The file aliases.conf is renamed to databases.conf. An old aliases.conf from a previous version can simply be renamed and the new engine will just continue to use it as before. However, databases.conf can now include some configuration information for individual databases.

Scope of Parameters

Some parameters are marked as configurable per-database or per-connection.

Per-database configuration is done in databases.conf.
Per-connection configuration is primarily for client tool use and is done using the DPB parameter isc_dpb_config or, for Services, the SPB parameter isc_spb_config.
In the case of Embedded, the DPB can be used to tune per-database entries on first attaching to a database.
