    Ok, so what is the problem with that?
    You use the liveCache quite heavily (e.g. make lots of commits/changes) and the storage where you put your log-volume to is not quick enough to save the data.
    Either you fix the storage speed or you accept that your users might have to wait a bit longer for their application to save the data.

    These two things have no connection.
    A log queue overflow simply means, that sessions have to wait until the log queue is saved to disk before they can put new entries to the log queue.
    The log mode overwrite means: you don't care about data security and the ability to recover the liveCache from a backup.
    It's a setting used for throw-away database instances where it doesn't matter to loose data.
    It means that the database simply overwrites log entries that have not been backed up, when the log area gets filled.

  • SCM-- Live cache trace on

    Hi Experts ,
    Recently I have encountered one issue in my SCM system .There was trace on in live cache due to that system's performance very slow and CPU utilisation was more than 80%.
    I have checked in LC10 but i didnot find is trace on or off .I have checked all other standard live cache tcode as well but no luck
    Could you please tell me how to check live cache trace is on or off and where it stores the trace data at OS level.how to deal performance issue in live cache.
    Looking forward for your reply.
    Thanks,
    Arun

    In LC10 click on "liveCache: Monitoring". Then execute the very first node in the navigation tree ("Properties"). There you'll see some flags such as Database Trace on/off, Command Monitor on/off, etc.

  • SCM + Live cache

    Hi All,
    we are planning to install SCM Server version 5.0 with live cache server ,
    please help on connectivity with Live cache server
    In SCm 4 it is inbuit , does we require separate Live cache server for any SCm Version
    We are stuck on this ,
    please help
    Thanks & Regds
    Manish

    Hi Manish
    Yes, you would need a seperate server for Live Cache, we just completed installation of SCM 5.1 with LiveCache 7.7
    Install the Live Cache 7.7 as per the install guide (This is MAX DB not Oracle) or the version you need on a seperate server.
    You can do this install before you install SCM system, when you are in the install process of SCM system it will prompt you to enter LiveCache details.  Or if you wish you can do it later.
    IMP: There will not be any GUI to start and stop Live Cache alone, start and stop of Live Cache happens from SCM system using the transaction LC10.
    Once both systems are up and running, use LC10 from SCM system to complete the post install steps and complete the configuration. DO NOT GET CONFUSED WITH POST INSTALLTION PART in the Live Cache install guide, these should be done from SCM system.
    Backups: You need seperate backups for SCM and for LCA (Standard SAP naming convention for LiveCache Database)
    Hope this helps. Let me know if you understand this.
    Thanks

  • Hi having a problem upgrading SCM 4.1 APO Live Cache

    Hi I am new to SCM and I came into a project that was already started, I am doing a SUM upgrade and its at the upgrade of Live Cache I need to run the report /SAPAPO/OM_LC_UPGRADE_70 and perform all steps in section A. when I try to run the report it comes back "No shared library for the database with ID LCA" I checked LC10 and saw in the Settings that the database is still pointing back to the source system it was copied from. Like I said I walked into this in the middle the they are upgrading from SCM 4.1 to 7.0EHP3 on SQL 2012 and Windows 2012 so they built the 2012 Vm installed the Central services and when they installed the DB it was an attach / detach method and I installed the DB instance. Question should any of the file directories have come with the attach db there are no sapdb in the directories do I just install the live cache and that installs the maxdb and makes the directories /sapdb/ because I see them in the source system? I tried installing the live cache that came with the original system but it had errors.

    Hi All,
    I went ahead with Option 0 and it asked me for Kernel file and i provided the files.
    I checked logs in /sapdb/wrk directory and i see that Installation of SAP livecache finished successfully.
    From LC10 i gave database connection name (LCA) and clicked on live cache monitoring and it comes back with an error
    Name and Server : LCA - XXXXXXX (XXXXX = Server Name)
    DBMRFC Function: DBM_EXECUTE
    Command: dbm_version

    Thanks and regards,
    Vaibhav

    Hello Vaibhav,
    while using transaction LC10, the error 11 "tp error: Terminating. [nlsui0.c ...]" occurs. The user authorization with tp fails and the application server cannot connect to the liveCache.
    I assumed, that it's due to a library version mismatch, tp cannot use the liveCahe UNICODE libraries.
    Please check, that the tp call at the command line works properly. And a dbmcli call in the transaction SM49 with the tp options
    (dbmcli ::
    -d <LC-SID> -n <LC-servername> -tpp <profile> -tpi <system-SID>
    -tpc <connection - LCA/LDA> dbm_version)
    works also properly.
    I recommend you to update the liveCache client software on the Application server.
    If you've got access to OSS/Service Market Place, then please take a look at note
    649814 how to update the liveCache client software on the application server.
    < Please also review the SAP notes 847736 & 831108 > 
    Before the liveCache client version will be upgraded on the application
    server you can use the workaround by switching off the central authorization for the liveCache LCA/LDA connections:
    In transaction LC10, choose Integration and deactivate the option Central authorization, then save.
    If you are the official SAP customer, I recommend you to create the ticket to SAP on 'BC-DB-LVC' queue.
    Thank you and best regards, Natalia Khlopina

  • Live cache backup

    Hi Experts,
    I am beginner to SCM and Live cache technology.
    I have sucessfully installed SCM 5.0 and Live cache 7.6.29 on two different HP-Ux 11.23 servers.
    My first requirent is to take live cache backup. But there is no tape drive connect to any of the server,
    local file system assigned as  backup space, accordingly I have successfully taken online backup of SCM database by modifying entries like backup_dev_type to tape in  init<SID>.sap.
    Know I am facing a challenge to take live cache backup on local file system , infact dont know how to take online live cache backup.
    Another question is database manager gui is needed in unix environment, if yes please let me know the procedure how to configure this as In transaction lc10 upon double clicking database manager gui system generating error.
    Please help to solve the above two problems.
    Thanks & Regards,
    Maqsood Ahmed

    Hi Ahmed (no own SDN account? ).
    I'd like to make a few remarks on this:
    1. Backup to local filesystem w/o moving it to another location afterwards is next to useless. What happens when (when not if!), the local disk crashes? What backup can you use then?
    2. You can perform liveCache Backups from DB13C/DBACockpit after you've integrated the liveCache instance (DB59).
    3. If you like to administer the liveCache via DBMGUI - just install DBMGUI on your Windows Workstation and connect remotely to the liveCache. Actually this is the way how it was thought up.
    For detailed information how to work with liveCache I propose you check:
    The documentation [Backup/Recovery SAP Library - Database Administration in CCMS: SAP liveCache Technology|http://help.sap.com/saphelp_nw70/helpdata/EN/e9/dc1c3e46903b2ee10000000a114084/content.htm]
    The SDN Content on liveCache [https://www.sdn.sap.com/irj/sdn/livecache]
    The SCM Technology pages in the SAP Service Marketplace [https://service.sap.com/scm] -> SAP SCM Technology
    Good luck,

    Kishore Ch

    Hello Kishore,
    you could check the sizing of the liveCache data.
    * Report  /SAPAPO/TS_LCM_REORG_SNP has checks  of the SNP planning areas for superfluous objects.
    * Delete old/temporary APO data.
    * /SAPAPO/TS_LCM_REORG report checked TS superfluous objects.
    If you didn't create the planning versions, copy of planning versions & data load to liveCache, then create the SAP message to check your system on the question of the dataarea usage.
    If you have the long running APO transactions => performance of the SCM system has to be checked.
    If you have the bottleneck in liveCache & could not solve the case by yourself => create the SAP message to BC-DB-LVC and get SAP support.

  • Migration and Live Cache Doubts

    Hello,
    I need to migrate Windows 2003 Server 32-bit/MAXDB 7.6.0.035 for Windows 2008 Server 64-bit/MAXDB 7.6.0.035 and have doubts:
    1 - What is the best way to accomplish this migration? Via Sapinst? If there is another way, how?
    2 - In a note "1409895 - Windows 2008: TCP / IP communication MaxDB / liveCache is slow," reports to
    upgrade to a new version of SAP MaxDB / liveCache. If I upgrade to MAXDB7606_14-20001288.SAR (MaxDB 7.6.06.14

        Post output of the command:
          sdbregview u2013l
    3. u201CI don´t know if I need the Live Cache.u201D
    ->Why you was writing about the liveCache?
    ->Could you ask the customer what versions of the systems they have in the landscape?
    ->If you login to the SAP ECC 6.0, top menu: system->status
    What is the database of the system?
    4. Please see the SAP notes 1014782 and 960769, if the customer have SAP ECC6.0/MAXDB 7.6 on Windows Server 2003 32-Bit and want to migrate SAP ECC6.0/MAXDB 7.6 on Windows 2008 Server 64-bit version.

  • Live cache backup question

    Hello Experts,
    Iam new to Livecache and AP0  and was trying to understand the process of backups reason i need to perform complete SCM 7.0 systemcoopy . In past i have done system copies and well aware of the procedures .
    Here it goes Presently we are on SCM 7.0
    Question  :--> I see our Livecache is installed on one machine and AP0 on another machine. Iam not aware how Livecache
                           was integrated with AP0.
                           Iam trying to understand how to take backup of livecache and then restore the same in Target.
    In LC10
    LCA --> ProblemAnalysis --> Logs --> DBA History
    i can see that the live cache backups are in getting successfully everyday.
    I see that Backup Label as DAT_000000<xxx> and Backup Template as bac214<xxx>.
    Where can i see this Backup Template defined ( the path ) .
    Can someone provide an insight regarding the live cache backups.
    Checked SAP Note 457425 .
    --> After system copy how would i integrate Livecache and AP0 .
    Thanks in Advance.

  • Data fetch from live cache

    How can I retrieve data from live cache?This is in Demand Planning : SCM APO.
    Please suggest ways.
    Thanks & Regards,
    Savitha

    Hi,
    some time ago I worked on SAP APO.
    To read live cache, you first have to open a SIM session.
    You can do this as shown in this function module:
    FUNCTION ZS_SIMSESSION_GET.
    *"*"Local Interface:
    *"  IMPORTING
    *"     REFERENCE(IV_SIMID) TYPE  /SAPAPO/VRSIOID
    *"  EXPORTING
    *"     REFERENCE(EV_SIMSESSION) TYPE  /SAPAPO/OM_SIMSESSION
    CONSTANTS:
      lc_simsession_new       TYPE c LENGTH 1 VALUE 'N'.
    DATA:
      lt_rc                   TYPE /sapapo/om_lc_rc_tab,
      lv_simsession           LIKE ev_simsession.
      IF NOT ev_simsession IS INITIAL.
        EXIT.
      ENDIF.
    *--> create Simsession
      CALL FUNCTION 'GUID_CREATE'
        IMPORTING
          ev_guid_22 = lv_simsession.
    *--> create transactional simulation
      CALL FUNCTION '/SAPAPO/TSIM_SIMULATION_CONTRL'
        EXPORTING
          iv_simversion            = iv_simid
          iv_simsession            = lv_simsession
          iv_simsession_method     = lc_simsession_new
          iv_perform_commit        = space
        IMPORTING
          et_rc                    = lt_rc
        EXCEPTIONS
          lc_connect_failed        = 1
          lc_com_error             = 2
          lc_appl_error            = 3
          multi_tasim_registration = 4.
      IF sy-subrc > 0.
        CLEAR ev_simsession.
    *   error can be found in lt_rc
      ENDIF.
    * return simsession
      ev_simsession = lv_simsession.
    ENDFUNCTION.
    Then you can access the live cache.
    In this case we read an order (if I rememver correctly, it's a plan order):
    DATA:
      lv_vrsioid                  TYPE /sapapo/vrsioid,
      lv_simsession           TYPE /sapapo/om_simsession.
    * Get vrsioid
      CALL FUNCTION '/SAPAPO/DM_VRSIOEX_GET_VRSIOID'
        EXPORTING
          i_vrsioex_fld = '000'  "By default
        IMPORTING
          e_vrsioid_fld = lv_vrsioid
        EXCEPTIONS
          not_found     = 1
          OTHERS        = 2.
    CALL FUNCTION 'ZS_SIMSESSION_GET'
          EXPORTING
            iv_simid      = iv_vrsioid
          IMPORTING
            ev_simsession = lv_simsession.
      CALL FUNCTION '/SAPAPO/RRP_LC_ORDER_GET_DATA'
        EXPORTING
          iv_order      = iv_orderid
          iv_simversion = iv_vrsioid
        IMPORTING
          et_outputs    = lt_outputs
          et_inputs     = lt_inputs.
    If you change something in your simsession, you have to merge it back afterwards, so that your changes become effective.
    You can do this like that:
    * Merge simulation version (to commit order changes)
      CALL FUNCTION '/SAPAPO/TSIM_SIMULATION_CONTRL'
        EXPORTING
          iv_simversion                = lv_vrsioid
          iv_simsession                = lv_simsession
          iv_simsession_method         = 'M'
        EXCEPTIONS
          lc_connect_failed            = 1
          lc_com_error                 = 2
          lc_appl_error                = 3
          multi_tasim_registration     = 4
          target_deleted_saveas_failed = 5
          OTHERS                       = 6.
    I hope this helps...
