Specify a Record Type

Use the SETOPTION MIM STATCOLLECT command to specify the type of statistical records to be collected.

Specify the SUBTYPE operand to select specific record subtypes for a facility, or specify ALL to collect records for all record subtypes available under that facility. The record subtypes correspond directly to the reports available for each facility.

The following are record subtypes for the CA MIM facility:

Record Subtype

Facility

Description of Report

CF

CA MIM

CA MIM Control File Performance report is used to assist you in tuning the CA MIM control files.

FC

CA MIM

CA MIM Control File I/O report details activity in the CA MIM control files. It can be used in conjunction with the CF report to assist with control file placement.

VF

CA MIM

CA MIM Virtual Control File I/O Performance report details the activity on the CTC devices.

For example, the following command tells CA MIM to collect statistics for the report subtype CF:

SETOPTION MIM STATCOLLECT(SUBTYPE=CF)

Important! To activate the record collection process for all record subtypes, you must repeat this procedure for each subtype, specifying the SETOPTION STATCOLLECT command and the facility associated with that record subtype.
