Workgroup 2000

Oracle announced the Workgroup/2000 suite of integrated client/server tools in January, 1995. The available product list in the Oracle Workgroup/2000 suite is growing. Information about the Oracle Workgroup/2000 suite is available on the Oracle World Wide Web server. Currently, you can download the 90-day free trial software from the Oracle World Wide Web server at http://www.oracle.com.

This chapter gives an overview of what is included in the Oracle Workgroup/2000 suite, the system requirements for Oracle Workgroup Server, and the differences among Oracle Workgroup Server and other Oracle packages. This chapter concentrates on the Oracle7 Workgroup Server, which is part of the Oracle Workgroup/2000 suite. It also discusses what tools and utilities are included and their major components. This chapter explains when it is appropriate to use the Oracle Workgroup Server and how it meets your business and technical needs.

Overview of the Oracle Workgroup/2000 Suite

The Oracle Workgroup/2000 suite is targeted for the workgroup client/server environment in which the users and developers have easy access and control of their database with integrated graphical tools and utilities. The following products are part of the Oracle Workgroup/2000 suite:

Personal Oracle7 is presented in Chapter 56, "Personal Oracle7," Oracle Objects for OLE is discussed in detail in Part IX of this book, and Part VIII gives an in-depth look at Oracle Power Objects. This section gives an overview of the Oracle7 Workgroup Server.

How Oracle7 Workgroup Server Differs From Other Oracle Packages

The Oracle7 server supports large-scale and distributed database environments, whereas the Oracle7 Workgroup Server is designed for small to medium-sized workgroups that require powerful client/server solutions with the advantages of easy installation, ease-of-use, and simplified database administration and management. The Oracle7 Workgroup Server is a full-functioning, multiuser Oracle7 server. It is designed to meet the needs of workgroups to access data within a personal computer local area network environment.

Certain Oracle7 features are currently not available in the Oracle7 Workgroup Server version 7.1, such as the distributed options, data replication, two-phase commit, parallel options, symmetric data replication, and the parallel server option. Some of them are not implemented in the Oracle7 Workgroup Server because most of the independent workgroups do not require real-time access to the data from their distributed databases.

The Oracle7 Workgroup Server is based on the Oracle7 architecture. It is completely scaleable because it shares the same Oracle7 code base as the Oracle7 Server that runs on over 80 different hardware and operating system platforms, from desktop to mainframe. Therefore, when you scale your Oracle7 database and applications from one platform to another, it is transparent to the users.

The Oracle7 Workgroup Server is bundled with a set of graphical database administration tools to enable you to perform the common database administration tasks in a graphical user interface environment. An authorized administrator can easily manage and maintain the database with these tools without typing in any SQL command.

The Oracle7 Workgroup Server also comes with an initial or seed database that has been preconfigured for the workgroup environment. The initial database contains four tablespaces: SYSTEM, USER_DATA, TEMPORARY_DATA, and ROLLBACK_DATA. When you use the User Manager tool to create a new database user account, its default tablespace will be USER_DATA and its temporary tablespace will be TEMPORARY_DATA. The initial database defaults to NOARCHIVELOG mode. You can change it to ARCHIVELOG mode to archive redo log files.

The Oracle7 Workgroup Server is tightly integrated with the operating system (OS) to produce the optimal performance. The Oracle7 Workgroup Server supports symmetric multiprocessing (SMP), asynchronous I/O, and the direct file system support on most of the Desktop and Intel UNIX platforms. It also supports OS registry on Windows NT and OS threads on the Windows NT, NetWare, and OS/2 platforms. Table 57.1 summarizes the current operating system integration support.

System Requirements

This section specifies the minimum hardware and software requirements to install the Oracle7 Workgroup Server. The hardware and software requirements depend on many factors, such as the size of the Oracle database System Global Area (SGA), the number of current client connections, and the applications installed on the system. You need to refer to your Oracle7 Workgroup Server User's Guide for detailed information on how to determine your system requirements. This section also provides several tips on installing and using the Oracle7 Workgroup Server.

Server Hardware Requirements

This section describes the minimum server hardware requirements for installing and running the Oracle7 Workgroup Server.


During the installation of the Oracle7 Workgroup Server for Intel UNIX, the relinking process requires swap space, which should be at least twice the size of the total physical memory installed in your server. For example, if you have 32 MB of RAM in your server, the swap space should be at least 64 MB.


Before you install the Oracle7 Workgroup Server for NetWare, you might want to make sure the NetWare operating system recognizes all the memory that you install on the server. You can issue the MEMORY command at the server console prompt to find out how much memory is recognized by NetWare.


If the installation of the Oracle7 Workgroup Server for Intel UNIX fails because of lack of disk space, you might need to remove any partially installed products from the Oracle home directory. If you install the Oracle7 Workgroup Server from a temporary stage home directory, you might need to delete that directory and rebuild it. Remember that the Oracle Installer does not recognize any symbolic links in the Oracle home directory when the Oracle Installer calculates free disk space. If you are sure that you have enough free disk space to complete the installation, you can ignore the insufficient space warning from the Oracle Installer.

Server Operating System Requirements

This section describes the minimum server operating system requirements for installing and running the Oracle7 Workgroup Server.


To avoid a possible server crash or abend problem, before you install the Oracle7 Workgroup Server for NetWare, you might need to apply the latest NetWare operating system patches from Novell. You might also need to install the latest disk driver(s) (.DSK) for your disk controller and the latest LAN (.LAN) driver(s) for the network interface card(s) (NIC) on your NetWare server. The "Novell Server Library NLM Updates" release notes for the Oracle7 Workgroup Server for NetWare list the required patch files from Novell.


When you are installing the Oracle7 Workgroup Server for Intel UNIX and it fails in the relinking phase, you might not have the make utility or the networking software libraries installed on your system. You can verify the make utility by following one of the steps below:

UnixWare: Make sure that /usr/bin/make is
linked to /opt/oracle/bin/make.

SCO: Make sure that the make utility is
installed under the /bin directory. The make
utility is automatically installed with the
SCO Development System installation.

Solaris x86: Make sure that the make utility
is in the /usr/ccs/bin directory.


For the Oracle7 Workgroup Server for Intel UNIX, the ORACLE_HOME, ORACLE_SID, ORACLE_TERM, PATH, SHELL, and DISPLAY environment should be set properly in the .profile or .login file.

Client System Requirements

This section describes the minimum client system requirements for installing and running the client system of the Oracle7 Workgroup Server.

Oracle7 Workgroup Server Tools and Utilities

The Oracle7 Workgroup Server tools and utilities are listed in Table 57.2. Most of the Oracle database user tools are discussed in Chapter 56. Some of them, such as Start Oracle, Stop Oracle, and the Maintenance Manager, are specific to the Intel UNIX servers. They are introduced in the following sections. This section also introduces the Network Manager for Windows. For a detailed description, refer to your Oracle7 Workgroup Server User's Guide and the Oracle Database Tools User's Guide.

In the Oracle7 Workgroup Server for the Intel UNIX, most of the database administration tools can be executed from the Oracle Admin toolbar. You can bring up the Oracle Admin toolbar from an xterm window by entering the following command at the operating system prompt:

     $  otoolbar

The Oracle Admin toolbar contains the icons for most of the database tools, such as the Database Manager, Database Expander, Object Manager, User Manager, Backup Manager, and Start Oracle Networks.

Start Oracle Networks for Intel UNIX

You use the Start Oracle Networks to start up the SQL*Net listener on your Oracle7 Workgroup Server to accept SQL*Net client connections. You can execute this utility by clicking the Start Oracle Networks icon from the Oracle Admin toolbar. The processes start running in the background, and a minimized xterm window appears at the bottom of your screen. If you want to see what processes are running, you can maximize the xterm window at the bottom of your screen. The xterm window disappears when all its processes are completed.

After the Oracle7 Workgroup Server installation, it is not necessary to use Start Oracle Networks to start up the SQL*Net listener. You might need to use the Start Oracle Networks utility to activate the SQL*Net listener after you install a patch, reconfigure your networks, or after a system crash.

Stop Oracle Networks for Intel UNIX

The Stop Oracle Networks utility is for shutting down the SQL*Net listener. After the SQL*Net listener has been shut down, the database will not receive any SQL*Net client connections. You can execute this utility by clicking the Stop Oracle Networks icon from the Oracle Admin toolbar. The processes start running in the background and a minimized xterm window appears at the bottom of your screen. If you want to see what processes are running, you can maximize the xterm window at the bottom of your screen. The xterm window disappears when all Stop Oracle Networks processes are completed. It is appropriate to use the Stop Oracle Networks utility to shut down the SQL*Net listener before you reconfigure your networks and install a patch.

Maintenance Manager for Intel UNIX

The Maintenance Manager is used to install or remove patches for Oracle from your Oracle7 Workgroup Server. A patch may be in the form of a file (which can be downloaded from an online bulletin board), or a cartridge tape released by Oracle. There is no icon for the Oracle Maintenance Manager on the Oracle Admin toolbar. You can start the Maintenance Manager from an xterm window by entering the following command at the operating system prompt:

$  mainmgr

The Update button in the Maintenance Manager is used to install patches and the Rollback button is used to remove patches. You can install a patch from a file or from a tape depending on the format and media of the patch.

Network Manager for Windows

Before you start using SQL*Net Version 2, you might need to create or modify several configuration files, such as LISTENER.ORA and TNSNAMES.ORA. These files are not easy to create or modify manually because they need to follow certain syntax for different network protocols. The Network Manager for Windows is a graphical tool, and it enables you to create these configuration files by entering the necessary information on the screen. Before the Network Manager generates the configuration files, it validates the information that you enter and warns you if it discovers any inconsistency. Figure 57.1 shows the Network Manager dialog box.

When To Use Oracle7 Workgroup Server

Because of the similarities among the Oracle7 Server, Oracle7 Workgroup Server, and Personal Oracle7, it is not obvious which product meets the needs of your client/server applications. This section suggests when it is appropriate to use the Oracle7 Workgroup Server and how Oracle7 Workgroup Server meets your business and technical needs.

The Oracle7 Workgroup Server is appropriate in the following situations:

Summary

This chapter discussed the Oracle7 Workgroup Server, the major server and client components of the Oracle7 Workgroup Server, and the system requirements. We have compared the Oracle7 Workgroup Server with other Oracle packages and explained when it is appropriate to use the Oracle7 Workgroup Server. The Oracle7 Server for the desktop platform is discussed in the next chapter.
