Changing SMF recording

The MVS system operator or MVS system programmer can dynamically change OAM SMF recording using one of the following two methods:

Update the SMF PARMLIB member (SMFPRMxx) to include the OAM SMF record subtypes:
SYS(TYPE(85(2:3)))
and activate the SMF PARMLIB member (SMFPRMxx) by entering the following MVS operator SET command:
SET SMF=xx

Note: The above example activates the OAM SMF recording for subtypes 2 and 3.
Update the SMF options dynamically by entering the following MVS operator SETSMF command:
SETSMF SYS(TYPE(85(4:6)))

Note: The above example activates the OAM SMF recording for subtypes 4, 5, and 6.

Below are several examples of the format of the SETSMF command to activate various OAM SMF record subtypes from an MVS console:

To exclude collecting all OAM SMF records, enter the following command:
SETSMF SYS(NOTYPE(85)))
To activate all OAM SMF record subtypes for the OSREQ macro application programming interface (subtypes 1–10), enter the following command:
SETSMF SYS(TYPE(85(1:10)))
To activate the OAM SMF record subtype for the OSMC storage group processing (subtype 32), enter the following command:
SETSMF SYS(TYPE(85(32)))
To activate the OAM SMF record subtype for the OSREQ RETRIEVE (subtype 3), LCS optical volume mount (subtype 72), and LCS optical read request (subtype 75), enter the following command:
SETSMF SYS(TYPE(85(3,72,75)))
To activate the OAM SMF record subtypes to track all optical library subsystem activity: optical cartridge entry (subtype 68), optical cartridge eject (subtype 69), optical volume audit (subtype 71), optical volume mount (subtype 72) and optical volume demount (subtype 73), enter the following command:
SETSMF SYS(TYPE(85(68,69,71,72,73)))
To activate the OAM SMF record subtypes to track all objects being retrieved from tape: OSREQ RETRIEVE (subtype 3) and LCS tape read requests (subtype 79), enter the following command:
SETSMF SYS(TYPE(85(3,79)))
