Hey, A search of the archives on this topic found some posts from back in Jan about how this option was broke in 3.7.sumthing, Bill Colwell was one of the respondees.
Anyone been brave enough to experiment with it in v4 (we're at 4.1.4)? I'm looking for ways to 'tune things up', and have been thinking about this as an option. One thing that is a bit disturbing, the Admin Guide refers you to the Admin Reference for a list of server options, yet this option is nowhere to be found in the Reference. Wonder if that is significant? On to a more academic pursuit, in looking at the tapeiobufs option there is a note telling us that this option doesn't apply to 3590 device classes at 2.10 or higher (z/OS). My guess is this is because IBM has done away with BSAM (Basic Sequential Access Method) at these levels (for what I've no clue). Can anyone verify or shed any light on this, and offer any suggestions for performance enhancement? 4.1.4.0 seems to use a lot more cycles, especially for expiration and reclamation. -- Jim Kirkman AIS - Systems UNC-Chapel Hill 966-5884
