Logs messages tagged with a minimum of the gc and meta tags using thetrace degree towards the file metatrace.txt but turns off all messages tagged with class.
Linux only: This selection could be the equal of specifying -XX:+UseLargePages. This feature is disabled by default. This selection pre-allocates all large internet pages up-entrance, when memory is reserved; Therefore the JVM can’t dynamically expand or shrink large internet pages memory regions; see -XX:UseTransparentHugePages In order for you this conduct.
This can be a commercial feature that requires you to also specify the -XX:+UnlockCommercialFeatures solution. This really is also an experimental feature; it may well change in long term releases.
Enables flushing from the code cache in advance of shutting down the compiler. This option is enabled by default. To disable flushing with the code cache ahead of shutting down the compiler, specify -XX:-UseCodeCacheFlushing.
Together with tracking memory usage by JVM subsystems, monitor memory use by specific CallSite, personal Digital memory area and its dedicated regions.
hi/Most important The class documents that you choose to specify With this text file ought to consist of browse around this site the courses that are generally employed by the appliance. They may include any classes from the applying, extension, or bootstrap course paths.
Allows the transformation of scalar operations into superword operations. Superword can be a vectorization optimization.
Sets the utmost bytecode dimensions (in bytes) of a trivial strategy to get inlined. Append the letter k or K to point kilobytes, m or M go to point megabytes, or g or G to indicate gigabytes. By default, the utmost bytecode sizing of a trivial process is set to six bytes:
If enabled, will save jstat binary info once the Java software exits. This binary facts is saved inside a file named hsperfdata_pid, where by pid is the procedure identifier of your Java software that you choose to ran. Use thejstat command to Show the performance data contained Within this file as follows:
Enables efficiency optimization of the software with a equipment with nonuniform memory architecture (NUMA) by raising the applying's usage of lessen latency memory.
Sets the number of cache lines to load after the very last item allocation by utilizing the prefetch Directions produced in compiled code. The default price is one if the final allotted object was an occasion, and 3 if it absolutely was an array.
Sets The proportion from the heap size to make use of as the utmost for the young generation measurement. The default value is 60 % of the Java heap.
In case the JVM is run as being a assistance (for instance, as being a servlet motor for an internet server), then it can obtain CTRL_LOGOFF_EVENT but shouldn’t initiate shutdown as the running program doesn’t really terminate the process.
