BPSIZE - Size of Natural Local Buffer Pool

This Natural profile parameter specifies the size of the Natural local buffer pool.

Possible settings 256 - 2097151 Size of the Natural local buffer pool in KB.
Default setting 256  
Dynamic specification yes This parameter can only be specified dynamically.
Specification within session no  

Notes:

  1. This Natural profile parameter corresponds to the SIZE specification of the BPI profile parameter or the NTBPI macro.
  2. BPSIZE only applies to the primary Natural local buffer pool (TYPE=NAT, SEQ=0). For a global buffer pool, it is ignored. If there is a primary buffer pool with SEQ=0 in the Natural parameter module, only the SIZE setting of this buffer pool is updated.
  3. In multi-user environments (for example, under CICS), the BPSIZE parameter only affects the very first Natural session, which initializes the local buffer pool.
  4. Under Com-plete, the size of a local buffer pool is set as described in the corresponding Natural installation documentation.
  5. Under BS2000/OSD, the size of a local buffer pool is specified with the parameter SIZE of the ADDON macro.
  6. Internally, the BPSIZE specification is converted into an equivalent BPI specification; for example: BPSIZE=1500 is converted into BPI=(TYPE=NAT,SEQ=0,SIZE=1500).
  7. For general information, see Natural Buffer Pool in the Operations documentation.
