• The ORO_ENTERPRISE_LICENCE value defines the project enterprise licence.

• The ORO_JPEGOPTIM_BINARY path to the LiipImagineBundle: JpegOptimPostProcessor library.

• The ORO_OAUTH_PRIVATE_KEY_PATH path to the OAuth private key.

Default Configuration Values

Default configuration options for the Oro application are defined in the config/config.yml file. Some options have inline values, and others refer to environment variables, therefore they can be set and changed in runtime without application cache rebuild. Default values for environment variables are provided at the end of the config/config.yml files, with the parameter names in the format env(ENVIRONMENT_VARIABLE_NAME).

Sample Configuration Parameters

The sample contents of the <installation directory>/config/parameters.yml file for OroCommerce:

parameters:
    # Enable GridFS support
    gaufrette_adapter.public: 'gridfs:%env(ORO_MONGODB_DSN_PUBLIC)%'
    gaufrette_adapter.private: 'gridfs:%env(ORO_MONGODB_DSN_PRIVATE)%'

    # Enable Redis support
    redis_dsn_cache: '%env(ORO_REDIS_CACHE_DSN)%'
    redis_dsn_doctrine: '%env(ORO_REDIS_DOCTRINE_DSN)%'
    redis_dsn_layout: '%env(ORO_REDIS_LAYOUT_DSN)%'

Environment Variables

An environment variable is a variable with a value outside the application, typically through a functionality built into the operating system. You can find the list of all the infrastructure-related environment variables available in the application in the config/config.yml file.

In the above parameters.yml file example, the web_backend_prefix parameter value is provided directly in the YAML file and cannot be changed in runtime without the application cache rebuild, while the database_dsn environment variable can be set in runtime by the environment variable named ORO_DB_DSN.

The default value for the ORO_DB_DSN environment variable is provided at the end of the file and is set to postgresql://root@127.0.0.1/b2b_crm_ee_dev. It is used when the environment variable ORO_DB_DSN is not provided.

Warning

Environment variables are always string and are not cast automatically to integer, null, or other types. You should never pass an empty environment variable, like ‘ORO_DB_DSN=’ or ‘ORO_DB_DSN=NULL’. Instead, it should never be available (never be set).
