Abstract

OSP-OTHER-PERFM OPNQRYF INTERMITTENTLY PERFORMS POORLY

Error Description

OPNQRYF intermittently performs poorly.                        
                                                               
Applications that perform repeated and limited positioning by  
key during the single open of the cursor may intermittently use
more CPU when the file is mostly resident in memory.            
The query tends to perform better when the file is not resident
in memory.                                                      

Problem Summary

Please see the ERROR DESCRIPTION section.                      

Problem Conclusion

Changes were made to improve the performance of data space      
paging performed during native key positioning.
