Migrating application from 9.0.4.1 to 10.1.3

Hi All
I hope this is the correct forum to ask this question. We are migrating a J2EE application which consists of several CMP beans from OC4J 9.0.4.1 to OC4J 10.1.3.
On initial observation it seems that 10.1.3 also generates a config file similar to 9.0.4.1 called 'toplink-ejb-jar.xml'. In 9.0.4.1 we manually edited the pre-generated 'orion-ejb-jar.xml' file to add all our JNDI names and CMR relationships.
Looks like Oracle has bundled TopLink with this version of OC4J - I assume we need to end up doing the same thing for this pre-generated file ?
Does anyone have experience doing this ? If so can you share some tips ?
Thanks in Advance
Ghulam

Ghulam,
The toplink-ejb-jar.xml file is typically created from mapping your entities to the tables in the mapping editor provided in JDeveloper or the standalone workbench utility. It is not a direct 1:1 association with the orion file.
We have provided a migration utility for moving from the orion CMP to the new default CMP (TopLink).

  • Does anyone have experience with migrating applications from iAS6.0 SP2 to SP3? Did it go smoothly or are there problems to be expected?

     

    Hi,
    I haven't. But, there are lots of changes from each service packs,
    henceforth you may have to stick to what the documentation says to avoid
    the errors that shoots up. Again, the errors depends upon how you have
    coded your application. Please let me know if you have encountered any
    errors and the messages for me to help you.

  • Migrating application from tomcat 3 to tomcat 5

    Hello everybody,
    Does anyone have information about some kind of manual or tutorial with steps to migrate applications from Tomcat 3 to Tomcat 5??
    Thanks a lot,
    Johnny

    What issues are you having? There have been some important changes between the Servlet and JSP specs between the two but most of these have been additions - nothing that will be too hard to handle.
    Does your application use a database? If so there have been configuration changes between Tomcat 3 and 5 but for that the Tomcat 5 docs are very good at telling you what you need.
    I would start by trying it and see where you get problems. I think it will be easier than you think, depending on how complicated your app is.

  • Mail no longer works after migrating applications from Mountain Lion

    This weekend I bought a Mac Pro 2.1. I upgraded it to Lion then migrated all my files and applications from my iMac (running Mountain Lion). Now the Mail app doesn't work. I can't uninstall it and Software update says everything is up to date. How can I get my Mail app to work again? I guess I've somehow copied the Mail app from the Mountain Lion mac which is why it won't run.

    No unfortunately after the OS  is installed the installer package is removed so you'll need to go through the whole procedure again.
    There is a way to save the installer and make a bootable flash drive you can install off of. You should be able to find the procedure if you search here or on the net.

  • Link/checklist for migrating applications from Oracle 9i to Oracle 11g?Help

    Hi all,
    We need to perform an impact analysis on migratiing an application from Oracle 9i to Oracle 11g. Does any of you have a detailed checklist to follow, in terms of queries, PL/SQL statements, optimizer etc. etc., when attempting this migration. We require something more specific from the application point of view rather than a DBA point of view.
    Additionally, we have queries written extensively with rule hints. Should there be a special consideration for the same since now we are moving to CBO in 11g
    Even if any one has a link, that would help. Thank you so much!

    Hi Nikhil,
    Thanks Xaheer,You're welcome :)
    I'm going through the link: http://download.oracle.com/docs/cd/E11882_01/server.112/e10819/toc.htm
    But it still mentions stuff from a DBA angle. I need from an application angle.
    Do I need to change my queries taht are current written with RBO? Do I need to change Pl/SQL blocks ?Please refer tech below notes:

    Do you have the problem with all JSP pages, or only a few of them ?
    Does it happen in the Embedded OC4J only ?
    Could you try to deploy your application in the Standalone OC4J and test it from there ?
    I had a similar issue where the Embedded OC4J was unnable to run big JSP pages.
    There was no problem with the Standalone OC4J.
    Hope this helps,

  • Migrating Application from JSP 1.2 to JSP 2.2 and Servets 2.3 to Servlet 3

    Hi,
    I have an application which is built on JDeveloper 10.1.3.4.
    So it uses default JSP and Servlet Runtime i e, JSP 1.2 and Servlets 2.3 versions.
    But i want to migrate my application from those versions to Servlet 3.0 and JSP 2.2.
    So i downloaded JSP 2.2 API jar and Servlet 3.0 jars and added to my Application Library.
    I even removed JSP runtime and Servlet run time.
    Now am unable to compile.
    How should i migrate my application from older versions to newer.
    Thanks,

    a) you learn to use your tools properly
    b) you fix what you did wrong
    c) you feel smug for having done your job

  • Migrating Application from Planning 11.1.2.1 to 11.1.2.2

    Gurus
    I am trying to migrate a Planning application from Hyperion version 11.1.2.1 to version 11.1.2.2. Is there a way that I can use LCM? I have tried exporting the application from version 11.1.2.1 and importing it in 11.1.2.2 but all the forms are being registered as invalid.
    The application also use business rules and LCM gave the following errors:
    Error in migrating artifact, "/Global Artifacts/Business Rules/Global Variables/XXXXX".
    Cannot process artifact (XXXXXX). Unsupported artifact type (Global Variable).
    Since Calc Manager is the only supported tool would this cause the problem with the migration process? If so, how do I migrate the application successfully.
    I saw the upgrade option in the Planning Administration but how is application in the situation.
    Thanks in advance.

    Hi John
    Thank you for this I used the back-end migration and the steps are as follows for those that will need the help:
    1. Create a shell Planning app in 11.1.2.2
    2. Backup the database for the application created above
    3. Synchronize HSS between the source and destination environments (luckily I didn't have to do this)
    4. Take a copy of the database for the source application
    5. Stop the Hyperion Planning service (I stopped all the Hyperion Services to be safe)
    6. Restore the database of the source application on top of the database for the destination application.
    7. Confirm that owner SID for the app is still the same in the destination
    8. Clear the version of the application in the planning database
    9. Start Hyperion services in the destination application.
    10. log into planning and it will ask you to upgrade the application.
    11. Once thats done remember your substitution variables (in Planning), location aliases and the data (exported & imported as text files through EAS).
    Thanks John for the help.

  • How do I migrate applications from old MacBook Pro to a MacBook Air?

    How do I migrate applications such as Word & iWork from my old Macbook Pro running Lion to my new MacbOok Air, running Mountain Lion?
    Thanks for advice. Cheers.

    One way: if you have a backup of your MBP on an external disk which you could connect to your MBA, or you could establish a connection in between the two Macs, you may want to launch the "Migration Assistant" on the MBA. You'll find it in Applications under Utilities. It guides you through the steps and options.
    The other (better) way is re-installing all apps fresh, and best the latest versions and updates to make sure it's all ML compatible. "Purchases" in the App Store are helpful as you simply download and install the latest and greatest again. For MS Word etc you should have the install disks. It's a bit more work but usually worth it.

    You should be calling wrap() to wrap your keys, not doFinal(), or alternatively initializing your cipher to be ENCRYPT'ing, not WRAP'ing.

  • Migrating Application FROM Visual Basic

    Hi Everyone,
    I have an application written in Visual Basic (Front End) and SQL Server as the Back End. Now this application should run on the web i.e need to web enable the application.I have coded in Java for sometime now,but I do not have any prior knowledge as to build a Web application from scratch.Can anyone let me know
    how to procced.I would like to use open source like JDK for development.Eclipse for IDE.
    Thanks,
    Supriya.

    First off let's get VB specific -- Are you using Access as a local database and container for your queries? If you are then read on, otherwise, the information already give is excellent and complete enough to get you well on your way.
    1 - You are going to have to conver all of your queries either to SQL and store them in a business layer, or create stored procedures for them on the server. I strongly recomend the stored procedure route to hide any detail of your dataserver as much as possible and supply tighter security for table access.
    2 - Your web server is going to be a significant ralleying point for your data and return HTML generation, you should take that into consideration with your IT staff and how it will affect other applications on that server. (It will probably not have sufficient impact, unless you already have your own dedicated server for this application)
    3 - As mentioned by the others, the Applet/Servlet or JSP/Servlet configuation will serve you very well for your application.

  • Migrating Application from JDev 10.1.3.5 to JDev 11.1.2.2.; WebLogic issues

    Hi,
    I've been in the process of migrating an application we have from JDev 10.1.3.5. to the most current release. This involved migrating from OC4J to the WebLogic Server. After clearing up code-related issues, I have been trying to mitigate errors that came from deploying the application to the WebLogic server. I fixed (or so I think) the original error(see immediately below in italics) by deleting the servlet tag in both of the web.xml files (ViewController and Deploy) that are within the application. I also changed it to 'adfLibResources' per a previous thread on this topic.

    I think your web.xml that is a part of the application had the following:
    <taglib>
    <taglib-uri>
    http://xmlns.oracle.com/adf/faces
    </taglib-uri>
    <taglib-location>
    /WEB-INF/lib/adf-faces-impl.jar
    </taglib-location>
    </taglib>
    I think this is not even your configuration but something that JDev added, thus you can consider testing removing this part of the code and test your application and verify the functionality.
    Regarding the possible issue during migration from 10g to 11g of Jdev, you can review the following thread:
    Class not found : oracle.adfinternal.view.faces.taglib.UIXPanelTag
    The missing class is a part of "adf-faces-impl-1013.jar" which seems to be specific to the JDev 10g, thus might not be even required by JDev11g.
    Also regarding the fact that how this seems to be an issue with missing class, please review the following API doc for better understanding of the classnotfoundexception:
    http://docs.oracle.com/javase/6/docs/api/java/lang/ClassNotFoundException.html

  • Migrating Application from weblogic 8.1 to weblogic 10.0 - Urgent

    Migration
    Edited by: user2647658 on Jan 5, 2009 8:49 PM

    Mukul,
    Thanks - I may appear as though I know what I'm doing, but I'm at a similar stage to you - I have to upgrade to 10.3 early next year and have so far only moved a single JVM for development use and checked my application works.
    What I learnt was that 8.1 - 10.* is a huge step, various JMS/JDBC configuration options you were used to in 8.1 have now been simplified - for example, the JDBC DataSource and Connection pool you had in 8.1 has now been replaced by a single entity.
    I'm pleased that the JDBC connection works - where does that SQL statement come from, as it looks like there's something not quite right about that.
    Now that you have that working, make a backup of the folder and try to deploy one of your applications. First off, try to do this through the WebLogic console and see what errors, if any you get. Do you have jar files on the system classpath at all in WLS8.1? If you do, you may want to stick them in the lib folder of the domain just to get it working - I don't think that's the recommended approach, but it will do as a test to see if it works.
    Upgrade Approach_
    As for the approach to upgrade, I have the same issue (although only 6 - 8 developers to worry about) Within WLS 10.* there is a scripting language called WLST, and my aim is to create a base domain for development and once that's ready all the developers will delete the existing 8.1 domain and run the wlst script to create the new one, deploy all the applications and all will work nicely. That's just what I'm aiming for and I'm a long way off at the moment.
    So, it will be an automated upgrade, but will be a brand new domain structure - 8.1 and 10 I think are so different, its difficult to make the change seamless - but WLST will help ( I hope )
    How I upgrade my production environment with clusters etc I have no idea at the moment
    let us know how you get on
    Pete
