Parallel Processing on the Server

I am creating a Java web application that demands some intense and time-consuming server-side processing. Therefore, once the user makes his request (which involves submitting a file), I want to do 2 things: 1) redirect the user to a confirmation page and 2)perform the processing and send an E-mail of the results to the user. Of course, these should be done in parallel.
I am not exactly sure how to go about doing this sort of thing given the request/response model in servlets/JSPs. I've considered bouncing the reqest around various servlets to get this done, but I am not sure exactly how that would work. I've also considered spawning a thread, but I am not sure if I want to do that inside the web container.
Any suggestions are greatly appreciated. Thanks.

I have never worked with MDBs either. But I don't see why the servlet couldn't send the file (as an array of bytes representing the actual data, or as a string that holds only the name of a temporary file where the servlet stored the data) to an MDB which would do that.
Here's a link to an MDB tutorial, since you've worked with EJBs I expect the terminology should not be a problem:

Dynamic parallel processing of the same object using asynchronous method

Hi,
Please can anyone help me?
I have to send the same DMS document to several agents for parallel processing. The number of agents is not known until runtime. Each of them should process the document and at least change the status of it. In next step I check if he has changed it.
I use dynamic parallel processing of subworkflows. Key task of this subworkflow uses standard method of object DRAW - DOCUMENT.EDIT (standard transaction CV02N) which is asynchronous. The task is finished by event DOCUMENT.CHANGED.
During the parallel processing the appropriate number of workitems is generated. However, when the agent who processes the document as first completes his workitem the event DOCUMENT.CHANGED is generated and all parallel workitems are completed, even those of other agents that were not processed yet.
Any help would be appreciated.
Thanks.

Hi all,
The process is used to approve incoming invoices. Each scanned invoice is attached to a DMS document and than sent to one or several agents in parallel. People from several departments can approve the same invoice for instance energy or mobile phone costs. We have no HR module fully implemented. Each agent may write some remarks and has to sets the document status to either approved or rejected. This status is temporary therefore the others see the original status for approving.
The process of incoming invoices was implemented by SAP consultants in 2003 on 4.6B and now runs on our 4.7 system. Now new company was established running on a new SAP system ECC 6.0 and our accountant department and some agents will deal with invoices in both systems. Therefore, the process should appear the same or at least very similar. The majority of the old process was realized by programming while I would like to use workflow features that are available now and reduce the programming part.
As I see, I will have to choose one of the solutions that Arghadip suggested.
I wonder if there is a possibility to use asynchronous method and control the end of each work item by means of u201CComplete Work Itemu201D or u201CComplete executionu201D Conditions. I have never used them and I do not know how they work and what condition to use. Maybe program exit might be used as well. While controlling the agents I think I will have to do some programming anyway because the work item can be finished by a substitute too.
Thanks for your help.

This message is used to carry data between the BlackBerry handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.

I have a client with a BlackBerry Pearl 8110. It was (is) configured to receive email from a Microsoft Exchange Server via his Outlook account. I have uninstalled the Desktop Manager and re-installed ensuring the computer transmits his email via the Re-Director. All settings in the Desktop Manager are correct. The phone was working fine for over 5 years. Now he is getting emails both on his phone and in Outlook saying:
This message is used to carry data between the BlackBerry handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.
I have verified that his phone is not attempting to perform the Enterprise Activation process by checking :
Options > Advanced Options > Enterprise Activation.
He does however have a Service Book entitled "CMIME"
How can I resolve this issue?

Is the user needing the Redirector service?
Step 1: If you're not using Redirector or Enterprise, you should uninstall Desktop Manager and then reinstall it using the BlackBerry Internet Service option.
Step 2: On your device, go to: Options > Advanced > Service Book, and delete all service books for [Desktop]

Hi,
Anything updates?
In addition, this issue may also because your client didn't have CA certificate of your domain. Please make sure that your client has CA certificate.
Besides, the error "The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server" may be due to that the default maximum transmission unit that NPS uses for EAP payloads is 1500
bytes. You can lower the maximum size that NPS uses for EAP payloads by adjusting the Framed-MTU attribute in a network policy to a value no greater than 1344:

Parallel processing in the same work center

Dear Guys,
There is a routing sequence in which some 2-3 operations will occur parallely & those operations will belong to a same work center,How to map those operations in the routing,do i need to maintain parallel processing ,if so then how to go about

Parallel Sequence
Definition
A linear sequence of operations that is parallel to a sequence of operations in the standard sequence.
Use
A parallel sequence enables you to process several operations at the same time. A parallel sequence is carried out at the same time as the corresponding section in the standard sequence. It is a special form of overlapping operations.
Integration
You can create parallel sequences in routings and rate routings. You cannot create them in reference operation sets or reference rate routings.             Creating a Parallel Sequence
Call up the sequence overview.
Choose Edit ® New entries.
The Choose Sequence Category dialog box appears.
Select Parallel sequence and press Continue.
The Sequence Details screen is displayed.
Enter the necessary data.
Select Operation overview to create operations for the parallel sequence.
so particularly in your case

Parallel Processing at the time of confirmation

Hi Gurus,
During confirmation of production orders / collective orders (T.Code u2013 CO11 / CO12 / COHV) or through REM Backflush done in Repetitive Manufacturing (T.Code - MFBF), material components get locked, for processing when multiple users are transacting either confirmation of above orders or MM-IM transactions in parallel.
Eg. Goods Receipt for components in stores cannot be made during confirmation by planning production scheduler and vice versa.
As a result, transaction of Goods Receipt making cannot be executed getting error message u201CUser lockedu201D.
Please suggest us how parallel processing can be carried out on same materials simultaneously like working on CO11, CO12, CO1P and MIGO for the same material. System should allow processing parallel with minimum execution time.
Any SAP notes available for this?
Any one faced such issue and resolved this, please share.
Thanks in advance,
Regards,
Srini

Hi Srini,
Normally this should not be a big problem, since it takes just a short time to process automatic goods movements related to production order confirmation (backflush GI, and GR).
But if in your reality it is, then SAP offers a decoupling concept, which results in posponing those movements, and perform them en-mass at a more convenient time when it less disturbs (like after normal office hours). Look in the link for full details:

AIR vs. Flex: image generator as a background process on the server

I am running into problems with an image generator running on
a headless server.
When I start up the server, it launches my java app. It reads
a list of report definitions from the data base. For each report,
it spawns a thread. Each thread launches my Flex application in a
browser window.
Flex draws the data in charts. Each time data is pushed to
the flex application from the java server side, Flex calls a remote
java method to save it's image to a file. This file sits in a
directory where it can be viewed in a regular old html page.
The problem is really the automated aspect. I want to have
this chart generated every few minutes as a .png file. It works
perfectly fine on my localhost machine, but the server deployment
is so far not working, I think because it is headless. We have
firefox installed on the server. Is there no way to launch it as a
background process to draw these images? Should I turn this into an
AIR app (I've never done anything with AIR up to this point) to
make it run more easily in the background?
Java programmers all seem to think that running an image
generating process in a web browser window on the server is "bad
practice". So I think I am thinking maybe I should turn it into an
AIR app. I'm not sure though how to deploy AIR apps though. Can
they go in a .war file?
If someone has any ideas about this or if going AIR is the
wrong approach here please let me know. Thanks!

Not explicitly, as far as I know.
But you could always run it and then hide its window using Cmd+H, or the menu command "iCal" -> "Hide iCal". Click its dock icon to make it visible again.

Parallel processing of the IDOCs through the program RBDAPP01

Hello All,
We are prcoessing the inbound IDOCS using the program RBDAPP01 by scheduling but this processing is taking lot of time to process the IDOCs.
Please let me know how do we improove the performance of this program RBDAPP01 by making use of
parallel processing of IDOCS?I read some documentation in this forum but not understand clearly.
Please give some info regarding this who have already done this requirement earlier.
Regards

Hi,
Thanks a lot for your quick reply just by giving the package size it will initiate parallel processing?
in our partner profiles we have setting to trigger through back ground only.
How to use parallel processing tab in the selection screen of the program RBDAPP01?

Thanks.

Oracle uses shared memory and most UNIX utilities do not properly report Oracle process memory usage due to double counting of shared memory. Are you getting errors? If not, I suspect the figures reported by TOP are not correct.
What platform are you on?
Any errors in alert.log or in the lsn background dump destination trace files?
How is overall system performance?

Question on parallel processing using the STARTING NEW TASK keyword

I have the following code in a program on my development system:
call function 'FUNCTION_NAME'
    starting new task ld_taskname
    performing collect_output on end of task
      exporting
        pd_param1       = ld_param1
      tables
        pt_packet       = lt_packet.
You'll notice in the code above I left out the following part of the function call:
DESTINATION IN GROUP group
In my one-server development system the topmost code executes fine, but I'm getting a 'REMOTE FUNCTION CALL ERROR' when I execute this in a multi-server Q&A system.
My question: Is the missing 'DESTINATION' keyword required in order for this technique to work in a multi-server environment or is it optional keyword? I made the assumption that since it worked in my development environment that without the 'DESTINATION' addition the system simply used the current logged on system to start the new processes.
Any input appreciated.
Thanks,
Lee

Hi Lee,
Just take F1 help on CALL FUNCTION key word and go to the variant
CALL FUNCTION func STARTING NEW TASK task
              [DESTINATION {dest|{IN GROUP {group|DEFAULT}}}]
              parameter_list
              [{PERFORMING subr}|{CALLING meth} ON END OF TASK].
This gives you very clear information about this Key word.
No one would give you better information better than this, i hope
Cheers

The parallel process for mrp.

hi exports
we plan to do the scope of planning for the total planning as a background job.
while doing that system ask for the parallal processing for mrp
what is customize step and procedure to do the parallel process for mrp.

Dear Raj,
With the help of parallel processing procedures, you can significantly improve the runtime of the total planning run.
To process in parallel, you can either select various sessions on the application server or various servers.
Parallel processing runs according to packages using the low-level code logic:
The work package, with a fixed number of materials that are internally defined in the program, is distributed over the individual servers/sessions. Once a server/session has finished processing a package, it starts processing the next package.
If a low-level code is being planned, the servers/sessions that have finished must wait until the last server/session has finished its package to avoid inconsistencies. Then the next low-level code is processed per packages.
The parallel processing procedure is switched on in the initial screen of total planning.
Activities
Define the application server with the number of sessions that can be used:
If you want to define various servers for parallel processing, enter the server with the number of sessions.
If you only want to use one server, but several sessions, enter the application server and the appropriate number of sessions.
Further notes
Parallel processing shortens the time required for calculation, however, it cannot shorten the database time as the system still only operates using one database.
The Customizing Transaction is OMIQ

How can I implement parallel processing feature in Oracle 9i?

I need to load (and transform) millions of data from Table1 to Table2. How can I speed the process using parallel processing. The server has 4 processors (running on Win2k Advanced server).
Can anyone guide me what are the exact steps required to enable parallel loading. I've already partitioned Table1 into 4 parts.

insert /*+ PARALLEL(8) */ into table A select * from table B ;
or alter table A parallel 8 ;
or alter session enable parallel dml ;

Parallel processing issue withing same server

hi,
i need to perform parallel processing withing same server using work processes available in same server.
suggest if this can be accomplished and explain the design if possible.

Hello Venkata,
You can achieve parallel processing by using CALL FUNCTION .... STARTING NEW TASK <task name>.
In this case function module runs in asynchronous mode without stopping calling program.
For more details you can refer following link:
