13.5.5. Database Environment Variables
Database environment variables pertain to a database, if one exists, and are used to connect an application to a database. The exact variable names depend on the type of database; the value of <database> is MYSQL or POSTGRESQL as appropriate. Note that these connections are only available to an application internally; you cannot connect from an external source.
OpenShift Enterprise does not currently support user changes to environment variables. This includes changing the default MySQL admin password (even outside of phpMyAdmin). If the password is changed, ensure the change takes effect correctly. Note that this restriction only applies to the default administrative user. You can add more users as required, and specify a custom password for these users.
