rows transferred to WebI"

Hi All,
In the below two queries which gives better performance.
Requirement is I need to find if all the 3 score columns are null then I need to assign -ve value -9999 else some +ve value 2
1)
select case when count(CUST_score1)+count(CUST_score2)+count(CUST_score3)=0 then -111111'
else 11 end
from
customer
where subscriber_id=1050
and cust_system_code='1882484'
2)
select case whenCUST_score1 is null and CUST_score2 is null and CUST_score3 is null then '-9999'
else '11' end
from
customer
where subscriber_id=1050
and cust_system_code='1882484'
Please help, because we have more data in table customer so I need to confirm which is better.

Regards,
ChandaThe two statements aren't equivalent. If you know that your where condition is restricting to a single row then there is no point in doing a count as that will introduce an additional aggregate function that isn't required for a single row. If you are dealing with multiple rows from the where condition then the second query will return multiple rows whereas the first query returns 1 row, so they don't do the same thing anyway.

Which gives better performance

I have to two arraylists. I have to sort one based on the other. The way i did was to iterate one over the other. Or may be I have to load one arrylist into a hashmap and then do hashmap.get to get to the individual items?
MR

I find this an interesting problem so I had a go at it just to understand what one has to do -
import java.util.*;
public class Fred
    public static void main(String[] args)
        // Create the reference
        final ArrayList<Integer> reference = new ArrayList<Integer>();
        for (int index = 0; index < 100; index++)
            reference.add(index);
        Collections.shuffle(reference);
        // Now some data to work with
        final Random random = new Random();
        final ArrayList<Integer> data = new ArrayList<Integer>();
        for (int index = 0; index < 1000; index++)
            data.add(random.nextInt(100));
        // Build the map needed in the sort comparator
        final HashMap<Integer,Integer> sortHelper = new HashMap<Integer,Integer>();
        for (int index = 0; index < reference.size(); index++)
            sortHelper.put(reference.get(index), index);
        // The 'indirect' comparator
        final Comparator<Integer> comparator = new Comparator<Integer>()
            public int compare(Integer left, Integer right)
                Integer leftIndex = sortHelper.get(left);
                Integer rightIndex = sortHelper.get(right);
                if (leftIndex == null)
                    return 1;
                else
                    return leftIndex.compareTo(rightIndex);
        // Now sort
        Collections.sort(data, comparator);
        // Test the result - how?
}So how does one test the result?

For my game's better performance, should i use Starling?

I heard that using Starling gives better performance than just using Flash pro Native (GPU mode??) when playing flash games on smartphones.
However, according to this article, there is not much difference between GPU mode and Starling although its recorded in late 2012.
http://esdot.ca/site/2012/runnermark-scores-july-18-2012
My game is tile matching game that uses vectors and many different tile pictures. also upto 64 tiles can be present at the same time.
I don't know how much more performance Starling would provide, but if starling would give more performance, i don't know if its worth the time and effort to learn how to use Starling and change my current codes to use Starling?

This is a test between multiple frameworks that all use Stage3D, which is basically the means to get any hardware benefits from the GPU.
These frameworks do nothing else than helping to streamline your game development and doing some optimizing (object pooling etc.) under the hood.
The basic concept is to have spritessheets (for 2D) , that are also called "Textureatlas`" instead of the "old" method of having separated MovieClips/sprites.
If you dont use this method in your game, then you will have indeed no benefit from Starling or any other Stage3D framework.
So if you your game is coded "like in the old days" you would have to rewrite some parts of it and convert all MovieClips to Spritesheets to benefit from the GPU.
The real Performance-comparison reads like this:
CopyPixels (the PreStage 3D method) had a Perfomance gainof 500%/ SpriteSheet (Stage3D) 4000% compared to the "old way".
It all depends if you`re unhappy with your games curretn performance on current mobile devices or not.

In PI 7.1 better performance is reached using RFC or Proxy?

Hello Experts,
As with PI 7.1 which one would be better option to have better performance?
1)Proxy which goes through the Integration Engine by omiting Advance adaptor Engine
2)RFC which goes through the AAE by omiting Integration Engine
As we know there are alot of advantages of Proxies over RFC:
1. Proxy communication always by passes the Adapter Engine and will directly interact with the application system and Integration engine. So it will give us better performance.
2. Proxies communicate with the XI server by means of native SOAP calls over HTTP.
3. Easy to handle messages with ABAP programming if it is ABAP Proxy .
4. Proxy is good for large volumes of data. we can catch and persist the errors ( both system & application fault ) which was generated by Proxy setting.
Thanks in Advance
Rajeev

Hey
More than the performance,its a question of requirement.
There are several restrictions which you need to consider before using AAE.To name a few
IDOC,HHTP adapter wont be available
No support for ABAP mapping
No support for BPM
No support for proxy
No support for Multimapping,content based routing ( in first release)
So if you want to use any of the above you cant use AAE in first place.but performance is significantly improved,upto 4 times better that simple AE-IE
/people/william.li/blog/2008/01/10/advanced-adapter-engine-configuration-in-pi-71
check the above blog and the article mentioned in it.
Now coming to proxy,it supports all the above and performance is not that bad either.
so it all boils down to what your requirements are:)
Thanks
Aamir

Which is better with a NAS: using Sharing or Library location?

So I've got my brand new NAS up and running (Netgear ReadyNAS 104).
It has a Music folder with an iTunes server so I can use it as a Shared Library.
But I can also point my iTunes to the NAS and use the library directly from the NAS.
So which is better? Using the NAS as a Shared Library or use the NAS as the primary Library?
I want multiple devices (primarily Apple devices, but perhaps also a Windows laptop) to be able to use the media.
What about library management? Like when ripping an audio CD. When I use the NAS as a shared library, do I need to manually copy the CD to the NAS iTunes share and have iTunes re-scan?

Well... I downloaded LibreOffice and Writer2ePub and openned my Atlantis doc in it and converted to epub file. The good news is it didn't cost a dime.
The bad news is one image is now tiny which is odd because it was 600 dpi so I would think it could be displayed larger, not smaller but maybe the epub conversion downsizes a higher res image (some are 300dpi).
The cover image shows up in iBook as a wide and short image. The cover itself is tiny and then it just fills in black for the rest of the screen width. I used a large, high res image.
Then there was something with the TOC. It created a good TOC but then there's another page with a none hypertext version and a big rectangle error message and the TOC only shows about half of the chapters.
There was some advice on the internet about centering images in iBook. It seems that iBook doesn't recognize text justification coded in a document. So you have to embed another element on the same line as the image (html stuff) and give it a center alignment tag. I haven't done any html ebook stuff so I may not be explaining that the best way possible.
So, I'm going to take another look at my iBook Author version and see if I can live with that. If not I'll probably try Pages although I don't know what other problems I'll run into. Fun, fun, fun

Which provides better performance?

I have a ATI HD3200 video built-in to my motherboard. I also have an old Nvidia 6600 GT 128 MB videocard. Which will give me better performance?
I have the desktop effects enabled in KDE 4.2 and I also like to play the occasional 3D game.

For desktop use with compositing i'd agree with Draje. For games, you can easily enough benchmark each card and see which is best. If you go this route I strongly recommend using a lighter weight wm just when you play games. I know my own comp went up 40fps or so when playing nexuiz under fluxbox as opposed to KDE 3.5.x.

Which is better when temporarily not using Mac - 'screensaver' or 'sleep'?

I manually invoke a screensaver when I won't be using my MacBook for a while (up to an hour or two) -- instead of putting it to sleep.
When I come back to use the computer again, with rare exceptions the hard drive doesn't rev up as it does when I return to use the Mac after putting it to sleep (either manually or by closing the case).
Is one of these better, in terms of wear and tear on the hard drive?
Also, does the fact that the computer's hard drive apparently does not rev up when use of the computer is resumed from the screensaver (rather than from 'sleep') mean that the hard drive has been spinning (idling) the whole time?
If so, is putting the computer to sleep preferable, since it essentially turns the hard drive 'off' rather than allowing it to spin the entire time that the computer isn't being used?
Thanks.

When to choose sleep rather than screen saver.
When to choose sleep over shutdown.
I usually always let my display go to sleep and then my computer
go to sleep before my screen saver is set to start. I have it set this way for
both power adapter and battery. I have my screen saver setup with a
slideshow but seldom use it. I have it setup to require a passcode when
waking from sleep or screen saver. If I want to download a large update
that would take a couple of hours I choose never for computer sleep and
a couple of minutes for display sleep in both power adapter and battery.
I only shutdown my computer when I am done for the day. If I'm getting up
to make a fresh pot of coffee or something I close the lid eventhough I have
display sleep and computer sleep set.
These are my preferences and the way I like them. You should adjust these settings
on your MacBook so that it is comfortable for you to use.
I noticed that your MacBook is about 4 years old (early or late 2006 model). Are
you asking these "When To" questions to try to prolong the life of your computer's
hardware? If so, my best answer would be:
+Backup your important folders and media at least twice+. Hardware can fail at anytime.
I have read of 2 week old MacBook Pros being sent back to Apple for hardware
replacement. If you have Kernel Panics, questionmark, a blue or black screen; system
preferences set to what someone thinks will provide hardware longevity won't be as
useful as a good backup. I should have started this with an "in my humble opinion".
Limnos has already said that some will argue both ways on the wear and tear savings
in an earlier reply.
Set your preferences to where they are most comfortable for you and enjoy using your
computer.

Which is the BEST Java Web Service Framework to use?

Hi all,
I'm a beginner to Web Services.
I am planning to implement java web services to make the communication between java(Tomcat Server) and C# client.
I found list of web service frameworks like,
1. Apache Axis,(POJO,Axiom)
2. JSON-RPC,
3. Java Web Services Development Pack ,
4. Web Services Invocation Framework,
5. Xfire,
6. XML Interface for Network Services. ...
Please do reply me that which web service framework will be efficient to use.

But, I want to know which Framework will provide
better performance?
better than what?
Also I want to develope the web service as a standard
one andeach has it's own quircks and implementation details. Each should be able to generate and accept the same SOAP messages though if you implement them properly.
It should be able to provide bulk data exchange.
That will depend in large part on your hardware.
Please suggest a web service framework
(Java-based) which will give better performance.again, better than what?
Better than messenger pidgeons?
Better than swallows (European or African)?
And if so, how heavy would the message capsule be? 2 swallows may be able to carry a coconut together, holding it on a piece of string.

Which is better for performance Azure SQL Database or SQL Server in Azure VM?

Hi,
We are building an ASP.NET app that will be running on Microsoft Cloud which I think is the new name for Windows Azure. We're expecting this app to have many simultaneous users and want to make sure that we provide excellent performance to end users.
Here are our main concerns/desires:
Performance is paramount. Fast response times are very very important
We want to have as little to do with platform maintenance as possible e.g. managing OS or SQL Server updates, etc.
We are trying to use "out-of-the-box" standard features.
With that said, which option would give us the best possible database performance: a SQL Server instance running in a VM on Azure or SQL Server Database as a fully managed service?
Thanks, Sam

hello,
SQL Database using shared resources on the Microsft data centre. Microsoft balance the resource usage of SQL Database so that no one application continuously dominates any resource.You can try the
Premium Preview
for Windows Azure SQL Database which offers better performance by guaranteeing a fixed amount of dedicated resources for a database.
If you using SQL Server instance running in a VM, you control the operating system and database configuration. And the
performance of the database depends on many factors such as the size of a virtual machine, and the configuration of the data disks.

Choosing between SQL Server in Windows Azure VM & Windows Azure SQL Database

Guys, I am planning to change my phone soon. i am using Nokia E6 for last two years and confotable with its performance. Though I had a bitter experience (you can read my experience HERE) at the begginning, it never came back after rectification done at nokia care. I am happy with its performance now. However, since it has a small screen, sometimes i feel difficult to select a link with finger while surfing through internet. That is the reason i am looking for a new one with bigger screen size. I was actually looking for Lumia 820 or 720 for which I am still confused to decide one. Request the experts to help me to select one. Which is better for my moderate use? i am using my phone mainly for calls, emails, photos and web browsing. I am not curious about games, music etc... Please help me to chose one.

Which is better poower supply or recharge??

which is better while i'm using my Mac : to put the power supply even if the battery is full or recharge every time the battery dies and remove the power supply??

There's nothing wrong with running from the AC adaptor. You cannot overcharge the battery nor will it cause any battery memory effects.

Which is better to use: BEx query or Web Application as an iView in portal?

Hi gurus!
Are there any experienced opinions, which is better - publish a BEx query in portal or publish a BEx Web Application in portal? Is it easier to alter the layout attributes etc. if I create a BEx Web Application first before publishing?
What is the way of fixing for example filter item height if I publish BEx query in portal - is there a Web Application that it uses anyhow which I can fix? Or can I use in that case iView -properties in portal?
Thankful for advice
Sari

ok, means i can use jsp:useBean tag for all my
classes that are not actually bean. so it will be
instantiated at run time and provide efficiency .No. Jsp:useBean is used for java bean components.
>
but when should i use import statement in my jsp and
it happen at translation time so will it create any
type of burden for my code if i import multiple
classes.For non-java beans, you need to import the classes, period.
It's not a burden, it's a necessity.
