Applies to: SQL Server
Sets server options for remote servers and linked servers.
sp_serveroption [ @server = ] N'server' , [ @optname = ] 'optname' , [ @optvalue = ] N'optvalue' [ ; ]
[ @server = ] N'server'
The name of the server for which to set the option. @server is sysname, with no default.
[ @optname = ] 'optname'
The option to set for the specified server. @optname is varchar(35), with no default. @optname can be any of the following values.
|collation compatible||Affects distributed query execution against linked servers. If this option is set to
This option should be set only if it is certain that the data source corresponding to the linked server has the same character set and sort order as the local server.
|collation name||Specifies the name of the collation used by the remote data source if use remote collation is
Use this option when accessing an OLE DB data source other than SQL Server, but whose collation matches one of the SQL Server collations.
The linked server must support a single collation to be used for all columns in that server. Don't set this option if the linked server supports multiple collations within a single data source, or if the linked server's collation can't be determined to match one of the SQL Server collations.
|connect timeout||Specifies the timeout value in seconds for connecting to a linked server.
You can view this setting from the
|data access||Enables and disables a linked server for distributed query access. Can be used only for
|name||Specifies the name of the linked server object.
The name change is reflected in the value returned by the
|provider string||Specifies the OLE DB string that identifies the source of a linked server connection.
The provider string change is reflected in the value returned by the
|lazy schema validation||Determines whether the schema of remote tables is checked.
|query timeout||Specifies the timeout value for queries against a linked server.
|rpc||Enables RPC from the given server.|
|rpc out||Enables RPC to the given server.|
|system||Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.|
|use remote collation||Determines whether the collation of a remote column or of a local server is used.
|remote proc transaction promotion||Use this option to protect the actions of a server-to-server procedure through a Microsoft Distributed Transaction Coordinator (MS DTC) transaction. When this option is
After a Transact-SQL distributed transaction has been started, remote stored procedure calls can be made to other instances of SQL Server that have been defined as linked servers. The linked servers are all enlisted in the Transact-SQL distributed transaction, and MS DTC ensures that the transaction is completed against each linked server.
If this option is set to
If before making a server-to-server procedure call, the transaction is already a distributed transaction, then this option has no effect. The procedure call against linked server runs under the same distributed transaction.
If there's no transaction active in the connection before making a server-to-server procedure call, this option has no effect. The procedure then runs against linked server without active transactions.
The default value for this option is
[ @optvalue = ] N'optvalue'
Specifies whether the @optname should be enabled (
on), or disabled (
off). @optvalue is nvarchar(128), with no default.
For the connect timeout and query timeout options, @optvalue may be a non-negative integer.
For the collation name option, @optvalue may be a collation name or
For the name option, @optvalue may be a string, which represents the new name of the linked server connection.
For the provider string option, @optvalue may be a string or
NULL, representing the new OLE DB source of the linked server connection.

Requires ALTER ANY LINKED SERVER permission on the server.
The following example configures a linked server corresponding to another instance of SQL Server,
SEATTLE3, to be collation compatible with the local instance of SQL Server.
USE master; GO EXEC sp_serveroption N'SEATTLE3', 'collation compatible', N'true'; GO
The following example renames the linked server connection from
USE master; GO EXEC sp_serveroption @server = N'PRODVM01\ProdSQL01', @optname = 'name', @optvalue = N'LinkToProdSQL01'; GO
