LISTENERXML
Specifies the full path to the listener.xml file.
Syntax
LISTENERXML = <path to file>
Usage and Examples
listener.xml is a Lycia configuration file where custom application server instances can be defined and configured. LISTENERXML specifies the path to this file, if any.
LISTENERXML takes one parameter – a path to the folder.
Suggested locations for your custom configuration files are
But you can choose any other folder for your custom configuration files, if necessary.
Regardless of what folder you choose to store your listener.xml, you must specify the path to this folder as a value of LISTENERXML and set it in your system environment.
To set LISTENERXML in your system environment, you must follow these steps:
On Windows
Step 5. In the opened window, enter the variable name – LISTENERXML – and its value.
You can specify more than one folder to store your custom configuration files.
The folders must be separated with ; on 
Windows and : on 
Linux.
The same procedure is used to change the value and to delete LISTENERXML from your system environment.
On Linux
Step 0. Open the system configuration file in your favorite text editor..
$ vi /etc/environment
Step 1. Set the value for LISTENERXML.
export LISTENERXML=/home/my_configs/lycia
Step 2. Save the changes and close the system configuration file.
Step 3. Log out of the system and then log in back with your user to apply your changes.
Step 4. Check whether your changes to the system environment were successfully applied.
echo $LISTENERXML
/home/my_configs/lycia
If you have other custom configuration files besides listener.xml, you must set the path to their location in LYCIA_CONFIG_PATH.
If you want to store all your custom configuration files in one folder (including listener.xml), you can set only LYCIA_CONFIG_PATH and do not set LISTENERXML.
If you want to store listener.xml separately from your other custom configuration files, you must set both LISTENERXML and LYCIA_CONFIG_PATH.
