Playframework 2.3.x heap size
Is there a way to set -Xmx when I start the application with "./activator"
I've tried (doesn't work):
./activator start -J-Xmx2g
./activator -mem 2048 start
_JAVA_OPTIONS="-Xmx2g" ./activator start
It says
"Raised _JAVA_OPTIONS: -Xmx2g"
but still doesn't work.
Also tried different values in build.sbt
and application.conf
- no luck
The only way I could get it to work was to use "stage" and pipe -Xmx2g
into the generated shell script, which is fine, but it doesn't separate the console.
I guess I tried everything I found on google but still no luck. I would like to somehow convey -Xmx
to activator start
.

I found a solution. There is some bug in the activator shell script, so passing the -J-Xmx argument does not remove the default options. To change the mem parameter, have a look at the activator script (/ usr / local / bin / activator) and see how to add mem parameters. Also note that passing the -v argument will print the final command to java jan. Working linux solution for me:
export JAVA_OPTS="-Xmx2700m";activator -v
# Executing command line:
java
-Dactivator.home=/usr/local/bin
-Xmx2700m
-jar
/usr/local/bin/activator-launch-1.3.2.jar
Examples of a broken solution:
_JAVA_OPTIONS="-Xmx2048m";activator -J-Xmx2700m -J-Xms1024m -v
# Executing command line:
java
-Dactivator.home=/usr/local/bin
-Xmx2700m
-Xmx2700m
-Xms1024m
-jar
/usr/local/bin/activator-launch-1.3.2.jar
Also doesn't work:
activator -J-Xmx2700m -J-Xms1024m -v
# Executing command line:
java
-Dactivator.home=/usr/local/bin
-Xmx2700m
-Xmx2700m
-Xms1024m
-jar
/usr/local/bin/activator-launch-1.3.2.jar
