Frequency Options
You can specify the interval between replications or the time of day when replication occurs for a replicate.

| Element | Purpose | Restrictions |
|---|---|---|
| interval | Time interval for replication | The smallest interval in minutes, in one of the
following formats:
|
| time | Specific time for replication | Time is given as a 24-hour clock. |
| Long Form | Short Form | Meaning |
|---|---|---|
| --immed | -i | Default. Replication occurs immediately. |
| --every= | -e | Replication occurs immediately and repeats at the frequency that is specified by interval. |
| --at= | -a | Replication occurs at the specified day and time. |
Usage
The frequency of replication is a property of a replicate. You can set the frequency of replication for a replicate when you define it or modify it. You can reset the frequency of all replicates in a replicate set when you define or modify a replicate set or define a template. For non-exclusive replicate sets, you can update the frequency of individual replicates separately.
If you do not specify a time, replication occurs immediately.
Intervals
- The number of minutes
To specify the number of minutes, specify an integer value greater than 0. For example, -e 60 indicates 60 minutes between replications.
If you specify the interval of time between replications in minutes, the longest interval is 1966020.
- The number of hours and minutes
To specify hours and minutes, give the number of hours, followed by a colon, and then the number of minutes. For example, -e 5:45 indicates 5 hours and 45 minutes between replications.
If you specify the length of time in hours and minutes, the longest interval is 32767:59.
Time of Day
Enterprise Replication always gives the time of day in 24-hour time. For example, 19:30 is 7:30 P.M. Enterprise Replication always gives time as the local time, unless the TZ environment variable is set. However, Enterprise Replication stores times in the global catalog in Greenwich Mean Time (GMT).
- Day of week
To specify a specific day of the week, give either the long or short form of the day, followed by a period and then the time. For example, --at=Sunday.18:40 or -a Sun.18:40 specifies that replication occurs every Sunday at 6:40 P.M.
The day of the week is given in the locale of the client. For example, with a French locale, you might have --at=Lundi.3:30 or -a Lun.3:30. The time and day are in the time zone of the server.
- Day of month
To specify a specific day in the month, give the date, followed by a period, and then the time. For example, 1.3:00 specifies that replication occurs at 3:00 A.M. on the first day of every month.
The special character L represents the last day of the month. For example, L.17:00 is 5:00 P.M. on the last day of the month.
- Daily
To specify that replication occurs each day, give only the time. For example, 4:40 specifies that replication occurs every day at 4:40 A.M.
