SMD Agents for Dialog Instances and Distributed Systems

We are planning to install SMD agents in our landscape.
Is it sufficient if we install SMD agent on the central instance Host to monitor all the instances ( CI + Dialog Instances)
Do we need to install SMD agents individually for all the Instances each for CI and Dialog Instances.
Also , If we have CI and DB on a separate host (Distributed Environment),  Do we need to install SMD Agent on DB host also.

Hello Tanuj,
Please refer to note 1365123 - Installation of Diagnostics Agents and check the attachments ( for this note.

  • SMD agent for VMW-based SAP systems

    SAP talents:
    We have hard time to configure SMD agents for VMW-based SAP systems.
    We have followed some SAP documents for non-VMW-based SAP systems, but seems that SMD agent cannot
    differentiate the individual system on VMW.
    Our SMD agent has no problem for non-VMW-based systems.

    Sorry to reply late because we have attempted a lot of  fixes but all failed
    For example, we have QAX, QAY and QAZ on VMW. 
    On Wily Introscope:
    1)  QAZ simply does not show up even we deployed/configured the agents as the procedure specified;
    2) under the node QAX, we see QAY's entry as a sub-entry.
    Does each SAP system need an agent OR only one agent is enough?  We have tried both ways  but
    seems not working properly either way.
    Please help, thanks a lot!

  • Differnce between central instance ,dialog instance and application instanc

    Hi all
    Please explain me what is central instance. what is it differnce betwenn the
    other instances like dilaog instance ,apllication instance.
    What is the exact use of having many instances ?

    Hi Sanjeev,
    First of all let me Clarify between Cental instance(CI)and Central Service instance(SCS). When you install NW04/NW04s systems on WIndows, when you open you windows console, you would first find the SID name that you have installed and when you expand this you'll find 2 instances. When you expand the first instance you'll find that there are message server and Enqueue server listed. This instance is called as Central Service instance or simply called SCS. You can look at the folder structure /usr/sap/<SID>/.
    Now the second instance is called as Central instance, when expanded you would see a SDM, a dispatcher and a server node. This is the instance which processes all your requests.
    Now answering your question about Dialog instance, When the CI is overloaded, i.e. your dispatcher is overloaded and your server is overloaded , you would install a dialog instance, which means that the database need not be installed for the Dialog instance and it can be on any system. While installing the Dialog instance it would ask you which Cental instance I have to refer, then you would be giving the necessary system to which you have created a dialog instance.
    Giving a graphical view,
    SID < J2E>
    <hostname>00  message server
                            enqueue server
    <hostname>01  SDM
    This is your one SAP system. Now you feel that this system is overloaded with lot of users, any there are many user who will be logging in again, so what you would do is install a dialog instance which would be referiing to J2E database but will have its own dispatcher and server0. SDM, message server and enqueue server are only one per systems.
    Now the dialog instance for J2E would look like this
    SID < K2E>
    <hostname2>01 dispatcher
    Dialog instance is mainly for load balacing, now you can access the database of J2E by typing a different URL i.e. of K2E and hostname2 but still accees the data of the J2E. The communication between Dialog and Central instance is thru message server.
    In case you find it difficult to push thru, please let me know..

  • There is no PSA for InfoSource 8ZCCA_O09 and source system BWPCLNT800 RSAOD

    Hi All:
    We make a Heterogeneous system copy of BW 3.5. from Solaris 9-Oracle 9i to AIX 3.5-Oracle 9i.
    We must have to rename the Logical System Name and during the Functional Testing the users configured the conections again in RSA1 transaction, then they start the
    testing phase but get the next error in the Monitor-Administrator Workbench:
    "@5C@ 28.02.2008 19:59:31 There is no PSA for InfoSource
    8ZCCA_O09 and source system BWPCLNT800 RSAODS 203"
    We can see that the errors refers to the old (BWPCLNT800) Logical
    System Name; during the configuration of the RSA1 they renamed the
    Logical System Name of the BW System to BWNIUSA800.
    We found the SAP Note 518426 but we are not sure about if we can
    execute it without affecting the system or the configuration.
    Some one Can help us ?.
    Best Regards

    Hi Reynaldo,
    this forum here is related to SAP NetWeaver Master Data Management. Your question seems to be related to SAP BI. Please raise your question in the [BI Forum|/community [original link is broken];, because I do not think that you'll find the experts to answer your question here.

  • No PSA for Infosource X and source system Y. Here Y is the flat file source

    We are facing an issue while transporting from dev s/m to quality. There is no PSA for Infosource X and source system Y. Here Y is the flat file source system this issue we are getting while transporting transfer rules.We are checked in OSS notes 518426. Its not helpful.

    You may also check SAP Note 861890 - ODS tables disappear during the upgrade -
    and activate all ODS Objects before the upgrade and run the program RSDG_ODSO_ACTIVATE.
    also that with Stack 14 an extended version of this program is available together with the
    Program RSUPGRCHECK. If errors occurs, consult also SAP Note 518426 and run transaction
    RSSGPCLA for the regeneration of the RSDRO_* Objects.
    Recheck whether you have Exported with correct parameters or not -- Try to Re Export the Same with all necessary objects .
    Try Note 524554 and 325525 also
    Hope it helps and clear

  • There is no PSA for InfoSource ZOUTNBR_TEXT_CC and source system PCFILE

    Hi All
    The above subject line shows the error.
    I have a custome data source in Development that is ZOUTNBR_TEXT which has a source system PC file.(flatfiles)
    when i transported all transfer structures and data sources from Development to Quality, only my transfer rules were not activated. but when i manually activated in Quality it throws with an error
    There is no PSA for InfoSource ZOUTNBR_TEXT_CC and source system PCFILE
    Please let me know how can i activate my transfer rules.

       We also faced the same issue while transporting from dev to QA. We raised a OSS, for which SAP has replied saying that there was some inconsistencies with the infosource and they have repaired the same in debugging mode. The root-cause for the issue is unknown. So they have not given any notes to us.
    But meanwhile we created a new data source and transported it. that worked fine.

  • SMD Agent for ABAP Only Systems

    Everything I have read states that the SMD Agent is only for JAVA Stack.  Then I read a post here stating to install the SMD on the ABAP systems.  Can anyone clear this up?  I have a mix of Java only, Abap only and dual stack systems.  Can anyone help clear this issue up for me?

    Hello Donna,
    SMD Agent can be installed on Java Stack, Java-ABAP Stack and ABAP Stack.  It is not there only for Java as it can be used with ABAP and Dual stack also.  Hope this answers the question that you have brought up.

  • Standalone SMD Agent for EEM won't connect to SLD

    I have installed a standalone SMD agent, which was configured properly (logs verify this) and starts up successfully, but I don't ever see it register in the SLD. Does anyone know of a guide which tells how to manage a standalone SMD agent? I want to get it connected to the SLD in Solution Manager so that I can use it as an EEM robot, but the connectivity so far is not working.
    For instance, if there is a way to get something like SM59 in an ABAP system on my SMD agent to change and test connectivity parameters, this may help.

    OK, thanks for the reference to the troubleshooting guide, I had not seen that before. Using it, I found the following procedure:
    How to check if the Diagnostics agent is registered in SLD?
    ␣ Go in SLD with the url: http://sldhostname:port/sld
    ␣ Logon with a J2EE user having the role SAP_SLD_ADMINISTRATOR
    ␣ Go in the section u2018Administrationu2019
    ␣ Click on link u2018Content Maintenanceu2019
    ␣ Select the subset u2018All with Instances and class u2018Diagnostics Agent Instanceu2019
    If the class u2018Diagnostics Agent Instanceu2019 does not appear in drop down list, No Diagnostics agent is registered
    ␣ In column Name of table, check if the Diagnostics agent is present.
    This procedure verified that my diagnostics agent is in fact in contact with the SLD, but for some reason, the agent does not show up in the SLD when I go to Home > Technical Systems, nor does it show up when I go to the EEM Administration screen > Robots > Check Agents.
    So I'll have to keep researching.

  • Best Practices for zVM/SLES10/zDB2 environment for dialog instances.

    Hi,  I am a zSeries system programmer who has just completed an IBM led Proof of Concept which demonstrated the viability of running SAP instances on SUSE SLES10 Linux booted in zVM guests and accessing zDB2 data via hipersockets. Before we build a Linux infrastructure using the 62 IFLs we just procured, we are wondering if any best practices for this environment have been developed as an OSS note or something else by SAP.    Below you will find an email which was sent and responded to by IBM and Novell on these topics...
    "As you may know, Home Depot has embarked on an IBM led proof of concept using SUSE SLES10 running in zVM guests on IBM zSeries hardware to host SAP server instances.  The Home Depot IT organization is currently in the midst of a large scale push to modernize our merchandising and people systems on SAP platforms.  The zVM/SUSE/SAP POC is part of that effort, as is a parallel POC of an Intel Blade/Red Hat/SAP platform.  For our production financial systems we now use a pSeries/AIX/SAP platform.
          So far in the zVM/SUSE/SAP POC, we have been able to create four zVM LPARS on IBM z9 hardware, create twelve zVM guests on those LPARS, boot SLES10 in those guests, install and run SAP instances in those guests using hipersockets for access to our DB2 SAP databases running on zOS, and direct user workloads to the SAP instances with good results.  We have also successfully developed cloning scripts that have made it possible to create new SLES10 instances, configured and ready for SAP installs, in about 10 seconds using FLASHCOPY and IBM DASD.
          I am writing in the hope that you can direct us to technical resources at IBM/Novell/SAP who may be able to field a few questions that have arisen.  In our discussions about optimization of the zVM/SUSE/SAP platform, we wondered if any wisdom about the appropriateness of and support for using zVM capabilities to virtualize SAP has ever been developed or any best practices drafted.  Attached you will find an IBM Redbook and a PowerPoint presentation which describes the use of the zVM discontiguous shared segments and the zVM named saved system features for the sharing of reentrant code and other  elements of Linux and its applications, thereby conserving storage and disk resources allocated to guest machines.   The specific question of the hour is, can any SAP code be handled similarly?  Have specific SAP elements eligible for this treatment been identified? 
          I've searched the SUSE Knowledgebase for articles on this topic to no avail.  Any similar techniques that might help us reduce the total cost of ownership of a zVM/SUSE/SAP platform as we compare it to Intel Blade/Red Hat/SAP and pSeries/AIX/SAP platforms are of great interest as we approach the end of our POC.  Can you help?
          Greg McKelvey is a Client I/T Architect at IBM.  He found the attached IBM documents and could give a fuller account of our POC.  Pat Downs, IBM zSeries IT Architect, has also worked to guide our POC. Akshay Rao, IBM Systems IT Specialist - Linux | Virtualization | SOA, is acting as project manager for the POC.  Jim Hawkins is the Home Depot Architect directing the POC.  I've CC:ed their email addresses.  I am sure they would be pleased to hear from you if there are the likely questions about what the heck I am asking about here.  And while writing, I thought of yet another question that I hoping somebody at SAP might weigh in on; are there any performance or operational benefits to using Linux LVM to apportion disk to filesystems vs. using zVM to create appropriately sized minidisks for filesystems without LVM getting involved?"
    As you can see, implementation questions need to be resolved.  We have heard from Novell that the SLES10 Kernel and other SUSE artifacts can reside in memory and be shared by multiple operating system images.  Does SAP support this configuration?  Also, has SAP identified SAP components which are eligible for similar treatment?  We would like to make sure that any decisions we make about the SAP platforms we are building will be supportable.  Any help you can provide will be greatly appreciated.  I will supply the documents referenced above if they are not known to any answerer.  Thanks,  Al Brasher 770-433-8211 x11895 [email protected]

    Hello AL ,
    first, let me welcome you on board,  I am sure you won't be disapointed with your choice to run SAP on ZOS.
    as for your questions,
    it wan't easy to find them in this long post , so i suggest you take the time to write a short summary that contains a very short list of questions.
    as for answers.
    here are a few usefull sources of information :
    1. the sap on db2 for Z/os sdn page :
    SAP on DB2 for z/OS
    in it you can find 2 relevant docs :
    a. best practices for ...
    b. database administration for db2 udb for z/os .
    this second publication is excellent , apart from db2 specific info , it contains information on all the components of the sap on db2 for z/os like zlinux,z/vm and so on ...
    2. I can see that you are already familiar with the ibm redbooks , but it seems that you haven't taken the time to get the most out of that resource.
    from you post it is clear that you have found one usefull publication , but I know there are several.
    3. a few months ago I wrote a short post on a similar subject ,
    I'm sure its not exactly what you are looking for at this moment , but its a good start , and with some patience you may be able to get some answers.
    here's a link
    good luck.

  • Installing Dialog Instance in heterogeneos system

    We have the Central Instance/DB Instance in the same server SUN Solaris O.S. and one Dailog Instance in SUN Solaris O.S., but we want to put one more Dialog Instance in IBM AIX O.S. I am not sure about how to deactive the automatic synchronization but we will have diefferente platforms.
    If we do not mount the filesystems from central to our new dialog if could be enought or we have to change something else in the profile parameters ?
    Thanks and Best Regards.

  • SMD agents for Solaris X86_64

  • RT Target Resources and Distributed System Manager

    Hello all,
    Does anyone know of some potential reasons why an RT target might not publish its CPU and memory usage?  This particular target is a cFP-2200 running a complete installation of FieldPoint 6.0.2 (RT 8.6) including System State Publisher.  For some reason I can't view the memory usage on this target and I haven't been able to figure it out.
    Thanks in advance,

    Hello Hillman,
    Thanks for your reply!  I sort of
    figured that this one would go by the wayside and not be answered. 
    Actually, I'm not using RTSM; I'm using the Distributed System Manager
    - It's a relatively new tool that ships with LabVIEW RT 8.6.  In my
    humble opinion, I find it to be much superior to the RT System Manager
    in its own way.  The only downside, really, is that you can't log with
    it natively, but there are ways around that.
    got some great suggestions.  I definitely was using the correct IP, I
    could target it with LabVIEW because I loaded my application on there,
    and I didn't get any boot errors when I connected.  You're absolutely
    right, too, that the CPU is always maxed out at 100%.
    guess I was perplexed because, one moment I could see the resources in
    DSM (is that acronym valid yet?), and after I reloaded the software
    from scratch, I could see lots of variables on the target, but for some
    reason the system resources weren't showing up.  After no one jumped on
    the question, I went back to tweaking various settings and realized
    that I hadn't rebooted after enabling VI Server.  In fact, I didn't
    think that VI Server would be the issue and hadn't really thought of
    checking there.  My reasoning followed that, if all of the other
    variables showed up, surely it wouldn't be VI Server, but that fixed it.
    I definitely appreciate your getting back to me, though.

  • JSPM  for Dialog instance

    I could see links for using JSPM for deploying SPS for central java instance hosts. Need to know, how Java dialog instances are updated?( Java+ABAP dialog instances are installed in separate hosts).Should we follow the same process.? It is little new to me.

    Hi Raj,
    if SPAM could be used for both Hosts
    in ABAP it doesn't matter which application server you are loggin into for applying support packs. because, when you're applying support packs, things are getting stored in database. so no matter if you go to CI or app server.
    In case of Java all deployment archives is stored in CI. and also you will notice that SDM process (who is responsible for deployment) only present in CI not in dialog instance.
    Dialog instance just gives the additional server processes for handing additional loads.
    Hope this clarifies your doubt.
    Regards, Debasis.
