Migration to Oracle Weblogic Server 12 c

I've been running a few web applications on Oracle Application Server 10g for a few years now.

Just got a new server with Redhat Enterprise Linux 6 to replace the old equipment. Installed Weblogic 12 c, which seemed to be the logical choice.

All I need is a simple application server J2EE with no bells and whistles, a single server and a few applications. The entire concept of servers, clusters, nodes, machines, etc. of deployments is a bit intimidating for me and possibly an overdose to the minimum infrastructure that I owe to my light apps. You will appreciate if someone shed some light in the following.

-Is Oracle Weblogic server 12 c the right product for my needs, given my small user base applications and light (JSP and Servlets)?

-What is a minimal installation? Do I really need all these - servers, clusters, nodes, machines.

-Do I need to use a NodeManager? Which is an optional component?

Thank you.

WebLogic Server in general is probably one of the most robust Java App servers out there - you receive many bells and whistles. But it's the best :)

Another point to consider is a license cost. WebLogic comes at a price. Thus, there are free solutions like Oracle Glassfish - by which is a solid java web - app server. However, I find the GlassFish somewhat complicated compared to WebLogic administration console (but that's because I'm used to WebLogic).

Which way you choose, I would like to you have not all dependencies on applications based on the products of Fusion Middleware such as ADF (frame based on Java). As the respective frame only is not supported or designed to operate on 12 c (yet).

For your WLS options, it may look intimidating, but is not bad:
-You will need an AdminServer with 1 server to a minimum.

-For machines, its all just the physical location of your WebLogic Server. It allows the node Manager to work properly. To configure, has awarded some Admin/Managed servers to whatever the machine, the servers are running on.

-Clustering is optional. However, if your applications can run in an environment cluster, then highlight cluster is a great feature to activate for high availability configurations. In your case, it might be a little too much.

-Node Manager is optional, but necessary in my opinion. It allows you to run the WebLogic administration Console controls in your WebLogic servers - such as marketing power. You can also configure Node Manager to manage the Crash Recovery - which is a very nice feature. For example, if your weblogic server goes down or is killed for some reason, Node Manager will bring the server up. Its really easy to install.

Thank you

    - Mac OS X with 32-bit JVM (1.7 GB)


    My server is Linux x 86-64. Is this 32 bit to install? or are there any Weblogic 64 bit Installer?

    Thank you

    JAI Srinivas.

    Srinivas,

    I think I got an idea after reading it several times

    This is what I understood

    checksum is a failure, so you use version 12.2 Overview disk file (1320300.1) to find which zip file must be downloaded. The overview shows V29856 - 01.zip downloaded but delivery file only has V29851 - 01 V29856 - 01.zip instead.

    I remember something like downloaded this sometimes return that I did checksum digest view used to check the integrity of files and went ahead with the buildstage.sh script to build the stadium. I have been able to complete installation without problems.

    You could try the same thing or try to rename as you suggest.

    I also recommend to contact support so that you will be clear and they will get to know.

    There is a problem:
    (1) after the creation of an Oracle WebLogic Server.

    But when I put the same file. War in Oracle weblogic server in 10.3.2.0, is to show some mistakes. Exp: resetActionlistener does not work.

    Alignments do not work as expected, it behaves in a weird way.

    I have no option to upgrade the weblogic server, and I want that my code works in 10.3.2.0.

    Please provide me with you're suggestions.

    Thank you.

    Kind regards
    K.Satish.

    I do not think the 11.1.2.1.0 ADF Runtimes are compatible with WLS 10.3.2, so why I referred you to the matrix certification and support. 11.1.2.1.0 must run on WLS 10.3.5.

    The document you sent me is for ADF 10.1.2 and is irrelevant to the discussion here. The documentation for ADF 11.1.2.1.0 can be found here: http://download.oracle.com/docs/cd/E24382_01/index.htm

  • Oracle Weblogic server and Oracle Application Server

    The Bea weblogic and Oracle application server have been combined in a product-viz Oracle Weblogic server.

    Please clarify - because Oracle Application Server is always available as a separate offering


    Thank you

    Yes, since version 10.3.4 the product called Weblogic Server provides the two "BEA WLS' and 'Oracle AS' characteristics (namely, support for forms and reports, ADF, etc..)

    Existing customers of Oracle ACEs can move to Weblogic Server to get its benefits (for example, JRockIt JVM). For the new Oracle AS it is no longer available.

  • Running Oracle Weblogic Server 11g 64 bit...?

    Hello
    How can I verify that the Oracle WebLogic 11 g server is running on 64 bit...?

    Thank you

    Hello:

    You can also do thiese orders to check the 64 bit Java:

    $JAVA_HOME/jre/bin/java - version
    $JAVA_HOME/jre/bin/java - full version

    One of these commands will show you if you are using 64 - bit.
    If you are on a 64 bit system, you must use a 64-bit Version JRE
    and the '-d64 "option with the install command.

    Soemthing like this...

    $JAVA_HOME/jre/bin/java - d64 - jar wls1035_generic.zip-log=/tmp/install.log

    Good luck!

    Here are a few suggestions

    1 make sure that you don't have any other versions of java on your machine

    2. run java-jar command directly from your JDK/bin folder, not anywhere else. You must use your JDK/bin/java command to execute the command

    Don't forget to open the command prompt in administration mode.

    Looks like you're missing a couple of jar files in the directory WEB-INF/lib directory OIA?

    Maybe aspectjrt.jar or... aspectjweaver.jar?

    If it's there, maybe permissions or ownership issues that prevents OIA to see files?
