Info

For below the 2 GB bar, the SYSPLEX-wide records come in group SMF42GA1 and the MVS system records come in group SMF42G1A. Similar groups for above the 2 GB bar are SMF2AGA1 and SMF2AG1A. Example from group SMF42GA1 - SYSPLEX-wide summary In Figure 3-22 we show part of the output from running SMF42GA1. SMF42GA1 SYSPLEX D/S RESPONSE SUMMARY SET #: 0000001 YYYYDDD HH:MM:SS SMF42GAA SMF42GAB SMF42GAC 2007080 20:30:00 0000600 HSM.BCDS.RLS.DATA HSM.BCDS.RLS SMF42GAE SMF42GAF SMF42GAH SMF42GAI SMF42GAJ SC54GRT CSERLS RLS_CACHE UNKNOWN GT4KNOTACT SMF42GAP SMF42GCA SMF42GCB SMF42GCC SMF42GCD SMF42GCE SMF42GCF SMF42GCI SMF42GCL SMF42GCM SMF42GCN 0000009 0000000 0000000 0000000 0000000 0000000 0000000 0000000 0000000 0000000 . . . Figure 3-22 SMF42TG output for group SMF41GA1 A number of sets of output may be produced depending on the configuration of the SYSPLEX. The specific meanings of the fields can be found in the manual MVS System Management Facilities (SMF), SA22-7630, or can be interpreted from the IGWSMF macro in SYS1.MACLIB on the system, which may be more up to date than the version in the manual. In Figure 3-23 on page 33 we show part of the IGWSMF macro that relates to group SMF42GA1 records. In Figure 3-22: ► Fields SMF42GAA, SMF42GAB, and SMF42GAC show, respectively, the interval time, data set name, and VSAM sphere name. The SMF42GAA value can be used as an indicator that the record is valid. A value of 0 or a very high number is likely to indicate that the SMF record may be suspect. ► Fields SMF42GAE, SMF42GAF, SMF42GAH, SMF42GAI, and SMF42GAJ show, respectively, the Storage Class Name, the CACHESET name, the DFP CACHE STRUCTURE name, the indicator of the component being processed, and CF processing status indictors. The SMF42GAI field may no longer be supported. All test runs show it as a field of x’00000000’). ► The remaining fields can be interpreted from the IGWSMF macro. ► Information is provided in Appendix B, “Code samples” on page 477, where the program is described on how to alter it to process other SMF fields from those initially provided. 32 z/OS V1R8 DFSMS Technical Update
