Migrating from IAS 10.1.2 to 10.1.3.4

Other than the different in Application Server control GUI, if your application ear is compiled using JDK 1.42 , it might has error if it used the JDK 1.5.

Different between IAS 10.1.2 and 10.1.3

1. In 10.1.3 the dcmctl tool is no longer available, to performed the task that normally using the dcmctl you need to use the oc4j_admin at $ORACLE_HOME/j2ee/home or download the admin_client.jar in http://download.oracle.com/otn/java/oc4j/10131/oc4j_admin_client_101310.zip.

2. For the Oracle® Containers for J2EE Configuration and Administration Guide, Using the admin_client.jar Utility please refered the link here.

http://download.oracle.com/docs/cd/B31017_01/web.1013/b28950/adminclient.htm#i675530

E.g. normally to deploy application in 10.1.2 , you use

dmctl deployapplication -file xxx.ear -a TestInstance -co TestName

In 10.1.3 ,

java -jar admin_client.jar deployer:oc4j:opmn://test-cycle.oracle.com/TestName oc4jadmin welcome1 -deploy -file d:\temp\xxx.ear -deploymentName TestInstance –bindAllWebApps


3. Another important consideration in when migrating is that the default behaviour of the 10.1.3. 10.1.10 Invocation by Servlet Name without Mapping Is Disabled by Default

The 10.1.3.x Oracle Containers for J2EE Servlet Developer's Guide notes that by default, servlet invocation by class name is now disabled, but can be enabled through the property setting -Dhttp.webdir.enable=true. (Servlet invocation by class name was enabled by default in versions 10.1.2.x and prior.)

What is similar, but undocumented, is that this also applies to invoking a servlet through its value when there is no corresponding entry. Invoking a servlet through its servlet name in this way was enabled by default in 10.1.2.x and prior, but requires the setting -Dhttp.webdir.enable=true in 10.1.3.x versions.

For example, consider the following web.xml entry, with no corresponding entry:

    
 TestIt
 mypackage.TestIt

In 10.1.2.x, you could access this servlet using /servlet/TestIt without any property setting. In 10.1.3.x, you must set -Dhttp.webdir.enable=true to access the servlet in this way with the given configuration.
