Sets the concentrate on number of mixed garbage collections after a marking cycle to gather aged regions with at most G1MixedGCLIveThresholdPercent Reside information. The default is eight mixed rubbish collections. The target for combined collections is always to be inside of this concentrate on amount.
Boolean choices are used to possibly allow a feature that’s disabled by default or disable a function that’s enabled by default. Such possibilities don’t need a parameter. Boolean -XX solutions are enabled using the moreover signal (-XX:+OptionName) and disabled using the minus indication (-XX:-OptionName).
Don’t change off verification for the reason that this minimizes the safety provided by Java and will induce issues because of ill-formed course documents.
As there is not any encoding selection out there, the subsequent choices can be found to World-wide-web application authors:
Specifies the full quantity of Most important memory (in bytes) used for data retention. Append k or K, to specify the dimensions in KB, m or M to specify the dimensions in MB, or g or G to specify the scale in GB. By default, the scale is ready to 462848 bytes.
Once the go java command encounters a file commencing Together with the at indicator (@) , it expands the contents of that file into an argument listing just as they'd be specified about the command line.
What's more, it checks for pending exceptions amongst JNI phone calls. Any invalid knowledge encountered suggests a challenge within the native code, and the JVM terminates having an irrecoverable error in these types of situations. Be expecting a efficiency degradation when this feature is employed.
Forces stack scanning of active ways to aggressively remove unused code when only the provided proportion in the code cache is free. redirected here The default worth is ten%.
Specifies the most dimensions (in bytes) of the data chunks within a recording. Append k or K, to specify the dimensions in KB, or m or M to specify the scale in MB, or g or G to specify the dimensions in GB. By default, the maximum sizing of information chunks is about to twelve MB.
By default, this selection is disabled and also the collector is chosen quickly according to the configuration of the device and kind on the JVM. In JDK nine, the CMS garbage collector is deprecated.
The default worth is selected at run time depending on the system special info configuration. For server deployments, the options -XX:InitialHeapSize and -XX:MaxHeapSize are sometimes set to exactly the same value.
print java/lang/String toString If you’re using instructions for your JIT compiler to carry out on techniques, then begin to see the -XX:CompileCommand choice.
-XX:SharedArchiveConfigFile=shared_config_file The option is utilized to specify supplemental shared data additional on the archive file. In JDK 9, it supports strings and symbols. The string details and image details really should be created through the jcmd Instrument attaching into a running JVM procedure. See jcmd.
