The COUPLE=xx system parameter specifies the COUPLExx parmlib member used when you IPL your system. See Planning the COUPLExx member in parmlib for planning information for this member.

If you do not specify the COUPLE=xx parameter, COUPLE=00, which specifies the COUPLE00 parmlib member, is used. The IBM-supplied default COUPLE00 parmlib member causes the system to come up in single system sysplex mode without couple data sets, (which is also called XCF-local mode).

LOCAL is the sysplex name in the IBM-supplied default COUPLE00 parmlib member. The name LOCAL has no special meaning to XCF. In XCF-local mode, the installation can specify any sysplex name. Note, however, that the IPL will fail when using the IBM-supplied COUPLE00 parmlib member if a sysplex name other than LOCAL is specified in LOADxx.
