This APAR concerns customers who partition table spaces based on a timestamp column. When this customer moved to DB2 10 this query lost the ability to prune partitions on a partitioned table space and the response time increased dramatically. In this case the application was comparing the timestamp column to a host variable with a timestamp precision (6). The temporary fix is to use PLANMGMT to fall back to the previous access path.
· PM81692 – performance degradation for table partitioned on timestamp
This APAR deals with table insert experiencing longer than expected space search times. This can occur when the clustering index does not provide an adequate position for insert within the table.
