Oracle DatabaseIt is widely used in various fields of society, especially in the Client/Server mode. However, application developers often encounter the problem that the performance of the entire system decreases significantly as the data volume increases. To solve this problem, in the following aspects: the database server

In some cases, a thread dump is automatically created for the Java™virtual Machine (JVM), such as a situation in which WebSphere application Server stops in a way other than ordinary stopserver requests. Thread dumps can also be triggered by signaling to the WebSphere
Introduction
Application logging provides a way to capture the various events that occur during application execution. It collects detailed information about what the application is doing when it performs various tasks. This information is useful for debugging, troubleshooting, and even auditing.
