How to refill the missing data for data points in the meta data source
I have some meta data points calculated from data points that obtain from remote site through persistent module. This central Mango was shutdown accidentally for an hour. After a day these data from the remote site were re-sync. However, the meta data were not re-filled automatically in the shutdown period. The only way I can way I know is to delete the whole set of meta data and recreate with historical regeneration. Is there any better way that I just refill the missing data in the meta data source. Thanks in advance !
I would try the following (for each meta point):
- disable the meta point
- purge all of its history
- regenerate the history
- re-enable the point
If remote updates come in while the regeneration is happening you may miss them.
Thank you of your suggestion and quick response.
