DICTRDF (Record Definition File)
MAXEXTENTS-OBJECT If MAXEXTENTS is defined by a constant,
contains the object number of the constant;
otherwise, it is 0.
BUFFERED Indicates the mode of handling write requests.
BUFFERED can be B (yes), N (no), or D (follow
the default). The default value is B for audited files
and N for nonaudited files.
If you select B, write requests are buffered in the
disk-process cache rather than forced to disk at
each request.
AUDIT-COMPRESS Contains the ASCII character Y (yes) to indicate
the audit-checkpoint record is to be compressed
or N (no) to indicate it is not to be compressed.
The audit-checkpoint record contains a copy of an
audited data record both before and after an
update. The audit-checkpoint record is
compressed by omitting the unchanged portions
of the data record. N is the default.
VERIFIED-WRITES Contains Y (yes) to indicate disk writes are
verified or N (no) to indicate they are not. N is the
default.
SERIAL-WRITES Contains Y (yes–serial) or N (no–parallel) to
indicate whether mirror disk writes are serial or
parallel. N is the default.
ODD-UNSTRUCTURED Contains Y (yes–odd unstructured) or N (no–even
unstructured) to indicate whether the file is to be
created as odd unstructured or even unstructured.
Y is the default. For information about even
unstructured and odd unstructured files, see the
File Utility Program (FUP) Reference Manual.
* In H06.28/J06.17 RVUs with specific SPRs and later RVUs, the default primary extent size for DDL is 16 pages
if a block of 32768 bytes is provided for key-sequenced files.
For a list of the required H06.28/J06.17 SPRs, see SPR Requirements for Increased Enscribe Limits for the
H06.28/J06.17 Release.
** In H06.28/J06.17 RVUs with specific SPRs and later RVUs, the block size must be 512, 1024, 2048, 4096, or
32768 bytes. The block size of 32768 bytes is internally stored as the value -32768 in this field.
For a list of the required H06.28/J06.17 SPRs, see SPR Requirements for Increased Enscribe Limits for the
H06.28/J06.17 Release.
