However, setting heap parameters in > CLUSTER_PROPS was ineffective because the HornetQ run.sh would then set them > to other values later on the command line. > JBoss / Wildfly seems to do a better job of splitting the logic and > configuration, they have a script called bin/standalone.sh that contains the > logic and a separate file, bin/standalone.conf that can be customized with > environment variables. I think this would be a good model for ActiveMQ 6 to > follow. Is there already any discussion about refactoring the script? > This is important for various reasons: > - people deploying the broker in production environments don't like to modify > the scripts supplied by a vendor, they usually prefer to have a configuration > file of their own > - when upgrading, it is an extra hassle to merge changes into the scripts if > they have been modified locally > - some people may want to run multiple instances using the same installation > directory, same scripts and just using different data and log directories -- This message was sent by Atlassian JIRA (v6.3.4#6332)
