NextGen Archiver (NGA) Importer - Basic Panel

The basic panel already contains ideal default values and the use of the panel is recommended for most use cases.

  • Open the Importer panel via System Management > Database > NGA Importer and then open the Basic Panel.
    Figure 1. NGA Importer - Basic Panel

You can import data by using the buttons of the Controlling section - see below. The estimated remaining time of the import is shown at the bottom of the panel.

Note: If the importer migrates from one backend (e.g. InfluxDB®) to another (e.g. PostgreSQL®), only as many licences must be available as there are writing backends. The read source backends are not counted.
Note: Make sure that enough licenses are available for the project (not in the demo mode), otherwise inconsistencies may occur (the project restarts after 30 minutes).

Importers

Figure 2. Importers
  • The importer is activated with the check box Automatic import on project start in the panel NGA Migration. With the activation, a list of importers for the previous configuration is created and the import is automatically started. There is one importer for each Value Archive and one for the alert history from RAIMA DB. The internal data points for the Value Archives still have to exist for this purpose (they are not deleted by project upgrade). The Import timespan from the Expert panel - Configuration is applied here. Also the conversion of the archive configs from Value Archive to NGA has to be performed before (see chapter Conversion Settings).
    Note: Note that the configuration data of the value archives (names, segment duration, retention) will also be taken over to the configuration of the newly created NGA groups.
    Note: When importing historical alarms/values from a RAIMA/HDB database into an NGA project, the languages used in the RAIMA/HDB database must be identical to the languages used in the NGA project.
  • Completion shows how much data was imported.

Controlling

Figure 3. Resume all / Pause All
Figure 4. Start all / Pause All
  • Start all - Start the data import of all importers.
  • Pause all - Interrupt the data import of all importers with the option to resume the data import. If you resume the import later, it will resume from the point where it was paused.
  • Resume all - resumes the import from the point where it was paused - see above.
