The AIX platform provides a /etc/environment that allows global environmental variables to be exported for all users of a given machine. UEM Server adds the environment variables defined in this file to the user's login environment.
 
The order in which it is processed by UEM Server is slightly different than the order used by the AIX login process. The AIX login process reads and processes the following files in the order listed:

<ol>
<li> <b>/etc/profile</b>
<li> <b>/etc/environment</b>
<li> <b>$HOME/.profile</b>
<li> <b>$HOME/.env</b>
</ol>
<br>
The LOGIN option directs a UEM Server to use the login shell to execute the event handler process. The AIX login shell does not process the <b>/etc/environment</b> file, so UEM Server processes the files in the following order:
<ol>
<li> <b>/etc/environment</b>
<li> <b>/etc/profile</b>
<li> <b>$HOME/.profile</b>
<li> <b>$HOME/.env</b>
</ol>

If the environment is established, the SHELL used to execute an event handler process is invoked as a login shell, which reads and executes commands from the system and user profiles. The profiles that are read and executed depends on the type of shell invoked.

If the environment is established, the user's environment block is loaded and the user's registry hive is mapped to HKEY_CURRENT_USER. This makes the user's profile available to the handler process.
