Cortex Configuration Files

Cortex Configuration Files

Property value changes in the Cortex configuration files are scanned and updated in the application during run time. It is not necessary to restart the server to update the values.

Creating Cortex Configuration Files

Out of the box, Cortex scans a directory for configuration files, reads the values, and updates them in the application. If the directory does not exist on your server, you can create it following these instructions.

To create the Cortex Configuration Directory:

  • Create the following directory:
    • For Windows: C:/etc/ep/cortex/system/config
    • For Linux: /etc/ep/cortex/system/config

To create a Cortex configuration file:

  • In the Cortex configuration directory, create the configuration file.

Configuration Files

Below is a list of the configuration files Cortex supports out of the box.


Defines the URI for the Cortex authentication endpoint. For more information on authentication endpoints, see Cortex Authentication

Property Format

The endpoint should be a combination of your host URI and the authentication URI, "/commerce-legacy/authentication/user".
The DEFAULT_HOST is the default fallback endpoint. Different scopes can have different endpoints. For example:


Defines the OAuth2 endpoint trust header. For more information on OAuth2 endpoint trust headers, see Cortex Authentication

Property Format"<secret trust header>""x-ep-trust-header"


Defines the authentication endpoint trust header. For more information on endpoint trust headers, see Cortex Authentication

Property Format"<secret trust header>""x-ep-trust-header"


Defines the pagination page-size setting for recommendations. Since a large number of items may be available for recommendations, this page-size setting can limit the number of items retrieved per request.

Property Format"<positive integer>"
Example with 5 items per page:"5"
Note: The 'I' is required as it indicates the value is an integer.


Defines the number of resource bundles required to register their veto before Cortex is in a ready state. During Cortex startup, resource bundles register a veto once the bundle becomes active. Before a quorum is reached, Cortex returns a 503 Service Unavailable HTTP status for any request.

Property Format

quorumSize=I"<positive integer"
Example with 10 vetoes:


Defines the authentication token's expiry time, in seconds. By default, the Cortex authentication tokens expire after 1 week (60 * 60 * 24 * 7 seconds).

Property Format

relos.token.expiry.SECONDS="token expiry seconds"

Example with 300 seconds:
