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.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
- LOGSTREAM QUALIFIER
- The qualifier prefix for the CIUMTJNL logstream data sets that
are used by the Command Flow Collector.
REQUIRED 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".
- 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.
REQUIRED for a Full configuration if you are defining a DASD logstream. For a Short configuration, this field is not displayed.
- LOGSTREAM HIGHOFFLOAD
- The high offload limit when data in the logstream is offloaded
to a data set. This field defaults to 80.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
- 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.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
- 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.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
- 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.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
- LOGSTREAM STRUCTNAME
- The name of the coupling facility structure name where the logstream
is defined. This field defaults to LOG_USERJRNL_001.
REQUIRED if you are defining a CF logstream. For a Short configuration, this field is not displayed.
- GDG DATA SET QUALIFIER
- The qualifier prefix for the CICS IA
GDG data sets that are used by the CICS IA
command flow collector.
REQUIRED 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".
- 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.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
- 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.
REQUIRED for a Full configuration. For a Short configuration, this field is not displayed.
