To bypass the file system type check, set the -XX:+PerfBypassFileSystemCheck option on the java command line for both the
|
|
applications you want to monitor and for the jvmstat tools. Setting this option for target applications is application
|
|
specific. For the jvmstat tools, the following environment variable can be set before running any of the commands:
|
|
set VMARGS=-XX:+PerfBypassFileSystemCheck
|
|
|
|
_JAVA_LAUNCHER_DEBUG
|
|
|
|
|
|
javac options:
|
|
javac -Xpring classname
|
|
|
|
memory
|
|
-XX:CompressedClassSpaceSize=160m
|
|
by default is 1GB.
|
|
-XX:MaxRAMPercentage"
|
|
for java 10, but we still need to know this percentage
|
|
-XX:UseCGroupMemoryLimitForHeap
|
|
It'll tell JVM to calculate how much memory it could use for heap based on memory available to Docker container,
|
|
so you don't need to guess heap size.
