`PERIODIC_SCHEDULE` Environment Variable

The value of PERIODIC_SCHEDULE follows the same format as the crontab file. Specify the variable value as a string of five fields enclosed in double quotation marks, with each field separated by a space:

"minutes hours day-of-month month day-of-week"

Table 8–3 Periodic_Schedule Variable Values


Variable	Value
`minutes hours`	Specifies start time in number of minutes (0–59) after the hour and the hour (0–23)
`day-of-month`	Specifies the day of the month when ASET should be run, with values from 1–31
`month`	Specifies the month of the year when ASET should be run, with values from 1–12
`day-of-week`	Specifies the day of the week when ASET should be run, with values from 0–6; Sunday is day 0

The following rules apply:

You can specify a list of values, each delimited by a comma, for any field.
You can specify a value as a number, or you can specify it as a range; that is, a pair of numbers that are joined by a hyphen. A range states that the ASET tasks should be executed for every time that is included in the range.
You can specify an asterisk (*) as the value of any field. An asterisk inclusively specifies all possible values of the field.

The default entry for the PERIODIC_SCHEDULE variable causes ASET to execute at 12:00 midnight every day:

PERIODIC_SCHEDULE=”0 0 * * *”
