extern "C" __declspec(dllimport) double XYZGetData(HXYZ hxyz); The extern "C" linkage modifier is neither allowed nor necessary in P/Invoke functions In C++, it is used to ensure that global functions can be called from C code When generating a managed-to-unmanaged thunk from a P/Invoke function, the JIT compiler automatically looks for functions without mangled names in the target DLL You can replace the __declspec(dllimport) specification by applying the DllImportAttribute with the name of the target DLL to the P/Invoke function [DllImport("XYZLibdll")] .. function declaration goes here .. Key to enabling the features of SafeHandle is the replacement of the native handle type with XYZHandle^ a tracking handle to the SafeHandle-derived handle class To avoid naming conflicts with the global functions from the native API, the P/Invoke functions are defined as private static member functions of the native class: public ref class XYZConnection { [DllImport("XYZLibdll")] static XYZHandle^ XYZConnect(); [DllImport("XYZLib.

Some of the Data Pump Export utility parameters will be familiar to you from the traditional export utility. Others are quite new. Here, I ll briefly run through the parameters, providing detailed explanations for the most important parameters. For this discussion, I ve grouped the parameters into the following categories: File- and directory-related parameters Export mode-related parameters Export filtering parameters Estimation parameters The network link parameter Interactive mode export parameters Job-related parameters Note that you can use all the export parameters at the command line or in parameter files, except for those listed in the Interactive Mode Export Parameters section.

++ ps -ef ++ grep '[c]ron' ++ wc -l + cron_count=4 + '[' 4 -ne 5 ']' + echo 'Cron Count 4' + mail -s 'Cron Count 4' rbpeters

You can specify several file- and directory-related parameters during a Data Pump Export job. These include the DIRECTORY, DUMPFILE, FILESIZE, PARFILE, LOGFILE, NOLOGFILE, and COMPRESSION parameters.

The DIRECTORY parameter refers to the directory object to be used for dump files and log files. See the Using Directory Objects section earlier in this chapter for details.

Shell variables are variables whose values are set by the shell itself, instead of by a user. Shell variables are also called keyword variables, since short keywords are used to represent some of these variables. When you first log into a UNIX system, you must make several bits of information available to the shell, such as the name of your home directory, the type of editor you prefer to use for editing text, and the type of prompt you want the system to display while your session is active. Each of these is determined by values assigned to shell variables. These are some common shell variables: HOME: Identifies a user s home directory. PATH: Specifies the directories in which the shell should look when it tries to execute any command. It s common to include both the binary (bin) directories for UNIX and Oracle software as part of the PATH variable. Fortunately, you don t have to manually set up the environment every time you log into the system. There is a file, named .profile or .login, depending on the type of UNIX shell you are using, that automatically sets the environment variables for all users at login time. When you log in, the shell will look in the appropriate file and establish the environment by setting the values of all shell variables.
