PRDR= through QTU= procedure parameters

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

PRDR=name parameter for procedures
Use the PRDR=name parameter in procedure to specify the name of the IMSRDR procedure in IMS.PROCLIB, or SYS1.PROCLIB, used in /START REGION commands. The name can be up to 8 characters in length. The default is IMSRDR.
PREINIT=xx parameter for procedures
Use the PREINIT=xx parameter in procedure to specify a 2-character suffix for DFSINTxx, the IMS.PROCLIB member that lists the preinitialization modules that are to receive control.
PREMSG= parameter for procedures
Use the PREMSG= parameter in procedure to specify whether (Y) or (N) you want to receive or suppress the DFS000I prefix message that precedes all DBCTL system messages and command responses. Valid values are Y, or N. Y is the default.
PRLD=xx parameter for procedures
Use the PRLD=xx parameter in procedure to specify a 2-character suffix for DFSMPLxx, the IMS.PROCLIB member identifying the modules to be preloaded in the region or partition.
PSB= parameter for procedures
Use the PSB= parameter in batch procedures to specify an optional PSB name when the PSB name and application program name are different. Use the PSB= parameter in online procedures to specify the amount of subpool 231 storage to be allocated to the PSB pool.
PSBW= parameter for procedures
Use the PSBW= parameter in procedure to specify the amount of subpool 231 storage to be allocated to the PSB work area pool.
PST= parameter for procedures
Specifies the number of partition specification tables (PSTs) to be allocated during system initialization. This number can be between 0 and the number specified on the MAXPST= control region parameter. The default is 0.
PSWDC= parameter for procedures
Use the PSWDC= parameter in procedure to specify whether mixed-case passwords are supported. Valid values are M, U, and R. The default is R.
PWFI= parameter for procedures
Use the PWFI= parameter in procedure to specify the pseudo-wait-for-input (PWFI) parameter. Valid values are Y, or N. N is the default.
QBUF= parameter for procedures
Use the QBUF= parameter in procedure to specify the 1- to 4-digit number of message queue buffers in subpool 0 to be allocated to the queue pool.
QBUFHITH= parameter for procedures
Use the QBUFHITH= parameter in procedure to specify a 1- to 3-digit number from 1 to 100 that establishes the high threshold percentage for the message queue buffer. The default is 80%.
QBUFLWTH= parameter for procedures
Use the QBUFLWTH= parameter to specify a 1- to 3-digit number from 1 to 100 that establishes the low threshold percentage for the message queue buffer. The default is 50%.
QBUFMAX= parameter for procedures
Use the QBUFMAX= parameter in procedure to specify the 1- to 7-digit number that indicates the maximum number of message queue buffers for the queue pool.
QBUFPCTX= parameter for procedures
Use the QBUFPCTX= parameter in procedure to specify a 1- to 3-digit number in the range of 1 to 100 that establishes the percentage of the originally allocated message queue buffers that are dynamically expanded when the limit specified by the QBUFHITH= parameter is reached. The default is 20%.
QBUFSZ= parameter for procedures
Use the QBUFSZ= parameter in procedure to specify a 1- to 5-digit number that represents the size in bytes of the message queue buffers (in core buffers) used by the queue manager.
QTL= parameter for procedures
Use the QTL= parameter in procedure to specify the lower threshold percentage (1 to 99) for each message queue data set in a non-shared-queues environment, or the lower threshold percentage (1 to 99) for the device relative record number (DRRN) in-use count in a shared-queues environment.The default value is 60%.
QTU= parameter for procedures
Use the QTU= parameter in procedure to specify the upper threshold percentage (2 through 100) for each message queue data set in a non-shared-queues environment, or the upper threshold percentage (2 to 100) for the DRRN in-use count in a shared-queues environment. The default value is 75%.
