EDS Maintenance Processor

LOAD accepts the following keywords:

Workload

GROUP, SYSTEM, OTHER (see Table 10:

Workload Keywords on page 70)

Resource record type

All resource record types, such as RDEV and RBUF. See Table 9: Resource Panel Types on page 68 for a complete list of resource record types.

Date/time

BAND/RANGE, DAYOFWK, ENDDATE, ENDTIME, LASTMONTH, LASTWEEK, STARTDATE, STARTTIME, THISMONTH, THISWEEK, TODAY, YESTERDAY (see Table 11: Date/Time Keywords on page 75)

Miscellaneous keywords

EXCLUDE (see Exclude date and times (EXCLUDE command)on page 138), SMF, SYSID

Note: You only need to specify SYSID and SMF keywords once for all LOAD commands. The loading process uses the last occurrence of either parameter.

Delete records from the EDS (PURGE command)

The PURGE command deletes records (for a specific type of workload or resource panel type) from the EPILOG datastore. PURGE typically deletes all data records before a certain date, which allows you to reorganize the EPILOG datastore to make more room for current data.

Note: EPILOG collection cannot reuse purged VSAM space until you use IDCAMS REPRO to unload, recreate, and reload the EPILOG datastore.

The PURGE command can take a long time to work when you delete a large number of records. It is generally far more efficient to REPRO the cluster to a non-VSAM sequential dataset and then use the KEBUTIL utility to copy only the records you want back into an empty cluster (see EDS Utility Processoron page 136). This method uses less I/O and CPU resources, but allows you to exclude records only by date and time, not by record type.

The JCL in Figure 40 is similar to the JCL in: rhilev.midlev.RKANSAM(KEIDBPRG).
