Using Startup Extensions
Startup Extensions can be found in the MA_HOME/bin/ext-available folder. This directory contains scripts that act as extensions to the generic MA scripts. Extension scripts can be enabled by copying an extension file to the MA_HOME/bin/ext-enabled dir to the scripts in this directory. This allow extensions to persist even after a upgrade of the Mango core.
Extensions are run in the source shell, and so can define or override variables defined in other scripts. Extensions are provided a parameter in their call that determines the current activity. These are init, start, restart, and stop.
Setting Mango / Java Memory on startup
The most common extension use are the memory extensions to override the system defined memory given to Mango.
