Additional supporting features – PB Docs 2021

A system function IsPowerServerApp is added
to check if the current application is an installable cloud
application deployed using PowerServer.

The SystemError event is enhanced to return errors that
are specific to the installable cloud application or PowerServer
license.

The Application object has
added the following new functions in order to support OAuth 2.0
authorization server for installable cloud apps:

An option “Begin session by code” is added to the
Application painter’s Properties view.

This option is not selected by default; which means the
session is automatically created when the application starts. If
this option is selected, then the session will not be
automatically created; it will be created only when the BeginSession function is
executed. Normally you may want to create a session using BeginSession after you
have obtained the access token, so that the session can include
the access token.

An option “During compilation, report unsupported
PowerScript features for PowerServer deployment” is added to the
Application painter’s Properties view.

If this option is selected, the PowerScript features that
are unsupported by the PowerServer Web APIs will be detected and
reported during the deployment process.

The Application object provides a function (GetSessionID) for getting
the session ID of the current application client.

The PowerServer C# solution provides interfaces (LoadAll
& KillByID) for getting all user sessions and killing the
specified session. For more details, see Get/Kill
user sessions.

The DBParm CacheName property is
enhanced to specify the database connection cache used by the
installable cloud app.

The DBParm CacheGroup property is
added for specifying the cache group to be used by the
installable cloud app.

The DBParm ProcedureInTransaction
property is added for specifying whether to start the
transaction when executing a stored procedure for the
installable cloud app.

PowerServer 2021 supports the following database
parameters: CacheGroup, CacheName, DelimitIdentifier,
DisableBind (static DW retrieve), TrimSpaces, TimeStamp
(Oracle), BindSPInput (Oracle, SQLServer), and
ProcedureInTransaction.
