Recompile Java user-defined routines
After you revert and before you start the earlier server, recompile Java™ user-defined routines (UDRs) that were compiled with a Java development kit version that is earlier than or equal to the version included with the previous server.
What you do depends on whether your application uses external JAR
and class files or JAR files installed on the server:
- If your application uses external JAR and class files (for example, JAR and class files that are listed in JVPCLASSPATH), recompile the files.
- If your application uses JAR files installed in the server (for example, through the install_jar() support function), you must remove the old JAR file (by using the remove_jar() support function) and reinstall the recompiled JAR file in the database.
