-- snip -- 1. Ontop for EMEA customers: I think ontop is dead in EMEA. IBM consistently refused to use ontop to look at a dump, always demanding the dump to be ftp'd in. That was (and still is) a nuisance. A colleague then wrote a program that allows us to ftp directly to IBM (don't ask me how), but without it we would still send cartridges. We have now deleted the environment. -- snip --
I prefer the ftp method to ontop. Once you set up a job to terse and send the dump to ftp.emea.inm.com it works quite well. With the old ontop method, there were constant problems with the user_id passwords and racf access. -- snip -- 2. I have just done some testing for standalone dump to a large dasd data set (and fallen flat on my face while I was at it). A word of warning: The UCB address(es) of the DASD data set are put into the preallocated DASD data set. Make sure they don't change! (This may be what the paper refers to as hiperswap, and I don't know what it is.) We mirror our DASD and when we swapped, the ucb address for each volume changed to its mirror while the former mirror became the primary. This failed sadump spectacularly! (with a message that didn't tell me anything under 1.8. I am told it changed to something meaningful with 1.9) We have now moved that data set to non-mirrored DASD. -- snip -- Hyperswap is one of the best things that have happened to reduce DASD outages. It works very well. But. Whether it was a hyperswap or a normal mirror swap, you have to be aware that the DASD device addresses have changed. GDPS takes care of this when LPARs are IPL'd (primary and secondary IPL information is primed). For SADMP, I would still aim to mirror all DASD and have separate volumes prepared for SADMP usage on the primary and SADMP usage on the secondary side. Set up separate procedures for starting it depending on whether you are running on the primary or on the secondary DASD (you always need to be aware of where your DASD currently is!). If you hardcode only a primary device number for SADMP, what do you use when your primary DASD is really hosed? -- John ---------------------------------------------------------------------- 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
