Why bother? If the volume is dedicated to JES2 spool (i.e. only one dataset), then I'd make the VTOC(0,1,14) with no index at all. That leaves the rest of the volume for the dataset. You could even go to VTOC(0,1,1). There is no need for an index at all. An index is only useful if you have a large number of VTOC I/Os going on. On this volume, once JES2 has OPEN'ed the HASPACE dataset, the VTOC should not be hit again until the next JES2 restart. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
