XCF members

The number of XCF members affects the size of the sysplex couple data sets.

An XCF member is a specific function, or instance, of a multisystem application. A member resides on one system and can communicate with other members of the same group across the sysplex. The number of XCF members you specify will help to determine the size of the XCF couple data set. The number you specify should be large enough to avoid the necessity of frequent updates to increase the limit, but do not overestimate this number. If the number you specify is too large compared to current usage, performance may be degraded because of high I/O activity against the volume where the sysplex couple data set is allocated.
