This chapter contains the following topics: 1. Before You Start: Planning Your Installation. This section provides a list of tasks that Oracle recommends you complete before starting Oracle Clusterware and Oracle RAC installation. Whether your location is a Tier IV data center with a large project team of system administrators, storage administrators, network administrators, database administrators, and third- party hardware and software vendors, or you are a project team of one, planning is important to help ensure that your installation proceeds smoothly. It is beyond the scope of this documentation set to advise how to determine hardware sizing or capacity planning for your installation. Note that with Oracle Clusterware and Oracle RAC, you can add nodes and instances as needed in response to testing, or in response to increased workloads. Review and complete the following steps as part of your installation plan: 1. Check My Oracle Support. Before you decide whether you want to install Oracle Database 1. My Oracle Support: https: //support. Click the Certify tab. Check the Certification Matrix for Oracle RAC for the operating system platform on which you intend to install, to ensure that your hardware configuration is supported for use with Oracle Clusterware and Oracle RAC. How can I access Oracle from Python? I have downloaded a cx. I get the following error: import cx Guide: Installing Oracle Enterprise Manager 10g Grid Control Rel 5 on Oracle Database 11g and Linux by Mike Revitt. 1.1.1 Check My Oracle Support. Before you decide whether you want to install Oracle Database 11 g release 2 (11.2) on existing hardware, or decide what server and.
You can receive guidance about supported hardware options that can assist you with your purchasing decisions. To access to the Certification Matrix: Log on to My Oracle Support. Click the Certifications tab. Provide information about your platform to obtain certification information. In addition to specific certified hardware configurations, the Certify page provides support and patch information, and general advice about how to proceed with an Oracle Clusterware or Oracle Clusterware with Oracle RAC 1. Contact your Oracle Sales Representative if you do not have a My Oracle Support account. Also, you may want to refer to Oracle. In particular, refer to the Oracle Real Application Clusters pages on the Oracle Technology Network: http: //www. The Oracle RAC Technologies Certification Matrix provides details about supported technology that you can use to deploy Oracle RAC. Consider Using Software Updates Option. OUI can install critical patch updates, system requirement updates for supported operating systems, and other significant updates that can ensure that your installation succeeds. Oracle recommends that you enable the Software Updates option during installation. If you choose to enable the Software Updates option, then you must provide a valid My Oracle Support user name and password, so that OUI can download the latest updates, or you must provide a path to the location of a Software Updates option package that you have downloaded previously. In addition, if you have a proxy realm, then be prepared to provide the destination proxy realm, and the user authentication (user name and password) required to authenticate access through that realm to the Internet, so that OUI can obtain software updates. Check with your network administrator before installation if you do not have this information. If you plan to run the installation in a secured data center, then you can download updates before starting the installation by starting OUI on a system that has Internet access. To start OUI to download updates only, enter the following command. Installer - download. Updates. Provide the My Oracle Support user name and password, and provide proxy settings if needed. After you download updates, transfer the update file to a directory on the server where you plan to run the installation. Check Oracle Technology Network. The Oracle Technology Network (OTN) contains white papers about deployment options, capacity planning, best practices on various NFS platforms, and extended clusters deployments, which are not addressed in this guide. You can review available papers at the following Web site: http: //www. Review Installation Steps for Oracle RACInstalling Oracle RAC consists of the following steps: Prepare servers (system, storage, and network administration): Install the operating system and install the operating system packages and patches to the required version. Create the required groups, users, and software homes. Set up the domain name forwarding for Grid Naming Service (GNS) if you plan to deploy GNS, and set up the network addresses in the DNS and on the server as needed. Set up the required storage.(optional) Stage all of the software on one node for installation (the . This feature is called Redundant Interconnect Usage. Oracle RAC and Oracle ASM instances use these interconnect addresses to ensure highly available, load- balanced interconnect communication between nodes. Install Oracle Grid Infrastructure for a cluster, which includes Oracle Clusterware and Oracle Automatic Storage Management (system and storage administration): Install Oracle Grid Infrastructure for a cluster. During installation, Fixup scripts perform additional configuration of operating system parameters, secure shell (SSH) for installation and user environment variables. Patch Oracle Clusterware and Oracle Automatic Storage Management to the latest patchset. Install Oracle RAC (database administration): Install Oracle Real Application Clusters. Patch Oracle RAC to the latest patchset. Complete the postinstallation configuration of the Oracle RAC database. Review How to Use Cluster Verification Utility (CVU)Before installing Oracle Clusterware or Oracle RAC, use CVU to ensure that your cluster is prepared for an installation. CVU is incorporated into Oracle Universal Installer, so CVU runs when you start an Oracle RAC installation. However, you can use CVU to ensure that any packages or configuration information that is required for Oracle RAC are in place before you begin your Oracle RAC installation. Oracle provides CVU to perform system checks in preparation for an installation, patch updates, or other system changes. In addition, CVU can generate fixup scripts, which are scripts run by the root user that can change many kernel parameters to at least the minimum settings required for a successful installation. Using CVU can help system administrators, storage administrators, and database administrators to ensure that everyone has completed the system configuration and preinstallation steps, so that installations, updates, or patches complete successfully. You can obtain the latest version of CVU at the following URL: http: //www. Database administrators should refer to the section . Review the Oracle upgrade documentation before proceeding with installation, to decide how you want to proceed. Oracle RAC 1. 1g release 2 (1. Oracle Clusterware and Oracle ASM 1. The Oracle Clusterware release version must be equal to or greater than the Oracle RAC version that you want to install. For late- breaking updates and best practices about pre- upgrade, post- upgrade, compatibility, and interoperability discussions, refer to . The Oracle Clusterware version must be the most recent release of any software (Oracle Clusterware, Oracle Database, Oracle RAC and Oracle Automatic Storage Management) running on the cluster. You can have multiple Oracle homes of Oracle Databases on your cluster. However, the Oracle RAC database software in these homes must be from a version that is equal to or prior to the version of Oracle Clusterware that is installed; you cannot have a version of Oracle Database running on Oracle Clusterware that was released after the version of Oracle Clusterware that you are running. For example: If you have Oracle Clusterware 1. Oracle Database 1. Oracle RAC 1. 0g release 1, release 2, and Oracle RAC 1. However, you cannot have Oracle Clusterware 1. Oracle RAC 1. 1g. Starting with release 1. Database Upgrade Assistant (DBUA) for patch set upgrades with Oracle RAC. You can also use DBUA to upgrade between major point releases of Oracle RAC (for example, from 1. You cannot change the owner of the Oracle Database home during an upgrade. You must use the same Oracle software owner that owns the existing Oracle Database home. As with any system change, back up your existing database before installing new software. Review Globalization Requirements. Before you start an installation on which you want to support languages other than English, review Oracle Database Globalization Support Guide. Note the following: Oracle recommends that you use Unicode AL3. UTF8 as the database character set. Unicode is the universal character set that supports most of the currently spoken languages. Unicode also supports many historical scripts (alphabets). Unicode is the native encoding of many technologies, including Java, XML, XHTML, ECMAScript, and LDAP. Unicode is ideally suited for databases that support the Internet and the global economy. The locale setting of your operating system session determines the language of the user interface and the globalization behavior for components such as Oracle Universal Installer, Oracle Net Configuration Assistant, and Database Configuration Assistant. The locale setting also determines the globalization behavior of Oracle Database sessions created by a user application through Oracle JDBC driver, unless overridden by the application. The NLS. This variable also sets the language and territory used by the client application and the database. The variable also declares the character set for entering and displaying data by the client application. Command- line interface - Wikipedia. A command- line user interface (CLI), also known as a console user interface. A program which handles the interface is called a command language interpreter or shell. The CLI was the primary means of interaction with most computer systems until the introduction of the video display terminal in the mid- 1. Open. VMS, Unix systems and personal computer systems including MS- DOS, CP/M and Apple DOS. The interface is usually implemented with a command line shell, which is a program that accepts commands as text input and converts commands into appropriate operating system functions. Command- line interfaces to computer operating systems are less widely used by casual computer users, who favor graphical user interfaces or menu- driven interaction. Alternatives to the command line include, but are not limited to text user interfacemenus (see IBM AIX SMIT for example), keyboard shortcuts, and various other desktop metaphors centered on the pointer (usually controlled with a mouse). Examples of this include the Windows versions 1, 2, 3, 3. OS shell that runs in DOS), Dos. Shell, and Mouse Systems Power. Panel. Command- line interfaces are often preferred by more advanced computer users, as they often provide a more concise and powerful means to control a program or operating system. Programs with command- line interfaces are generally easier to automate via scripting. Command line interfaces for software other than operating systems include a number of programming languages such as Tcl/Tk, PHP and others, as well as utilities such as the compression utilities Win. Zip and Ultimate. Zip, and some FTP and ssh/telnet clients. Advantages. Under most operating systems, it is possible to replace the default shell program with alternatives; examples include 4. DOS for DOS, 4. OS2 for OS/2, and 4. NT or Take Command for Windows. Although the term 'shell' is often used to describe a command- line interpreter, strictly speaking a 'shell' can be any program that constitutes the user- interface, including fully graphically oriented ones. For example, the default Windows GUI is a shell program named EXPLORER. EXE, as defined in the SHELL=EXPLORER. EXE line in the WIN. INI configuration file. These programs are shells, but not CLIs. Application command- line interfaces. When a program is launched from an OS command line shell, additional text provided along with the program name is passed to the launched program. Interactive command line sessions: After launch, a program may provide an operator with an independent means to enter commands in the form of text. OS inter- process communication: Most operating systems support means of inter- process communication (for example; standard streams or named pipes). Command lines from client processes may be redirected to a CLI program by one of these methods. CLI software. Some examples of CLI- only applications are: Hybrid software. In some cases, a GUI is simply a wrapper around a separate CLI executable file. In other cases, a program may provide a CLI as an optional alternative to its GUI. CLIs and GUIs often support different functionality. For example, all features of MATLAB, a numerical analysis computer program, are available via the CLI, whereas the MATLAB GUI exposes only a subset of features. The early Sierra games, like the first three King's Quest games (1. History. Early computer systems often used teleprinter machines as the means of interaction with a human operator. The computer became one end of the human- to- human teleprinter model. So instead of a human communicating with another human over a teleprinter, a human communicated with a computer. In time, the actual mechanical teleprinter was replaced by a . These were typically used to interface an organization's new PC's with their existing mini- or mainframe computers, or to connect PC to PC. Some of these PCs were running Bulletin Board System software. Early operating system CLIs were implemented as part of resident monitor programs, and could not easily be replaced. The concept of implementing the shell as a replaceable component is usually attributed to Multics. Throughout the 1. Apple Macintosh and Microsoft Windows—command line interfaces were replaced in popular usage by the Graphical User Interface. The command line remains in use, however, by system administrators and other advanced users for system administration, computer programming, and batch processing. In November 2. 00. Microsoft released version 1. Windows Power. Shell (formerly codenamed Monad), which combined features of traditional Unix shells with their proprietary object- oriented . NET Framework. Min. GW and Cygwin are open- source packages for Windows that offer a Unix- like CLI. Microsoft provides MKS Inc.'s ksh implementation MKS Korn shell for Windows through their Services for UNIX add- on. Since 2. 00. 1, the Macintosh operating system is based on a variation of Unix called Darwin. On these computers, users can access a Unix- like command- line interface called Terminal found in the Applications Utilities folder. This terminal uses bash by default. This is typically the case with operating system command shells. CLIs are also used by systems with insufficient resources to support a graphical user interface. Some computer language systems (such as Python, Forth, LISP, Rexx, and many dialects of BASIC) provide an interactive command- line mode to allow for rapid evaluation of code. CLIs are often used by programmers and system administrators, in engineering and scientific environments, and by technically advanced personal computer users. CLIs are also popular among people with visual disability, since the commands and responses can be displayed using Refreshable Braille displays. Anatomy of a shell CLI. Commands are usually one of three classes. Internal — recognized and processed by the command line interpreter itself and not dependent upon any external executable file. Included — A separate executable file generally considered part of the operating environment and always included with the OS. External — External executable files not part of the basic OS, but added by other parties for specific purposes and applications. N — Optional parameters provided by the client. The format and meaning of the parameters depends upon the command issued. In the case of Included or External commands, the values of the parameters are delivered to the program (specified by the Command) as it is launched by the OS. Parameters may be either Arguments or Options. In this example, the delimiters between command line elements are whitespace characters and the end- of- line delimiter is the newline delimiter. This is a widely used (but not universal) convention for command- line interfaces. A CLI can generally be considered as consisting of syntax and semantics. The syntax is the grammar that all commands must follow. In the case of operating systems (OS), MS- DOS and Unix each define their own set of rules that all commands must follow. In the case of embedded systems, each vendor, such as Nortel, Juniper Networks or Cisco Systems, defines their own proprietary set of rules that all commands within their CLI conform to. These rules also dictate how a user navigates through the system of commands. The semantics define what sort of operations are possible, on what sort of data these operations can be performed, and how the grammar represents these operations and data—the symbolic meaning in the syntax. Two different CLIs may agree on either syntax or semantics, but it is only when they agree on both that they can be considered sufficiently similar to allow users to use both CLIs without needing to learn anything, as well as to enable re- use of scripts. A simple CLI will display a prompt, accept a . Advanced CLIs will validate, interpret and parameter- expand the command line before executing the specified command, and optionally capture or redirect its output. Unlike a button or menu item in a GUI, a command line is typically self- documenting, stating exactly what the user wants done. In addition, command lines usually include many defaults that can be changed to customize the results. Useful command lines can be saved by assigning a character string or alias to represent the full command, or several commands can be grouped to perform a more complex sequence – for instance, compile the program, install it, and run it — creating a single entity, called a command procedure or script which itself can be treated as a command. These advantages mean that a user must figure out a complex command or series of commands only once, because they can be saved, to be used again. The commands given to a CLI shell are often in one of the following forms: do. Something how to. Filesdo. Something how source. File destination. Filedo. Something how < input. File > output. Filedo. Something how . The > in the third example is a redirection operator, telling the command- line interpreter to send the output of the command not to its own standard output (the screen) but to the named file. This will overwrite the file. Using > > will redirect the output and append it to the file. Another redirection operator is the vertical bar (. Under Unix, commands also need be marked as executable files. The directories in the path variable are searched in the order they are given. By re- ordering the path, one can run e. Renaming of the executables also works: people often rename their favourite editor to EDIT, for example. The command line allows one to restrict available commands, such as access to advanced internal commands. The Windows CMD. EXE does this. Often, shareware programs will limit the range of commands, including printing a command 'your administrator has disabled running batch files' from the prompt. Some CLIs, such as those in network routers, have a hierarchy of modes, with a different set of commands supported in each mode. The set of commands are grouped by association with security, system, interface, etc.
