ACTLOGTYPE: Specifying the type of output data set to receive messages

Explanation: ACTLOGTYPE(SYSOUT(class) | DASD) is an optional parameter specifying the activity logs as either a SYSOUT data set or a DASD data set. The content of the log is free-form and can be scanned to produce a desired output.

Subparameter Explanation

SYSOUT(class) Messages are written out to a spool data set. For class, substitute an alphanumeric character for the class DFSMShsm is to use for output.

DASD

Subparameter	Explanation
SYSOUT(class)	Messages are written out to a spool data set. For class, substitute an alphanumeric character for the class DFSMShsm is to use for output.
DASD	DFSMShsm dynamically allocates DASD data sets with a unit name of SYSALLDA and a size of 20 tracks for primary allocation and 50 tracks for secondary allocation. Activity logs have names in the following form: `mcvtactn.Hmcvthost.function.Dyyddd.Thhmmss` where: mcvtactn = Activity log high-level qualifier, the default is HSMACT Hmcvthost = DFSMShsm host ID from the PROC statement, preceded by H function = Either CMDLOG, BAKLOG, DMPLOG, or MIGLOG Dyyddd = Year and day of allocation, preceded by D Thhmmss = Hour, minute, and second of allocation, preceded by T

DFSMShsm dynamically allocates DASD data sets with a unit name of SYSALLDA and a size of 20 tracks for primary allocation and 50 tracks for secondary allocation. Activity logs have names in the following form:

  mcvtactn.Hmcvthost.function.Dyyddd.Thhmmss

where:

mcvtactn = Activity log high-level qualifier, the default is HSMACT
Hmcvthost = DFSMShsm host ID from the PROC statement, preceded by H
function = Either CMDLOG, BAKLOG, DMPLOG, or MIGLOG
Dyyddd = Year and day of allocation, preceded by D
Thhmmss = Hour, minute, and second of allocation, preceded by T

SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.

SETSYS default: The SYSOUT class established by the SETSYS SYSOUT command.

DFSMShsm default: If you do not specify this parameter on any SETSYS command, the DFSMShsm default is SYSOUT. If you do not specify class for SYSOUT, the DFSMShsm default is A, one copy, and no special forms.

Notes:

If the SYSOUT class is modified with the SETSYS ACTLOGTYPE command, existing open SYSOUT activity logs are closed and new SYSOUT activity logs are opened using the output class specified with the command. For the DFSMShsm secondary address space, the new output class is used for subsequent secondary address spaces as they are started.
ACTLOGTYPE is supported for secondary address spaces.
If you need to replace HSMACT as the activity log high-level qualifier, refer to "Tuning DFSMShsm" in the z/OS DFSMShsm Implementation and Customization Guide.
