Move a chart to a different database
By default the data of all charts are stored in a database
named MxChartDB, filename: MxChartDB.db.
For larger charts or charts with high-frequency writing, it may
make sense to use a separate database. You can specify a database of your
choice in the Smart Home UI app definition.
You can change this name at any time here. This will open
a new empty chart in the other database. The previously saved data
remains in the old location and is marked as 'orphaned'.
To move a complete chart with all the data saved so far to
another database, there is a special function in the 'Chart
Administration' page called 'Change Database'.
This function
- stops the running chart instance
- copies the chart tables to the target database
- corrects the chart index
- enters the new database name in the instance definition
- deletes the chart tables in the source database
- restarts the chart instance
