>We have a monoplex, a Sysplex(5 lpars) and a Sysplex(2 lpars) that share DASD.
Sorry, I misspoke a bit. When I said GRS-Ring was okay between two SYSPLEX's, I was wrong. It's between images. Since the GRS token has to be passed to each image to ensure global ENQ's, the more the worse the response. GRS* only works within a single SYSPLEX. MIMgr works because (as long as the CDS is not in a CF), every system talks directly with the master system (oldest IPL), so there is only passing of data between the requester and the master -- no passing around a ring. The ring is the bottleneck, and you have eight systems -- way to many! If you can afford the fees, I'd stick with MIMgr in your config. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
