How to Set the Max Continuous Sync (secs) Registry Value

The Max Continuous Sync (secs) registry value defines the maximum amount of time that the Active Directory Connector replicates uninterruptedly. Max Continuous Sync (secs) works in conjunction with the Sync Sleep Delay (secs) registry value, which defines the amount of time that the Active Directory Connector sleeps after it reaches the Max Continuous Sync (secs) registry value, and also the amount of time before the next cycle starts. For example, if you set Max Continuous Sync (secs) to 1200 (20 minutes) and Sync Sleep Delay (secs) to 300 (5 minutes), the Active Directory Connector works for 20 minutes, then sleeps for 5 minutes, then works another 20 minutes, and so on.

For detailed instructions about how to set the Sync Sleep Delay (secs) registry value, see How to Set the Sync Sleep Delay (secs) Registry Value.

Before You Begin

Before you perform the procedure in this topic, be aware of the following:

• These changes affect all the connection agreements running on the ADC server, and they may adversely affect other Active Directory applications. Setting this value too high can have an adverse effect on Active Directory and other applications. It is recommended that you set Max Continuous Sync (secs) to no more than 1200, or 20 minutes, and set Sync Sleep Delay (secs) to no more than 300, or 5 minutes.
