Coupling facility level
The CFCC code is released as Levels, usually denoted by their CFLEVEL. For example, CFLEVEL 15 was announced in April 2007. Each level brings new function and sometimes improved performance. In most cases the new function or performance improvement requires a corequisite release of z/OS and perhaps new function in some subsystem (such as Db2). One such example is Coupling Facility Structure Duplexing. (Sometimes support from the operating syste… WebCoupling Facility Activity Report Field descriptions of the summary sections of the Coupling Facility Activity Report The following table describes each field on the summary sections of the Coupling Facility Activity Report. 1 This field is applicable only for coupling facility level 15 and higher.
