ReplicationDatabase.LogReaderAgentProcessSecurity Property

Gets the Microsoft Windows account under which the Log Reader Agent job runs at the Distributor.

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

public IProcessSecurityContext LogReaderAgentProcessSecurity { get; }

Property Value

Type: Microsoft.SqlServer.Replication.IProcessSecurityContext
An IProcessSecurityContext object that specifies the Windows account used by SQL Server Agent when running the Log Reader Agent.

ExceptionCondition
ApplicationException

When the Log Reader Agent job does not exist or the version of SQL Server is not SQL Server 2005 or later.

When the Queue Reader Agent has not been upgraded to the SQL Server 2005 replication agent security model. For more information, see Security and Protection (Replication).

For security reasons, Password is always masked in the return value.

The Windows account specified by the LogReaderAgentProcessSecurity property is always used by the Log Reader Agent when connecting locally to the Distributor. For information about the connections that agents make and the permissions that are required for those connections, see Replication Agent Security Model.

The LogReaderAgentProcessSecurity property can be retrieved by members of the sysadmin fixed server role or by members of the db_owner fixed database role of the published database.

Retrieving the LogReaderAgentProcessSecurity property is equivalent to executing sp_helplogreader_agent (Transact-SQL).

The LogReaderAgentProcessSecurity property is available with SQL Server 2005 only.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
