Lock objects,Editor lock difference ?

What is the difference between lock object and editor lock

Hi,
Editor Lock : This is to lock a program created by User 1 from editing by any other User. Say for eg. User "XYZ" has created a program and he doesnt want anyone else to edit/modify that program, then he can put Editor Lock so that no one else other than "XYZ" user would be able to edit/modify it.
Lock Object : Consider an example, where two Users say User 1 and User 2 wants to book railway ticket. Only 1 seat is remaining. The ticket information is updated in table ZTICKETS. This table can have tickets only from 1 to 10.
Now User 1 and User 2 approaches two different reservations counters and ask for the same train ticket. Now the table is Locked for User 1 and the ticket information is updated in ZTICKETS table so that the other User should not get the ticket. Otherwise two persons would be alloted the same ticket. So the table locking from simulatneous updates can be achieved through Lock Objects.
Best regards,
Prashant

  • Unable to create Instance with Object Editor and Attachment Pattern

    Hi Experts,
    I created a simple entity service with some attributes and a document reference.
    I also configured an object editor pattern and assigned a attachment pattern. The created object editor works as long as I don't attach a file. But if I attach a file and want to save it I get an error message "cannot create"
    In the default log.trc I have some entries
    Cannot read associated instance with MOF ID 105D8E0C4F02D45AFFD5B9D6A09EFB7A of MOF Layer 2 for (6DC24B80F6004CDBF4FA6C560AEDD33C,<null>)
    and
    refPackageM1(com.sap.ip.bi.sdk.dac.olap.query) failed RepositoryDBMemory. Using generic one.
    I configured the j2ee engine according the tutorial "Integrating KM with CAF UI Patterns"
    So what is wrong?
    Best regards Manuel

    Hi,
    From the stacktrace I assume that the following happens (please correct me, if I'm wrong):
    <b>*</b> Some time based event mechanism sends an event to your custom event handler code. That code is execute in some system context.
    <b>*</b> Your handler uses the RF API to create a collection. All this is perfectly OK. Here my assumptions end, the next steps are solid facts.
    <b>*</b> Within the RF all property filters are informed that a resource is about to be created. One of the filters is trying to obtain a lock from a system provided Locking Service.
    <b>*</b> That service refuses to grant the lock, telling that system users are not allowed to do so.
    Most proably you cannot do anything to solve this problem by yourself. When I ran into the same Exception once, I could avoid to have my code run in a system thread. Well you might try to do the same.
    Otherwise please open a customer message and complain about the restiction in the locking behaviour.

  • Front Page Object Editor

    Hi,
    I have added frontpage add-in and under tools it is showing three options SAP xMII Object...,SAP xMII Configuration Menu....., SAP Script Assistant.....
    SAP Script assistant is working fine but SAP Object is opening but couldn't show any templets in the windows. When I clicked Login and entered username and password it could not connect to server all.
    I was wondering some where it is not getting which server it has to connect.
    Can some please tell me where to specify the server name in Object editor.
    Thanks,
    Srinivas.

    The standalone version does not use FrontPage server extensions, in fact only the FrontPage software itself uses the extensions to communicate to/from the IIS box.
    The fundamental difference between the standalone and embedded version is how they communicate with xMII for namespace browsing query and display objects.  The standalone prompts the user for machine name and port, whereas the embedded one uses the application title bar string from FrontPage itself to parse the server path, which is why
    server\c$ doesn't work, nor does F:\server\path - it needs http://servername:port or http://servername.  This only happens within FrontPage when you do either File...Open Site or File...Open Web (depending upon version) and physically type http://servername in the input box that shows up at the bottom of the dialog box.
    Once FrontPage connects to the webserver the application title bar will read something like "Microsoft FrontPage - http://servername:port" and the Folder List tree header will say "http://servername:port".  Then and only then will the embedded one work like you want it to.

  • View Object Editor in JHS 10.1.2 does not save any changes....

    Hi,
    When I did exactly as the JHeadstart Tutorial says, I noticed that
    in JHeadstart 10.1.2 with JDeveloper 10.1.2
    JHeadstart does not save any changes I make in the View Object Editor
    of the Application Structure File Editor !!!
    For instance when I change the Width property of an Attribute from 60 to 5
    it changes to 5, but when close the View Object Editor
    and reopen it again, the Width is back to 60...
    Even when I click the button "Validate the Application Structure File" before
    closing the VO Editor....
    What do I do ??? Is the only solution to edit the XML file
    or something like that without using the VO Editor ?
    Or is there a better solution ?
    Does it maybe work in an older version of JHeadstart ?
    If so, where is the older version available for download ?
    Thanks,
    Eric Joosse

    Eric,
    How did you leave the JHeadstart VO editor?
    The changes should be saved when you click the OK button in the VO editor itself, but they are not saved if you click Cancel, or the little cross in the upper right corner, or leave it open while going back to the Application Structure File editor. That's because it's a standalone editor (you can also find it when right-mouse-clicking the VO in the Model project). The icon in the Application Structure File editor is just a quick way to get to it.
    Hope this helps,

    Hello Sumit
    This is most probably the result of metadata corruption on runtime.
    A possible workaround for this situation is:
    Undeploy all the metadata DCs of all the CAF applications you have
    deployed (these are the components which names end on "/metadata", excl.
    caf/core/metadata and caf/tc/metadata (which are part of CAF itself)).
    And then deploy the CAF applications again.

    Désiré

  • JDev 10.1.3 EA Studio Edition - View Object Editor java glitch

    Just thought I'd mention what appears to be a glitch - under the "java" section of the View Object editor, the checkbox for generate "Custom Java DataSource Methods" does not appear to function. Selecting it does not add the custom datasource methods in the View Object class.

  • Error using Object Editor pattern

    Hi Gurus!!!
    I am creating a composite application using entity services created in Netweaver Developer Studio and UI patterns, in this case the Object Editor pattern.

I checked the system log and throws the following line:

    Please help!!! points guaranteed!!

    Hi, I tested the application using the CAF Runtime Configuration service test and it was an authorization Issue. The entity was set to check permissions. I disabled this in NWDS and it works fine now

  • Data object editor totally empty?

    Hello,
    For some reason the Data object editor is totally empty when I try to edit an existing table or view.
    I double click on the table name -> the editor opens but without any contents. Just an empty gray space.
    This "feature" showed up a few days ago.
    What to do??
    Any help is highly appreciated.
    Owb client 10.2.0.1.31
    Owb repository 10.2.0.1.0
    Both client and repository reside on a wm virtual machine with windows server 2003 R2.
    Note! This seems to be client broblem since if I connect to the repository using OWB that is installed on my laptop, the editor seems to work fine.

    Hi all,
    And thanks for suggestions.
    I tried clicking all possible options like "Arrange all", "Fit in window" and "Auto layout". No effect.
    Finally I selected "Birds eye view" (that was deselected).
    At that moment all the sections (explorer, configuration, palette, Bird's eye view, canvas and details) showed up... very strange.
    But at the moment my problem seems to be gone.
    Thanks to all of you.

  • 11g p2 / bug - select in navigator from database offline object editor

    It is no more possible to use the context menu "Select in Navigator" from the database offline object editor (a package body in my case). I got a message "Command not handled".
    This appear in all my packages and body.
    After restarting JDev and test again I got this message "Error encountered:
    The Offline Database file is missing. Please recreate Offline Database "1" with the correct settings.
    This object in file ADMINPROCTABLE.type will be unavailable."
    Is it a way to correct this ?

    I completely reinstall JDev and set it to use subversion ... that resolve the problem and i'm no more in a position to reproduce it.

  • Can't open the Data Object Editor

    Hi everybody,
    I'm new to the OWB. Currently using the 11.2.0.1 version. Working with it is fine - but I got a major problem. I'm not able to start the Data Object Editor. I click open/new but nothing. The view doesn't change. What am I doing wrong?
    Help would be very appreciated.

    Hi everybody,
    I wanted to add some tips for newbies (like me). Yesterday I was setting up a mapping. I dropped a Joiner-Operator and weren't able to set the joiner options. If you search for a solution - in 99% the answer is Mapping Editor. But since the 11gr2 there is no editor. You just open the "Property Inspector" (under the view menu) - click on the operator (or table or ...) and there you got all the things you need. I hope this will help some of you.
    bye

    also we observed that object lock information is avaible in central lock monitor transcation but when ever there is object lcok it does not show us the the popup for object editing. 
    appreciate your valuable inputs.

    We found the problem.
    The structure was being locked by a user in the QA system and overnight the M version finally activated after another transport attempt. 
    The second structure with this problem was only referenced as a local object (even though it had a proper tech name and package assignment) preventing its activation in the QA system.  We needed to hack the query tables to make it look like a proper global structure, then re-transported and it activated.

  • View object editor for complex sql query in expert mode

    I find not convenient that the editor is modal so we cannot browse tables or procedure functions definition and that it is not possible to close it even the statement is not correct (to search for exact naming etc ...).
    May a way will be to show a list of corresponding database objects during typing like the java edit with the classes

    I filed enhancement request # 6062896 to track this suggestion. thanks.
    At a minimum, by production, we plan to re-enable the query-builder that was offered in 10.1.3, which should help with formulating queries in terms of table/column names.
