Locking is one of the most important aspects in Java application programming. When applications are multi-threaded, they must protect data from concurrent updates. Locking protects the integrity of shared data in a multi-threaded application. There are some conflicts that locking can cause if used improperly. Some of these problems are deadlocks, improper or frequent lock acquires and excessive locking... [More]
Java is one of the most well-known and used programming languages today, which makes Java Virtual Machines (JVMs) integral in today’s application programming. When working with a JVM, you will undoubtedly encounter performance issues at some point. When these problems arise, the thread data provided by the IBM Tivoli OMEGAMON XE on z/OS Monitoring Feature for JVM can be invaluable in resolving the issue. JVMs split work across multiple threads... [More]
