This Natural profile parameter specifies the size of the Natural local buffer pool.
It corresponds to the SIZE specification of the
BPI profile
parameter or the NTBPI
macro.
Notes:
SIZE of the ADDON
macro.
| 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 |
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 NATPARM, only the SIZE setting of this
buffer pool is updated.
In multi-user environments (for example, under CICS), the
BPSIZE parameter only affects the very first Natural
session, which initializes the local buffer pool.
Internally, the BPSIZE specification is converted
into an equivalent BPI specification.
BPSIZE=1500
is converted into:
BPI=(TYPE=NAT,SEQ=0,SIZE=1500)
For general information, see Natural Buffer Pool in the Operations documentation.
