Swaps in PXA Buffer (abap buffersizw)

Hi Experts
In my production server lot of swaps in PXA buffers, yesterday only I increased PXA buffer size 240000 to 270000, but still I am getting swaps in that PXA Buffer (ABAP/BufferSize), any body give the how much memory I have to increase to that respective buffers, what is the solution to over come  this swap problems in PXA buffer
Best Regards

Hello,
Increasing the size of buffer swap space depend on hardware configuration of your system.
First check how much total paging space is allocated in your system.
Depending on your hardware configuration you can increase size of  buffers.
you can check current value & SAP default value in your system...
check system load in your system. Sometimes due to more load swapping occurs...
If this continuously happens you need to check for all buffers.
You can check in ST02, which buffers are causing more swaps...
take action acc to that...

  • Swaps on program buffer

    Hello all,
    I am trying to figure out why we started having many swaps in program buffer on ST02 and I found this on history that is quite strange.
    It appears that Free storage is bigger than available storage!! Few months ago that we had the same issue, we started having again hundreds of swaps on this buffer. Could someone explain what this Free storage shows and probably suggest how to find the root cause of the issue?
    Thanks!

  • PXA Buffer

    Hi *,
    I have an ECC6.0 System with 32 bit Architecture WIN Server 2003 Enterpreise with 8 Gig Memory.
    I have reserved a fixed memsize of 2 Gig for MSSQL Database
    I have "installed" Zero Admin Management by setting PHYS_MEMSIZE = 5120
    /3GB and /PAE is set in boot.ini
    My buffers have a total volume of ~ 1Gig
    PXA has 720 000 KB.
    When I increase PXA System restart ist no longer possible undependent of the size of PHYS_MEMSIZE
    Do you have an idea why PXA is limited in that way?
    best regards
    Thomas
    Edited by: Thomas Volkwein on Jan 4, 2008 3:19 PM

    the problem is that virtual address space on 32-bit is limited by 2(3 if /3GB is active in boot.ini)GB - see SAP notes 110172, 552209, 546361. Shortly to say, if you want to increase PXA buffer, you have to reduce some other buffers, however you should also keep in mind that PXA is buffer with contiguous structure, i.e. the process must have this free contiguous space.
    720MB should be enough for PXA buffer in 99% of production systems.
    If you see high paging value or bad hit ration you must review the quality of buffer.
    using 64-bit platform (SAP note 996600) will help you to avoid such problems

  • Swaps in Program Buffer

    Hi Gurus,
    When should we tune buffer parameters?.
    For example: Swaps for program buffer are 90,000. In which case we have to tune the program buffer?. I know there is no threshold or thumb rule for swaps in SAP system. What will be the base point to tune buffer parameters to reduce swaps?
    Thanks in advance

  • Swapping and Database Buffer Cache size

    I've read that setting the database buffer cache size too large can cause swapping and paging. Why is this the case? More memory for sql data would seem to not be a problem. Unless it is the proportion of the database buffer to the rest of the SGA that matters.

    Well I am always a defender of the large DB buffer cache. Setting the bigger db buffer cache alone will not in any way hurt Oracle performance.
    However ... as the buffer cache grows, the time to determine 'which blocks
    need to be cleaned' increases. Therefore, at a certain point the benefit of a
    larger cache is offset by the time to keep it sync'd to the disk. After that point,
    increasing buffer cache size can actually hurt performance. That's the reason why Oracle has checkpoint.
    A checkpoint performs the following three operations:
    1. Every dirty block in the buffer cache is written to the data files. That is, it synchronizes the datablocks in the buffer cache with the datafiles on disk.
    It's the DBWR that writes all modified databaseblocks back to the datafiles.
    2. The latest SCN is written (updated) into the datafile header.
    3. The latest SCN is also written to the controlfiles.
    The following events trigger a checkpoint.
    1. Redo log switch
    2. LOG_CHECKPOINT_TIMEOUT has expired
    3. LOG_CHECKPOINT_INTERVAL has been reached
    4. DBA requires so (alter system checkpoint)

  • Reset or Bypass SQL Buffer ABAP Program

    Hi,
    How to bypass or reset the use of the buffer table in an ABAP program with the purpose of evaluating their performance access. I can not change the program because it is in production.
    Thanx.
    Diovani

    Hi ,
    I am giving you the SAP standrad help  comments here  as prescriblely :
    FROM clause
    Specifies the database tables from which the data in the selection in the SELECT clause is to be read.
    Syntax
    ... FROM [<tab> [INNER]|LEFT [OUTER] JOIN] <dbtab> [AS <alias>]
                                   [ON <cond>]
             [CLIENT SPECIFIED]
             [BYPASSING BUFFER]
             [UP TO <n> ROWS]
    You can read a single table <dbtab> or more than one table, using inner and outer joins to link tables with conditions <cond>, where <tab> is a single table or itself a join condition. You can specify individual database tables either statically or dynamically, and you can replace their names with an alternative <alias>. You can bypass automatic client handling with the CLIENT SPECIFIED addition, and SAP buffering with BYPASSING BUFFER. You can also restrict the number of lines read from the table using the UP TO <n> ROWS addition.

  • How to understand buffer swaps

    In SAP training materials, it says that buffer swaps occur when buffer content is deleted from the buffer and is replaced by other content. It's no relation at all to the swapping mechanism on OS level.
    I am confused about the source and target of buffer swaps. For example, when buffer swaps occur on program buffer(PXA), where will the data in program buffer be put, physical memory?, and where does new data come from? SAP buffers locate on share memory, belong to virtual memory, but virtual memory is the summary of physical memory and OS swap space(or OS paging file). I just remember that extended memory resides on physical memory, don't know whether sap buffers reside on physical too.
    For swapping on OS level, I think it's page exchange between physical memory and swap space which locates on disk. Is it right?
    Please advise on how to understand buffer swaps and OS swapping. Thanks so much.

  • ST02 SWAPS reported what does that mean.

    Hi Team,
    In ST02 of one of the system all the apps I see many SWAPS column with value and in red color, what it mean
    program, swaps with 11,349
    generic key with 68
    single record with 1,002
    Thanks
    Vijay

    Hi,
    ST02 is the buffer monitor that offers instance specific information that provides:
    1. status of different buffers instance wise
    2. information on memory usage instance wise
    3. information on table buffering at instance level
    Swapping takes place for two reasons:
    1. not enough 'free space left' in buffer for buffering new objects
    2. buffer has run ouf of 'free directory entries' that can be contained in one buffer area *
    Directory entries diminish the available size of the buffer, independent of their usage.
    Swaps are to be avoided, as are all other situations leading to lines shown in red in the ST02 display.
    Please note that Buffer swaps occur when buffer content is deleted from the buffer and is replaced by other content. It has no relation at all to the swapping mechanism on OS level.
    An example with a more practical outlook to swapping observed:
    Use transactions SM50, ST03N and ST02 to identify the problem.
    a. Using SM50 you might find high number of work processes accessing tables related to ABAP sources and status as 'Load Program'. This hints to a problem with Program [PXA] buffer.
    b. In transaction ST03N, you find unusually high 'load and generation time' causing even higher wait times. Threshold for load and generation time is typically 50 ms.
    c. In buffer monitor i.e. ST02, you find many swaps [typically more than 10000 swaps happening per day for program buffer]. Check on hit ratio [value below 95% is typically poor]. This indicates problem. Program buffer could be small!!
    If program buffer is small, it means that workprocesses require to reload program loads over and over again which causes bad system performance.
    Resolution: Increase program buffer size/ check on load and generation times/ hit-ratio increases/ system response time also lowers down!! : )

    Shabnam.

  • Swapping increase

    Hi All,
    my DEV system is running very slow and Swap size increased.
    while i run the following command for reset the buffer.
    /$SYNC This resets all buffers of the application server
    /$CUA This resets the CUA buffer of the application server
    /$TAB This resets the TABLE buffers of the application server
    /$NAM This resets the nametab buffer of the application server
    i did restart the system after run above command then ST02 went to normal swap while swap is
    increasing once again. I am send you ST02 status and Parameters and please have a look and
    guide me.
    while here window server 2003 with ECC 6.0 SR3 and oracle 10.2.
    I am waiting your respons.

    Swap rate for Export/import buffer is almost 120 swaps per day.
    Moreover 2 instance are running on this server having 4gb RAM Capacity.
    i have installed ECC 6.0 version sap system,O/S RHEL4 ,64 BIT .
    25 users working regularlly on the system.
    plz tell me to what extent i have to increase the size of these parameters so that swap rate comes down.
    regards

    Hi,
    Beacuse you are unsing 64bitYou can increase the size of the rsdb/obj/buffersize  parameter for larger size:
    rsdb/obj/buffersize = 60000
    rsdb/obj/max_objects = 15000
    this should provide you with the solution.
    For  more information read this note:702728
    Also you should know that swaps doesn't necessary  meam BAD.
    What should interesting you is the hit ratio.
    Reagrds.

  • Program buffer

    Dear all,
    We are using R/3 4.6C on HP-UX 11.0 with Oracle 9.2.0.5 and kernel sup. package 2039. On this server we have two production R/3 instances. Server has 8 CPUs, and 8GB RAM, with defined swap of 20GB.
    Can You PLS explain:
    - we have more then 92000 swaps on the program buffer in one week only on one instance which has more users and more transport activities;
    - Should I increase the parametar abap/buffersize (currently 500000kB)? And how much should it be?
    - ipc/shm_psize_06 should it be = -10 and ipc/shm_psize_02 = -10?
    I'm not sure what are the steps to increase the program buffer, and how much should it be increased?
    Thank you in advance.
    Regards,
    Ruzica

    Hi Ruzica,
    Have you seen OSS note 103747 which describes the recommended parameter settings for 40B and above ?
    It looks like you may need to increase it slightly (profile parameter abap/buffersize). The note suggests that the system can tolerate 1,000 swaps per day but you are seeing over 10,000 per day.
    In our busiest SAP system, R/3 Retail, we have a PXA buffer size of 600Mb and we experience between 1000-2000 swaps per day. However, it depends what mix of modules you are using in the system. This greatly influences the programs that are loaded.
    You mentioned that you have two instances on the one server. Is this the CI and one application server for the SAP system or is it two separate SAP systems (i.e. separate SIDs) ?
    If the two servers are part of the same SAP system, it may be worth looking at how the users are being distributed across the two servers.
    Regards,
    Gary

  • Memory parameters settings as per RAM and swap size

    Hello Experts,
    We have installed the newly SAP systems (Solman 7.1, ECC6 EHP 5, and CRM EHP1), below is the platform-
    OS - Linux x86_64
    RAM - 20 GB (ECD ABAP and solman (ABAP+JAVA)) and 24 GB (CRM ABAP).
    swap size is twice of RAM.
