Ideally, the value of this measure should be low. If this measure shows high value, then by making use of detailed diagnosis you can find the name of the wait event, the total number of waits, the total time waited, and the average wait time per event. With the help of such data you can identify those objects with a high wait time; such objects naturally are resource-intensive. To reduce the resource drain induced by the object, you need to make sure that accesses to the object are low on wait time. This can be ensured by employing the following techniques:
- adding indexes to right column;
- rebuilding the indexes;
- reorganizing the table;
- By fine-tuning thequery which accesses the object.
