<snip> I said it's best to use same-size DS & have usage of under 30% (each DS), but it was rejected as old-recommendation. </snip>
This is/was AFAIK, the current recommendation. As to whether the "small" page ds is problem, the answer is "it depends". Perhaps the people in charge are unaware that this change(resize/drop the "small" page ds) can be performed dynamically with no observable impact to the running system. HTH, <snip> A site uses different size local page DS. say most are 200K TRK , but 1 is 10K TRK. normal : 15% 70% used problem: 60-70% 95% I said it's best to use same-size DS & have usage of under 30% (each DS), but it was rejected as old-recommendation. Sometimes they get IRA205I. MSG actually says: ... When utilization exceeds 30%, the slot allocation algorithms become less efficient, and may degrade I/O performance. Is this ROT still apply: same size local PAGE DS < 30% used </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
