This selection was deprecated in JDK eight with no alternative, following the deprecation of your -XX:+CMSIncrementalMode possibility. The option was eradicated in JDK 9, since the entire incremental mode was eliminated.
-XX:SharedArchiveConfigFile=shared_config_file The option is accustomed to specify additional shared information extra on the archive file. In JDK nine, it supports strings and symbols. The string data and image data really should be created from the jcmd Device attaching to the managing JVM approach. See jcmd.
When present at operate time, --illegal-obtain= takes a keyword parameter to specify a manner of Procedure:
By default, this selection is disabled and also the collector is selected quickly based upon the configuration from the machine and sort from the JVM.
Sets the most code size (in bytes) for compiled techniques that ought to be inlined. Append the letter k or K to indicate kilobytes, m or M to point megabytes, or g or G to point gigabytes.
By default, this feature is disabled and no optimization for NUMA is created. The choice is available only once the parallel garbage collector is used (-XX:+UseParallelGC).
Sets the Java thread stack size (in kilobytes). Utilization of a scaling suffix, for instance k, brings about the scaling from the kilobytes benefit to ensure that -XX:ThreadStackSize=1k sets the Java thread stack dimensions to 1024*1024 bytes or one megabyte. The default worth is dependent upon the platform:
When the JVM is run for a service (for example, for a servlet engine for an online server), then it can obtain CTRL_LOGOFF_EVENT but shouldn’t initiate shutdown since the running technique doesn’t in fact terminate the method.
Sets the worth in the end-the-earth (STW) employee threads. This selection sets the worth of threads to the amount of reasonable processors. The worth of threads is look at this now the same as the volume of sensible processors nearly a value of 8.
It ought to be utilized only on equipment with many sockets, the place it improves the efficiency of Java programs that rely check my reference on concurrent functions. Only the Java HotSpot Server VM supports this selection.
Differing kinds of data can’t be blended. Multiple divided facts sections for the same form specified by unique @SECTION are allowed inside one shared_config_file .
Set The share of your time (0 to 100) accustomed to increase conservatism when computing the obligation cycle. This selection was deprecated in JDK 8 with no substitution, subsequent the deprecation with the -XX:+CMSIncrementalMode choice. The choice was eradicated, since the overall incremental mode was eradicated.
Logs messages tagged with the gc tag using the trace level into a rotating file set with 5 documents with dimensions one MB with The bottom identify gctrace.txt and uses decorations uptimemillis and pid.
Method will exit. The flag -XX:+PrintFlagsRanges prints the variety of all the flags. This flag find more info permits automated screening of your flags by the values supplied by the ranges. With the flags that have the ranges specified, the type, title, and the particular variety is printed within the output.
