how to tune jvm when using spring boot application as unix service

Question

i'm using the new spring-boot 1.3.0 feature to run tomcat embedded spring-boot application jar as a unix service.

All is working fine but i don't know how to tune jvm (with -Xms and -Xmx parameters for example)

I've searched in spring documentation and around the web without success.

It's missing from the documentation (I've opened an issue to correct that), but you should be able to use the JAVA_OPTS environment variable.

You can configure it in a .conf file that's situated next to the jar. For example, if you jar file is /var/myapp/myapp.jar, the file /var/myapp/myapp.conf will be sourced by the launch script.

i've read that service strips all environment variables but TERM, PATH and LANG. So how can it work ? – Fabrice Deshayes Aug 27 '15 at 16:09
You can use a `.conf` file situated next to your jar. I've updated my answer with the details. – Andy Wilkinson Aug 27 '15 at 18:59
thanks for you response. it works :-) just a misspelling : "the file /var/myapp/myapp.conf will be sourced by the launch script." – Fabrice Deshayes Sep 11 '15 at 14:50

There is one more option to achieve the same , if you are running jar with mvn you can do something like this

mvn spring-boot:run -Drun.jvmArguments="-Xmx512m"

And If you are running with java -jar ,you can try something like this

java -Xmx1G -jar myapp.jar
