Possibly the EC12's Flash memory, which come in huge chunks of relatively cheap memory, can help speed up the process of having dozens TBs of temporary datasets in memory.
Kees. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Martin Packer Sent: Wednesday, April 23, 2014 13:42 To: [email protected] Subject: Re: SORT ando MEMLIMIT best practice I don't disagree: I didn't really talk implementation but I want to see very large temp data sets in memory, controlled via DFSMS and not too expensive. First step is "very large" IMHO but recast to be cheaper in CPU terms at the same time would be welcome.
