Dictionary Database Structure DICTRDF Fields
BUFFER-SIZE buffer size of an unstructured file in bytes. BUFFER-SIZE
redefines BLOCK-SIZE. Value must be 512, 1,024, 2,048, or 4,096 bytes; the
default is 4,096 bytes.
BLOCK-SIZE-OBJECT if block size is defined by a constant, contains the object
number of the constant; otherwise, it is 0.
BUFFER-SIZE-OBJECT if buffer size is defined by a constant, contains the object
number of the constant; otherwise, it is 0.
ICOMPRESS contains the ASCII character Y (yes) or N to indicate whether the
user has selected the index compression attribute for this file. The default for this
field is N.
DCOMPRESS contains the ASCII character Y (yes) or N to indicate whether the
user has selected the data compression attribute for this file. The default for this
field is N.
MAXEXTENTS the maximum number of extents this file can have. MAXEXTENTS
contains an integer between 1 and 978. The default value for MAXEXTENTS is
100.
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
one of the following:
Y (yes)
N (no)
D (follow the default)
If you select Y, then write requests are buffered in the disk-process cache rather
than forced to disk at each request. The default value is Y for audited files, N for
nonaudited files.
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. The default for
this field is N.
VERIFIED-WRITES contains Y (yes) to indicate disk writes are verified or N (no)
to indicate they are not. The default for this field is N.
SERIAL-WRITES contains Y (yes serial) or N (no parallel) to indicate whether
mirror disk writes are serial or parallel. The default for this field is N (parallel).
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. The default for this field is Y (odd unstructured). For information
