Point is that you are not meeting your SLA goals. If DASD response time is an issue, then it can be described as 'poor DASD performance'. It does not really matter what the response times are, the issue is that they are too slow.
In this context a ROT for any delay would be zero, IMHO. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Lizette Koehler Sent: Wednesday, July 21, 2010 11:39 AM To: IBM-MAIN@bama.ua.edu Subject: Any ROT for DASD Response time We are running an EMC DMX4500 shared with the open system side. MVS has 9TB and the open side has 500TB. So they win. We have points in time where our production application (DB2 Stored Procedures with Native SQL) has slow responses. The DBAs are using RMF and TMON (DB2 and MVS) to isolate the problem. However, they see DFHSM and say thats the problem. I think I am seeing delays on the dasd the DB2 system uses in RMF. But I am not sure how to interpret the numbers. Is there a ROT that says if the delay rate is > ? then the dasd is poor performaing?
