This chapter includes the following information to install and configure Oracle TopLink on your computer:
The Oracle Universal Installer includes TopLink with the basic Oracle Application Server install. To install only TopLink, select the Advanced installation type, then choose Oracle TopLink. This will install the TopLink Foundation Library and TopLink Workbench.
Use the following procedures to install TopLink (including TopLink Foundation Library and TopLink Workbench). Before you install TopLink, back up all existing project data.
|
Warning: If you are upgrading from a pre-Release 1 (9.0.3), you must convert the package names before you open your TopLink project(s) in 10g Release 3 (10.1.3). Refer to "Package Rename" for more information after installing TopLink. |
This section includes information on:
Use this procedure to start the Oracle Universal Installer and install TopLink 10g Release 3 (10.1.3).
For Windows operating systems:
Ensure that you are logged in to the computer as a member of the Windows Administrators group.
When configuring TopLink for use with J2EE containers, you must modify the System Variables—not the User Variables.
For Unix or other non-Windows operating systems:
Insert the TopLink installation disk into the CD-ROM drive to launch Oracle Universal Installer, or download the installer from:
http://www.oracle.com/technology/products/ias/toplink/index.html
For Windows operating systems:
If your computer supports the auto run feature, the installer will automatically launch on your computer.
If your computer does not support the auto run feature, execute the G:\setup.exe program (where G is the letter for your CD-ROM drive) to start the installer.
For UNIX or other non-Windows operating systems:
If your computer supports the auto run feature, the installer will automatically launch on your computer.
If your computer does not support the auto run feature, enter: prompt> mount_point/as_1013disk/runInstaller to launch the installer.
|
Caution: Do not start the installation inside themount_point directory. If you do, then you may not be able to eject the installation disk. |
Complete each screen of the installer.
When the installation is complete, you must configure the TopLink Workbench environment.
For more information, see "Configuring the TopLink Workbench Environment" in the Oracle TopLink Developer's Guide.
Refer to <ORACLE_HOME>\toplink\doc\index.htm for the latest Oracle TopLink Release Notes.
Silent installation mode is available for all installation types. You can use the silent installation when you wish to make multiple installations simultaneously or when you perform installations from a remote location. Silent installation eliminates the need to monitor the installation because there is no graphical output and no input by the user.
Insert the TopLink installation disk into the CD-ROM drive.
Open the \Stage\Response directory and select the oracle.as.j2ee.top.toplink.rsp file.
Copy the oracle.as.j2ee.top.toplink.rsp file to a temporary (tmp) location.
Edit the following parameters in the oracle.as.j2ee.top.toplink.rsp file:
Start the installer.
For Windows operating systems, open a command prompt window and enter:
setup.exe -responseFile c:/oracle.as.j2ee.top.toplink.rsp -silent
For UNIX and other non-Windows operating systems, open a command prompt window and enter:
./runInstaller -responseFile /tmp/oracle.as.j2ee.top.toplink.rsp -silent
If your installation was successful, the silentInstall.log file contains the line:
"The installation of TopLink was successful."
At runtime, the TopLink Foundation Library requires the Java Runtime Environment 1.3 (or higher). By default, the TopLink installation includes the JRE 1.5.
To configure TopLink for a different version of the JRE, change the <ORACLE_HOME>/toplink/bin/setenv file to point JAVA_HOME to the alternate directory.
After installing TopLink Workbench, you must configure the following:
TopLink Workbench requires the Java Runtime Environment 1.4.2_06 (or higher). By default, the TopLink installation includes the JRE 1.5.
To configure TopLink for a different version of the JRE, change the <ORACLE_HOME>/toplink/bin/setenv file to point JAVA_HOME to the alternate directory.
Java Cryptography Extension (JCE)
The TopLink Workbench uses JCE to encrypt database login information. JCE is included with JDK 1.4 (or higher).
By default, TopLink installs only a portion of TopLink Workbench online help system on your PC. To access the complete documentation from Oracle, ensure that your PC is connected to the internet and the your proxy information (if necessary) is correct.
For more information on how to specify the help mode, see the Oracle TopLink Developer's Guide.
From the TopLink Workbench menu, select Tools > Preferences. On the Preferences dialog, select General to configure your proxy information.
Depending on the TopLink Workbench project, you are required to update the DRIVER_CLASSPATH environment variable to add the location of the following (if necessary):
J2EE Connector Architecture (J2C) adapters – If you are using TopLink Workbench Enterprise Information System (EIS) projects.
Oracle Database <ORACLE_HOME>/rdbms/jlib/xdb.jar file – If you are using direct to XML type mappings with an Oracle9i or higher database.
Custom Collection class that you use to override the default Collection class that TopLink uses with a mapping container policy.
For more information on how to update the DRIVER_CLASSPATH environment variable, see "Configuring the TopLink Workbench Environment" section in the Using TopLink Workbench chapter in the Oracle TopLink Developer's Guide.
If you plan to use additional, third-party libraries (such as XMLType Mappings or EIS with Attunity), when deploying your Oracle TopLink project, you must copy the appropriate JAR file to <ORACLE_HOME>/toplink/jlib. Additionally, you must include the libraries on you server's classpath.
To start TopLink Workbench, simply execute the workbench.cmd or .sh file in the <INSTALL_DIR>/toplink/bin directory. The TopLink Welcome Screen appears.
If you receive a "Cannot Find Main Class" error, ensure that you have configured JAVA_HOME correctly. See "JRE Version".

Note: On Microsoft Windows XP platforms with mapped network drives, the TopLink Workbench File Chooser dialogs (such as Save File or Open File) may experience slow responses for opening and traversing directory trees. Unmapping the network drives eliminates this behavior. |
TopLink provides a tutorial with which you can create an Employment Management System for your company to be deployed in a three-tier environment using JSP servlets. The tutorial shows you how to store data from a Java class into a relational database and access existing database information from Java classes.
Specifically, you will learn how to:
Create a new TopLink Workbench project
Enable and add Java classes
Create and import database tables
Associate descriptors to tables
Implement direct and relationship mappings (including self-relationships)
Use indirection and value holders
Apply several advanced features such as multiple tables and optimistic locking
Write TopLink queries
Create and manage database sessions
Package and deploy a TopLink application
For more information about the tutorial, see the Oracle TopLink Developer's Guide. See also the TopLink Tutorial at:

After you install TopLink, if you encounter problems either starting the application or connecting to a database, try the following solutions:
Ensure that the driver class name is correct. Many vendors have several different driver classes to choose from.
Check your login information.
Ensure that your path includes all .dll files your driver requires.
Check with your database administrator that:
Any drivers that require special set-up in the database server (such as Sybase JConnect) have been set up correctly.
Any drivers that require special permissions in the database server have been set up correctly.
You are not exceeding the number of available concurrent connections to your database. This may occur during development time, when many people are testing connections.
If you use database servers that requires an extra Windows NT service to be running for JDBC connections, ensure that one is running.
Check with your vendor to ensure that you are using the latest version of both your JDBC driver and the database to which it is connecting.
If it takes an extremely long time to start TopLink Workbench after the splash screen appears (for example, more than 30 seconds), ensure that your proxy help mode and proxy information is correct. See "Online Help and Documentation" for details.
