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 | 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:
where:
|
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.
