Use the DISPLAY XCF command to display cross system coupling information in the sysplex. … Requests that the system display (message IXC356I) detailed signalling path information for one or more named coupling facility structures. You may specify ALL to request information for all coupling facility structures. Wildcard (*) suffixes are allowed.
9/10/2020 · IBM Mainframes: the enterprise computing platform that led to the evolution of the modern “Cloud Computing Technology” – Nov 11, 2020 An overview of the Parallel Sysplex and Coupling Facility on the IBM Z Mainframes – Sep 10, 2020; Understanding how a ‘CM0 SL1 – ACK’ Input Message sent to IMS Connect works – Jun 30, 2020, z / OS and CA Top Secret use the definitions in the Coupling Facility Resource Management (CFRM) policy when managing the coupling facility storage.The CFRM policy resides in a CFRM couple data set which the system programmer creates using the IBM IXCL1DSU format utility program.
IBM Z Coupling Facility Encryption … • Stage 1 in the z / OS v2.3 timeframe provides display -only capabilities for sysplex resources such as z / OS systems, coupling facilities, coupling facility .
z / OS sysplex, cross-system coupling facility (XCF), Coupling Facility Resource Manager (CFRM), SFM, system Logger) and other components like BCPii, z / OS Resource Measurement Facility (RMF) and z / OS Job Entry Subsystem 2 (JES2), JES3, SDSF, z / OS Interactive System Productivity Facility (ISPF), time-sharing, Important: Your z / OS systems teams must allow enough white space in each coupling facility to allocate all of the structures in both coupling facilities. In the rare event that a coupling facility fails, for whatever reason, the structures should rebuild quickly in the remaining coupling facility .

Ways to monitor group buffer pools You can monitor group buffer pool activity by using a z/OS or Db2 command, by using a coupling facility activity report, or by using a statistics trace. Group buffer pool monitoring with the z/OS DISPLAY XCF,STR command You can monitor group buffer pools with the DISPLAY XCF,STR command.
Use the DISPLAY system command to display information about the operating system, the jobs and application programs that are running, the processor, devices that are online and offline, central storage, workload management service policy status, and the time of day.
