Can be employed any place over the command line, like in an argument file, to forestall even further @filename enlargement. This option stops growing @argfiles just after the choice.

The objective is to own all over 2048 locations determined by the minimal Java heap dimensions. The default region dimensions is determined ergonomically dependant on the heap sizing.

Be aware that PrintGCApplicationConcurrentTime and PrintGCApplicationStoppedTime are logged on the same tag rather than divided in the new logging.

Specifies the delay between the Java application launch time and the start in the recording. Append s to specify enough time in seconds, m for minutes, h for hours, or d for days (as an example, specifying 10m implies ten minutes). By default, there’s no hold off, and this parameter is set to 0.

Sets the percentage from the heap occupancy (0 to 100) at which to start a concurrent GC cycle. It’s used by garbage collectors that cause a concurrent GC cycle according to the occupancy of your complete heap, not only among the list of generations (for instance, the G1 garbage collector).

Specifies the RTM abort ratio is specified for a share (%) of all executed RTM transactions. If quite a few aborted transactions gets to be greater than this ratio, then the compiled code is deoptimized.

Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, or g or G to point gigabytes. By default, the dimensions is set to 0, meaning that the JVM click for more info chooses the size for large web pages mechanically. See Large Webpages.

As an example, to indicate the splash.gif file from the photographs directory when commencing your software, use the following choice:

The -enableassertions (-ea) selection applies to all class loaders and to system courses (which don’t have a category loader).

This can make it very easy to permit assertions in all courses except for technique courses. The -enablesystemassertions possibility offers a independent switch to enable assertions in all method lessons.

Oracle Solaris, Linux, and OS X: The next case in point demonstrates how the -XX:OnError alternative can be employed to run the gcore command to create the Main impression, as well as debugger is began to connect to the method in case of an irrecoverable mistake (the %p designates the current approach):
