Additional Upgrade Procedures and Information

WebLogic Server Clusters on Solaris

Certain applications (heavy EJB apps) deployed in a WebLogic Server cluster on Solaris will perform better using the client JVM rather than the server JVM. This is especially true under heavy loads.

Web Services

Due to changes in the Web service runtime system and architecture between versions

6.1and 7.0 of WebLogic Server, you must upgrade Web services created in version

6.1to run on version 7.0.

The WebLogic Web services client API included in WebLogic Server 6.1 of has been deprecated and you cannot use it to invoke 7.0 Web services. WebLogic Server 7.0 includes a new client API, based on the Java API for XML-based RPC (JAX-RPC).

For detailed information on upgrading a 6.1 WebLogic Web service to 7.0, see Upgrading 6.1 WebLogic Web Services to 7.0 at http://e-docs.bea.com/wls/docs70/webServices/migrate.html.

For examples of using JAX-RPC to invoke WebLogic Web services, see Invoking Web Services at http://e-docs.bea.com/wls/docs70/webServices/client.html.

For general information on the differences between 6.1 and 7.0 Web services, see Overview of WebLogic Web Services at http://e-docs.bea.com/wls/docs70/webServices/overview.html.

Writable config.xml File

WebLogic Server 7.0 automatically updates configuration information read from the 6.x config.xml file to include WebLogic Server 7.0 information. In order for these changes to be retained between invocations of the server, the config.xml file must be writable. To allow the file to be writable, make a backup copy of your config.xml file from your 6.x configuration and change the file attributes.
