Sysplex Infrastructure: The Care and Feeding of Couple Datasets

Project and Program: MVS, MVS Core Technologies

Tags: Proceedings, SHARE in Boston 2013, 2013

This session provides a comprehensive overview and detailed discussion of couple data sets (CDS).  The speaker will cover basics such as: What is a CDS? Why do I need one? How is it used? How do I create one? How do I get the sysplex to use it? He will discuss in detail the sysplex couple data set,  the various function couple data sets, and explain terminology such as "primary CDS", "alternate CDS", "PSWITCH", "active policy", "administrative policy", "format utility", and "policy utility". There will also be a discussion of best practices and "real world" mistakes seen by the XCF level 2 service team with an eye towards helping you avoid them in your shop (and how to recover if possible). Those that are new to sysplex should walk away with a firm grasp of all that is needed to confidently deal with couple data sets in their sysplex.  Those with experience will find value as well -- even if most of the basics are well known -- as they should walk away with a more detailed understanding that should enable them to better ensure that couple data sets in their sysplex are configured and managed in a way that avoids unnecessary risk.  After all, mistakes with a CDS can lead to a sysplex wide outage!
