Updating COUPLExx to define the z/OS UNIX CDS to XCF

Update the active COUPLExx parmlib member to define a primary and alternate z/OS® UNIX couple data sets to XCF. Place the primary and alternate couple data sets on separate volumes. (The sample JCL in Creating a couple data set (CDS) shows the primary CDS on volume 3390x1 and the secondary CDS on 3390x2.)

Figure 1 shows the COUPLExx parmlib member; statements that define the CDS are in bold.

The MVS™ operator commands (DISPLAY XCF, SETXCF, DUMP, CONFIG, and VARY) enable the operator to manage the z/OS UNIX CDS.
