| Oracle9i Application Server Migrating from Oracle Internet Application Server 1.0.1 Release 1.0.2 for Windows NT Part Number A87391-01 |
|
This chapter explains the process of migrating from Oracle8i JVM version 8.1.6.1 to 8.1.7 in Oracle9i Application Server.
The migration topics for this component are:
You should not need to modify the configuration files that are installed as part of Oracle9i Application Server 1.0.2. However, if you modified the 1.0.1 configuration files to better support Java in some way, such as expanding shared_pool_size, then you should re-examine what you modified and why, and consider whether similar modifications would be appropriate in 1.0.2.
No environment migration tasks are necessary.
If you modified the Oracle Internet Application Server 1.0.1 configuration files, then you should examine what you modified and consider whether similar modifications would be appropriate in 1.0.2.
Oracle9i Application Server 1.0.2 includes new features to support servlets and JavaServer Pages. If you used servlets or JavaServer Pages in Oracle Internet Application Server 1.0.1 through Apache JServ, then you can deploy them to run on Oracle8i JVM.
In addition, this release supports version 1.1 of the Enterprise JavaBeans (EJBs) specification. If you used EJB 1.0 features in Oracle Internet Application Server 1.0.1, then you now have the option in Oracle9i Application Server 1.0.2 to use the new EJB 1.1 features, such as Entity Beans. However, no automated migration tools are available to redeploy servlets, JSPs, EJBs, or CORBA components on Oracle8i JVM in Oracle9i Application Server 1.0.2. You must manually redeploy this Java code to Oracle9i Application Server 1.0.2.
The tools for Java application deployment, which includes stored procedures, EJBs, CORBA, servlets, and JSPs, are documented in Oracle8i Java Tools Reference in the Oracle9i Application Server Documentation Library. Use these tools to redeploy any existing Oracle Internet Application Server 1.0.1 Java code to Oracle9i Application Server 1.0.2 as needed.
No changes have been made to the existing tools. However, ncomp has been added. JServer Accelerator, implemented within the ncomp tool, natively compiles all classes within the specified JAR, ZIP, or list of classes, and places them into shared libraries according to their package. Note that these classes must first be loaded into the database.
