VM agents are a good way to assess what is happening inside the Java Virtual Machine (JVM). Learn what VM agents are, what they can do, and how they work.
More Java memory-related command line arguments You can find more options for controlling Java application memory use by looking at the output of the java -X command. Here's what the output of those commands looks like from my JVM: $ java -X -Xmixed mixed mode execution (default) -Xint...
A JVM argument can be added using this format: wrapper.java.additional.6=-Dorg.mule.xml.validate=false Setting properties on the command line when starting Mule The startup script for Mule allows you to enter ad-hoc JVM arguments via the -M flag (see MULE-2601). The format is: mule...
Enabling the project-setting "coverage_extra_args" for JVM based projects would be fairly easy and would allow to pass additional settings to the jacoco-agent commandline parameters and thus allow to configure jacoco with additional settings. However this would not fully solve my use-case of limi...
If needed, provide any JVM arguments via the JAVA_OPTS variable in that script. Make sure that script does not write anything to standard output other than calculation results. (Optional) OpenJDK 21 is used by default. If a custom JDK build is required, create a copy of prepare_baseline....
As dependencies for my Java 8 app, which produces a *.jar which can be run by both JRE 8 or JRE 9 with no additional arguments. In addition, this needs to be executed somewhere before JAXB API will be used: System.setProperty("javax.xml.bind.JAXBContextFactory", ...
To determine this manually, I have to run a ps -aef | grep <name-of-app> for each app I want to check. For example, to see if myapp.jar is running as a process, I run ps -aef | grep myapp, and look for a grep result that describes the JVM process representing myapp.jar. Th...
Update from 32-bit to 64-bit Java TeamCity server is bundled with the 64-bit JVM but can run under both 32- and 64-bit versions. If you need to update 32-bit Java to 64-bit JVM, note that the memory usage is almost doubled when switching from 32- to 64-bit. Make sure to...
To apply this modifier to the JVM used by Mule, you can set a parameter in /conf/wrapper.conf which automatically triggers the creation of a heap dump during: wrapper.java.additional.<n>=-XX:+HeapDumpOnOutOfMemoryError wrapper.java.additional.<n>=-XX:HeapDumpPath=path/to/dumps/dump....
The value you pass as an argument to a method can be a literal value (2, ‘c’, etc.) or a variable of the declared parameter type (for example, x where x is an int variable). (There are other things you can pass as arguments, but we’re not there yet.) A method must declar...
