Strange load performance...

Hi, folks!
My SWF-files don´t seem to load the way i want after publication. I usually build in a kind of loading bar to show loading process while loading, it should be visible right away, till the main movie starts playing. But the browser seems to wait, it doesn´t show anything, behaves like if it were waiting for the whole lot to be downloaded before it can show the very first frames, which lets my loading-bar look pretty senseless. Why the hell does it do that? Is there anything in the settings i don´t know about? Could be the problem somewhere else, and not within the Flash-environment?
Thanks a lot for any help!

I´m dead sure nothing is being exported in the first frame, I´ve checked it carefully about fifty odd times, specially after you and ross called my attention upon it. If there were anything big there, it would show up on the bandwith profiler while checking download performance -it does if I deliberately check the "export in first frame" box as a try, the simulated download behaviour looks then very much like the one I´m experiencing "under real fire" though having taken entirely different settings...!! I´m going mad about this, guys...
What about the entries in the HTML-file:
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="1000" height="590" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="pict/salvadore_images.swf" /><param name="quality" value="high" /><param name="bgcolor" value="#323642" /><param name="SCALE" value="exactfit" /><embed src="pict/salvadore_images.swf" width="1000" height="590" align="middle" quality="high" bgcolor="#323642" scale="exactfit" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>
Anything wrong, anything missing?
Thanks again for any help!

I was wondering what causes this exception. Some user accounts in the same machine
don't have this problem.
I also wondering if it will cause performance problem when the traffic is high.
We already applied the patches.
Any hits and suggestions are welcome.

Dear Deyan,
Thanks for your help. We do have $WEBLOGIC_HOME/lib/solaris in LD_LIBRARY_PATH,
which is set when running ". setEnv.sh" before startWebLogic.sh.
We failed on one patch: 105210-27, for some reason.
The strange thing is: in the same machine, all WL60 instances running under user
accounts (under /users/developers/) have no such error. But it happens under some
account, like accounts under /export/home/, etc. /user/developers is mounted on
another physical machine.

You should have the $WEBLOGIC_HOME/lib/solaris directory in your LD_LIBRARY_PATH
so that
the server can load the performance pack (which is a shared library called
libmuxer.so).
If it is present then do a ldd libmuzer.so and you will see if any libraries
that it
depends on are missing.
Also make sure you have all of the requered patches for 2.6 installed.

BW Back end
Some Tips -
1)Identify long-running extraction processes on the source system. Extraction processes are performed by several extraction jobs running on the source system. The run-time of these jobs affects the performance. Use transaction code SM37 Background Processing Job Management to analyze the run-times of these jobs. If the run-time of data collection jobs lasts for several hours, schedule these jobs to run more frequently. This way, less data is written into update tables for each run and extraction performance increases.
2)Identify high run-times for ABAP code, especially for user exits. The quality of any custom ABAP programs used in data extraction affects the extraction performance. Use transaction code SE30 ABAP/4 Run-time Analysis and then run the analysis for the transaction code RSA3 Extractor Checker. The system then records the activities of the extraction program so you can review them to identify time-consuming activities. Eliminate those long-running activities or substitute them with alternative program logic.
3)Identify expensive SQL statements. If database run-time is high for extraction jobs, use transaction code ST05 Performance Trace. On this screen, select ALEREMOTE user and then select SQL trace to record the SQL statements. Identify the time-consuming sections from the results. If the data-selection times are high on a particular SQL statement, index the DataSource tables to increase the performance of selection (see no. 6 below). While using ST05, make sure that no other extraction job is running with ALEREMOTE user.
4)Balance loads by distributing processes onto different servers if possible. If your site uses more than one BW application server, distribute the extraction processes to different servers using transaction code SM59 Maintain RFC Destination. Load balancing is possible only if the extraction program allows the option
5)Set optimum parameters for data-packet size. Packet size affects the number of data requests to the database. Set the data-packet size to optimum values for an efficient data-extraction mechanism. To find the optimum value, start with a packet size in the range of 50,000 to 100,000 and gradually increase it. At some point, you will reach the threshold at which increasing packet size further does not provide any performance increase. To set the packet size, use transaction code SBIW BW IMG Menu on the source system. To set the data load parameters for flat-file uploads, use transaction code RSCUSTV6 in BW.
6)Build indexes on DataSource tables based on selection criteria. Indexing DataSource tables improves the extraction performance, because it reduces the read times of those tables.
7)Execute collection jobs in parallel. Like the Business Content extractors, generic extractors have a number of collection jobs to retrieve relevant data from DataSource tables. Scheduling these collection jobs to run in parallel reduces the total extraction time, and they can be scheduled via transaction code SM37 in the source system.
8). Break up your data selections for InfoPackages and schedule the portions to run in parallel. This parallel upload mechanism sends different portions of the data to BW at the same time, and as a result the total upload time is reduced. You can schedule InfoPackages in the Administrator Workbench.
You can upload data from a data target (InfoCube and ODS) to another data target within the BW system. While uploading, you can schedule more than one InfoPackage with different selection options in each one. For example, fiscal year or fiscal year period can be used as selection options. Avoid using parallel uploads for high volumes of data if hardware resources are constrained. Each InfoPacket uses one background process (if scheduled to run in the background) or dialog process (if scheduled to run online) of the application server, and too many processes could overwhelm a slow server.
9). Building secondary indexes on the tables for the selection fields optimizes these tables for reading, reducing extraction time. If your selection fields are not key fields on the table, primary indexes are not much of a help when accessing data. In this case it is better to create secondary indexes with selection fields on the associated table using ABAP Dictionary to improve better selection performance.
10)Analyze upload times to the PSA and identify long-running uploads. When you extract the data using PSA method, data is written into PSA tables in the BW system. If your data is on the order of tens of millions, consider partitioning these PSA tables for better performance, but pay attention to the partition sizes. Partitioning PSA tables improves data-load performance because it's faster to insert data into smaller database tables. Partitioning also provides increased performance for maintenance of PSA tables for example, you can delete a portion of data faster. You can set the size of each partition in the PSA parameters screen, in transaction code SPRO or RSCUSTV6, so that BW creates a new partition automatically when a threshold value is reached.
11)Debug any routines in the transfer and update rules and eliminate single selects from the routines. Using single selects in custom ABAP routines for selecting data from database tables reduces performance considerably. It is better to use buffers and array operations. When you use buffers or array operations, the system reads data from the database tables and stores it in the memory for manipulation, improving performance. If you do not use buffers or array operations, the whole reading process is performed on the database with many table accesses, and performance deteriorates. Also, extensive use of library transformations in the ABAP code reduces performance; since these transformations are not compiled in advance, they are carried out during run-time.
12)Before uploading a high volume of transaction data into InfoCubes, activate the number-range buffer for dimension IDs. The number-range buffer is a parameter that identifies the number of sequential dimension IDs stored in the memory. If you increase the number range before high-volume data upload, you reduce the number of reads from the dimension tables and hence increase the upload performance. Do not forget to set the number-range values back to their original values after the upload. Use transaction code SNRO to maintain the number range buffer values for InfoCubes.
13)Drop the indexes before uploading high-volume data into InfoCubes. Regenerate them after the upload. Indexes on InfoCubes are optimized for reading data from the InfoCubes. If the indexes exist during the upload, BW reads the indexes and tries to insert the records according to the indexes, resulting in poor upload performance. You can automate the dropping and regeneration of the indexes through InfoPackage scheduling. You can drop indexes in the Manage InfoCube screen in the Administrator Workbench.
14)IDoc (intermediate document) archiving improves the extraction and loading performance and can be applied on both BW and R/3 systems. In addition to IDoc archiving, data archiving is available for InfoCubes and ODS objects.
Hope it Helps

Unable to load performance pack using JRockit 26.3 on Solaris 10

Hi all,
I'm getting the following error when starting up my WebLogic 9.1 server instance on Solaris 10. I've recently upgraded from Sun's JVM to JRockit 26.3. I do not get this error when using Sun's JVM.

JRockit on Solaris is 64-bit so it needs the 64-bit performance pack files, so you need to have $WL_HOME/server/native/solaris/sparc64 in the LD_LIBRARY_PATH instead of $WL_HOME/server/native/solaris/sparc

What are the better load/performance testing tools available for Flex Application with BlazeDS RO?

In my application is designed with Flex3, ActionScript3, BlazeDS Remote Objects.
Just i tried with OPENSTA but i cant do the dynamic parameterization in their generated scripts because the response of the calls is binary values and also we cant get the response using with SCL language.
While testing with OPENSTA with HttpService, i can do the dynamic parameterization and got the response.
can give the information about the below questions
whether we can do dynamic parameterization with OPENSTA for Flex Remote objects?
and what are the better load/performance tools available for Flex Remote Objects?

Your approach is fine, depending on how many and what type of CFCs you are talking about. If they are "singletons" - that is, only one instance of each CFC is needed to be in memory and can be reused/shared from multiple parts of your application - caching them in the application scope is common. Just make sure they are thread safe ("var" or local.* all your method variables).
You might consider taking advantage of a dependency injection framework, such as DI/1 (part of the FW/1 MVC framework), ColdSpring, or WireBox (a module of the ColdBox platform that can be used independently). They have mechanisms for handling and caching singletons. Then you wouldn't have to go to the application scope to get your CFC instances.

FORMS CRASHES (FRM-92101) ON AS 10.1.2.0.2 DURING LOAD PERFORMANCE TESTING

Hiya
We have been doing Load Performance Testing using testing tool QALoad on our Forms 10g application. After about 56 virtual users(sessions) have logged-in into our application, if a new user tries to log-in into our application, the Forms crashes. As soon as we encounter the FRM-92101 error, no more new forms session are able to start.
The Load Testing software start up each process very quickly, about every 10 seconds.
The very first form that appears is the login form of our application. So before the login screen appears, we get FRM-92101 error message.
However, those users who have already logged-in into our application, they are able to carry on their tasks.
We are using Application Server 10g 10.1.2.0.2. I have checked the status on Application Server through Oracle Enterprise Manager Console. The OC4J Instance is up and running. Also, server's configuration is pretty good. It is running on 2 CPUs (AMD Opteron 3GHz) and has 32GB of memory. The memory used by those 56 sessions is less than 3GB.
The Applicatin Server is running on a Microsoft Windows Server 2003 64bit Enterprise Edition.
Any help will be much appreciated.
Cheers

Hi Shekhawat
In Windows Registry go to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems
In the right hand side panel, you will find String Value as Windows. Now double click on it (Windows). In the pop up window you will see a string similar to the following one:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16
Now if you read it carefully in the above string, you will find this parameter
SharedSection=1024,20480,768
Here SharedSection specifies the system and desktop heaps using the following format:
SharedSection=xxxx,yyyy,zzzz
The default values are 1024,3072,512
All the values are in Kilobytes (KB)
xxxx = System-wide Heapsize. There is no need to modify this value.
yyyy = IO Desktop Heapsize. This is the heap for memory objects in the IO Desktop.
zzzz = Non-IO Desktop Heapsize. This is the heap for memory objects in the Non-IO Desktop.
On our server the values were as follows :
1024,20480,768
We changed the size of Non-IO desktop heapsize from 768 to 5112. With 5112 KB we managed to test our application for upto 495 virtual users.
Cheers

Initial Load Performance Decrease

Hi colleagues,
We noticed a huge decrease initial load performance after installing an
application in the PDA.
Our first test we downloaded one data object with nearly 6.6Mb that
corresponds to 30.000 registries with eight fields each. Initial Load
to PDA took only 2 minutes.
We performed a second test with same PDA after a reinstallation and
new device ID. The difference here is that we installed an MI
application related to same data object. Same amount of data was sent
to the PDA. It took 3 hours to download it.
In third test we change the application in order not to have the
related data object assigned to it. In this case, download took 2
minutes again.
In other words, if we have an application with the data object
assigned, it results in a huge decrease in initial load.
In both cases we use direct connection to our LAN.
Here goes our PDA specs:
- Windows Mobile 6 Classic
- Processor: Marvell PXA310 de 624MHz
- 64MB RAM, 256MB flash ROM (190MB available to user)
Any similar experiences?
Thanks.
Edited by: Renato Petrulis on Jun 1, 2010 4:15 PM

I am confused on downloading a data object with no application.
I thought you can only download data if it is associated to a Mobile Component, I guess you just assign the DMSCV manually?
In any case, I have only experienced scenario two when we were downloading application with mobile component with no packaging of messages. we had maybe a few thousand records to download and process and it would take an hour or more.
When we enabled packaging, it would take 15-30 minutes.
Then I went to Create Setup Package because it was just simpler to install the application and data together with no corruption or failure of DMSCV not going operational and not sending data etc... plus it was a faster download using either FTP or ActiveSync to transfer the install files.

Sql Loader Performance

Hi
i have some question about SQL Loader. i have to find answers but did not get from Google or Documentation. i want to know that is there any way to check whether Sql loader inserting records with Direct path or Conventional path. As we know there are restriction in Direct load. Direct-path inserts do not support all objects that conventional inserts do. Their functionality
is restricted. If the database engine is not able to execute a direct-path insert, the operation is silently converted into a conventional insert. i have instruct Sql loader to insert using Direct=true and parallel as well. but it take 15 mint to loader 4 million record in table. i have observed its transfer rate is bit slow. i have oracle 11R2 on windows 2008 with 40GB RAM and SAN. how can i verify during execution either Sql loader load user Direct path or silently converted it conventional path. here is my sample control file. function used in control file will convert direct path to conventional?

Data Load performance in BI7.0

Hi,
I have a generic question regarding BI7.0.
From the perspective of data load performance what are the features that BI7.0 has compared to earlier versions.
Thanks in advance,,
Rama Murthy

Hi,
In BI, the entry layer is PSA, and it is mandatory to maintain the PSA to maintain the data in BI from any source. Here(in BI) it is possible to make the PSA as typed and untyped.
The Infopackage functionality is reduced, it will loads data up to PSA only.
The DTP upload the data between BI object in BI. Transformations replaces the updates rules and transfer rules.
DTP and Transformations removes the Data mart interface between the BI objects.
It is possible that, if no transformation of data is required, we can load data directly to target without maintaining the InfoSource.
All these properties are available bcoz of the new concept and new object type DataSource ie., BI DataSource (object type RSDS).
Depending on the situation, the InfoSource is not mandatory and at some times it is mandatory but PSA is mandatory in BI and rest of all are same as in 3.x.
Hope this helps in solving u r problem

SCD 2 load performance with 60 millions records

Hey guys!
I'm wondering what would be the load performance for a type 2 SCD mapping based on the framework presented in the transformation guide (page A1-A20). The dimension has the following characteristics:
60 millions records
50 columns (including 17 to be tracked for changes)
Has anyone come across a similar case?
Mark or Igor- Is there any benchmark available on SCD 2 for large dimensions?
Any help would be greatly appreciated.
Thanks,
Rene

Rene,
It's really very difficult to guesstimate the loading time for a similar configuration. Too many parameters are missing, especially hardware. We are in the process of setting up some real benchmarks later this year - maybe you can give us some interesting scenarios.
On the other side, 50-60 million records is not that many these days... so I personally would consider anything more than several hours (on a half decent hardware) as too long.

Extractor Designing to improve the Load performance.

Hi all,
I am extracting the data from MM application for this i am using the LO 2lis_02_itm extractor and i had enhanced it with 32 field and its happering my data load performance.
Could u pls let me know, how can i improve the data load performance.
Do i need to create the different Generic Extractors instead of enhancing the LO.
The DSO is also having many fields in it. Should i split it into 2 and create the Multiprovider for reporting.
Regards
KK

Hello,
my suggestion would be to create another generic DS for the logcal set of fields to be required in BI.
then you can load then seperately to different DSOs and then to single IC or to two IC and use MP to report on them.
Further you can check the below links:

Unable to load performance pack

Hi all,
Can anyone solve this problem.
I am starting weblogic server and it gives me message
"Unable to load performance pack, using java i/o.
It starts the server but it gives me above exception also.
Thanks.
Zahid.

Zahid,
Can you please provide the server version , service pack level and the
OS information.
Thanks
