ALTER Parameter for Unstructured Files
The FUP process rounds the extent size up to the next full page.
0:maximum MEGABYTE[S]
specifies extent sizes in million-byte units. Possible values are:
The FUP process rounds the extent size up to the next full page.
PARTONLY
specifies that any changes you make with the ALTER command apply only to the
indicated file partition. If you reference a primary partition name, the extents are
altered only in the primary partition.
ALTER Parameter for Unstructured Files
These alter-option parameters are available for unstructured files:
BUFFERSIZE unstructured-buffer-size
is the internal buffer size to use when accessing the specified file. You can set the
BUFFERSIZE file attribute with this command (FUP ALTER) or with the FUP
CREATE and FUP SET commands. Possible values for unstructured-
buffer-size (in bytes) are:
FUP rounds the actual buffer size up to the nearest valid DP2 block size.
ODDUNSTR
changes an even unstructured file to an odd unstructured file.
Unstructured Enscribe files can be even or odd. FUP rounds up any odd byte
count that you give to an even unstructured file (for reading, writing, or positioning).
This is the default for unstructured files.
FUP does not round odd unstructured files up. You always read, write, or position
at the byte count you give.
To change an odd unstructured file to an even unstructured file, copy the odd file
into a new file that was created as even unstructured.
ALTER Guidelines
To receive the current file attributes for any file you want to alter, use the FUP
INFO command:
