Generally timeout issue occurs because of the compatibility when an application uses Microsoft .net framework 3.5 or 4 data provider (sql client) to connect to the mirrored database.

Note: If ConnectionTimeout property is assigned a value of 15 seconds, user may receive error after connection is open for 1.2 seconds.

The timeout of the SQL ‘statement’ is set to 30 s by default. Timeout property is of the SQLCommand object. User can set property according to their requirements:

using (SqlCommand myCommand = new SqlCommand())

{

// Set the new command timeout to 60 seconds

// in stead of the default 30

myCommand.CommandTimeout = 60;

}
