Parallel Container Creation

DB2 Version 7.2 allows you to create table space containers in parallel. This enhancement helps to improve the performance of I/O operations if you are using database-managed space (DMS) device containers for your table spaces.

Starting with Version 7.2, you can create or resize several DMS containers in parallel, with the degree of parallelism equal to the number of available prefetchers plus one. For example, if you have 10 prefetchers, you could resize 11 containers at the same time.

Note:
Prefetchers retrieve data from disks and move the data into the database buffer pools before applications need the data.

For more information on creating or resizing containers in parallel, see the DB2 Release Notes. For more information on managing device containers, see the Administration Guide: Performance.
