SQL4025 - Parallel table preload access method used

SQL4025
Message Text:	Parallel table preload access method used
Cause Text:	The query optimizer chose to use a parallel table preload access method to reduce the processing time required for this query. This means that the data accessed by this query will be loaded into active memory when the query is opened.
Recovery Text:	Parallel table preload can improve the performance of queries. Even though the access plan was created to use parallel preload, the system will actually use parallel preload only if the following are true: The query attribute degree must have been specified with an option of IO or ANY for the application process. There is enough main storage available to load all of the data in the file into active memory. Normally, 5 megabytes would be a minimum. Increasing the size of the shared pool may improve performance. For more information about parallel table preload, refer to Data access on DB2 UDB for iSeries: data access paths and methods.
