Additional considerations

The following additional considerations apply to the +RUNSTATS parameter:

BMC AMI Load updates column statistics for every column of every index.
You can also have BMC AMI Load collect frequency distributed statistics can also be collected. The BMC AMI Stats parameters (from the STTPARMS DD) control frequency statistics collection. If the STTPARMS DD does not supply these parameters for the load job, BMC AMI Load obtains them from the BMC AMI Utilities configuration.
For partitioned table spaces, BMC AMI Load does not update table statistics unless there is an index on the partitioning columns or a DPSI defined.
For a list of which Db2 catalog statistics you can update, see Overview of BMC AMI Stats.
