Multithread applications in SAP environment

Hello folks ,
I just got a huge task which require a lot of processing power.
i wonder if there's any way to build ABAP applications in way that multithreading or somthing similar could implemented
even with some patterns or any other technology .
Thanks for any ideas .

Hello Jerry
thank for your information but it's not was very clear from my side .
there's an difference between process and Thread .
A single process can have multiple threads that share global data and address space with other threads running in the same process, and therefore can operate on the same data set easily. Processes do not share address space and a different mechanism must be used if they are to share data.
If we consider running a word processing program to be a process, then the auto-save and spell check features that occur in the background are different threads of that process which are all operating on the same data set (your document in this case ).
process
In SAP computing env. , a process is an instance of a program that is being sequentially executed by a computer system that has the ability to run several computer programs concurrently.
for a Thread
A single process may contain several executable programs (threads) that work together as a coherent whole. One thread might, for example, handle error signals, another might send a message about the error to the user, while a third thread is executing the actual task of the...
i wonder if there's a way to implement the multitherading like in c++ for instance .

SSO to non SAP Application using SAP Logon Ticket

Hi Experts,
I Have EP 7 SP 15 using SPNego Wizard to SSO with Active Directory and SSO between EP and ECC using SAP Certificates.
Now I have a demand to SSO some JAVA based applications (non SAP) to my portal using the SAP Logon Ticket.
I Have followed some blogs that directed me to use SAPSSOEXT (some libs) to read the MYSAPSSO2 cookie. The problem is that I didn't found this cookie, I even executed the command javascript:document to look for this cookie but the browser just show me the JSESSIONID info.
Does anybody knows where I can find this cookie or if there's a better way to set up this SSO? It´s necessary to say that I cannot SSO these application to the kerberos protocol because some security reasons on my company.
Thanks
Armando

Hi,
I dont have much info related but i can giv u hint
refer OSS Notes 442401 and 723896.
When using SAP logon tickets for non-SAP applications, two different implementation options are available. The difference lies in where the ticket verification takes place.
In the first case, the SAP logon ticket is submitted to the web server filter located on the web server. The web server filter verifies the portal serveru2019s public key
certificate using its local Personal Security Environment (PSE) and then populates the HTTP header field with the user ID for SSO to the non-sap web application.
In the second case, the SAP logon ticket is sent to the non-SAP application, which then verifies it using the ticket verification DLL and submits the user ID to the application for SSO.

How to configure ENV and DB for multithreaded application?

Hi,
From document, I know DB_THREAD must be checked for both ENV and DB, but , I don't know which one is best choice for multithreaded application while facing DB_INIT_LOCK and DB_INIT_CDB. In my application, there maybe multi readers and writers at the same time, should I use DB_INIT_LOCK instead of DB_INIT_CDB? what other flags should I use?
DB_INIT_CDB provides multiple reader/single writer access while DB_INIT_LOCK should be used when multiple processes or threads are going to be reading and writing a Berkeley DB database.
Thanks for your seggestions and answers.

Thanks for the explanation,
The Berkeley DB Concurrent Data Store product
allows for multiple reader/single writer access
to a database. This means that at any point in time,
there may be either multiple readers accessing a
database or a single writer updating the database.
Berkeley DB Concurrent Data Store is intended for
applications that need support for concurrent updates
to a database that is largely used for reading.
If you are looking to support multiple readers and
multiple writers then take a look at the Transactional
Data Store product
(http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp.html)
In this case the Environment is typically opened with:
DB_INIT_MPOOL, DB_INIT_LOCK, DB_INIT_LOG, and DB_INIT_TXN.
Let me know if I missed any of your question.
Thanks,
Sandra

Error while running SDK application in XIR3 environment

Hi all,
Thanks for your support provided so far.
I have developed a SDK application using BOE SDK in BO XI-R2 environment. This application queries the CMC and provides the list of objects, users etc.,
While running the application in BO XI-R3 environment, when I invoke the Login button in my application, I'm getting the following Unhandled Exception as
"Could not load File or Assembly: "CrystalDecisions.Enterprise.Framework.Infostore version=11.5.3300.0, culture =neutral......."
Am I missing any Dll file to be included along with the EXE?
Can anyone help me in this regard?
Thanks.

Hello Bhuvan,
Do you have BusinessObjects Enterprise (BOE) 3.0 or 3.1? The .NET implementation was not released until BOE 3.1, so .NET applications wouldn't be expected to work against BOE 3.0.
Assuming that you have BOE 3.1, then you also have to upgrade your application. An Enterprise .NET application that references the XI R2 (v11.5) assemblies would not be supported for communicating with a BOE 3.1 system.
On it's face, the error is saying that Enterprise 11.5 (XI R2) assemblies are missing. The .NET SDK for BOE XIR2 has to be installed from the Enterprise installation CD. It is not available as a stand alone installer or MSI.
Finally, you've made note of trying to include the Enterprise assemblies with an EXE. BusinessObjects Enterprise is a web based application. SAP Business Objects does not fully support using the Enterprise .NET SDK in Windows applications. It may work, but any issues have to be duplicated in a web application before they'll be accepted for a possible fix. Additionally, since the XIR2 Enterprise .NET SDK is not available in an stand alone MSI it becomes quite difficult to manage deploying the SDK to multiple workstations.
Sincerely,
Dan Kelleher

Using time() function in multithreaded application

I am using time() function in a multithreaded application with NULL argument for getting current time.
Some time it's observed that we get a time one minute earlier than current time (3600 seconds).
Is there a problem in the usage of the function?
I am using expression : currenttime = time(NULL);
I had seen some people using following way - time(&currenttime );
Will above two behaves differently in multithreaded environment?
[I am using Sun C++ 5.5 compiler on Solaris 8]

How do you compare actual time against the time seen by your threads? If your threads are printing the value from time(2) to stdout, it's possible that you're seeing an artifact of thread scheduling and/or output buffering.
I really doubt that you have a concurrency problem, but anyway make sure that you include the -mt option on your compile line:
CC -mt blahblahblah...

Consuming a jms queue from a multithread application

Hi
Thank you for reading my post.
I have an application which shuld consume message of a queue.
my application is multithread and what i want to know is:
- How i can ask queue to remove a message after my thread finished its work with the message, by this way i can ensure that if my thread face an exception after it read the message my message will not lose.
- As it is multithread application, How i can ensure that a message is not delivered to two or more thread? is there any way to consume the messages in a synchronized way?
Will synchronized access restrict the performance?
Thanks

This is running in a J2DK environment. For my thread pool, I just copied one from a Sun tutorial on multi-threading then modified it. I creaed a seperate package with three classes. Here is my thread pooling package. I basically use a Vector to hold threads when they are not working. And you can set a limit as to the max number of active threads.

Workflows within the SAP environment

Hello,
for my diploma i'm evaluating the different workflow technologies within the sap environment. Therefor i set up a list with the different technologies and want to know if i'm missing something.
1) ALE
2) MDM Workflow
3) Business Workflow aka Adhoc Workflow
(CRM Workflow, SCM Workflow are synonym to the Business Workflow)
4) SAP Webflow aka SAP Workflow
(kind of a successor of Business Workflow)
5) Guided Procedures
6) Business Process Engine aka ccBPM
Are these the most used Workflows within the SAP environment or is something missing?
And what is the difference between SAP Business Workflow and SAP Webflow? Some source say these two are nearly the same, except the "web-capability" of Webflow...
btw: Sorry for posting this question in the Coffee Corner but its a farreaching area and i dont know which other forum it would fit better...
thx for replys
Matthias

Matthias -
Please be assured that there was no irony or sarcasm intended - if you can complete the evaluation task that you have set for yourself, it will not only be a wonderful achievement but also something that I'm sure many here would want to read and comment on.
The one thing to keep in mind - perhaps the most important thing - is that technological alternatives are never pursued rationally. Rather, they are generally pursued for the worst of reasons - someone's opinion of where "the market" is going at any given point in time.
So unless you can get an SAP "insider" to explain to you why SAP's workflow alternatives developed the way they did, you will not really have a complete picture.
Of course, it's also true that sometimes good things can happen for the worst of reasons, so perhaps the "inside" history of workflow at SAP is irrelevant.
The reason I'm going on about this is because I still don't think "the powers that be" at Walldorf have realized yet that the way to get pre-NW clients to NW200nx (NWDS, WDA, WDJ, GP, VC) is to get them to use regular old workflow first.
There is nothing in NWDS, WDA, WDJ, GP, and VC that can't be done in a pre-NW environment using a combination of user exits, BAdI's, BAPI's, and workflows.
And if SAP customers were to start using these older techniques to implement "integrated" and "process-driven" applications, then they would get into a "state-of-mind" that would make them much more confident of their ability to handle NW techniques, and much more aware of the benefits resuling therefrom.
As the old saying goes -
you've got to take folks from what they know to what they don't
i.e. you can't simply "shock and awe" customers into what you want them to start using.
Sorry to go on like this, but all these matters are tied up in the project you are about to undertake ...

Mixed sap environment linux and windows

Hello,
I have a question regarding a mixed SAP environment. At the moment we are running win 2003 and sql server 2000. 1 central instance and two dialog. Now somebody suggested to migrate the central instance to linux and maxdb and keep the windows dialog instances! I've never heard about an os mixed sap environment!
Is this common or do you know such environments? Please send your feedback and pro and cons to this suggestion!
Thank you in advance!
Does anyone knows how much the SAP migration service is?
Best regards,
Frank

Why migrate off of Windows O/S? I serve 1500 concurrent users along with 90,000 users on web services on commodity hardware ($20,000 per server), all running on Windows 2003 SP2 x64 with uptime of 99.9% per month.
Just wondering.
edit: To answer your question, SAP is an application level program which deals with different O/S via different kernels. However, from an SAP app to SAP app level, everything is done via TCP/IP pipes. Doesn't matter if that pipe is provided by Linux, Unix, or Windows.

Helloo,
Can anyone help me.
If u have informations about porting of J2EE Applications into SAP WAS , then plz help me.
I need certain J2EE Applications which are developed under J2EE 1.2 or lower than 1.3 (EAR files for conversion using convert tool).
Please help me with suficient help including links for downloading EAR files(J2EE 1.2 ) with help for porting.
I want to port one J2EE Application which is not developed under SAP WAS Netweaver (means not even under 6.2), completely out of SAP WAS environment.
How can i port that Application into SAP WAS?
What are the prerequisites for this?(I Have Netweaver Studio).
If any documents with helps available then help me with that links also..
With Regards

Hi UR,
BI-IP works on top of BI (datawarehouse). If you mean load data from non sap into BI and then plan with IP, it can be a good solution, if you mean plan data outside BI it is not possible.

Pro*c multithreaded application has memory leak

Hi there,
I posted this message a week ago in OCI section, nobody answer me.
I am really curious if my application has a bug or the pro*c has a bug.
Anyone can compile the sample code and test it easily.
I made multithreaded application which queries dynamic SQL, it works.
But the memory leaks when i query the SQL statement.
The more memory leaks, the more i query the SQL statement, even same SQL
statement.
I check it with top, shell command.

I changed source code which is from

the sample10 doesn't need to be multithreaded. But i think it has to work
correctly if i changed it to multithreaded application.
the make file and source code will be placed below.

sqlprc() is used to extract precision and scale

sqlnul() is used to reset the high-order bit of
the datatype and to check whether the column
is NOT NULL.
CHAR datatypes have length, but zero precision and
scale. The length is defined at CREATE time.
NUMBER datatypes have precision and scale only if
defined at CREATE time. If the column
definition was just NUMBER, the precision
and scale are zero, and you must allocate
the required maximum length.
DATE datatypes return a length of 7 if the default
format is used. This should be increased to
9 to store the actual date character string.
If you use the TO_CHAR function, the maximum
length could be 75, but will probably be less
(you can see the effects of this in SQL*Plus).
ROWID datatype always returns a fixed length of 18 if
coerced to CHAR.
LONG and

so you need to set a maximum. In this example,
it is 240 characters.

Hi Jane,
What version of Berkeley DB XML are you using?
What is your operating system and your hardware platform?
For how long have been the application running?
What is your current container size?
What's set for EnvironmentConfig.setThreaded?
Do you know if containers have previously not been closed correctly?
Can you please post the entire error output?
What's the JDK version, 1.4 or 1.5?
Thanks,
Bogdan

Is there any possibility to create ABAP Webdyn pro application in SAP 4.6C

HI All,
My client is in SAP 4.6C version want's to devlop some SAP ABAP webdyn pro application for their end user requirement.
Is it possible to do so if yes how ,they are ready to buy the required H/W and S/W component for the same,but they can't upgrade SAP to higher version at this moment.
As per my understanding WebDynpro for ABAP is dependent on current R/3 version. For that one should have mySAP ERP 2005 I guess.correct me if i am wrong .
Need your suggestion ..
How to achive ABAP webdyn pro application in SAP 4.6C Version.
Thanks,
Dev

Thanks!
Note 1098009 - Limitations for Web Dynpro ABAP
Solution
SAP System Prior to SAP NetWeaver 7.0 (NW2004s)
Web Dynpro ABAP is not released for official use in systems prior to SAP NetWeaver 7.0 (NW2004s).
Hope that helps.
Cheers,
Chris
edit - hmm hope I'm not taking a liberty quoting an SAP note ... If any mod's object - please remove quote - but I can't really see the harm in this case!

Cannot access WebDynpro application:com.sap.tc.webdynpro.services.exception

Hello gurus!!
I am trying to access the "Emergency address" from the LWE and I am getting this error "Cannot access Web Dynpro application: com.sap.tc.webdynpro.services.exceptions.WDException$DummyLocalizableTextFormatter@76829226". Could anybody please suggest what could be wrong with this action "Emergency Address"?
Thanks much for your help with this,
Maria Kutty Somori....

Hi Yugandhar/Siddharth,
Emergency address is the standard callable object for Execution that is part of the Standard Life and Work events. I have customized to reorganize the actions depending on our requirements and i have created a different folder structure and different order of execution of callable objects.
How do I fix this "cannot access Webdynpro application" error? Please suggest.
Thank you so much,
Maria Kutty Somori.....
