LUMP= parameter for procedures

Use the LUMP= parameter in procedure to specify a value for the upper expansion limit of the LU 6.2 device manager private buffer pool and OTMA.

The value can be specified as 1- to 6-numeric characters, or 1- to 5-numeric characters followed by K (kilobyte), M (megabyte), or G (gigabyte). If K, M, or G is not specified, K is the default. The maximum value is 2G-1. The upper limit defaults to 2G-1 if any of the following statements is true:

  • The value specified is not large enough to hold the largest primary and secondary storage allocations that are defined.
  • The value specified exceeds 2G-1.
  • No value is specified.

The LUM code uses the pool for work area processing when not processing in the dependent region.

Some of the OTMA and APPC message processing modules have been updated to use DYNP for module dynamic storage. For more information, see the description of DYNP= in DYNP= parameter for procedures.
