             Summary: Separate heap settings in standalone.conf and domain.conf from rest of JAVA_OPTS
                 Key: WFCORE-2925
                 URL: https://issues.jboss.org/browse/WFCORE-2925
             Project: WildFly Core
          Issue Type: Enhancement
          Components: Scripts
            Reporter: Brian Stansberry
            Assignee: Tomaz Cerar


Let's do this:

{code}
if [ "x$JBOSS_JAVA_SIZING" = "x" ]; then
   JBOSS_JAVA_SIZING="-Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m"
fi
if [ "x$JAVA_OPTS" = "x" ]; then
   JAVA_OPTS="$JBOSS_JAVA_SIZING -Djava.net.preferIPv4Stack=true"
   JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true"
else
   echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"
fi
{code}

That will allow users to easily control memory sizing by setting that specific env var externally while still relying on our defaults for all the other fussy stuff in JAVA_OPTS.

The JBOSS_JAVA_SIZING name was 20 secs of thought on my part.
