RE: Trace Evaluation

Hi,

Do you think you could decrease number of executions ?

4 blocks per fetch => probably index's blevel = 2

Is partitioning available for you? You may partition the table on acid column (I guess it's primary key).
So you get local partitioned index on acid with smaller partitions

Regards,
Ed
