Archiving

Faster and more flexible archiving​.

• A local PostgreSQL® database installation can now be done automatically. This is also the recommended backend type to be used. It will be set as new default during project creation. This will save valuable configuration time. Of course, any other archiving option (including RDB Oracle®) can still be used for new projects as well.
• No additional WinCC OA license costs if backend and database are running on the same WinCC OA server (1 local instance, independent from the database type).
• Disaster Recovery System for maximized system availability is supported for NGA PostgreSQL® as well (previously only available for RDB Oracle®archiving).
• Improved read performance for PostgreSQL® backend through optimized indexing.
• AMS/APM Solution packages will be available for PostgreSQL® with a later update for 3.20.

Importer for switching projects to the Next Generation Archiver

• The NGA Importer provides the possibility to convert the complete configuration of an existing RAIMA/Value Archive (HDB) project to SQLite®/NGA.
• Import existing historical data into NGA projects.
• All historical values and alarms can be imported.
• Import data even during normal operation due to automatic importer speed threshold.
• Newest values are imported first.
• Note: SQLite® for last value and data model storage is only available in combination with NGA.
• Switching to NGA – as future-proven archiving option - was never easier.
• No extra costs, as operation does not have to be stopped and importing can run automatically in the background.
