A common example of a process VM is the Java Virtual Machine (JVM), which enables Java applications to run on any device with a JVM installed. Process VMs are particularly useful for application portability and ensuring that software behaves the same way across different platforms. How Virtual ...
After the bytecode successfully loads, the Java interpreter creates an instance of the JVM that allows the Java program to be run natively on the underlying machine. What does JRE consist of? Besides the Java virtual machine, JRE is composed of various other supporting software tools and feature...

exceed threshold for maximum JVM memory consumption; shutdown OC4J instance. Passivation of beans is performed using the least recently used algorithm: of the beans eligible for passivation, OC4J passivates the least used first. In addition, you can specify how frequently OC4J checks this criterion...
Theory of operation gProfiler invokesperfin system wide mode, collecting profiling data for all running processes. Alongsideperf, gProfiler invokes runtime-specific profilers for processes based on these environments: Java runtimes (version 7+) based on the HotSpot JVM, including the Oracle JDK and...
A statement may be consist of a very simple expression, like a single literal; or a complex expression with assignment and or comma operators. Most statements have statement key words, like "var", "if", "while", "break", etc. Multiple statements may be grouped together to form a stat...
The CRaC (Coordinated Restore at Checkpoint) project from OpenJDK can help improve these issues by creating a checkpoint with an application's peak performance and restoring an instance of the JVM to that point. To take full advantage of this feature, BellSoft provides containers that are highly...

A session bean is the most generic type of enterprise bean, representing a chunk of business functionality that can be called by a client. The client in this case could be another class in the local JVM or a remote call. The EJB container manages the session bean lifecycle, which is deter...
T3 is an optimized protocol used to transport data between WebLogic Server and other Java programs, including clients and other WebLogic Servers. WebLogic Server keeps track of every Java Virtual Machine (JVM) with which it connects, and creates a single T3 connection to carry all traffic for a...
