EMS SQL Manager for SQL Server

On-line Documentation

Connection settings


The Connections section of the Server Properties dialog allows you to configure the instance of Microsoft® SQL Server by setting options pertaining to connection in groups: Connections, Remote server connections.

 

Connections

 

Maximum number of concurrent connections

If this option is set to a value other than zero, the number of connections that SQL Server will allow is limited. The default value is 0 (unlimited).

 

Server Properties - Connections

 

 

Default connection options

Specifies the default connection options as described in the table below:

 

Configuration option

 

Description

 

CheckBox Disable deferred constraint checking

 

Controls interim or deferred constraint checking.

CheckBox Implicit transactions

 

Controls whether a transaction is started implicitly when a statement is run.

CheckBox Cursor close on COMMIT

 

Controls behavior of cursors after a commit operation has been performed.

CheckBox ANSI warnings

 

Controls truncation and NULL in aggregate warnings.

CheckBox ANSI padding

 

Controls padding of fixed-length variables.

CheckBox ANSI NULLs

 

Controls NULL handling when using equality operators.

CheckBox Arithmetic abort

 

Terminates a query when an overflow or divide-by-zero error occurs during query execution.

CheckBox Arithmetic ignore

 

Returns NULL when an overflow or divide-by-zero error occurs during a query.

CheckBox Quoted identifier

 

Differentiates between single and double quotation marks when evaluating an expression.

CheckBox No count

Turns off the message returned at the end of each statement that states how many rows were affected.

 

CheckBox ANSI NULL default on

Alters the session's behavior to use ANSI compatibility for nullability. New columns defined without explicit nullability are defined to allow nulls.

 

CheckBox ANSI NULL default off

Alters the session's behavior not to use ANSI compatibility for nullability. New columns defined without explicit nullability are defined not to allow nulls.

 

CheckBox Concat NULL yields NULL

 

Returns NULL when concatenating a NULL value with a string.

CheckBox Numeric round abort

 

Generates an error when a loss of precision occurs in an expression.

CheckBox Xact abort

Rolls back a transaction if a Transact-SQL statement raises a run-time error.

 

 

Remote Server Connections

 

CheckBox Allow remote connections to this server

Controls the execution of stored procedures from remote servers running instances of SQL Server. Selecting this check box has the same effect as setting the sp_configureremote access option to 1. Clearing it prevents execution of stored procedures from a remote server.

 

Remote query timeout (in seconds, 0 = no timeout)

Specifies how long (in seconds) a remote operation may take before SQL Server times out. The default is 600 seconds, or a 10-minute wait.

 

CheckBox Require distributed transactions for server-to-server communication

Protects the actions of a server-to-server procedure through a Microsoft® Distributed Transaction Coordinator (MS DTC) transaction.
