Assume while performing large SPARQL update, for example of triples around 80 millions in total, one gets the following error which aborts the update:

"Transaction aborted due to a database checkpoint or database-wide
atomic operation. Please retry transaction" .

The error means that the SPARQL update has possibly encountered a database checkpoint during the load. Thus one should check the CheckpointInterval in the INI file and possible increase its value:

;
;  Server parameters
;
[Parameters]
...
CheckpointInterval       = 60
...

Note: The RDF Bulk loader can be used for loading large datasets, and it will handle the checkpoint matter automatically.
