File processing attributes for the CSD are defined in the following system initialization parameters:
- CSDACC
- The type of access allowed.
- CSDBKUP
- Specify whether the CSD is eligible for BWO. This parameter
is ignored if CSDRLS=YES--CICS uses the BWO parameter in the
ICF catalog instead. CICS® also uses the BWO parameter in
the ICF catalog for non-RLS mode CSDs if the LOG parameter in the
ICF catalog specifies either UNDO or ALL.
- CSDBUFND
- The number of buffers for CSD data. Ignored if CSDRLS=YES.
- CSDBUFNI
- The number of buffers for the CSD index. Ignored if CSDRLS=YES.
- CSDDISP
- The disposition of the CSD data set.
- CSDDSN
- The JCL data set name (DSNAME) of the CSD.
- CSDFRLOG
- A forward recovery journal identifier. This parameter is ignored
if CSDRLS=YES, or if the recovery attributes are defined in the ICF
catalog on the LOG parameter, in which case LOGSTREAMID from the ICF
catalog is used instead.
- CSDINTEG
- The level of read integrity to be used for a CSD accessed in
RLS-mode.
- CSDJID
- An identifier for automatic journaling.
- CSDLSRNO
- A VSAM local shared resource pool. Ignored if CSDRLS=YES.
- CSDRECOV
- Whether or not the CSD is recoverable. This parameter is ignored
if CSDRLS=YES and CICS uses the LOG parameter from the
ICF catalog instead. If LOG is "undefined", any attempt to
open the CSD in RLS mode fails.
If CSDRLS=NO, this parameter is
used only if LOG in the ICF catalog is "undefined." If LOG
in the ICG catalog specifies NONE, UNDO, or ALL, the LOG parameter
overrides CSDRECOV.
- CSDRLS
- Whether the CSD is accessed in RLS or non-RLS mode.
- CSDSTRNO
- The number of strings for concurrent requests. CSDSTRNO is ignored
if CSDRLS=YES and 1024 is assumed.
These parameters are described in greater detail in Specifying CICS system initialization parameters.
