<p>An OOM plug-in is a gateway component, which releases RAM from a running
application or server. The function of OOM plug-in is to delegate the OOM
commands from OOM Monitor to the application. Each application provides its
own OOM plug-in, which allows OOM Monitor to communicate with that application.
The application associated with an OOM plug-in is referred as the target application
of the plug-in. </p>
<section id="GUID-61B51FD7-A314-4779-99BC-660276A409B5"><title>Priority for
OOM Plug-ins</title><p>Each OOM plug-in has a priority assigned by the OOM
Monitor in the configuration file. The priority of an OOM plug-in determines
the priority of the optional RAM allocation. For more information on setting
the priorities in the configuration file, refer to <xref href="GUID-178488C1-5453-490F-B168-9D73DB5BAE47.dita">Priority
Configuration</xref>. OOM Monitor uses the lowest priority action to release
RAM whether it is closing an application or calling a plug-in. </p><p>In the
OOM Monitor configuration file, the priority of a plug-in should
always be configured lower than the priority of its target application. Otherwise
the plug-in will never be used for releasing RAM, because the target application
is always closed before calling the plug-in.</p></section>
