This Natural profile parameter enables the Natural administrator to define the general default compression optimization in order to preserve main storage for the sessions which are currently processing and to improve the performance of Natural.
In addition, the type of storage compression optimization can be defined
specifically for individual buffer types, using the parameter
CMPR of the NTBUFID macro in the
NATCONFG
module. The setting of this macro parameter overrides the general default
setting of profile parameter CMPR. For further
information, see
Customization
of Buffer Characteristics in the
Operations documentation.
| Possible settings | OPT0 |

OPT2 |
Compression with optimization by tiles with identical characters. The tile size is 128 bytes. | |
(OPT2,nnn) |
Compression with optimization by tiles with
identical characters. The tile size is a multiple of 128 bytes.
