How to synchronize two applications system

HI,
I work witj Designer 9i, in a Non-versioned Repository. I create a copy of an application system on the same repository.
I would like to know if there is some mechanism that will synchronize the two application system copies. What i want is how to automate the replication of any modification I made to the copy, in the original application.
Thanks for your help,
Malika

Hi Roel,
I want to do this because in our organization the repository is non versioned, and we want to make copies for the application system in purpose to sure that only Data modeler and DBA will access it. The developers can't update it. In the original application system we will replicate the changes and then developers go on with their Treatment modules.
Thanks for your reply ,
Malika

    Of corse I have an idea, but not good!
    If you know the database stucture then copy data from one to another.
    Open 2 connections: one to source and one to dest.
    And:
    String sql = "SELCET * from mytable1";// from source
    string sql2;
    Statement st1 = connSrc.createStatement();
    Statement st2 = connDest.createStatement();
    ResultSet rs = st1.executeQuerry(sql);
    while(rs.next()){
    sql2 = "INSERT INTO mytable1 ('field1', 'filed2') VALUES ("+
    "'"+rs.get(filed1")+"',"+
    "'"+rs.get(filed2')+"'"+
    st2.executeUpdate(sql2);
    // the destination was cleared before this: DELETE FROM mytable1 WHERE 1
    This is a mysql sample without processing the errors.

  • How to synchronize two fpga DIO?

    Hi!
    I am using two FPGA 7962R (flexrio) with each 6581 terminal board in PXIe-1082 chassis. My problem is how to synchronize two 7962R digital output with PXIe-1082 chassis backplane signal Dstar* or Clk10 or DAQ signal.
    Actually I tried the synchronization with one DAQ counter clock (confering 'Gen Dig Pulse Train-Finite_NI. vi') , and get the signal PXI-Trig0 by source terminal and target terminal connection, but that one does not work properly. Especially, one trigger signal in HOST to set the starting point of each FPGA (7962R), make error by depending on the trigger signal value(Hz value and Timed loop clock in FPGA vi). It was very tricky and not reliable. (I am attaching figure files as explaining the situation)
    My aim is simply to use two FPGA 7962R Digital output as one FPGA, for controling X-axis, Y-axis with each FPGA, while able to change each FPGA (X-axis, Y axis) digital output value. Because the synchronization is not correct, X,Y axis control with Two FPGA currently is out of target if I use simply while-loop design in HOST and timed-loop design in FPGA vi. What is correct design to synchronize the two FPGA 7962R without using PFI line, only with PXIe-1082 chassis backplane signal and able to change the digital output value? Please let me know any idea for HOST vi, FPGA vi programming.
    Many Thanks

  • How to use bsp application SYSTEM for session handling.

    Hi All,
    We are implementing OCI.We have a few BSP applications that are called by standard ITS application.I need to destroy session at server side when the browser is closed for that..
    I copied the pages session_default_frame.htm and session_single_frame.htm from bsp application SYSTEM into my application and made necessary changes.
    I need to pass one url 'HOOK_URL' (this is related to OCI) from starting page of application to final page.
    Now suppose earlier there were two pages in my application page1.htm and page2.htm , so i was able to pass the HOOK_URL from page1 to page2 but after adding the two pages from SYSTEM application , i can pass the HOOK_URL from session_single_frame.htm  to page1.htm
    Page session_single_frame.htm:
    Page attributes:
    hook_url     TYPE     STRING (AUTO)
    OnRequest:
    navigation->set_parameter( hook_url ).
    but cant pass it from page1 to page2...what additional code is required?
    page page1.htm:
    Page attributes:
    hook_url     TYPE     STRING (AUTO)
    onRequest:
    navigation->set_parameter( 'HOOK_URL' ).
    the above code was working fine until i added the two new pages to my application.
    Hope i was able to explain the issue properly.
    Thanks,
    Anubhav.

    Hi,
    Let me describe the steps i have taken oncw again:
    1)Copy page session_single_frame and session_default_frame from SYSTEM application and changed the name in
    DATA: target_page               TYPE STRING VALUE 'session_test.htm'.
    to
    DATA: target_page               TYPE STRING VALUE 'mypage1.htm'
    2)Addes a page attribute HOOK_URL of type string (AUTO) to session_single_frame.htm .
    3)Added the line
    <i n p u t  t y p e="hidden" na m e ="HOOK_URL"  v a l ue = "< % =  hook_url %>">
    to page1.htm so that hook_url is passd to page2.htm (page2.htm has a page attribute HOOK_URL of type string and auto).
    The hook_url in page2.htm looks like:
    "http://sapupd.mycompanyname.com:8002/sap(cz1TSUQlM2FBTk9OJTNhc2FwdXBkX1NSTV8wMiUzYXJUaHBOdE1VZDdhWkVTa3hYZGtPTXRxY1NBTWo3VlAwN3NWQ2c2REYtQVRU)/bc/gui/sap/its/bbpsc02/?~OkCode=ADDI&~Target=_top&~Caller=CTLG&~sap-syscmd=NOCOOKIE&~client=200&~language=EN&~HTTP_CONTENT_CHARSET=utf-8";
    The problem is that after the page is submited , a blank page comes up .
    On closing this blank page the "Endig user session" window comes.
    Please help
    Thanks,

    You can easily embedded one Web Dynpro component within another.  This is exactly what you are doing when you use ALV.  You can do the same thing with your components.  I suggest that you start be reading the help section on cross component usage:
    [http://help.sap.com/saphelp_nw70/helpdata/EN/a7/1d8b412bb5b35fe10000000a1550b0/frameset.htm|http://help.sap.com/saphelp_nw70/helpdata/EN/a7/1d8b412bb5b35fe10000000a1550b0/frameset.htm]

  • How to Synchronize two methods or more methods

    You're being really ambiguous. You could "synchronize" those methods by adding the synchronized keyword to their method signature, in which case they will implicitly lock on the object they belong to. That's what most people will think you mean when you say synchronized. Is that what you meant? Or did you mean what BDLH was thinking in that you wanted to lock something, then do 1,2,3,4, then unlock it? That's something different. Be specific!

  • Two applications systems with the same DB

    Hi,
    is it possible to have two Oracle applications systems on the same DB ? I mean for exemple two e-business suites (Oracle applications) each one with a different instance of the same database ( DB version 9i and OA version 11.5.9).
    Many thanks before.

    Not possible,certified or supported,anyways you cannot have two SIDs for the same DB can you?

  • How to synchronize two Event Dispatcher threads?

    I have two applications running in the same jvm. The flow should go like--
    a) First application (A1) has a swing window containing componets like buttons, text boxes etc.
    b) On click of this button, Event Dispatcher thread (T1) , calls the other application (A2).
    c) The second application A2, creates a swing window using EventQueue.invokeLater method and in the mean time Thread T1 should wait for this new A2 window to get some results from the database.
    Is it possible to stop thead T1 in between without freezing the GUI components of application A2.
    Thanks

    I think what tjacobs01 is getting at, is that there is only one Event Dispatcher Thread per JVM. So your question does not make sense. If there really is two EDT threads, then you are dealing with inter-process communication (since there would be two JVM processes, one for each application).
    It sounds like there is only one JVM, one EDT and two instances of a java.awt.Window. You probably think of the window == an application. In that case, you can probably solve your problem by executing the DB access (the long-running task) in the doInBackground() method of a SwingWorker.

  • How to connect two BW systems to one ECC system?!?

    Hi Experts!
    We want to connect our ECC system (P11) to multiple SAP BW systems. Therefore we made a system copy of our productive BW System (P81) and create a new second BW System (T81). When I want to restore to connection to the P11 in the T81, Iu2019ll get the following error message:
    u201CDie Verbindung CA wird im Quellsystem P11_001 als Verbindung zum BW T81CLNT001 genutzt.
    Soll diese Verbindung im Quellsystem gelöscht werden? Nach erfolgreicher Löschung wird der Anschluss wiederholt.u201C
    In English this message means something like that: u201EThe connection CA is used as a connection to the BW T81CLNT001 in the source system. Should this connection be deleted in the source system? This connection can be repeated after successful deletion.u201D
    Now I ask myself: How can I connect our new BW System to our ECC System, without destroying the old connection to our productive BW system?!?
    Have anyone of you an idea how we can handle this issue?
    Thanks in advance!
    Regards, Alex

    Hi
    This happens because of RFC settings duplication as your new BW system is copied from Old one.
    First you restore the Production system connection by deleting the existing RFC.  But this will delete the new connection you have created ( that is what your dialog message is saying) 
    Basically , before creating new connection you need to delete some table entries manually , then you can connect both the system to your same source system
    Please find the link below where I mentioned the table names from where you need to delete duplicate entries manually.

  • How to combine two applications with different workspaces in APEX

    Hi,
    Can anyone help out in merging two applications with different workspaces in APEX 3.2 ?
    Thanks in advance,

    Hello Satya,
    >> I am Satya …
    Please take one more step to help us and update your forum handle to something friendlier than user123… Thanks.
    >> Can anyone help out in merging two applications with different workspaces in APEX 3.2 ?
    This is not a trivial task.
    You didn’t mentioned if both workspaces sharing the same APEX instance, or they are on two different instances (machines). I believe the latter is a pre-condition to a success.
    First you need to remember that importing an APEX component, like a single page, is possible only to the same application that it was exported from. This is still valid if you have the same workspace on two separate APEX instances – one is an import of the other (which makes it an identical copy). Still, the application ID must be the same, or you’ll get the following error: “This page was exported from a different application or from an application in different workspace. Page cannot be installed in this application.”
    You can’t simply manipulating the export file, if the two workspaces are sharing the same APEX instance, as all workspaces on the same instance shares the same APEX metadata files, and you’ll receive a “unique constraint violated” error messages. That means you can’t import one application into the workspace of the other, even if you are using a different application ID.
    As far as I can see, the only viable way of doing an application merge is to have two identical workspaces, on two separate APEX instances. The two applications should share the same application ID, although this parameter can be changed in the import file. You should export the page in one application – on the first instance – and import it into the other application – on the second instance.
    You should also make sure that the exported page ID doesn’t exist on the target application, otherwise it will be replaced by the new imported page. Also, if the imported page include references to shared components that are not defined on the second application, it might also pose a problem.
    As I said, this is not trivial. The benefits are mostly depend on the amount and complexity of the pages you want to merge. If they are not many, and simple, you should consider just re-creating them on the target application. If they are very complex, the merge might fail anyway.

    Arie.

  • How to synchronize two USB webcams (each at 30fps) for a combined 60fps video? Three for 90fps?

    Hello All,
    Multiple-Camera Lab Application: How-To?
    Exploring a loose-synchronization for cameras, low resolution, B&amp;W=gray video capture, that may require up to 200fps, laboratory application.
    Frames would be recorded serially, from 1_frame/10msec at 100fps to 1_frame/5msec at 200fps.
    Consecutive frame-to-frame intervals do not need to be fixed at 10msec, they may vary a lot +/-50%, are non-critical.
    Video recording may last up to 1_minute maximum real time (no sound recording needed at any time).
    Specs say a generic USB2.0 webcam can record up to 30fps.
    And USB2.0 is a half-duplex serial protocol.
    Using two or more webcams in parallel, focused on the same scene, may yield a composite video capture at multiples of 30fps.And much lower price than a single dedicated high speed camera.
    Ultimately all frames have to be assembled -in sequence- into one big video recording.
    Any comments, any ideas? Did anyone try this?
    Thank you,
    Dan

    Hi,
    Sorry I am not much help about this. Creative webcams aren't built to work that way.

  • How to make two Application Modules share the same entity cache?

    Hello everyone, I am using JDeveloper 11.1.2.3.0
    I have a little problem in my application through using two AppModules that contain also same ViewObjects. So to be clear one VO is declared in two AppModules. When I commit the view by using AppModule1 and then go to another page that uses the same VO but from AppModule2, I have to commit again, even through the row is previously stored in the database.
    I understood that this came because different AppModules use different entityCache for database communications.
    I am asking if anyone knows any option on how to sync the entity caches from the two appmodules, or how to make them use the same entity cache.
    Thank you

    You can make a copy of the app and give it another name, but it will use the same settings files no matter which you open. Settings aren't stored in the app, but in your Preferences.
    Firefox, being a Windows derivative, might have the capability to use "Profiles" where you'd set it up different for each profile. I don't use Firefox, so I don't know if that option exists.

  • How to synchronize two NI9215 DAQmx cards?

    Hi there,
    I'm using two NI9215 DAQmx cards (4ch simultaneous sampling analog inputs) in a chassis type cDAQ-9174.
    Since I need to aquire 8 channels simultaneously I've two NI9215 cards.
    My question is how do I configure these cards to be synchonized?
    I'm using LabVIEW2009 SP1 Dev. Suite
    Thanks for answers!
    Solved!
    Go to Solution.

    One of the beautiful things about CompactDAQ is that you can put multiple modules of the same time (Analog, Digital, etc.) into the same task and they are automatically synchronized.  So, to synchronize the two modules, create one Analog Input task and reference the channels as "cDAQ1Mod1/ai0:3, cDAQ1Mod2/ai0:3".  This will automatically synchronize the two modules together.
