Recipe 12.6 Changing the Inter-Site Replication Interval

12.6.1 Problem

You want to set the schedule for replication for a site link.

12.6.2 Solution

These solutions assume the IP transport, but the SMTP transport could be used as well. Using a graphical user interface
  1. Open the Active Directory Sites and Services snap-in.

  2. Expand the Inter-Site Transport container.

  3. Click on the IP container.

  4. In the right pane, double-click on the site link you want to modify the replication interval for.

  5. Enter the new interval beside Replicate every.

  6. Click OK. Using a command-line interface

To change the replication interval, create an LDIF file named set_link_rep_interval.ldf with the following contents:

dn: cn=<LinkName>,cn=ip,cn=Inter-Site Transports,cn=sites, 
changetype: modify
replace: replInterval
replInterval: <NewInterval>

then run the following command:

> ldifde -v -i -f set_link_rep_interval.ldf Using VBScript
' This code sets the replication interval for a site link
strLinkName    = "<LinkName>"  ' cn of the link you want to configure
intNewInterval = <NewInterval> ' replication interval in minutes
' ------ END CONFIGURATION ---------

set objRootDSE = GetObject("LDAP://RootDSE")
set objLink = GetObject("LDAP://cn=" & strLinkName & _
                        ",cn=IP,cn=Inter-site Transports,cn=sites," & _
                        objRootDSE.Get("configurationNamingContext") )
objLink.Put "replInterval", intNewInterval
WScript.Echo "Set interval for link " & objLink.Get("cn") & _
             " to " & intNewInterval

12.6.3 Discussion

To configure the inter-site replication interval between two sites, you need to set the replInterval attribute on the site-link object that connects the two sites. The value of the attribute should be the replication interval in minutes. The default value is 180 minutes (3 hours) and the minimum is 15 minutes
