Incremental statistics reduce the time to gather global statistics for a partitioned table. Really? In some situations it may happen that incremental statistics slow down statistics calculation dramatically. An example of a real project in Oracle 12.1 and how it can be improved with Oracle 12.2.
For the first time, I had the chance to attend and speak at the UKOUG Technology Conference. In these three days at UKOUG Tech17 in Birmingham, I attended some very good sessions, had many interesting discussions about Oracle databases, data warehousing and performance tuning, met nice people and tasted a lot of chocolate.
