CICS IA command flow variables

The variables that are required to configure the Logstream and GDG data sets that are required by CICS® IA.

COUPLING FACILITY or DASD
You can choose to create your user logstream in a coupling facility or on DASD-only. This field defaults to CF.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change

LOGSTREAM QUALIFIER
The qualifier prefix for the CIUMTJNL logstream data sets that are used by the Command Flow Collector.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed and is set to the value that is specified for "HLQ for IA output data sets". End of change

LOGSTREAM DATA SET NAME HLQ.
The logstream HLQ, which is used for the logstreams. You can use the CICS default qualifier IXGLOGR. Ensure that an alias exists for the selected qualifier. This field defaults to IXGLOGR.

Start of changeREQUIRED for a Full configuration if you are defining a DASD logstream. For a Short configuration, this field is not displayed. End of change

LOGSTREAM HIGHOFFLOAD
The high offload limit when data in the logstream is offloaded to a data set. This field defaults to 80.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change

LOGSTREAM LOWOFFLOAD
The low offload limit that is used when data in the logstream is offloaded to a data set. This field defaults to 0.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change

LOGSTREAM RETENTION PERIOD
The retention period, in days, for data that is written to the logstream. This value is used with the AUTODELETE option when you create the logstream. The value can be in the range 0 - 999 days. This field defaults to 5.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change

LOGSTREAM AUTODELETE
If this field is set to YES, the data is automatically deleted from the logstream after a period determined by the LOGSTREAM RETENTION PERIOD. This field defaults to YES.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change

LOGSTREAM STRUCTNAME
The name of the coupling facility structure name where the logstream is defined. This field defaults to LOG_USERJRNL_001.

Start of changeREQUIRED if you are defining a CF logstream. For a Short configuration, this field is not displayed. End of change

GDG DATA SET QUALIFIER
The qualifier prefix for the CICS IA GDG data sets that are used by the CICS IA command flow collector.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed and is set to the value that is specified for "HLQ for IA output data sets". End of change

NUMBER OF GDG DATASETS
Specifies the maximum number, 1 - 255, of GDSs that can be associated with the GDG being defined. This field defaults to 3.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change

GDG DELETE OPTION
Specifies what action is taken for a generation data set when the data set is uncataloged from the GDG base as a result of NOEMPTY processing. If this field is set to SCRATCH, the oldest data set is physically deleted and uncataloged. If this field is set to NOSCRATCH, the data set is uncataloged but not physically deleted. This field defaults to SCRATCH.

Start of changeREQUIRED for a Full configuration. For a Short configuration, this field is not displayed. End of change
