DLINM= through EXVR= procedure parameters

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

DLINM= parameter for procedures
Use the DLINM= parameter in procedure to specify the member in SYS1.PROCLIB containing the procedure for the optional DL/I address space. The default is DLISAS.
DLIPSB= parameter for procedures
When the DL/I address space option (LSO=S) is specified, two program specification block pools are used. CSAPSB specifies the size of pool in the z/OS® common storage area (CSA), and DLIPSB specifies the size in the DL/I address space. In an LSO=S system, the PSB= parameter is ignored.
DLQT= parameter for procedures
Use the DLQT= parameter in procedure to specify a 1- to 3-digit number for the size of the dead letter queue, in days. Valid values are from 0 to 365. The default is 60. If you specify a null or invalid value, 60 is assumed.
DMB= parameter for procedures
Use the DMB= parameter in procedure to specify the amount of subpool 231 storage to be allocated to the data management block (DMB) pool.
DMHVF= parameter for procedures
Use the DMHVF= parameter in procedure to specify (in megabytes) how much storage in the Fast Path DEDB VSO emergency restart data space is to be page fixed. Valid values are from 0 to 99.
DPRTY= parameter for procedures
This parameter is ignored by z/OS, but retained in IMS for compatibility.
DSCT= parameter for procedures
Use the DSCT= parameter in procedure to specify a 1-character suffix identifying the user-supplied descriptor table, DFSDSCTy, in IMS.PROCLIB. The default is 0.
DYNP= parameter for procedures
Use the DYNP= parameter in procedure to specify a value for the upper expansion limit of the TM dynamic storage private buffer pool.
EMHB= parameter for procedures
Use the EMHB= parameter in procedure to specify a value for the upper expansion limit of the Fast Path expedited message handler buffer pool.
EMHL= parameter for procedures
Use the EMHL= parameter in procedure to specify a 1- to 5-digit number for the length of the Fast Path expedited message handler buffer.
ENVIRON= parameter for procedures
Use the ENVIRON= parameter in procedure to specify the name of the PROCLIB member that contains the JVM environment settings. A sample member DFSJVMEV is supplied in the IMS sample library. ENVIRON is a required parameter. However, this parameter is ignored if the //STDENV DD statement is present.
EPCB= parameter for procedures
Use the EPCB= parameter in procedure to specify the amount of subpool 231 storage to be allocated to the EPCB pool.
ETO= parameter for procedures
Use the ETO= parameter in procedure to specify whether IMS Extended Terminal Option (IMS ETO) is enabled. Valid values are N, M, and Y. The default is N.
EXCPVR= parameter for procedures
Use the EXCPVR= parameter in procedure to specify whether (1) or not (0) the OSAM Database Buffer Pool is to be page fixed. A value of 0 or 1 must appear in the generated JCL statement for this parameter.
EXVR= parameter for procedures
Use the EXVR= parameter in procedure to specify whether (1 or Y) or not (0 or N) the Queue Manager buffer pools are to be long-term page fixed.
