Namespace:  Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Rmo (in Microsoft.SqlServer.Rmo.dll)

Syntax

'Declaration
Public Property AgentCheckupInterval As Integer 
    Get 
    Set
'Usage
Dim instance As ReplicationServer 
Dim value As Integer 

value = instance.AgentCheckupInterval

instance.AgentCheckupInterval = value

public int AgentCheckupInterval { get; set; }

public:
property int AgentCheckupInterval {
    int get ();
    void set (int value);
}

member AgentCheckupInterval : int with get, set

function get AgentCheckupInterval () : int 
function set AgentCheckupInterval (value : int)

Property Value

Type: System.Int32
An Int32 value that specifies the interval for the distribution to perform a checkup.

Exceptions

Exception	Condition
ApplicationException	When the server is not a Distributor.

Remarks

Use IsDistributor to check whether or not the current server is a Distributor before you use AgentCheckupInterval.

The AgentCheckupInterval property can be retrieved by the public fixed database role.

The AgentCheckupInterval property can be set by the sysadmin fixed server role only. Getting the AgentCheckupInterval property is equivalent to executing the sp_helpdistributor_properties (Transact-SQL) stored procedure.

Examples

           // Set the Distributor and distribution database names.
            string distributionDbName = "distribution";
            string distributorName = publisherInstance;
