&1 tasks specified for parallel scan on table &2. |
| Cause Text: |
The query optimizer has calculated the optimal number of tasks for
this query based on the query attribute degree.
The table number
refers to the relative position of this table in the query. |
| Recovery Text: |
Parallel table or index scan can improve the performance of queries.
Even though the access plan was created to use the specified number of tasks
for the parallel scan, the system may alter that number based on the availability
of the pool in which this job is running or the allocation of the table'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. |
