We aren't a school, so You can't enroll in a very course, but people today are welcome to utilize the products without spending a dime as research aids.
Autotunes RTM locking based on the abort ratio. This ratio is specified through the -XX:RTMAbortRatio possibility. If the number of aborted transactions exceeds the abort ratio, then the method made up of the lock is deoptimized and recompiled with all locks as standard locks. This option is disabled by default. The -XX:+UseRTMLocking selection should be enabled.

Enables the dumping in the Java heap to the file in The existing Listing by using the heap profiler (HPROF) when a java.lang.OutOfMemoryError exception is thrown.
Handles large log documents. The number may be in the form of numberM or numberK. The default is about to 512K.
