SYSIBMADM.QUERY_PREP_COST ADMINISTRATIVE VIEW RETURNS A VALUE LARGER THAN 100 FOR THE PREP_TIME_PERCENT COLUMN. | |

Problem description: | |
When the worst prepare time for a statement as reported by the PREP_TIME_WORST monitor element is less than a millisecond, the monitor element is incorrectly reported as 1 millisecond. This can result in the SYSIBMADM.QUERY_PREP_COST administrative view returning a percentage larger than 100 for the PREP_TIME_PERCENT column. For example if the execution time for a statement 500 microseconds (which includes the prepare time) and the prepare time was 100 microseconds, the PREP_TIME_WORST monitor element will be incorreclty reported as 1 millisecond rather than truncated to 0, and the PREP_TIME_PERCENT column in SYSIBMADM.QUERY_PREP_COST would report 200% for the statement. | |
