BPTEXT - Size of Text Segments in Natural Buffer Pool

This Natural profile parameter specifies the size of the segments into which the text pool area of the Natural buffer pool is divided.

Possible settings 1, 2, 4, 8, 12 or 16 Size of the buffer pool text segments in KB.
Default setting 4  
Dynamic specification yes This parameter can only be specified dynamically.
Specification within session no  


  1. This Natural profile parameter corresponds to the TXTSIZE specification of the BPI profile parameter or the NTBPI macro.
  2. Internally, the BPTEXT specification is converted into an equivalent BPI specification; for example: BPTEXT=4 is converted into BPI=(TYPE=NAT,SEQ=0,TXTSIZE=4).
  3. The BPTEXT parameter only applies to the primary Natural buffer pool (TYPE=NAT, SEQ=0). In the case of a global buffer pool, it is ignored. If there is a primary buffer pool with SEQ=0 in the Natural parameter module, only the TXTSIZE setting of this buffer pool is updated.
  4. In multi-user environments (for example, under CICS), the BPTEXT parameter only affects the very first Natural session, which initializes the local buffer pool.
  5. For general information on the Natural buffer pool, see Natural Buffer Pool in the Operations documentation.
