Create DB connection profiles – PB Docs 2022

In the Database page >
Advanced tab, you can create various
DB connection profiles which include database connections to be used
in different environments, for example, database connections for the
development environment, testing environment, production environment,
etc.

Each DB connection profile will have a corresponding Applications.[DBConnectionProfile].json created
in the compiled Web APIs > AppConfig folder (or the solution >
UserExtensions project > AppConfig folder) for storing its settings such
as database connection cache(s), transaction-to-cache mapping(s) etc.
For example, the default Applications.json stores the settings of the
“Default” connection profile, Applications.Test.json stores the settings of
the “Test” connection profile, Applications.Production.json stores the
settings of the “Production” connection profile.

You can then decide which connection profile to be used in the
application by selecting the profile and clicking the Set as Current button. The name of the current
profile will be stored to the “POWERSERVER_ENVIRONMENTTYPE” setting in
the compiled Web APIs > AppConfig
folder > AppConfig.json
file.
