It s fairly easy to install RubyGems on Linux, and you can use the same procedure to install RubyGems on Mac OS X. On those systems, use the following shell commands to download and install RubyGems: curl -O http://rubyforge.org/frs/download.php/11289/rubygems-0.9.0.tgz tar -xvzf rubygems-0.9.0.tgz cd rubygems-0.9.0.tgz ruby setup.rb Once you ve done so, set an environment variable, RUBYOPT, using a line in your .profile: export RUBYOPT=rubygems This environment variable causes RubyGems to be run whenever Ruby is run. You can get an similar effect by including the line require "rubygems" in all of your Ruby scripts, but since most Ruby scripts using RubyGems are written assuming that you have RUBYOPT set, that ll require you to modify all of the programs you download no small task. You can also run your Ruby script with the -rubygems option, but that s a lot of extra typing.

Figure 7-2. Testing a connection Connections are a limited server resource. This means it s imperative that you open the connection as late as possible and release it as quickly as possible. In the previous code sample, an exception handler is used to make sure that even if an unhandled error occurs, the connection will be closed in the finally block. If you don t use this design and an unhandled exception occurs, the connection will remain open until the garbage collector disposes of the SqlConnection object. An alternate approach is to wrap your data access code in a using block. The using statement declares that you are using a disposable object for a short period of time. As soon as the using block ends, the CLR releases the corresponding object immediately by calling its Dispose() method. Interestingly, calling the Dispose() method of a Connection object is equivalent to calling Close(). That means you can rewrite the earlier example in the following, more compact, form: string connectionString = WebConfigurationManager.ConnectionStrings["Northwind"].ConnectionString; SqlConnection con = new SqlConnection(connectionString); using (con) { con.Open(); lblInfo.Text = "<b>Server Version:</b> " + con.ServerVersion; lblInfo.Text += "<br /><b>Connection Is:</b> " + con.State.ToString(); } lblInfo.Text += "<br /><b>Now Connection Is:</b> "; lblInfo.Text += con.State.ToString(); The best part is that you don t need to write a finally block the using statement releases the object you re using even if you exit the block as the result of an unhandled exception.

Acquiring a connection takes a short, but definite, amount of time. In a web application in which requests are being handled efficiently, connections will be opened and closed endlessly as new requests are processed. In this environment, the small overhead required to establish a connection can become significant and limit the scalability of the system. One solution is connection pooling. Connection pooling is the practice of keeping a permanent set of open database connections to be shared by sessions that use the same data source. This avoids the need to create and destroy connections all the time. Connection pools in ADO.NET are completely transparent to the programmer, and your data access code doesn t need to be altered. When a client requests a connection by calling Open(), it s served directly from the available pool, rather than re-created. When a client releases a connection by calling Close() or Dispose(), it s not discarded but returned to the pool to serve the next request. ADO.NET does not include a connection pooling mechanism. However, most ADO.NET providers implement some form of connection pooling. The SQL Server and Oracle data providers implement their own efficient connection pooling algorithms. These algorithms are implemented entirely in managed code and in contrast to some popular misconceptions do not use COM+ enterprises services. For a connection to be reused with SQL Server or Oracle, the connection string matches exactly. If it differs even slightly, a new connection will be created in a new pool.
