HRUDCRX Commands
HRUDCRX supports the following commands:
• BIND either places data into cache or releases it from cache.
• COUNTS displays the cache volume or dataset statistics. This command can
also reset the counters if necessary.
• STATUS displays the cache status information.
• DSMODE either defines the tracks for dataset statistics or releases that
definition.
• HRUDCRX commands can also be combined using JCL .
Using Bind to Place or Release Data From the Cache
Figure 4-1 illustrates BIND command parameters.
• ENABLE will place data into a specified area of cache.
• DISABLE will release data from cache.
• You can specify the target data either by DDNAME (using volume, unit and
disp number), VOLUME (volume serial number), or DEVICE (device
number).
• You can specify the cache area by VTOC, CCHH, DATASET, CCHH or
SYSTEMDS (either physical VTOC, INDEX VTOC, or VVDS). If you
specify ENABLE, you must also specify one of these parameters.
• DKU|FREESPACE is used if you want to release tracks from cache
(DISABLE). The DKU command releases all tracks on a particular volume.
FREESPACE releases all eccentric areas on a volume. DKU is the default
value.
• PRIO is used to specify tracks to be bound into priority mode (ENABLE). If
you do not specify PRIO, BIND mode is the default.
