JVM配置参数中文说明

用java -X 命令查看JVM的配置说明：

-----------------------------------------------------------------------

D:\j2sdk15\bin>java -X

    -Xmixed           mixed mode execution (default)

    -Xint             interpreted mode execution only

    -Xbootclasspath:<directories and zip/jar files separated by ;>

                      set search path for bootstrap classes and resources

    -Xbootclasspath/a:<directories and zip/jar files separated by ;>

                      append to end of bootstrap class path

    -Xbootclasspath/p:<directories and zip/jar files separated by ;>

                      prepend in front of bootstrap class path

    -Xnoclassgc       disable class garbage collection

    -Xincgc           enable incremental garbage collection

    -Xloggc:<file>    log GC status to a file with time stamps

    -Xbatch           disable background compilation

    -Xms<size>        set initial Java heap size

    -Xmx<size>        set maximum Java heap size

    -Xss<size>        set java thread stack size

    -Xprof            output cpu profiling data

    -Xfuture          enable strictest checks, anticipating future default

    -Xrs              reduce use of OS signals by Java/VM (see documentation)

    -Xcheck:jni       perform additional checks for JNI functions

    -Xshare:off       do not attempt to use shared class data

    -Xshare:auto      use shared class data if possible (default)

    -Xshare:on        require using shared class data, otherwise fail.

 

The -X options are non-standard and subject to change without notice.
