If the current cputime is greater than the error threshold, we call the notify() function with a different set of options.

Since assemblies built with /clr:pure do not have native code, dependent DLLs are loaded differently. This difference is another aspect that must be considered when choosing a compilation model. To get some more information about this difference, consider the following simple application: // DependentDLLs.cpp // compile with "CL /clr DependentDLLs.cpp" // or with "CL /clr:pure DependentDLLs.cpp" // by including windows.h, the function Beep is declared #include <windows.h> // this line adds kernel32.lib (the import lib for kernel32.dll) // the list of linker inputs #pragma comment(lib, "kernel32.lib") int main() { Beep(440, 100); } If you compile this file to native code or choose the compilation model /clr, DLLs like kernel32.dll end up as load-time dependencies of the application. You can easily inspect this using the command-line option /imports from the tool dumpbin.exe. For the application compiled with /clr, the dumpbin output is as follows:

The UTL_MAIL package enables you to send and receive e-mail, along with attachments, CC, BCC, and return receipt features. Unlike most of the other packages in this chapter, you ll have to configure a couple things before you can use it. First, you must install the UTL_MAIL package in your database, as shown here: SQL> CONNECT sys/sys_passwd SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql SQL> @$ORACLE_HOME/rdbms/admin/prvtmail.sql After you install the package, you must define the SMTP_OUT_SERVER parameter in your init.ora initialization file or the SPFILE (if you re using it), as shown here: SQL> ALTER SYSTEM SET smtp_out_server='my.domain.com' SCOPE=SPFILE;

If you don t specify a value for the SMTP_OUT_SERVER parameter, then the SMTP server name defaults to the value of DB_DOMAIN and the port number defaults to 25.

Because the SMTP_OUT_SERVER parameter isn t a dynamically modifiable parameter, you must restart the database at this point to use the SMTP server. Here s an example that shows how to send an e-mail using the UTL_MAIL package: SQL> BEGIN UTL_MAIL.send(sender recipients cc bcc subject message END; / SQL> => => => => => => 'salapati@netbsa.org', 'samalapati@yahoo.com', 'shannonalapati@yahoo.com', 'salapati@hotmail.com', 'Testing the UTL_MAIL Package', 'If you get this, UTL_MAIL package really works!');

In 14, you learned how to transport tablespaces across different platforms. The new DBMS_TDB package tells you whether you can use the CONVERT TABLESPACE command in RMAN to transport tablespaces across platforms, when the endian formats of the two operating system platforms aren t the same. In addition to checking the endian formats, the packages also verify that other preconditions to transporting tablespaces, such as keeping the tablespaces open and in the read-only mode, are satisfied. You must execute the DBMS_TDB package prior to transporting a tablespace, to ensure you meet all the necessary conditions for transporting the tablespace to a different platform. The DBMS_TDB package consists of two functions, CHECK_DB and CHECK_EXTERNAL. I explain both of these briefly next.
