You can manipulate the replication cycle patterns to fit your needs by setting the following parameters in the symreplicate options file:

Parameters

SYMCLI_REPLICATE_CYCLE=CycleTime

CycleTime is a timer that specifies the period of time in minutes or hours:minutes (hh:mm) between when each copy action starts and when it starts again (how often the copy reoccurs). For example, a CycleTime of 120 would initiate a new copy every 2 hours.

SYMCLI_REPLICATE_NUM_CYCLES= NumCycles

NumCycles specifies the number of replication cycles (copies) to perform before symreplicate exits. For example, a value of zero (the default) results in continuous cycling until the symreplicate stop command is issued.

SYMCLI_REPLICATE_CYCLE_DELAY= Delay

Delay specifies the minimum amount of time to wait between the end of one copy cycle and the beginning of the next. For example, a Delay of 20 would always force a wait of 20 minutes or more between cycles.

SYMCLI_REPLICATE_CYCLE_OVERFLOW= OvfMethod

OvfMethod specifies the behavior when the actual copy time of data and/or data transfer is so large that it exceeds the CycleTime value. The initial copy event has overflowed into the period that should be for the next copy cycle. Possible behavior values are:

• IMMEDIATE — When overflowed, starts a new cycle immediately after the current copy finishes.
• NEXT — When overflowed, waits for the copy to finish, and then starts at the next expiration time (CycleTime). (Starts the copies on multiples of the CycleTime parameter.)

Example

For example, if a 1-hour copy cycle completed in 1.5 hours, the next cycle could be set to begin immediately (IMMEDIATE) or in half an hour (NEXT).
