remote query timeout Option
Use the remote query timeout option to specify how long, in seconds, a remote operation can take before Microsoft SQL Server times out. The default is 600, which allows a 10-minute wait. This value applies to an outgoing connection initiated by the Database Engine as a remote query. This value has no effect on queries received by the Database Engine.
For heterogeneous queries, remote query timeout specifies the number of seconds (initialized in the command object using the DBPROP_COMMANDTIMEOUT rowset property) that a remote provider should wait for result sets before the query times out. This value is also used to set DBPROP_GENERALTIMEOUT if supported by the remote provider. This will cause any other operations to time out after the specified number of seconds.
For remote stored procedures, remote query timeout specifies the number of seconds that must elapse after sending a remote EXECstatement before the remote stored procedure times out.
The setting takes effect immediately without a server stop and restart.
