You can see the issue here: rather than auditing that user jimb performed the action in the APEX application, it has been logged as being performed by the HTMLDB_PUBLIC_USER user. This is because HTMLDB_PUBLIC_USER is the user specified in the DAD. So, after all we ve said about not using a single account for logging in to the database, have we reached a roadblock in identifying which user performed the action in the APEX application Well, as you might have guessed, we wouldn t have brought you this far if it were not possible to find out which user performed the action. The answer lies in the client_id column. Fortunately, the Oracle team behind APEX had the foresight to populate the client_id for you: system@DBTEST> select db_user, client_id 2 from dba_fga_audit_trail; DB_USER CLIENT_ID -------------------- -----------------------------JIMB HTMLDB_PUBLIC_USER JIMB:2264954872210432 This is also an extremely good illustration of why it s important to instrument your code in the same way that the Oracle team has done by including the APEX session information in the client_id column. You never know when that information will be useful to someone else, and if you haven t made it possible for others to access that information, that lack could cause all sorts of unforeseen problems. The client_id column not only contains the name of the user (jimb) but also the session ID that was used (2264954872210432), so the format of the client_id value is user:session_id. Having this level of detail available to you from the audit log allows you to go back into the APEX instance management and drill down into the recent session information that matches the information from the client_id column, as shown in Figure 5-32. Then you can drill down into the session information, as shown in Figure 5-33.

To extend the schema, you need access to a server that has a writable replica. Make sure the server Tip

Summary

The sooner customers can start to use the software, the sooner the customers can receive a return on their investment. Projects that develop systems in small increments prove to be more successful than those that have long delivery dates.

If you are working on OES - NetWare and you don t like the NetWare console, some alternatives are available.

This chapter covered methods you can use to control the data your users can access and what actions they can perform on that data, while auditing the actions they perform. It s extremely important to consider using features such as VPD and auditing in the early stages of application design. Although you can easily enable functionality such as auditing using the DBMS_FGA package later on, trying to retrofit VPD into an application when you have already written additional predicates for all your queries is a much bigger and more daunting task. There is often resistance to changing things once they are working after all, who wants to risk being the one to break something that has worked for a long time This is why you should consider the options you have available to you at the early stages of project design. Investigate the latest database features to see what they can do for you. Many people have written their own auditing solutions when they could have saved a lot of development time by using the built-in database features instead.

The first alternative to using the NetWare console is the NSNSHELL. With NSNSHELL, you can open a DOS-like shell that offers more possibilities, especially regarding file management. The number of commands that can be used is limited, but that doesn t make the tool less useful. As an example, the following explains how to copy an NLM from a floppy disk to the directory SYS:SYSTEM on your server.

Take the time to think ahead when you re designing an application. Think about all the areas in which you can cut down on the amount of repetitive work you need to do. Using packages such as DBMS_RLS and DBMS_FGA means that you not have to reinvent the wheel to get the job done.

1. Use the command nsninit to initialize support for the Novell scripting environment. 2. Type nsnshell to start the Novell Script for NetWare shell environment. This is, in fact, a basic environment meaning that all scripts available are written in basic. 3. Use the command cd \Nsn\UTIL. Here, you ll find many basic scripts with the same names as your favorite DOS commands. 4. To copy the file NW5-IDLE.NLM from a diskette to the directory SYS:SYSTEM on your server, use the command copy a:\nw5-idle.nlm sys:\system\nw5-idle.nlm. Still not convinced that the NSNSHELL is useful Just start it and try some of the following programs. userlist: Displays a list of all current connections to your server. screen: Displays all active screens one after another in a loop. netmon: Shows a list of critical parameters on your server like activity in the file system and CPU utilization. phaser: No comments, just try it! wordgame: A word-guessing game that s included with your server software! (See Figure 5-8.)
