Home -> Community -> Mailing Lists -> Oracle-L -> RE: Last Update
If you have just set a table as "monitoring" (and have no other tables already set for this option), then you may not actually see any rows in this table for a while. The one downfall with this option (if you want/need real time info) is that this table may not update for some time after the table/data has been modified.
Go back to it in an hour or so..
