with a graphical performance detection tool. Ability to monitor memory, threads, class loading, virtual machine information, and moreVisual VM is a multi-in-one graphical performance detection tool that integrates a variety of new capability detection tools. Can replace some of the JDK's own tools, if JSTATE,JPS, etc.

First, diagnostic tools 1. Warning Log file Warning log files contain system information and error logs that contain important errors (such as: ORA-600) and block checksum error messages (ora-1578,ora-1498). Monitor database operations such as CREATE DATABASE, STARTUP, SHUTDOWN, ARCHIVE log, and RECOVER, and record Non-default initialization parameter values. When Log_checkpionts_to_alert is set to true, the warning log file also records the start and
