Example 1: obtaining an LSR pool above 16 megabytes

z/OS DFSMS Macro Instructions for Data Sets
SC23-6852-02

This example shows how both a local shared resource pool and a BLDVRP parameter list residing above 16 megabytes are obtained.
POOL1  BLDVRP  BUFFERS=(1024(5)),                                       x
               STRNO=4,                                                 x
               TYPE=LSR,                                                x
               MODE=31,                                                 x
               RMODE31=ALL
The BLDVRP parameters are:
  • BUFFERS specifies there is one buffer pool in the resource pool. This buffer pool contains 5 buffers, and each of these buffers is 1024 bytes.
  • STRNO specifies 4 place holders are required for the data sets to share the resource pool.
  • TYPE specifies a local resource pool is built.
  • MODE specifies a parameter list is generated that may reside above or below 16 megabytes. The value of 31 must be coded if the parameter list resides above 16 megabytes.
  • RMODE31 specifies the location in storage for the I/O buffers and I/O related control blocks of the LSR pool.

To connect the LSR pool to the data set, you must code the LSR and SHRPOOL parameters on the ACB. See ACB—Generate an access method control block at assembly time.
