for anything from fixing a stove in a house to repairing assembly-line equipment in a plant. In the future, we will be able to support unantici pated information needs by making information accessible from mobile devices. We will also be able to access dynamic information such as inven tory levels in real-time. Just imagine the benefits that can be gained if a technician has access to the information that most companies have stored in their internal system (their intranet). If some spare parts are needed for the next job, technicians can simply order them from their mobile device. That way, a task can be completed when they leave a client location. An increasing number of companies are connecting their production units directly to IT systems. This enables them to monitor processes in realtime, which increases efficiency because they know if something is going wrong or if spare parts are needed. In this way, technicians can have direct access to the same information while standing next to the equipment; they will be connected wirelessly to both the machine in question and the IT systems in the back-office. Providing technicians with access to manuals, the spare-parts inventory, and documentation of recent repairs carried out by other people will definitely increase their efficiency. When discussing field service, we normally imply mobile employees outside the plant, but we will see that many benefits come from employees connected wirelessly inside the plant as well. Let s look at the standard field service process: Identify Plan Perform Report Follow up First, there has to be a service need, which is normally handled by some kind of dispatching function. The information is registered in the adminis trative system, and then the dispatcher assigns someone to the task.

By default, the %1 and %2 placeholders display the values in bytes. You can also set a conversion value by which the values are divided. To accomplish this, assign a numeric value to the conversion property. For example, if you want %1 and %2 to display kilobytes instead of bytes, set conversion to 1,024 (there are 1,024 bytes in a kilobyte).

On the next page you can select the default character set used in your database The Standard Character Set option is selected for this example (see Figure 114), but oftentimes this is not the best option because it does not allow the most compatibility with existing systems or allow for expansion over time For this example it will work just fine because you will not have any advanced characters being used You can, of course, select any option that best fits your usage, but I prefer the Best Support for Multilingualism option This option allows for greater expansion and is highly recommended when storing text in many different languages Select the Manual Selected Default Character Set/Collection option for the rare times when you want to specify a certain character set to use rather than choosing a selection of them.
