# 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. 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)`.
6. For general information, see Natural Buffer Pool in the Operations documentation.
