-XX:InitialHeapSize=6m In the event you set this option to 0, then the Original sizing is about as the sum on the sizes allotted for that outdated era as well as youthful technology. The scale in the heap for the youthful generation might be set using the -XX:NewSize option.

Sets a custom command or even a number of semicolon-divided instructions to run when an OutOfMemoryError exception is 1st thrown. If the string has spaces, then it needs to be enclosed in quotation marks. For an example of a command string, see The outline from the -XX:OnError option.

Enables verbose diagnostic output in the JVM by printing a concept into the console anytime a method is compiled. This Permit’s you to check out which procedures in fact get compiled. By default, this feature is disabled and diagnostic output isn’t printed.

Specifying classpath overrides any environment in the CLASSPATH natural environment variable. If the class path option isn’t used and classpath isn’t set, then the user course route consists of the current Listing (.).

Note that PrintGCApplicationConcurrentTime and PrintGCApplicationStoppedTime are logged on exactly the same tag instead of separated in The brand new logging.

All .jar files in the specified directory, even concealed ones, are A part of the listing. A class route entry consisting of the asterisk (*) expands to a listing of each of the jar data files in The present directory. The CLASSPATH setting variable, wherever outlined, is equally expanded. Any course route wildcard expansion that occurs prior to the Java VM is started out. Java applications never ever see wildcards useful link that aren’t expanded other than by querying the atmosphere, for example by contacting Process.getenv("CLASSPATH").

Autotunes RTM locking according to the abort ratio. This ratio is specified via the -XX:RTMAbortRatio option. If the volume of aborted transactions exceeds the abort ratio, then the strategy containing the lock is deoptimized and recompiled with all locks as normal locks. This option is disabled by default. The -XX:+UseRTMLocking possibility have to be enabled.
