Defining CSD attributes

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.
