1) Description of attribute fields
Copy Queue Length
Indicates the number of log files that are waiting to be copied to the selected database copy. This field is only relevant to the passive database copy.
Replay Queue Length
Indicates the number of log files waiting to be replayed into the selected database copy. This field is only relevant to the passive database copy.
Activate the preference number
Displays the activation preference number. It is used during the active manager best Copy selection process and uses the Redistributeactivedatabases.ps1 script to redistribute the active mailbox database in the DAG to balance the DAG. The value of the activation preference is a number greater than or equal to 1, and 1 represents the highest priority. This number cannot be larger than the number of copies of the mailbox database.
Replay lag time (days)
Displays the time that the Microsoft Exchange Information Store Service should wait before replaying the log files that were copied by the Microsoft Exchange Replication service to the passive database copy. Setting the value of this parameter to greater than 0 creates a copy of the lag database. The default value for this parameter is set to 0 days, the maximum value is 14 days, and the minimum value is 0 days. Setting this value to 0 disables replay lag.
2. Use the shell to configure mailbox database copy Properties
This example configures the activation preference number for a mailbox database copy to 3.
Set-MailboxDatabaseCopy -Identity DB3\EX3 -ActivationPreference 3
This example configures the replay delay and truncation lag time for a copy of the database DB1 residing on Server1 to 1 days, with the activation preference number configured to 2.
Set-MailboxDatabaseCopy -Identity DB1\Server1 -ReplayLagTime 1.0:0:0 -Truncation
The above configuration can also be used in the graphical interface
