DB connect no data found is rfc connection required

Hi Gurus,
I want to retrieve data from oracle database, i have all the table with data in it, but through the source system i.e db connect it does not display any contents of the table, it says no data found, the installation was all done perfecttly fine, i can read the table fields but i am not able to read the data from the table. what could be the problem.
  Is an RFC connection required for this db connect to retrieve the data from oracle. or else what is the issue. Can anyone please help me out on this, I already posted long back on this still no reply on it. From the osss notes it allgives information about the intallation but it there is no data found then it does not give any information onthis. Can anyone please help me out on this.
Thanks,
Hem

Hi Hem,
You want to retrieve data from Oracle Database using BW and you are having a problem?
Try isolation technique to solve your problem.
Try to use third party softwares e.g. MS Excel. Retrieve data from Oracle using MSExcel. If MSExcel can retrieve data then you can conclude:
    a.) The network connection to Oracle is fine.
    b.) Oracle is up and running and is able to serve data from your specified table.
RFC Connection is not required. RFC is only useful for SAP to SAP communication. This connection uses a different technique and uses a different driver to communicate. SAP provided DB Connect Engine. A similar approach as what Microsoft's OLEDB is doing. This to make a transparent connection between various database systems. (whether MSSQL, Oracle, MSACCESS, SYBASE etc.)
As part of isolation technique, are you sure you are accessing the correct table? Try to access other tables. If you can access data of different tables then something is wrong with the table you want to access.
Have you check authorization issues? Are you allowed to extract data?
Hope I have helped. If I did, please grant points...

    Hi Gurus,
    I want to extract data from the oracle database, through db connect, when i edit the datasource and press the button display table contents, it says no data found.
      What could be the problem, i have created the source system properly, given all the information. seperatetly i logged into oracle and check the table contents it exists but does it not show up when i want to create a data source. Can anyone help me please,it would be of great help i'm trying to figure out what was the problem in oss notes also but still not found a solution any help will be of great help.

    Hi,
    Thanks for your reply, all the information in sap note as specified is set up, actually let me explain u in detail what we are doing,
       We have developed a livearchive prototype which will create a remote table on the remote database like oracle based on a infoprovider i.e either ods object or the infocube, we are archiving the infoprovider data into the rmote table, now the requirement is we want to extract, reload those table information back again into the infocube, so is it possible to do it, in the oracle database i can create views based on these table and also can view the data present in those tables, but when i want to extract through a datasource back again i do not find any data what could be the problem.
    Could u please help me out with this.
    Thanks,

  • Service Desk for VAR - RFC Connections to customers

    Hi all,
    I'm trying to implement Service Desk for a VAR provider, however, I didn't found until now how to connect customer systems to Solution Manager in the VAR provider site.
    I was able to create systems in SMSY automatically, as the Business partners and OSS users, but in SMSY the system has no Client (000,100,800) assigned and could not get it as no read RFC for system is maintained. Should this RFC be created using SAPSERV connection via marketplace (automatically or not) or using a simple direct SAPRouter connection to customer? anyone know how can I proceed or know some online documentation available?
    Manually maintain this connections could be very anoing as we have a lot of customers and systems.
    Thanks in advance for you help.
    Best Regards
    Pedro Rodrigues

    Hi Pedro,
    normaly you don't need those RFCs as a VAR, that's right. With the new note 1320545 you also get product versions updated from OSS into SMSY. However if you require all patch levels of your customers in SMSY to do MOPZ you need RFC or SLD connection. You can generate RFCs connections from the SMSY system client screen for ABAP instances. There is a button "Router information" where you can maintain your and your customer's SAProuter IP adresses. These will be included in the routstrings of the generated destinations. Of course this must be done manually for each customer system because SAP suport Portal doesn't know your customers passwords and routers.

  • RFC connectivity through JAVA

    Hello sir,
    I have create 1 java class file which connects to SAP DB through RFC connection.
    I have put sapjco3.dll,librfc32.dll,sapjcorfc.dll in to the folder windows\system32.
    Its working fine on windowsXP, but not working on Windows Vista and windows server 2003.
    its giving error as

    please tell me what configuration i have to do for vista and server 2003.

    Hi guys,
    please pay attention to the given infos on the JCo download site. It says:
    Note: Starting with JCo 2.1.4 and JCo 2.0.11, JCo requires the Visual Studio .NET C/C++ runtime libraries on Windows platforms.
    Starting with JCo 3.0.0, it requires the Visual Studio 2005 C/C++ runtime libraries. See SAP note [684106|https://service.sap.com/sap/support/notes/684106] for details on how to install them.
    Installing the VC redistributable packages from Microsoft will solve this issue.

  • Alternative to RFC connections - eCATT

    Hi Friends,
    I had created script1 with user1 and script2 with user2. I wanted to run both the scripts continuously using script1 with user1 and script2 with user2.
    The above case i am doing with RFC connections. I had created 2 RFC connections and i had mentioned RFC connections in the ScIPTs. I am able to run sucessfully.
    My customers don't want work in the above way beacuse so many connections will be there in SM04  transcation code. This will use lot of bandwidth and space.
    Is there any alternative to achive the above scenario. Can any one please help me on this .
    Regards,
    Mahendra

    I do not see the problem here, you need two uers in the target system to run your scripts (as you say in your first sentence) so whether they log on via RFC or any other way shouldn't matter as far as I can see.
    Maybe if you briefly explain wat both scripts are doing we can help you find a solution to that problem in a way that satisfies your customer.

  • WORKLOAD ANALYSIS (INTROSCOPE DATA) - Error when opening an RFC connection

    Hi all SDNers,
    Help is needed on error "WORKLOAD ANALYSIS (INTROSCOPE DATA) - Error when opening an RFC connection".
    This error occured on RCA -> Extractor FWK administration and go to managed system (PI) and from the log, i can see some extraction failed due to error message " Error when opening an RFC connection"
    consequently, JAVA performance data is not appearing in RCA -> workload analysis but work fine for ABAP and adapter engine.
    I've followed below notes and perform the troubleshooting step by step by still to no avail:
    Note 1332428 - Missing data in service sessions from BI/CCDB
    Note 1257308 - FAQ: Using EarlyWatch Alert
    Note 1274287 - End-to-End Diagnostics 7.0 EHP1 SP18 to SP27
    Note 1265070 - Diagnostics - Setup of Managed Systems
    Note 1010428 - End-to-End Diagnostics
    http://wiki.sdn.sap.com/wiki/display/SMSETUP/WorkloadAnalysis-Noapplicabledatafound
    steps that have performed:
    restarted agent
    enlarge RFC resource cap for solmandiag and none
    delete entire SID in SMSY and pull again from SLD, re-setup managed system
    restart PI system
    i've spent 2 days on troubleshooting this issue but lack of information in SMP and SDN, even in google.
    in table E2E_EFWK_STATUS and extractor E2E_JAVA_EXTRACTOR_IF, i see all WLI_ID ended with RC 96, MESSAGE = Error when  opening an RFC connection and LASTRECORDS = 0
    I strongly believe this is the issue that causing no applicable data found for JAVA data.
    fyi, we are on SOLMAN EHP1 SPS27.
    Any kind advise is most welcome.
    Thanks,
    Nicholas Chang

    Gosh! at last i found the solution!!
    I appreciate those who tried to help and i''m sharing the solution as i believe this is the purpose of SDN Forum and help others Netweaver Chap who facing the same problem:
    Problem faced:
    Extractor failed intermittently for WORKLOAD ANALYSIS (Introscope Data) due to error message "Error when opening an RFC connection"
    Due to the above error, performance data is not available in RCA workload analysis for J2EE engine.
    Possible Solution:
    1) Ensure both webadmin & SOLMANDIAG RFC working fine -> SM59 -> TCP/IP
    2) go to SE16 -> E2E_RESOURCES and change the resourcecap to 10 for SOLMANDIAG
    3) go to /smd/services -> Diagnostic System -> Advanced Setup -> Abap connectivity -> Connection Configuration and change server count to 10
    4) Restart webadmin (step 3 & 4 can perform in VA too)
    5) set gw/keepalive &  gw/reg_keepalive to value 0 in RZ11 (without reboot of instance)
    5) again go to SM59 -> TCP/IP -> SOLMANDIAG and put in the gateway host and gateway service correctly, don't leave this empty!!!! -
    > This is the main solution to solve intermittent failed RFC for extractor.
    Now, go back and monitor the extractor log and you should see no RFC error anymore and wait for 1 hour for the data to populate.
    Thanks!

  • An error occurred while reconnecting P: to \\JSERVER\Data Microsoft Windows Network: The network path was not found. This connection has not been restored.

    Almost every day when I open my computer I get this message:
    An error occurred while reconnecting P: to \  \  JSERVER\data Microsoft Windows Network: The network path was not found. This connection has not been restored.
    We then have to go through the process of resetting everything from start to finish just so I can connect to the server. There is no reason that we can find that causes this other than maybe windows updating every night. Any suggestions as to how to
    fix this? 

    it sounds like you have a network drive you are trying to map even though you are not logged in maybe in a script or task instead of backing up to :P backup to the share, make sure you have security set properly to run the task when not logged on.
    I assume you are running a backup of some sort as this is the backup forum..

  • SAP BO Data Services XI 3.2 - Cannot Handle Multithreaded RFC Connection?

    Hi Guys,
    Just want to ask for your inputs if Data Services cannot handle multiple RFC connection request to BW system?
    The scenario is:
    There is one BODI job using RFC connection and trigger the 2nd job at the same time and it happen that the 2nd job failed.
    Current version of SAP BO Data Services XI 3.2 that we are using is 12.2.2.1
    Thanks in advance,
    Randell

    Arpan,
    One way to get to the multiprovider data is to use Open Hub with a DTP that gets the data from the multiprovider and exposes it as an open hub destination to Data Services. With Data Services XI 3.2 we now fully support Open Hub where Data Services will (1) start the process chain to load the data (2) read the data when process chain ended and (3) notify Open Hub when done so that the data can be purged again.
    More info on Open Hub here : http://help.sap.com/saphelp_nw04/helpdata/en/1e/c4463c6796e61ce10000000a114084/content.htm
    But I will also look into the why we show the multiproviders when browsing the metadata, but get an error when trying to extract using the ABAP method (not via Open Hub). You could be right in your assumptions below and we might just need to hide the multiproviders when browsing metadata.
    Thanks,
    Ben.
    Edited by: Ben Hofmans on Jan 5, 2010 6:06 PM - added link to Open Hub documentation which references multiproviders as possible source.

    Hi Paulo,
    The message types was defined as configuration guide for only inbound in R/3. In the configuration guide I found only informations about receive the idocs in R/3 (inbound).  For inbound messages in R/3 system I defined BLAORD and COND_A, I tru to define teh same message types in outbound parametes in SRM,but the messages BLAORD e COND_A doesnt exists in SRM. Is there any documentation to make this?
    I was see the note too 641919
    Thanks,
    Gustavo
    Bom dia, Paulo!
    Tudo bem?
    Foi definido os tipos de mensagem de entrada BLAORD e COND_A no R/3 no tipo de parceiro do SRM. No configuration guide não faz menção na definição das mensagens de saida (outbound) no SRM, encontrei somente a configuração enviando o contrato do R/3 para o SRM. O que eu preciso e enviar do SRM para o R/3. Tentei definir os mesmo parametros de entrada no R/3 na saida no SRM, porem o tipo de mensagem BLAORD e COND_A não existe.

  • Step by step guide to create a RFC connection and data transfer

    hi
    could i get a step by step guide to transfer/read data from SAP and legacy system using the concept of RFC.
    Regards
    Shiva

    hi
    Here are the steps.
    SM59 Transaction is used for Connection Establishment with Destination.
    When you establish a connection to a client through a destination, the HTTP connection must first be entered in transaction SM59.
    There are two types of HTTP connection in transaction SM59: Call transaction SM59 to display the different RFC destinations.
    The HTTP connection to the external server (connection type G) and the HTTP connection to the R/3 system (connection type H) are different only in their logon procedures. Their technical settings are the same. To display the technical settings, double-click a connection.
    You can choose from three tabs. Under Technical Settings, you can specify the following:
    · Target Host: The host to which you want to connect.
    Note that if you are using HTTPS as a protocol, you have to specify the full host name (with domain).
    · Service No.: Here, you specify the port. The destination host must of course be configured in such a way that the specified port “understands” the corresponding protocol (HTTP or HTTPS). See Parameterizing the ICM and the ICM Server Cache.
    · Path Prefix: At the time when the connection to this destination is initiated, the system inserts this sub-path before ~request_uri.
    · HTTP Proxy Options: Here, you can configure a proxy for HTTP connections: You can determine the proxy host and service, as well as users and passwords for the HTTP connection.
    The tab page Logon/Security will be different depending on whether you have selected a HTTP connection to an external server (connection type G) or a HTTP connection to an R/3 system (connection type H).
    HTTP Connection to an External Server (Connection Type G)
    Choose the connection you want to use. You can choose from the following logon procedures:
    · No Logon: The server program does not request a user or password.
    · Basic Authentication: The server program requests a user and password. Basic Authentication is a standard HTTP method for authenticating users. When a user logs on to the target system, he or she provides a user ID and password as authentication. This information is then sent in a header variable as a Base 64-encoded string to the server, through the HTTP connection.
    · SSL Client Certificate: If you use client certificates for authentication, the client authentication is performed through the Secure Sockets Layer (SSL) protocol. In this case, you must also select the SSL Client PSE of the SAP Web AS that contains the relevant certificate for the authentication. The target system must handle the issuer of the SAP Web AS client certificate as a trusted system.
    Under Logon/Security, you can also activate SSL to ensure that HTTPS is the protocol used (if you select SSL, make sure that the correct port is entered under Technical Settings). In the security transaction STRUST you can determine which type of SSL client is used. (Getting Started with the Trust Manager, Trust Manager).
    The field Authorization for Destination has been implemented as an additional level of protection. We recommend that you specify a user and password for the RFC destination.
    HTTP Connection to an R/3 System (Connection Type H)
    Here, you can specify more settings for authentication in the target system.
    The settings under Technical Settings and Special Options are the same as for connection type G. Under Logon/Security, the connection type H has additional logon procedures. As with external servers, you can activate and deactivate SSL and specify an authorization.
    Because the target system is an SAP system, you can set the client and language for the logon as well as the user name and password. If you check Current User, you have to specify the password.
    The following authentication procedures are available: Basic Authentication, SAP Standard, and SAP Trusted System, and SSL Client Certificate.
    · HTTP Basic Authentication: Logon with user and password
    · SAP Standard: This procedure uses an RFC logon procedure. The RFC Single Sign-On (SSO) procedure is valid within the one system. The same SAP user (client, language, and user name) is used for logon.
    · SAP Trusted System: Trusted RFC logon to a different SAP system (see Trusted System: Maintaining Trust Relationships Between SAP Systems)).
    · SSL Client Certificate: The SSL protocol enables you to use client certificates for the logon.
    Type G/H (SM59)
    Timeout:
    When sending a HTTP request, you can use this parameter to specify the maximum response time for the connection.
    HTTP Setting:
    You can use the HTTP version to specify the protocol version of the HTTP request (HTTP 1.0 or 1.1).
    Compression:
    You can use this option to activate the gzip compression for the request body. This can only be activated in HTTP Version 1.1.
    Compressed Response:
    In the standard setting, the SAP Web Application Server sends the Accept Encoding field as a header field with the value gzip, if the application server can handle this compression. This notifies the partner that the caller can handle gzip decompression, and that the partner can send compressed data. If you want to prevent a compressed response being sent, choose the option No.
    HTTP Cookie:
    You can use this option to control the way received cookies are handled.
    You can specify the following for cookies:
    · Accept them automatically
    · Reject them automatically
    · Accept or reject them in a prompt
    · Use a handler for the event IF_HTTP_CLIENT~EVENTKIND_HANDLE_COOKIE to process the cookies in the program.
    · In the next section, you can read about the parallelization of requests.
    Thanks,
