Figure 4-3. When you start an administrative tool as an ordinary user, you are prompted for the password of the user root. This is one way to change to root from a text-based console. In Open Enterprise Server, you ll find yourself working with the GUI most of the time. In this interface, it is also possible to run one program as the user root, and be logged in as any other user simultaneously. To do so, follow these steps. 1. Use the keys Alt+F2 from the KDE interface to open the Run Command window. 2. Click Options (see Figure 4-4) and select Run As A Different User. Specify the name and password of the user account you want to use. 3. Type the name of the program you d like to run. You will now have root access from this program only.

The Request Is Contained within Expression 1 condition type allows you to compare the REQUEST value against the multiple values specified in Expression 1. In the previous example of using the Request = Expression 1 condition, you modified the REQUEST value of the Go button to match the REQUEST value of the P1_REPORT_SEARCH text field so that you could compare a single REQUEST value. Using the Request Is Contained within Expression 1 condition type instead, you could simply use the two different REQUEST values, rather than needing to make the REQUEST values the same. If you change the REQUEST value of the Go button back to its original value of Go, you can modify the PL/SQL page process to use a condition like the one shown in Figure 4-18.

Figure 4-4. From the KDE graphical interface, you can use Alt+F2 to perform commands as another user.

Figure 4-18. Using the Request Is Contained within Expression 1 condition type Notice that this example uses a comma-separated list of values in Expression 1. However, the text in Expression 1 is actually evaluated using an INSTR test, so the REQUEST value is tested like this: INSTR(text in expression 1, value of REQUEST item) > 0 and the condition is effectively evaluated as this: INSTR('P1_REPORT_SEARCH,Go', :REQUEST) > 0 So it does not really matter which delimiter you use. You could use a colon, an exclamation point, or any other symbol, since the values contained in Expression 1 are not being parsed into their individual values. Instead, the entire text in Expression 1 is searched to see if the string containing the REQUEST value appears anywhere within it.

You can also switch your current user ID another way. From the Novell menu, select the option Switch User. This opens a new login screen in which you can authenticate as a different user for example, as the user root. This isn t recommended, however, because if you switch to a new session as user root, you ll again have root access to all system components, which is just what we wanted to avoid.

Summary

By default, your server starts with a graphical user interface. This is useful if you re new to Linux and don t like console-based interfaces, or if you want to work directly from the server console to manage your network. If, however, your server is in a locked-down server room and you rarely sit behind it to work on it, this graphical interface is merely a waste of valuable system resources. So why not change the way your server boots and let it boot each time with a consolebased interface To do this, you have to change the runlevel of your server.

You need to be very careful when using Contained within Expression conditions, because of the opportunities for false positive matches to be made. You could find that by using poor choices for your REQUEST values, you end up matching against a REQUEST value that you didn t intend to match against. As an example, imagine that you have two buttons on your page: a button used to submit the page, with a REQUEST value of Go, and another button that is used to log the user out of the application, with a REQUEST value of Goodbye. Suppose you want to run a PL/SQL process when the user clicks the logout button, and therefore use the condition shown in Figure 4-19. The problem with this is that when the user clicks the submit button, which has a REQUEST value of Go, the APEX engine will perform this evaluation: if instr('Goodbye', 'Go') > 0 then return true; else return false; end if;
