I've used it for years. IIRC it was originally called VIOPlus from Softworks. No real issues with it although there are a few cases where a job will gag on it but it is easy to bypass. It is basically dynamic buffering for VSAM and Sequential datasets. Nothing you can't do through JCL yourself if you have the (lots of) time to put into it. I think it's worth it and it does dramatically improve I/O performance.

Does anyone have experience with it? Basically does it significantly improve I/O and is it trouble free? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
