SQL4033 - &1 tasks specified for parallel bitmap create using &2

SQL4033
Message Text: &1 tasks specified for parallel bitmap create using &2
Cause Text: The query optimizer has calculated the optimal number of tasks to use to create the bitmap based on the query attribute degree.
Recovery Text: Using parallel index scan to create the bitmap can improve the performance of queries. Even though the access plan was created to use the specified number of tasks, the system may alter that number based on the availability of the pool in which this job is running or the allocation of the file's data across the disk units.

Refer to Data access on DB2 UDB for iSeries: data access paths and methods for more information about parallel scan.
