This Natural profile parameter specifies the size of the buffer pool cache (in KB) for a Natural local buffer pool.
Possible settings | 0 |
If BPCSIZE=0 is
set, no buffer pool cache is used.
|
|
---|---|---|---|
100 - 2097148
(2 GB - 4 KB) |
The buffer pool cache size
in KB for cache in data space; that is, with C64 =OFF .
Note: |
||
100 - 58720256
(56 GB) |
The buffer pool cache size
in KB for cache "above the bar"; that is, with
C64 =ON .
Note: |

Default setting | 0 |
By default, no buffer pool cache is used. | |
Dynamic specification | yes | This parameter can only be specified dynamically. | |
Specification within session | no |
Notes:
CSIZE
subparameter of
the BPI
profile
parameter or NTBPI
macro.
BPCSIZE
specification is
converted into the equivalent BPI
specification, for
example: BPCSIZE=4000
is converted into
BPI=(TYPE=NAT,SEQ=0,CSIZE=4000)
.
BPCSIZE
parameter applies to the
primary Natural buffer pool (TYPE
=NAT
,
SEQ
=0
) only.
In the case of a Natural global buffer pool, it is ignored. If there is a
primary buffer pool with SEQ=0
in the
Natural
parameter module, only the cache size setting of this buffer pool is
updated.
BPCSIZE
parameter affects the very first Natural session only,
which initializes the Natural local buffer pool.
