Testing webdynpro browser performance

I am trying to add the tag: &sap.session.ssr.showInfo=true to the end of my webdynpro test app URL to see browser performance info in the status bar. But this is not working for me. I see nothing. I have tested with IE 6 and Firefox. The app works fine, but no perf. data is there.
Reference:
http://help.sap.com/saphelp_nw2004s/helpdata/en/05/fac4402418742ae10000000a155106/frameset.htm
http://help.sap.com/saphelp_nw2004s/helpdata/en/b5/7e1141e109ef6fe10000000a1550b0/frameset.htm
Note how in teh first above refernced doc, it says to use &sap.session.ssr.showInfo=true, while the next one says to use ?sap.session.ssr.showInfo=true. I have tried both, although I suspect the second doc is wrong.
Am I missing another setting to enable this?

Try "sap-wd-showInfo=true" or "sap-wd-ssr-showInfo=true" (I don't remember exactly).

Advice on constructing a test engine and formatting a spreadsheet test file to perform command line interface testing on a product through telnet or serial interface

Advice on constructing a test engine and formatting a spreadsheet test file to perform command line interface testing on a range of products through telnet or serial interface and output pass/fail results.

If I understand correctly, you want to do the following:
1. Create one or more tab-delimited files that specify a series of query strings (that LabVIEW will send to your products) and expected reply strings (that LabVIEW will look for in response to each query)
2. Run your LabVIEW program (the test engine) and have it execute one or more test scripts from file using either TCP/IP or serial communication to your units under test
3. Track how many of the queries are met with the expected response, and output an indication of whether each step passed or failed
If this is close to correct, then I've attached a sample test file and LabVIEW VI as an example; I chose the TCP/telnet method because it allowed me to use the ni.com Web site to simulate my tes
t hardware. If you happen to own the LabVIEW Internet Toolkit, there's a VI called "Telnet Play Script" in the Telnet palette that does something fairly similar using TCP. The same general model would also work for Serial communications.
Hope it helps,

Advice on constructing a test engine and formatting a spreadsheet test file to perform command line interface testing on a range of products through telnet or serial interface and output pass/fail results.

Hello j. smith,
TestStand gives you the ability to create "sequence files" which are lists of tests to be run sequentially or in parallel. These tests can be written in any language: LabVIEW VIs, C/C++ DLLs, EXEs, ActiveX objects, .NET Assemblies, etc.
You can run your TestStand sequence files from a command-line prompt using the following syntax:
\bin\SeqEdit.exe" /quit -run
This will launch the TestStand Sequence Editor (and optionally prompt you for TestStand login information if you have this configured), run your sequence file, then exit.
If you're using the TestStand process model, it can output your results to a report file or database if you configure this. To use a TestStand process mo
del to execute your sequence file, use the following syntax:
\bin\SeqEdit.exe" /quit -runEntryPoint
Here's an example:
C:\>"C:\Program Files\National Instruments\TestStand 3.0\bin\SeqEdit.exe" /quit -runEntryPoint "Single Pass" "C:\Program Files\National Instruments\TestStand 3.0\Examples\Demo\C\computer.seq"
Note that multiple sequences and sequence files can be specified on the command line.
TestStand supports remote sequence execution using DCOM (Distributed COM), which is an east way to remotely execute tests. But as for running tests or commands through a telnet or serial interface, you would have need to check Windows documentation on how to execute command-line remotely like this.

Testing Webdynpro Application using ECATT

Hi
all
I am going to test webdynpro Application using ecatt.For this in se80 I selected the
existing component(z component which was created by me) and i selected the application of that component and right clicked and selected START ECATT RECORDING and i have given the test cript name at that i have got one error USER ECATT_HTTPDoesnot exist. How to resolve this problem.
Please give me the soulution regarding this.

venkat

Hi Venkatesh,
Before you can start recording any webdynpro application make sure that the below settings are done in the ecatt system and the target system , for further information refer ecatt documentation.
Create User ECATT_HTTP in the eCATT System
The administrator in the eCATT system must create a user called ECATT_HTTP(with a password). The user requires no special authorization but must be a system user (in transaction SU01, display the user and choose the Logon data tab. Under User Type, select System).
Activate the Service ecatt_recorder in the eCATT System
       1.      In the eCATT System, start transaction SICF and navigate to the service ecatt_recorder.
       2.      Double-click on ecatt_recorder.
       3.      On the Logon Data tab, enter the user ECATT_HTTPand the password.
       4.      Choose Save.

How to test SQL query performance - realiably?

I have certain queries and I want to test which one is faster, and how big is the difference.
How can I do this reliably?
The problem is, when I execute the queries, Oracle does it's caching and execution planning and whatnot, and results of the queries are dependent on the order I execute them.
Example: query A and query B, supposed to return same data.
query A, run 1: 587 seconds
query A, run 2: 509 seconds
query B, run 1: 474 seconds
query B, run 2: 451 seconds
It would seem that A is somewhat faster than B, but if I change the order and execute B before A, results are different.
Also I'm running the queries in SQL Developer, and it only returns 100 first lines, how can I remove this effect and simulate real scenario where all lines are fetched?
I can also use EXPLAIN PLANs and look at the costs but I'm not sure how much I can trust those either. I understand they are only estimations and even if cost(a) = 1.5 * cost (b), b could still end up executing faster in practise due to inaccuracies in the cost calculation....right? EDIT: actually event if cost(a) = 5000 * cost(b), b can still execute faster.....seems like query A's cost is 15836 and B's cost is 3 while A seems to be faster in practise.

I have to say I don't understand your point either :)
What are you saying, that people should not test their SQL performance? That tools such as autotrace are useless?No.. what I'm saying is that you need a baseline to make an informed decision about SQL performance.
What does a 4 second SQL performance mean for query foo ? Nothing really.. wearing my dba cap I would point at that this is actually utterly useless for me to determine the impact of your query on production, or use it to determine how to scale it.
If instead you tell me that is hits that table using an index range scan.. I know what it is doing and have a far better idea what it will do to the production instance.
Thus my questioning this "+elapsed time+" measurement approach. I as a dba cannot use it... and I'm not sure what benefit (wearing my developer hat) you will find from it either.
You can form your SQL queries better or worse, or select your table structure / indexes better or worse. Some choices may end up executing orders of magnitude slower than others. Obviously you can't get exact measurements "this query executes in 43123 ns" and there are a lot of unpredictable variables that affect the end performance. Still, it's often better to test your querie's / table's performance before implementing them in the application than not.Exactly. I'm not questioning the fact that optimising your code (and ALL your code, not just SQL) is a Good Thing (tm) - but how you go about that optimisation process.
For example, your PL/SQL code fires off a query. It returns on average 10,000 rows, hits a single partition (SQL enables partitioning pruning) and then uses a local bitmap index to identify the rows.
An optimal query by the sounds of it, and one that will perform and scale well.. even when the database instance needs to service a 100 clients using your code and running this query.
Only, the code does a single bulk collect of all the rows and stuff it into dedicated process memory (PGA). Servicing a 100 clients means that dedicated server memory is now needed for 100x10000 rows - there's insufficient free memory, causing the kernel to start swapping pages in and out of memory heavily as all 100 client sessions are active and wanting to process the rows returned by the optimal query.
What happens to scalability and performance now?
Testing for performance is not simply measuring a query and then trying to use that or extrapolate that to determine application performance and the impact on production.
It starts with the design of the tables, the design of the application, the writing of the code (application and SQL). It is not something that should be done after the fact as in "+okay, application all done, let's see how she performs!+".. and especially not using time as the baseline for performance measurement.

Testing WebDynpro Adobe Interactive forms Using eCATT or any other testing

Hi All,
We are testing WebDynpro Adobe forms (Java). is there any methodology to test Interactive forms not normal webdynpro applications. Especially Interactive form with UI fields like dropdwons, datepickers dropdown values are from BAPI/RFC's in these forms we will perfom actions like send data to backend and display PO created in onther view.
once we repaly the test script all the drop down values are not updated this test scenario we tested with LR.
Is there any procedure to test this scenario using eCATT or any other testing Tool.
Rehards,
Murali

Hi Vara,
You can develop Interactive forms using WD ABAP also.
[E Learning- Interactive Forms using WD ABAP|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/media/uuid/c766e918-0b01-0010-99b1-c2b78cd059b3]
WD Java is useful in case, when your ABAP system is less than ECC 6.0. Otherwise you can achieve same functionalities in WD ABAP also.
Hope this will help you.

SQLDeveloper 1.5.4 Table browsing performance issue

Hi all,
I had read of previous posts regarding SQLDeveloper 1.5.3 table browsing performance issues. I downloaded and installed version 1.5.4 and it appears the problem has gotten worse!
It takes ages to display rows of this particular table (the structure is shown below). It takes much longer to view it in Single Record format. Then attempting to Export the data is another frustrating exercise. By the way, TOAD does not seem to have this problem so I guess it is a SQLDeveloper bug.
Can someone help with any workarounds?
Thanks

Hi Pawan
Is your engine functioning properly.I mean go to http://localhost:port/index.html then chech out the webdynpro links and other links available on this page .I am suggesting this so that we can check if sap.com/tcwddispwda
is working fine.Then we can look into the speacific application you are working on

WebDynpro Application Performance

Can any one guide me how to check WebDynpro Application Performance. I have application which refreshes every 1 hour. There are 1500-2000 users for this. Can any one guide me how to monitor and do changes for streamlining performance?
Also my application is using both VC and webDynpro in one page.
Thanks in advance

To can check the performance of the webdynpro application follow the procedure mentioned in the link below.

Improve browsing performance of a SSAS Dimension

Hi,
I have a huge dimension with almost 20 million rows. Browsing the Dimension takes a lot of time. Please help me on improving the dimension browse performance. I tried searching in the internet nut I am able nto find only the articles related
to improving the Measure performance but nothing about Dimension.
Regards,
Venkata
Venkata Koppula

Hi Venkata,
According to your description, you want to improve the performance of browsing a huge dimension. Right?
As yger mentioned, we could create a default measure in your cube. Otherwise it will query all measure groups when you pulling out your huge dimension. We can change the default measure to empty hidden field, which will speed up this
kind of queries. For more information about optimizing performance on dimension design, please refer to the link below:

Very slow browser performance

Hi and thanks in advance for your time.
My internet browsing is painfully slow. I tested the speed on speedtest.net and on speakeasy.net, the result were:
MP3 file download (5MB): 2 sec
Video clip (35MB): 14 sec
Movie (800MB): 5min
Download: 20 MB/s - 26053kbps
Upload: 6.52MB/s - 6594kbps
Ping: 71Ms
Another useful info is that since the last update, Safari has crashed few times, particularly with s website for music that has lots of QT videos. However, the speed was very slow even before the last update
I use Comcast with a DSL modem that was reset by comcast prior to performing the test (did not see improvement after that). Supposly, I got more speed that what I am paying for, but again, it is QUITE slow.
My computer is a 2Ghz PowerPC G5 running 2Gb RAM, bus speed: 667Mhz, 128MB video RAM, HD is 232GB (123 are used mainly on music, video, photos and keynote docs)
What can I do?
Thanks!

Let's try and deal with the slowness first:
Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /
Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )
Wikipedia also has an interesting article about Open DNS:
http://en.wikipedia.org/wiki/OpenDNS
Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:
This is Apple's guidance on iPv6:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html
Click on Apply Now and close the window.
Restart Safari, and repair permissions.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
If your Safari crashes, please copy and paste the crash report here.

Safari vs in-app-browser performance

I have heard that performance using in app browsing vs using safari on an ios device is much slower. Are there any signifant tests that can proove this?
In cases where a webpage is using gzip to compress webcontent, are there any known performance issues for in-app-browsing?

It happens but to a much lesser - almost unnoticeable - extent.

Wireless Speed Test Great - Browsing Not So Great

I have a wireless setup and my MacBook Pro web browsing seems to be a bit slow. I ran a speed test (FTP) and it was blazing for my connection (over 1MBPS on Hughes.netb Satellite). The web browsing doesn't equate to this speed. Are there any Safari settings I should check?

Some satellite systems have fairly high latencies. The "standard" tcp/ip configuration is not optimized for such connections. You might try installing Apple's Broadband Optimizer and see if it improves performance.
Note, however, that speedtests only benchmark your broadband connection's best throughput. Browsing on the other hand has more to do with individual site conditions. Some sites are slow, some are fast. It depends upon server capacity, bandwidth limits imposed, server load, and many other factors. Except for fast download servers you may rarely see surfing speeds as fast as the benchmark speed test.
