Oracle JVM Rolling Patching

2.14 Oracle JVM Rolling Patching

Oracle JVM Patching is the process of patching the Oracle executable and the corresponding Java classes that make up the Oracle JVM, where both must be in sync to run Java in the database.

Oracle JVM uses rolling patching, which enables one instance to continue running the current version of the JVM classes with the current executable and customer Java classes, while the other instances (both the Oracle executable and the JVM classes) are being patched. Once patched, an instance with the new executable and JVM classes are able to immediately run customer Java code as soon as it is started.
