Cache Subsystem Overview Report

The purpose of this report is to show key characteristics (cache hit rates and cache miss rates) for the cache subsystems of interest in your installation.

The template consists of a variable part which must be repeated for each control unit included in the Overview Record, and a fixed part, which is necessary for the spreadsheet macro to determine the last control unit included in the report.

                          -------------- Variable Part, replace cu with
                          -------------- the address of the control unit
OVW(RHTcu(CASRHT(SSID(cu))))         Total Read hits rate
OVW(WHTcu(CASWHT(SSID(cu))))         Total Write hits rate
OVW(MRNcu(CASMRN(SSID(cu))))         Normal Read miss rate
OVW(MRScu(CASMRS(SSID(cu))))         Sequential Read miss rate
OVW(MRCcu(CASMRC(SSID(cu))))         CWF Read miss rate
OVW(MWNcu(CASMWN(SSID(cu))))         Normal Write miss rate
OVW(MWScu(CASMWS(SSID(cu))))         Sequential Write miss rate
OVW(MWCcu(CASMWC(SSID(cu))))         CWF Write miss rate
OVW(DFBcu(CASDFWB(SSID(cu))))        DFW bypass rate
OVW(CFBcu(CASCFWB(SSID(cu))))        CFW bypass rate
OVW(DFIcu(CASDFWI(SSID(cu))))        DFW inhibit rate
OVW(NCIcu(CASNCICL(SSID(cu))))       Non-cache I/O ICL rate
OVW(NCBcu(CASNCB(SSID(cu))))         Non-cache I/O bypass rate
OVW(ASYcu(CASASYNC(SSID(cu))))       Async rate
                          ------------------------
OVW(LASTRNG(CASRHT(SSID(cu))))       should be added at the end

You can either use the macro Create Overview Control Statements to generate control statements for any cache control unit in your installation, or you can use the function Create Exceptions which is part of the macro Cache Subsystem Report, pointing to your most important control units (Excel only).

If you want to monitor two control units 0050 and 0068, you can create the following overview control statements:

Example:

OVW(RHT0050(CASRHT(SSID(0050))))
OVW(WHT0050(CASWHT(SSID(0050))))
OVW(MRN0050(CASMRN(SSID(0050))))
OVW(MRS0050(CASMRS(SSID(0050))))
OVW(MRC0050(CASMRC(SSID(0050))))
OVW(MWN0050(CASMWN(SSID(0050))))
OVW(MWS0050(CASMWS(SSID(0050))))
OVW(MWC0050(CASMWC(SSID(0050))))
OVW(DFB0050(CASDFWB(SSID(0050))))
OVW(CFB0050(CASCFWB(SSID(0050))))
OVW(DFI0050(CASDFWI(SSID(0050))))
OVW(NCI0050(CASNCICL(SSID(0050))))
OVW(NCB0050(CASNCB(SSID(0050))))
OVW(ASY0050(CASASYNC(SSID(0050))))
OVW(RHT0068(CASRHT(SSID(0068))))
OVW(WHT0068(CASWHT(SSID(0068))))
OVW(MRN0068(CASMRN(SSID(0068))))
OVW(MRS0068(CASMRS(SSID(0068))))
OVW(MRC0068(CASMRC(SSID(0068))))
OVW(MWN0068(CASMWN(SSID(0068))))
OVW(MWS0068(CASMWS(SSID(0068))))
OVW(MWC0068(CASMWC(SSID(0068))))
OVW(DFB0068(CASDFWB(SSID(0068))))
OVW(CFB0068(CASCFWB(SSID(0068))))
OVW(DFI0068(CASDFWI(SSID(0068))))
OVW(NCI0068(CASNCICL(SSID(0068))))
OVW(NCB0068(CASNCB(SSID(0068))))
OVW(ASY0068(CASASYNC(SSID(0068))))
OVW(LASTRNG(CASRHT(SSID(0068))))

The macro Cache Subsystem Overview Report processes converted Overview Records which have been created based on this control set.
