We used a DataMiner backup (.dmbackup file) to restore a system.
This system includes some elements that generates some DVEs and we notice that, after the restore, the DVEs were using a new element ids. A different situation from the parent/regular elements, where DataMiner kept the same element id.
Is this expected?
We were using DataMiner 10.1.2.
Hi Bruno,
DVEs are exported from a table that resides in the main element. That table has a column with option ‘element’ which will contain the ElementID that gets assigned to the exported DVE when it is initially created.
DataMiner will load this table on startup and maintain the same element ID, as they are saved into the table.
Could you check if the database was also restored?
If so, I would expect the same element IDs to be used. If not, DataMiner will generate new rows and new element IDs.
Hi Bruno, just to make this point more visible:
- DVE information is stored in the database, so to retain your DVE configuration, you must save and restore full backups with the database included.
In Cassandra, the table responsible for DVE information is dveelementinfo. You can find your DVE element IDs there:
Hey Leander,
That’s correct. Probably something went wrong during that particular restore job.
