Parallel Processing for a single Package
Hi,
I have PKg1 that have mixture of For Each Loop container, DFT's and Seq containers and I want to run more than one thread for this package where i can process data in parallel.
Please let me know how i can create this using SSIS 2012.
Thanks,
Hi,
DFTs connected by precedence constraints and I want to run this package more than once (multiple threads) at a given point of time. is this possible? if
yes, please let me know how I can achieve this.
Thanks..
If the DFTs are connected then there will be absolutely no parallel processing. Running the same package in parallel most likely result in a lock. It depends how it is architectured, but with a RDBMS in default installation or files it is not going to fly.
When you have a DFT with say OLEDB destination each using its own connection, and they are not connected then each gets opened independently and thus allowing you to ingress data simultaneously.

UPDATE:
I ran a non-parallel Data Pump and just let it run overnight. This time it finished after 9 hours. In this run I set the STATUS=300 parameter in the PARFILE which basically echos STATUS updates to standard out every 300 seconds (5 minutes).
And as before after 2 hours it finished 99% of the export and just spit out WAITING status for the last 7 hours until it finished. The remaining TABLES it exported (a few hundred) were all very small or ZERO rows. There clearly is something going on that is not normal. I've done this expdp before on clones of this database and it usually takes about 2-2.5 hours to finish.
The database is about 415 Gigabytes in size.
I will update what the TRACE finds and I'm also opening a case with MOS. -
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

Parallel processing for increaing the performance
various ways of parallel processing in oracle especially using hints
Please let me knw if there exists any online documentation in understanding the conceptFirst of all: As a rule of thumb don't use hints. Hints make programs too unflexible. A hint may be good today, but might make things worse in future.
There are lots of documents available concerning parallel processing:
Just go to http://www.oracle.com/pls/db102/homepage?remark=tahiti and search for parallel (processing)
Due to my experience in 10g, enabling parallel processing might slow down processing extremely for regular tables. The reason are lots of waits in the coordination of the parallel processes.
If, however, you are using parallel processing for partitioned tables, parallel processing works excellent. In this case, take care to choose the partitioning criterion properly to be able to distribute processing.
If, for example, your queries / DMLs work on data corresponding to a certain time range, don't use the date field as partitioning criterion, since in this case parallel processing might work on just a single partition. Which again would result in massive waits for process coordination.
Choose another criterion to distribute the data to be accessed to at least <number of CPUs -1> partitions (one CPU is needed for the coordination process). Additionally consider to use parallel processing only in cases where large tables are involved. Compare this situation with writing a book: If you are planning to have some people writing a (technical) book consisting of just 10 pages, it wouldn't make any sense at all concerning time reduction. If, however, the book is planned to have 10 chapters, each chapter could be written by a different author. Reducing the resulting time to about 1/10 compared to a single author writing all chapters.
To enable parallel processing for a table use the following statement:
alter table <table name> parallel [<integer>];If you don't use the <integer> argument, the DB will choose the degree of parallelism, otherwise it is controlled by your <integer> value. Remember that you allways need a coordinator process, so don't choose integer to be larger than <number of CPUs minus 1>.
You can check the degree of parallelism by the degree column of user_/all_/dba_tables.
To do some timing tests, you also can force parallel dml/ddl/query for your current session.
ALTER SESSION FORCE PARALLEL DML/DDL/QUERY [<PARALLEL DEGREE>]; -
How to export a whole process for a single image.

Parallel processing for ABAP prorams in Process chain.
Hi All,
In one of the process chain, we have added the ABAP program. In Backend,the job is running as "BI_PROCESS_ABAP".
I just want to know, same like DTP, can we keep parallel processing for the ABAP programs also. Please suggest.
Thanks.Hello Jalina
Also check with BASIS if the memory allocated to run this program has not overflowed and the selections you have in your ABAP program is in small chunks and use variants to run them in parallel OR series
Thanks

Duplicate IR through parallel processing for automated ERS
Hi,
We got duplicate IR issue in production when running the parallel processing for automated ERS job. This issue is not happening in every time. Once in a while the issue happeing. That means the issue has happened in June month as twice. What could be the reasons to got this issue. On those days the job took more time comaredt o general. We are unable to replicate the same scenareo. When i am testing the job is creating IRs successfully. Provide me the reasons for this.Wow - long post to say "can I use hardware boxes as inserts?" and the answer is yes, and you have been able to for a long time.
I don't know why you're doing some odd "duplicated track" thing... weird...
So, for inserts of regular channels, just stick Logic's I/O plug on the channel. Tell it which audio output you want it to send to, and which audio input to receive from. Patch up the appropriate ins and outs on your interface to your hardware box/patchbay/mixer/whatever and bob's your uncle.
You can also do this on aux channels, so if you want to send a bunch of tracks to a hardware reverb, you'd put the I/O plug on the aux channel you're using in the same way as described above. Now simply use the sends on each channel you want to send to that aux (and therefore hardware reverb).
Note you'll need to have software monitoring turned on.
Another way is to just set the output of a channel or aux to the extra audio outputs on your interface, and bring the outputs of your processing hardware back into spare inputs and feed them into the Logic mix using input objects.
Lots of ways to do it in Logic.
And no duplicate recordings needed...
I still don't understand why the Apple-developers didn't think of including such a plug-in, because it could allow amazing routing possibilities, like in this case, you could send the audio track to the main output(1-2 or whatever) BUT also to alternate hardware outputs, so you can use a hardware reverb unit, + a hardware delay unit etc...to which the audio track is being sent , and then you could blend the results back in Logic more easily.
You can just do this already with mixer routing alone, no plugins necessary. -

Master data Reorganization Process for a single InfoObject
Hallo Experts,
mayby someone else had this problem bevor us?
SAP-BWProducion: Master data Reorganization Process for a single InfoObject (selfmade), other InfoObjects worked fine.
SAP BW 7.0 SP20 or 21
This element has daily attributes and the Q-Table has actual 180Mio entries. We startet reorganisation with 250Mio. entries.
Because of the daily loading, we cancel the batchprocess in the evening and started it again in the morning. This was fine for about 5 days. We elliminate 80Mio entries.
Our destination would be 80Mio entries left.
Whenever we run this feature now - in a process chain - no entries were deleted after 30 hours working, and there were no counting-stastics in SM50
Sequentielles Lesen
Insert
Update
Delete
The five days before, we saw Mio's of entries in this statistics.
We have checked the Q-table and there exist a number of records which have the same attribute values across several records and the date from - date to values of these records are in a row.
RSRV is fine and we checked note 1234411 Master data reorganization - Performance improvement.
There are no other notes helping us.
Please give us a solution-idea.
Thanks

Parallel processing for one large message
I have some troubles from messaging performance perspective.
Sender:ABAP Proxy
Receiver:File Adapter
I'd like use parallel processing for one large message.
And the file for receiver is needed to be one file.
Could you let me know how to set them ?
Best regards,
Koji NagaiHi
Can you elaborate your requirement more?
How are you trying to achieve parallel processing in XI.
Since you mentioned that the source is Proxy, there should be some trigger mechanism say selection screen, you restrict the values here and use append strategy in File and can execute the same.

Parallel Processing for BI Load
Hi All,
I have a datasource which i migrated from BW 3.x to BI 7 .
I am loading the data from datasource to ODS .
In the DTP -> Execute tab i can see only 'Serial Extraction
and processing of source package' . I Think because of this
i am not able to do parallel processing . I mean when i try to load data from PSA to ODS by DTP , the data is loading package by package ( It is not triggering parallel jobs while loading) .
Could you please advice me why i am not able to see
' Serial Extraction , Immediate parallel processing' in my
Execute tab of DTP .
Is there anything i need to configure at Datasource Level .
Please help me .
Regards
Santosh
Edited by: santosh on Jun 3, 2008 2:37 AMHi, check your extraction tab on the Datasource. I am pretty sure this has something to do with it. This is what it is on the help for DTP Processing.
Processing Mode
The processing mode describes the order in which processing steps such
as extraction, transformation and transfer to target are processed at
runtime of a DTP request. The processing mode also determines when
parallel processes are to be separated.
The processing mode of a request is based on whether the request is
processed asynchronously, synchronously or in real-time mode, and on the
type of the source object:
o Serial extraction, immediate parallel processing (asynchronous
processing)
A request is processed asynchronously in a background process when a
DTP is started in a process chain or a request for real-time data
acquisition is updated. The processing mode is based on the source
type. -
How to achieve parallel processing in a single request?
Hi all,
I have a method in a Session EJB that will perform some business logic before it returns an answer to the client. The logic it will perform is to collect data from the applications database and two external systems, before sending all data to a third external system to get a response and send it back to the client. Each external system is quite slow so I would like to do all the collecting of data concurrent, parallel processing. How should I handle this? I'm not allowed to create my own threads in EJB's. Can I use MDB in some way? To the calling client this should be a synchronous call...
Greatfull for any suggestions
Cheers
Anders =)Usually, the request is received by a component located in the web container, such as by an HTTP request (including Web Services). This component is able to start threads to allow parallel processing. Now, if for some reason the request arrives directly at EJB level and that you cannot move its receiver to web component, I think JMS is not a viable solution because you will switch to asynchronous processing and you have no way to make your EJB wait for the responses while preserving the client request (waiting implies programmatic life cycle management, which is forbidden in EJB container). Maybe a resource adapter (JCA) can bring a solution. A resource adapter acts as a datasource (a datasource is a specialization of a resource adapter) and thus it is a logical way to implement an adapter to an external, eventually non-J2EE, resource, as the name implies :) But I don't have enough knowledge in JCA to be sure of this.
Hope it helps.

Using Parallel Processing for Collection worklist Generation
We are scheduling the program UDM_GEN_WORKLIST in Background mode with the below mentioned values in the variant
Collection Segment - USCOLL1
Program Control:
Worklist valid from - Current date
Ditribution Method - Even Distribution to Collection Specialists
Prallel Processing:
Number of jobs - 1
Package Size - 500.
Problem:
The worklist gets generated but it drops lot of customers items from the worklist when the program is schduled in background using above parameters.
Analysis:
- When I run the program UDM_GEN_WORKLIST in online mode all customers come through correctly on the worklist.
- When I simulate strategy with the missing customers it evaluates them high so there is nothing wrong with the strategy and evaluation.
- I increased the Pacakge size to its maximum size but still doesnt work.
- Nothing looks different in terms of Collection Profile on the BP master.
- There are always a fixed set of BP's that are missing fromt the worklist.
It looks like there is something that I dont know about the running these jobs correctly using the parallel processing parameters, any help or insight provided in this matter would be highly appreaciated.
Thanks,
Mehul.Hi Mehul,
I have a similar issue now; since a couple of days, the WL generation fails in background mode. Although when I'm running it in foreground processing it's completed w/o any problem.
My question is that would you confirm that you did reduce the package size to 1?
so, your parameters are: nr of jobs: 1 and package size: 1
Is that right? Did it completely solve your issue? -
Parallel processing for program RBDAPP01
Hi All,
I am running this program RBDAPP01 daily after every 30minutes to clear the error I Docs (Status 51 Application document not posted) Status Message u201CObject requested is currently locked by user ADMINJOBSu201D when I run this job it only clears few Idocs because of the Status Message u201CObject requested is currently locked by user ADMINJOBSu201D Means when one Idoc is getting updated the second one tries to update the same time for same order, same customer, same material and same plant but different ship to party it finds locked and cannot be posted.
Can any one tell me what parallel processing is and will it help my case.
ThanksYou didn't specfiy which release you use so I can just give some suggestions:
Note 547253 - ALE: Wait for end of parallel processing with RBDAPP01
Note 715851 - IDoc: RBDAPP01 with parallel processing
