As each site can have its own prefix, and you can import many prefixed versions of Drupal s tables into one database, this is the solution if you have only one database available from your hosting company. The $db_prefix variable is more flexible, however, and can alternatively take an array of prefixes and table names. This makes a whole different set of configurations possible. For example, the Location module (discussed in 4) comes with a zipcodes table that is quite large and is read-only. Drupal never writes data to this table; it uses the table only to look up locations. It would be redundant and wasteful to import this table for every Drupal site that you run, so an elegant solution is to have all of your Drupal installations share it. You can achieve this through use of the $db_prefix variable. When using the array syntax for $db_prefix, the keys are the names of tables and the values are the prefixes: $db_prefix = array( 'table_name1' => 'prefix1', 'table_name2' => 'prefix2', [...] ); The key default defines the default prefix that will be used for every table whose prefix isn t explicitly defined in the array. These two definitions are equal: $db_prefix = 'demo_'; $db_prefix = array('default' => 'demo_'); Now when you install the Location module, you can use the prefix.sh script to add a prefix to the zipcodes database table. This makes configurations like those shown in Listings 6-1 and 6-2 possible, where two different sites share a common table. Listing 6-1. Sharing the Zipcodes Table, Site 1 $db_prefix = array( 'default' => 'site1_', 'zipcodes' => 'shared_' ); Listing 6-2. Sharing the Zipcodes Table, Site 2 $db_prefix = array( 'default' => 'site2_', 'zipcodes' => 'shared_' ); Using this configuration, you can have two sites in the same database, each with its own separate and independent tables, with the exception of the zipcodes table, which is shared. This is a very useful approach, and the next sections offer two more suggestions for interesting opportunities to share tables.

One important note about this process is that this installer package relies on scripts and executables that must run under the host operating system. If you use a product that installs packages while netbooted, this type of installer will require you to postpone this installation. This can be accomplished in tools like DeployStudio using the postpone installation checkbox or a reboot policy in Jamf s Casper suite. If you fail to do this, you may find your package installation does not complete correctly or, in the worst-case scenario, may stall your whole imaging process. If you are relying on the Apple Tools for imaging, you may want to create a self-destructing startup item that runs the installer command. More information about this procedure can be found in 8.

The RemotingConfiguration class as its name says is the primary class for configuring .NET Remoting applications. You can use the class for registering your types either manually or through configuration files. This class cannot be used for registering channels; in that case, you have to use the ChannelServices class, which will be explained later in this appendix. Usage examples: // configure an object published on the server as a Singleton RemotingConfiguration.RegisterWellKnownServiceType( typeof(CustomerManager), "CustomerManager.soap", WellKnownObjectMode.Singleton); // configure a remote object on the client residing under the following URL RemotingConfiguration.RegisterWellKnownClientType( typeof(IRemoteComponent), "tcp://localhost:8080/MyRemote.rem"); // perform the configuration based on the contents of MyConfigFile.config RemotingConfiguration.Configure("MyConfigFile.config");

Enlisting a port enables a subscription in the BizTalk MessageBox. If a send port is not enlisted, a message published to the MessageBox will not be subscribed to by the send port. If a subscriber is not found (the message had only the send port as the intended subscriber), a BizTalk error would be thrown, indicating that a matching subscription could not be found, and the message instance would be suspended but resumable in the MessageBox. (In previous versions of the product, this would have caused the message instance to be suspended but not resumable.) If a message is published to the BizTalk MessageBox and a send port is not started, the message instance will sit in the MessageBox, waiting for the subscribing send port to be started. This situation is often hard to troubleshoot, as no error is thrown during the message submission process (an administrator would need to proactively look at what processes have been suspended using the Group Hub page). In addition to administering send ports via the product tool set, BizTalk also has an object model available to allow programmatic administration via Windows Management Instrumentation (WMI). Send port administration is accessible via the base class Microsoft.BizTalk.ExplorerOM.SendPort. Within this class, a send port has a variety of methods available (for example, ChangeSendPortStatus()). Refer to the BizTalk product documentation for an inclusive list.
