This option exploits
the available containers when it loads data and significantly improves
load performance.
The maximum number that
is allowed is the greater of four times the BL_CPU_PARALLELISM value,
which the load utility actually uses, or 50. By default, BL_DISK_PARALLELISM
is equal to the sum of the table-space containers on all table spaces
that contain objects for the table that is being loaded except where
this value exceeds the maximum number that is allowed.
If you do not specify
a value, the utility selects an intelligent default that is based
on the number of table-space containers and the characteristics of
the table.
For more information
about using this option, see the DISK_PARALLELISM parameter in IBM
DB2 Universal Database Data Movement Utilities Guide and Reference.
