<concept id="GUID-8AB46129-0B35-539D-ACC8-2816A4EE2FC9" xml:lang="en"><title>Configuring
the Start-up State Aware (SSA) Behaviour</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>This page describes how to configure how ECom behaves during system boot.
It is intended for Symbian Developers optimising or troubleshooting the boot
process for a phone. </p>
<p>The Symbian platform has a Staged Start-up Architecture, driven
by the Application Framework's System Starter component, which provides a
consistent and customisable method of starting components at device boot.
The architecture divides the start-up process into a number of <i>states</i>,
which allows components to perform only those start-up actions which are necessary
to the state. This allows the start-up sequence to be optimised, so that functionality
that is immediately important to the user starts first. Components that use
this architecture to manage their start-up are called Start-up State Aware
(SSA). </p>
<p>By default, ECom is SSA. It loads registration files for plug-ins on read-only
internal drives first, while start-up is in the "Critical" state. Registration
files for plug-ins on other drives (i.e. installed third-party plug-ins) are
loaded later, when start-up moves to the "Non-critical" state. </p>
<p>ECom's SSA behaviour can be disabled, in which case all plug-in registration
files on all drives are loaded when ECom is started. To disable the SSA behaviour,
place a file called <filepath>EComSrvr.ini</filepath> in either of the directories <filepath>C:\private\10009D8F</filepath> or <filepath>Z:\private\10009D8F</filepath>. The file can have any contents or be empty: its existence alone disables
the SSA behaviour. To reenable SSA, remove <filepath>EComSrvr.ini</filepath> from
both directories. </p>
