CACHE
The CACHE control statement causes the CMF MONITOR Extractor to collect configuration and activity data for all or selected cache subsystems.
[SUBSYS=(nnnn1,nnnn2,nnnn3,....nnnn16)]
[EXCLUDE=(nnnn1,nnnn2,nnnn3,....nnnn16)]
[RECORDS={(}CACHE,ESSLINK,ESSRANK,ESS,ALL{)}
Monitoring modes | Only one CACHE statement can be defined for each monitoring mode, continuous (CPM) or intermittent (IPM). If more than one CACHE statement is specified, only the first statement will be accepted. All other statements are discarded. Specifying multiple CACHE statements does not adversely impact initialization of the PAS. | |
Sampler and record types | The CACHE statement controls the Cache/ESS sampler, which produces SMF type 74-5 and 74-8 records. As of version 5.6.00 of CMF MONITOR, SMF 240-27 records are no longer produced. | |
Analyzer statements and reports | CACHEACT (for reports based on SMF type 74-5 records) ESS (for reports based on SMF type 74-8 records) | Cache Subsystem Overview Report Cache Subsystem Activity Report (when REPORT=SUBSYS is specified) Cache Device Activity Report (when REPORT=DEVICE is specified) ESS Statistics Report |
Other BMC Software products | The CACHE control statement must be defined in the Extractor JCL for MainView for z/OS. |
Parameters
The parameter for the CACHE control statement is:
SUBSYS= | specifies 1 to 16 cache subsystem IDs to be sampled |
---|---|
EXCLUDE= | specifies 1 to 16 cache subsystem IDs to be excluded. For SUBSYS and EXCLUDE parameters, a cache subsystem ID is a four-digit hexadecimal string (for example, 03F5). When more than one subsystem ID is specified, they must be separated by commas and the entire string must be enclosed in parentheses. The SUBSYS and EXCLUDE are mutually exclusive. Either the SUBSYS or the EXCLUDE parameter can be specified, but not both parameters simultaneously. When both these parameters are omitted, CMF MONITOR detects and monitors all active cache subsystems automatically. |
RECORDS= | specifies the cache sampler records that are created. Specify one or more of the following values. If you specify more than one value, separate the values with commas and enclose the value string in parentheses.
