Improve precision of IFCID 199 times

Currently the two measures of average I/O delay in IFCID 199 (i.e. QW0199SV and QW0199AD) are only precise to one millisecond. We are about to move some critical Production DB2 tables and indexes to SSD (Solid State Disk), which means that these two metrics will always be zero. We use the IFCID 199 data to identify I/O and bufferpool performance issues. To this end, we need a more precise measure of average and maximum I/O elapsed time.

    Thank you for submitting this enhancement request. While we view all the enhancement requests we receive as valuable and we would like to implement all of them, in an effort to have maximum transparency we are closing the ones that don’t currently appear on our two year product roadmap. This is not to say that these enhancements may not still be implemented at some point in the future as we do evaluate our requirements on the basis of customer demand and technical impact, to deliver maximum value to our customers.


    We appreciate your input to the Db2 for z/OS development team.  And we hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS. 


    Sincerely,

    The Db2 for z/OS Team
