DBBF= through DIRCA= procedure parameters

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

DBBF= parameter for procedures
Use the DBBF= parameter in procedure to specify the maximum number of Fast Path buffers.
DBD= parameter for procedures
Use the DBD= parameter in procedure to specify the Fast Path Data Entry Database (DEDB) DBD name. DBD= can be 1 - 8 characters.
DBFP= parameter for procedures
Use the DBFP= parameter in procedure to specify a 1- to 4-digit value that determines how often the IMS Fast Path buffer pool manager can page free unneeded buffers. The default value of 0 indicates that any unneeded buffers are page freed at each dependent region termination.
DBFX= parameter for procedures
Use the DBFX= parameter in procedure to specify a 1- to 5-digit number of additional buffers (not separate pools) from DBBF to be set aside and page-fixed at control region initialization. The default value is 10.
DBLDL= parameter for procedures
Use the optional DBLDL= parameter in procedure to specify the maximum number of BLDL entries to be kept for application modules that are not preloaded. The default is 20. The maximum value allowed is 9999.
DBRC= parameter for procedures
Use the DBRC= parameter in procedure to specify whether database recovery control is to be used during this execution of IMS.
DBRCGRP=id parameter for procedures
Use the DBRCGRP=id parameter in procedure to specify the 1- to 3-character identifier (ID) assigned to a group of DBRC instances that access the same RECON data set in an IMSplex.
DBRCINIT=nnn parameter for procedures
Use the DBRCINIT=nnn parameter in procedure to specify a 3-character suffix for the DBRC initialization parameters PROCLIB member, DSPBIxxx. The default suffix is 000.
DBRCNM= parameter for procedures
Use the DBRCNM= parameter in procedure to specify the member in SYS1.PROCLIB containing the procedure for the DBRC address space. The default is DBRC.
DBRSE= parameter for procedures
Use the DBRSE= parameter in procedure to specify the 8-character RSENAME.
DBWP= parameter for procedures
Use the DBWP= parameter in procedure to specify the amount of subpool 231 storage to be allocated to the database work area pool.
DC=nnn parameter for procedures
Use the DC=nnn parameter in procedure to specify the 3-character suffix for the DFSDCxxx member in IMS.PROCLIB. The default is 000.
DEADLOK='iiii,kkkk' parameter for procedures
Use the DEADLOK='iiii,kkkk' parameter in procedure to specify the local deadlock-detection interval in seconds or milliseconds (iiii) and the number of local cycles (kkkk) that are to occur before a global detection is initiated.
DESC= parameter for procedures
Use the DESC= parameter in procedure to specify the message descriptor code to be assigned to the IMS system console messages.
DFSDF=xxx parameter for procedures
Use the DFSDF=xxx parameter in procedures to specify the 3-character suffix of the DFSDFxxx PROCLIB member that you want to use for this procedure.
DIRCA= parameter for procedures
Use the DIRCA= parameter in procedure to specify the size of the dependent region interregion communication area (DIRCA). The size specified must be a 3-digit number (for example, 001).
