WinPlatform object runtime behavior

  • Last UpdatedJul 19, 2024

Runtime behavior pertains to the running state of a deployed WinPlatform object. Once deployed and operating, WinPlatform objects can assume one of several states:

State Change

Behavior

Startup

During this transition state, AppEngine objects hosted by the WinPlatform object and with a startup type of Semiautomatic or Automatic are started when the WinPlatform starts up.

Going onscan

During this transition state, for data that have calculated quality, the quality property is updated. When going onscan, data quality is set to INITIALIZING. Data quality is subsequently set to GOOD during execution.

Running onscan

In this state, all statistics are calculated.

Going offscan

During this transition state, for data that have calculated quality, the quality property is updated. When going offscan, data quality is set to BAD.

Offscan

In this state the WinPlatform object and all hosted objects are passive.

Shutdown

During this transition state, AppEngine objects hosted by the WinPlatform object are shut down upon shutdown of the WinPlatform object.

Important! Since the WinPlatform must be onscan for any of its hosted objects to be onscan, it is important that the Windows computer to which the WinPlatform is deployed to always be running in order for the system to function properly.
