Of course, the Oracle home directory is only for the Oracle binaries. The DBA must also create separate database directories for locating the data files, control files, redo logs, and other files. The Oracle installer suggests a subdirectory of the Oracle base directory for locating these files. However, the system administrator must create separate directories for the database-related files. Ideally, these directories must be created on separate physical devices. This way, you can distribute physical I/O as well as have different devices for locating your duplexed control files and redo log files. Although same drive can be used for creating all the directories, it won t be possible to fully implement the OFA guidelines. Create multiple database directories using the following format (adjusted for your requirements), and make sure that the oracle user has write permissions on them: $ mkdir -p /prod10/oradata/prod $ chown -R oracle:oinstall /prod10/oradata/prod $ chmod -R 775 /prod10/oradata/prod

As I mentioned earlier in this chapter, Oracle strongly recommends that you maintain a flash recovery area for storing all recovery-related files. You must place the recovery files on a different physical disk from the database files, to prevent a disk failure from affecting both the current database files and the recovery files. Here s an example showing how to create and set the appropriate owner, group, and permissions on the directory for the flash recovery area. I named the subdirectory flash_recovery_area, but it could be anything that you specify using the DB_RECOVERY_FILE_DEST parameter: $ mkdir -p /prod20/oradata/prod/flash_recovery_area $ chown -R oracle:oinstall /prod20/oradata/prod/flash_recovery_area $ chmod -R 775 /prod20/oradata/prod/flash_recovery_area

As was mentioned in the Creating the Oracle User section, the system administrator must create an account for the owner of the Oracle software. Usually, this is an account with the name oracle. The Oracle owner in our case, the oracle user needs to set the environment variables before the installation of the software.

tar cvfz /mnt/nfs/wholedisk.tar.gz / --exclude /proc/* \ --exclude /mnt/nfs/*

You need to log in as the oracle user and set a number of environment variables. Although all of the environment variables can be set manually, you are better off editing the default shell startup file, which, on my Red Hat Linux server is the .bash_profile file in the home directory of the oracle user (the /home/oracle directory by default). By editing the shell startup file, you will ensure that the environment will always be set appropriately each time you log in. Here are the main environment variables that you need to set: ORACLE_BASE: The ORACLE_BASE variable is the starting directory for all Oracle installations. All the software files and other files are placed in directories underneath the ORACLE_BASE directory. In our example, the directory is /u01/app/oracle. ORACLE_HOME: When you re installing the Oracle server, the ORACLE_HOME variable should be set to oracle_base/product/10.2.0/db_1. In our case, this will be /u01/app/oracle/product/ 10.2.0/db_1. The Oracle installer prompts you for the value of the ORACLE_HOME variable during the installation of the software.

Your environment variables may be slightly different from the ones listed here, depending on your operating system and its version. Always check the operating system specific installation guides it s well worth the effort to read them. The specifics in this chapter are based on a Red Hat Linux operating system.

You can identify existing ORACLE_HOME directories by looking at the contents of the oratab file:

If you compile to managed code, string literals like "abc" and L"abc" can be either native or managed string literals The compiler determines this depending on the context In most cases, the context is obvious For example, if you pass a string literal to printf, it is unambiguous that it should be a native string literal, and if you call Console::WriteLine passing a string literal, it should obviously be a managed string literal If it is not obvious, the compiler will choose the managed string literal When a native string literal is used in managed code, the compiler generates a managed wrapper type that is similar to the wrapper types defined for native classes and structures In the code shown here, an ANSI code string literal and a Unicode string literal are used: // UsingNativeStringLiteralscpp // cl /clr usingNativeStringLiteralscpp #include <stdio.

If the oratab file exists, it contains lines similar to the following:
