RC= through RVFY= procedure parameters

The procedure parameters RC= through RVFY=, which are described in the following list, can be specified in procedures in the IMS environment.

RC= parameter for procedures
Use the RC= parameter in procedure to specify the message number for which information is to be searched.
RCF= parameter for procedures
Use the RCF= parameter in procedure to specify whether RACF® is to be used for transaction authorization or sign-on authorization checking. Valid values are A, C, N, S, T, and Y. If the RCF parameter is not specified, the default is the value specified at system definition.
RCFTCB= parameter for procedures
Use the RCFTCB= parameter in procedure to specify a number between 1 and 20 indicating how many RCF TCBs are defined in your system.
RCLASS=identifier parameter for procedures
Use the RCLASS=identifier parameter in procedure to specify a 1- to 7-character alphanumeric subsystem identifier for the RACF resource classes for this IMS subsystem. Use this parameter to uniquely identify the resource classes for this IMS subsystem in RACF.
RDMNM=name parameter for procedures
Use the RDMNM=name parameter in procedure to specify the Recovery Data Manager PROCLIB member name. If this optional parameter is not specified, the default RDM is used. If the Recovery Data Manager PROCLIB member is not found, IMS Database Recovery Facility uses default values.
RDS= parameter for procedures
Use the RDS= parameter to specify the buffer size to be used for the restart data set (IMS.RDS).
READNUM= parameter for procedures
Use the READNUM= parameter in procedure to specify the number of input devices that are to be used for IMS Database Recovery Facility. The allowable range is 1 through 99. The default value is 3.
RECA= parameter for procedures
Use the RECA= parameter in procedure to specify the number of receive-any buffers (1 to 500). This parameter overrides what is specified in the RECANY= parameter on the COMM macro.
RECASZ= parameter for procedures
Use the RECASZ= parameter in procedure to specify a 1- to 5-digit number indicating the size of the receive-any buffers. Valid values are from 112 to 30720.
RES= parameter for procedures
Use the RES= parameter in procedure to specify whether (Y) or not (N) the PSBs or DMBs defined in system definition macros APPLCTN or DATABASE as RESIDENT should be made resident during system initialization. Valid values are Y, or N. The default is Y.
REST=nn parameter for procedures
Use the REST=nn parameter in procedure to specify a 2-digit number greater than 00 to indicate from which set of utility control statements starts processing. A specification of 00 indicates no restart.
RGN= parameter for procedures
Use the RGN= parameter in procedure to specify the region size for this execution. For Fast Path, the default is 100K.
RGSUF=xxx parameter for procedures
Use the RGSUF=xxx parameter in procedure to specify a 3-character suffix for DFSPBxxx.
RMINIT= parameter for procedures
Use the RMINIT= parameter in procedure to specify a 3-character suffix for the RM initialization parameters PROCLIB member, CSLRIxxx. This parameter can be specified only as an execution parameter. The default suffix is 000.
RMNAME= parameter for procedures
Use the RMNAME= parameter in procedure to specify the name for the RM address space.
RRS= parameter for procedures
Specifies whether (Y) or not (N) the registration and connection to z/OS Resource Recovery Services (RRS) should be made. Valid values are Y, or N. The default is N.
RST= parameter for procedures
Use the RST= parameter in procedure to specify UCF restart. A value of 0 (no) or 1 (yes) must appear in the generated JCL statement for this parameter. Valid values are 0, or 1.
RVFY= parameter for procedures
Use the RVFY= parameter in procedure to specify whether password reverification is activated (Y) or not (N). Valid values are Y, or N. The default is N.
