Java Performance Tuning with Mission Control and Flight Recorder

Course:  MCJFR
Duration:  4 Days
Level:  II
Course Summary

This course teaches experienced Java programmers how Java garbage collection works and how it affects your applications. You'll develop the knowledge to select the appropriate garbage collector and performance goal for your applications. The Student will know how to use Mission Control and Java Flight Recorder tools to monitor and analyze your applications.. The Student will build a conceptual background for Java garbage collection. The instructor will teach you how it it applies to Java garbage collectors on the Hotspot JVM.
