Hi All,
WebObjects 5.3
Mac OSX 10.5.8
Openbase 11.0
we are having a performance issue when we delete a record.
application functionality is
delete record
create log record in another table
the delete works fine when there is less than 168763 records in the
table we are deleting from, but as soon as there is 168764 the
delete takes 6 MINUTES,
the editing context contains 1 deleted object, 1 inserted object and
2 updated objects, which are the same in both the transactions.
the time lag occurs during the editingContext.saveChanges() method
we use the openbase plugin to generate the primary keys and the
openbase simulation file shows the same sql is being executed and
the primary keys are being referenced.
Can anyone offer a direction on where to look?
You have verified that the exact same SQL statements are issued each
time? Based on that slim evidence, I'd suspect the database. Deletes
should only be a problem in EOF if you are triggering off a lot of
delete rules (cascading) or firing off the faults for a large inverse
relationship.
