[damchlmt logical-file-name threshold-for-the-number-of-cache-blocks]

Use this command to specify the upper limit for the number of cache blocks that can be managed by a single DAM file.

logical-file-name~<identifier of 1 to 8 characters>

Specify the name of the logical file that validates a threshold for the number of cache blocks. You need to define the logical file name specified here using the damfile command beforehand.

threshold-for-the-number-of-cache-blocks~<unsigned integer>((0-4000000))

Specify a threshold for the number of cache blocks that are managed by the specified logical file. If you do not specify this argument, the DAM service secures cache blocks until the shared memory resource is used up.

• The damchlmt command is valid only for the logical file that is defined using the damfile command. Therefore, you need to define the target logical file name using the damfile command beforehand. If you specify a threshold for the number of cache blocks before you specify the target logical file using the damfile command, the threshold will not be valid.
• If you specify the damchlmt command more than once for a single logical file name, operation is not guaranteed.
