What is Java_opts environment variable?

JAVA_OPTS is an environment variable that you can set to pass custom settings to the Java Virtual Machine (JVM) that runs Liquibase.

if your JAVA_OPTS is set in Windows then with simple:

echo %JAVA_OPTS%

in linux

echo "$JAVA_OPTS"

but it is possible that it is set first in your standalone.bat file. Then its valid only for execution time of standalone.bat (.sh) file and you can find its value in this file.
