CODE EXAMPLE 4-2 shows lines in a releaser.cmd file specifying that only the file’s

residence age be considered, and that the modification age and the access age be

ignored, when the release priority of a file is calculated.

After a file’s age-related priority is calculated, it is multiplied by the file’s size-

related priority. The size-related priority is calculated as described in the following

section.

File Size

The releaser considers a file’s size when determining the size-related component of a

file’s release priority. The size of the file (in 4-kilobyte blocks) is multiplied by the

weight specified for the weight_size directive to determine the size-related

component of a file’s release priority.

The format of the weight_size directive is as follows:

For float, specify a floating-point number from 0.0 through 1.0. By default, float = 1.0.

CODE EXAMPLE 4-3 shows a releaser.cmd file specifying that the file size is to be

ignored for all files in the samfs1 and samfs2 file system when the release priority

of a file is calculated.

CODE EXAMPLE 4-2 releaser.cmd File Fragment

weight_age_residence = 1.0

weight_age_modify = 0.0

weight_age_access = 0.0

weight_size = float

CODE EXAMPLE 4-3 releaser.cmd File

# releaser.cmd file

logfile = /var/adm/default.releaser.log

weight_size = 0.0

fs = samfs1

weight_age = 1.0

logfile = /var/adm/samfs1.releaser.log

fs = samfs2

weight_age_modify = 0.3

weight_age_access = 0.03

weight_age_residence = 1.0

logfile = /var/adm/samfs2.releaser.log
