Number of DIA work processes

Hello,
How do we decide the maximum number of DIA work processes (or total number of work processes including others like BGD, SPO, etc) that our server/hardware will support?
Secondly, we found that in the instance profile for one app server, parameter value for number of DIA is set as 30. However, in the SM50 for that instance, we only found 25 DIA work processes (no changes were made after system start in RZ03/RZ04). Any inputs?
Regards,
NK

When the instance is started, as many work processes as the sum of the following parameters are started:
rdisp/wp_no_dia
rdisp/wp_no_vb
rdisp/wp_no_vb2
rdisp/wp_no_enq
rdisp/wp_no_bt
rdisp/wp_no_spo
rdisp/wp_no_restricted
The sum of the parameters must be smaller or equal to the value of parameter rdisp/wp_max_no
From <http://help.sap.com/saphelp_nwpi71/helpdata/en/46/c24a5fb8db0e5be10000000a1553f7/frameset.htm>
Please let me know if your sum> rdsip/wp_max_no ?

  • Maximum number of dialog work process

    Hello gurus,
    Could you please let me know what is the maximum number of dialog work process that you can configure in an Netweaver system with ABAP 7.0 before considering to install a new application server to distribute the load?
    Thaks for your help,
    Best regards

    > Just one question, according to the following statement, can I think that I should estimate a usage of 1/4 CPU core by every dialog WP?
    No, this was just an example to make clear what I mean.
    > Do you know any SAP note that could help me to estimate the number of WP according to the load of the system?
    There is no such note and there can't be.
    You could have a system with e. g. 100 users where 10 of them do really produce load, the other 90 may just run a few transactions or do just nothing - so 50 WPs is too much. You could also have a system with 20 users where ALL are entering data all data and doing reporting and stuff so 20 WPs is too less. There may also be processes like ATP that use one background worprocess and spawn a number of dialog WPs you configure in the application. If you configure too few of them, the ATP run will run very log, if you configure too much, the system will be overloaded and slowing down. I can imagine dozens of other examples what may cause load or not.
    Because of that it's not possible to give a formular how many WPs to be configured for how many users.
    This is a tuning thing and needs to be estimated in the first weeks after a GoLive; watch the system, reconfigure, watch. Check ST03N and SM50/SM66 or book an early watch after some time, they have rough estimates and give usually good advises. Out of theory it's almost impossible to predict something.

  • What is the Max Number of Total Work Process that we can Have on  One C.I

    Hi,
    What is the Max Number of Total Work Process that we can have on a Single C.I
    Is there any Limit that We can only have Perticular Number of Total work process ?
    Or it is just Unlimited number of total work process
    Thanks & Regards
    Dan.

    from the system throughput point of view a rule of a thumb is:
    1 up to 4 sometimes 5 workprocesses per CPU.
    (one is used in Benchmarks where you have a very small number of transactions running with a small amount of database accesses)
    you can easily find it out:
    configure 4 WPs per CPU. If you have a number of WP's consuming nearly no CPU time you can reduce the number of WPs.

  • Stop DIA work process with PRIV mode.

    Hi,
    How to stop DIA workprocess with PRIV mode. by searching notes, I find it is possible to setl the max time and max number of the private memory.
    Kind regards,
    Masaaki

    Hello Masaaki,
    Before deciding whether to wait for the process to finish by itself or not, i would suggest that you find out the program which is causing the work process to go into PRIV mode. Once this is done, as your technical guys (ABAP) to analyse why this is happening (is the program logic inefficient and hence using so much memory etc).
    You have to note that (Dialog) work processes going into PRIV mode is not a healthy sign for the SAP application server.
    This is beacuse once the WP goes into PRIV mode it is not available to any other transactions, and we only have a limited number of work processes.
    Please make sure the parameters below are defined in RZ10 instance profile:
    rdisp/max_priv_time - used to define the maximum time that a work process can remain in PRIV mode. (After this the work processes is terminated and restarted). This is reasonable because beyond the time limit set, it is imperative to assume that the program using the work process is in efficient. (in case a program really needs that much time, it needs to be scheduled as a background job).
    rdisp/wppriv_max_no- this parameter defines the maximum number of work processes that can be in PRIV mode. Very useful.
    Also, make sure that a parameter ABAP/heaplimit is defined. This ensures that if a program eats up a certain amount of heap memory, the work process being used can be terminated.
    And finally please do check if your extended memory allocation is not big enough. the parameter em/initial_size_mb defines the fixed size of extended memory. Increasing this size only if you find that a lot of processes are frequently going into PRIV mode.
    Hope this helps.
    Regards,
    Prashant

  • Increase the number of background work processes for data load performance

    Hi all,
    There are 10 available background work processes in the BW system. We're doing some mass load to multiple ODS.But system uses only 3 background processes. How can i
    increase the number of used background work processes for new data load.
    I tried to change number of prosesses with RSODSO_SETTINGS. But no successes. Are there any other settings need to change?
    thanks,
    Yigit

    Hi sankar,
    I entered the max proc. number into ROIDOCPRMS. But it doesn't make difference. System still uses only 3 of background processes. RSCUSTA2 is replaced with
    RSODSO_SETTINGS in BI 7.0 and this trans. can only change the processes for data activation, SID generation and rollback. I need to change the process numbers for data extraction.

  • How to find out number of background work processe available in the system?

    Hi All,
    I have a FM that triggers a background job using JOB_OPEN, ABAP_SUBMIT and JOB_CLOSE. But the problem is if there are no background work processes available at that moment, it does not return error. Not sure whether the job is even scheduled!
    Is there a way to find out if there are any background work processes available in the system? I know a FM SPBT_INITIALIZE which gives info about dialog work processes. Is there any other FM similar to this which gives info about background wp??
    Regards,
    Shailesh

    your Job will remain in a queue by message handler. once workprocess is free, your job gets scheduled
    by the way, you can use the functionality used in FM TH_DISPLAY_WORKPROCESS_LIST to read the workprocesses
    the command which gets you the workprocess is:
    CALL 'ThWpInfo' ID 'OPCODE' FIELD OPCODE_WP_LIST
                      ID 'TAB' FIELD LIST_STATE_WPLST-TABL
                      ID 'CPU' FIELD LIST_STATE_WPLST-CPU.
    check how its written in include LSDEBF01, form SET_LIST_WPLST

  • Stop DIA work process with PRIV mode in my program

    Hello,
    I  write Program that display in the end an alv report and when i display it after same time my dia wp get in PRIV mode
    I search about it and I didn't find the solution but it happend only with my program this reject the memory parameter that cause the problem
    Thanks for your help

    Hi,
    >I think this not the problem because in the dev and the qa system it won't get in priv thanks
    >mode and the have the same value in the parameter ztta/roll_extension and the qa is the copy of the prod but 3 month old
    And these 3 months difference can perfectly explain why you have the problemn on production and not on QA.
    Private modes are generated usually because of badly designed programs (including standard ones...).
    ALV is not designed to display a huge amoiunt of data.
    Beware also of internal tables : Abap programmer usually abuse internal tables thinking memory is an unlmimited ressource...
    Just a few ideas.
    Regards,
    Olivier

  • Function called IN BACKGROUND TASK goes to work process DIA, not BGD

    I'm calling a function IN BACKGROUND TASK
    In SM50, I see it running in a DIA work process.
    I want it to run in a BGD work process.
    Can this be done?  If so, how?  If not, why not?

    Hi...
    It looks like, it will always run in DIA process and not Background process...I am not sure that we can change the work process
    Check the below link..
    http://help.sap.com/saphelp_40b/helpdata/pt/69/c24f864ba111d189750000e8322d00/content.htm
    What is written in the link is...
    "Background updates (CALL FUNCTION IN BACKGROUND TASK) represent a variant of remote function call that is synchronous with the end of a transaction (COMMIT WORK). In background updating, an update is run in another dialog work process that may be in the same or in another application server and R/3 System. Because such updates run in their own LUWs, they may start only after all critical updates have been completed. Otherwise, it would not be possible to roll back background changes in the event of an error in another update component. "
    IF you get the answer of whether we can change the work process then please let us know...

  • How to moniter the max quantity of used dialog work process in SAP system

    Dear Gurus,
    The quantity of Dia Work Process(DWP) of APP1 is: 16 (rdisp/wp_no_dia=16)
    The quantity of Dia Work Process(DWP) of APP2 is: 16 (rdisp/wp_no_dia=16)
    The quantity of Dia Work Process(DWP) of APP3 is: 20 (rdisp/wp_no_dia=20)
    The quantity of Dia Work Process(DWP) of APP4 is: 20 (rdisp/wp_no_dia=20)
    So the quantity of DWP in our SAP system is: 72 (=161620+20).
    We have 75 dialog users and many RFC callings via JCO method from J2EE system.
    I'm afriad the 72 DWPs will be run out of use someday.
    So I want to moniter the max quantity of used DWP every per hour to prevent the situation I mentioned above.
    Could you give me some suggestions?
    Thank you very much..
    Jason

    Hi Olivier,
      I really appreciate your help. You told me a very useful clew!
      As the method you told me, I have some questions:
      (a3) Do you restart your 'CI + 6 DIA' separately every week? Why did you do that?
      (a4) How to calculate 'CPU intensive time'?  For example, App server 'APS' was restarted on 8-10-2011 and stopped on 8-20-2011.
    There was a DWP(PID 557550) was created and activated on APS during this period(10 days). So If I add up each 'cpu time' of the task
    which 557550 executed, I can get the 'CPU intensive time' of 557550 (dispalyed in SM50). Right?
        In other words:
           DWP(PID 557550) finished task1: cpu time = 5ms  8-10-2011
           DWP(PID 557550) finished task2: cpu time = 4ms 
           DWP(PID 557550) finished task3: cpu time = 6ms  8-20-2011
         So the 'CPU intensive time'(Between 8-10-2011 and 8-20-2011) of DWP(PID 557550) is: 15ms (5ms4ms6ms). Right?
      (a5)Can we moniter the 'CPU intensive time' of DWPs in CCMS automatically? (I want to prevent the situation: The DWPs in our entire ECC are occupied.)
    Thank you!

  • How to statistic the rest dialog work process?

    Dear Gurus,
       Is there some method we can statistic the rest dialog work process in every ten minutes in our sap ECC prd system(ECC 6.0)？(I want to use the number to evaluate our SAP system's performance. Esp, at the business peak period.)
    Thank you!
    Jason

    Hi Jason,
    If I understand correct, you want to find out number of required work processes.
    You can find it, by using "ST02 -> Go to -> Current Local Data -> SAP cursor cache -> ID cache" path. On this table, you can analyze how many work processes are really running and how many work processes are waiting at the idle state.
    There is no time based values, about these statistics. These values indicate current stats.

  • How many work processes are recommended by SAP for 16 GB RAM

    How many work processes are recommended by SAP for 16 GB RAM ?

    This is the calculation for determining the number of work process according to the available memory  for the system.
    - Number of dialog work processes = RAM/256 (min 2, max 18)
    - Number of update work processes = RAM/768 (min 1, max 6)
    - Number of update2 work processes = RAM/1024 (min 1, max 3)
    - Number of batch work processes = RAM/1024 (min 2, max 3)
    - Number of enqueue work processes = 1
