SET Parameters for Partitioned Files
[ NO ] DCOMPRESS
sets or clears key compression for data blocks. The default setting is NO
DCOMPRESS. The key offset must be 0 for key compression, and the maximum
record size is reduced by one byte.
[ NO ] ICOMPRESS
sets or clears key compression in index blocks. The default setting is NO
ICOMPRESS.
KEYLEN key-length
sets the primary-key length. Specify key-length as an integer in the range 1
through 255. To create key-sequenced file structures, you must specify KEYLEN,
or the creation attempt fails.
KEYOFF key-offset
sets the primary-key offset. Specify key-offset as an integer in the range 0
through 2034. The default setting for key-offset is 0.
QUEUEFILE
sets the queue file attributes. Queue files are a special type of key-sequenced file
with timestamps automatically added by DP2. Processes can queue and dequeue
records in a queue file. Queue files contain variable-length records that are
accessed by values in designated key fields. Unlike other key-sequenced files,
queue files have primary keys but cannot have alternate keys. The primary key for
a queue file includes an 8-byte timestamp. You can optionally add a user key. The
disk process inserts the timestamp when each record is inserted into the file and
maintains the timestamp during subsequent file operations.
LOCKLENGTH lock-length
sets the lock-length. Specify lock-length as an integer in the range 0 through
the value of KEYLEN. The default setting for lock-length is the value of
KEYLEN.
SET Parameters for Partitioned Files
The available value of create-param depends on the type of file you want to create.
These parameter values are described in section SET Parameters for All File Types
on
page 2-172. These options are available for partitioned files:
