Okay, I’ve logged a ticket for this particular issue… There is an alternative strategy that you could use for this, though with this technique not using the official “internal historian”, it won’t be a candidate for sync’ing the history data over the gateway network (one of the original uses for the internal historian is for Ignition Edge where some local history capture can occur but using EAM Data Sync, it can sync the data to an upstream Gateway Tag Historian). Here are some steps you can consider (though the particulars will likely vary somewhat for your installation):
- Create a new SQLite Database Connection–the path specified (if not explicit) will be relative to your Ignition installation, so you could choose something like
- Observe the new History datasource that should show under Config->Tags->History.
- Migrating tags over to using this history datasource instead of the official “Internal Historian” will allow you to place that internal history database file in a path of your choosing (in step 1).
Granted, the steps above don’t accommodate moving over any of the accumulated history you have already. Additionally, with this technique using a different database structure than the internal history DB, it isn’t as simple as just copying the current
HistoricalData.idb into place as your new database.
From the looks of it, this should be a relatively easy fix, I’ll try to keep this forum post updated with any progress on our ticket for this.
Hope this helps,
