See "Using the ORADEBUG Utility" in Chapter 10, "Administering a Database".

Preferred Database Tools

This table lists common database administration tasks and the various database tools you can use to perform them. Oracle Corporation recommends you use the tools listed in the "Preferred Database Tool" column of the table. After choosing a tool to perform a task, go to "Starting Database Tools" in this chapter for instructions on how to start the tool.

1 Instance Manager can start up and shut down a database and perform other limited functions. This tool cannot be used to create database services, or create and delete databases. Instance Manager is an Oracle Enterprise Manager tool. 2 ORADIM80 can only set a password when none was previously set. Also, ORADIM80 can change a password by deleting and recreating the Oracle8 services. 3 Oracle Data Migration Assistant can only be used to upgrade release 8.0.3 databases to release 8.0.4. It cannot be used to upgrade an earlier Oracle7 database release to a later Oracle7 database release. See your Oracle7 for Windows NT documentation for information on how to upgrade from an earlier Oracle7 release to a later Oracle7 release. 4 Do not back up files while you are shutting down the database, otherwise your backup will be invalid. You cannot use an invalid backup to restore files at a later date. 5 See Oracle8 Administrator's Guide for guidelines on creating databases objects. In particular, see Appendix A, "Space Estimations for Schema Objects" which provides equations for estimating the space requirements for clusters, non-clustered tables, and indexes. Windows NT uses the same fixed header, transaction header, and row header constants described in that guide.

Using SQL*Loader

This section describes Windows NT specific information for using SQL*Loader (SQLLDR80).

Windows NT Processing Options

These are the possible values for the Operating System Dependent (OSD) file processing specifications string option, referred to in the "SQL*Loader Control File Reference" chapter of Oracle8 Utilities.

Processing Option	Description
""1	Stream record format in which each record is terminated by a newline character. The maximum record size is 48 KB.
"FIX n"	Fixed record format in which each record is exactly n bytes long. If the record is terminated by a newline character, the newline character must be the nth byte.
"VAR xxxx"	Load variable length records. Specify the OSD "VAR recsizehint" in the control file for this option to take effect. The xxxx gives an estimate of the average record size to SQL*Loader so that it can approximate buffer sizes accurately and not waste memory. The default length is eighty characters. The xxxx does not specify how many leading bytes of length are included in each record. It only acts as a hint to SQL*Loader. Each record must always be preceded by five ASCII bytes containing the length of the remainder of the record. For example, a record must look like the following: 00024This is a 24 byte string Any whitespace, carriage returns, or linefeeds at the end of the record are ignored unless specifically included in the byte count in the length field.

1 Two double quote characters with no space in between.

Direct Path Option

SQL*Loader includes a direct path option that bypasses Oracle8 Enterprise Edition redo log and data verification features, thereby decreasing loading time. Use the direct path option with data files known to be error free.

Control File Conventions

When preparing a SQL*Loader control file (.CTL), you must follow certain syntax and notational conventions. When specifying datatypes in the SQL*Loader control file, note that the default size of native datatypes are specific to Windows NT. You cannot override these defaults in the control file.

Native Datatypes	Default Field Length
DOUBLE	8
FLOAT	4
INTEGER	4
SMALLINT	2

Additional Information: For a complete list of options and instructions on using SQL*Loader, see Oracle8 Utilities. The directory ORACLE_HOME\RDBMS80\LOADER contains a number of examples on the use of SQL*Loader.

Using Windows NT Tools

The following Windows NT tools can be used to administer an Oracle8 database:

• Control Panel

• Event Viewer

• Performance Monitor

• Registry

• User Manager

Control Panel

The Control Panel enables you to modify system options such as computer services. A service is an executable process registered in the registry and administered by Windows NT. The registry automatically tracks and records security information for each service you create.

What Oracle8 Services Appear in the Control Panel?

When you install the Oracle8 database and other products, Oracle services are created and displayed in the Services dialog box:

Use the Services dialog box to start, stop, pause, or continue each of the Oracle services available on the computer, and to pass startup parameters to the service.

Oracle services are the same as Windows NT services. In order to connect to and use an Oracle instance, an Oracle service is created during the database creation process and associated with the Oracle8 database

Once a service is created with your Oracle8 database, the service can run even while no user is logged on. This is because your Oracle8 database starts each instance as a service. This feature enables you to maintain workstation security while running your Oracle8 database.

You can now have multiple, active Oracle home directories on a single computer. This affects the naming conventions for Oracle services. See "Managing Oracle Services" in Chapter 10, "Administering a Database" and Chapter 6, "Using Multiple Oracle Homes" for additional information.

Additional Information: See Chapter 10, "Administering a Database", for specific instructions on using the Control Panel to start and stop Oracle8 database services. See also "Step 1: Start Oracle Services on Managed Oracle8 Database" in Chapter 8, "Post-Installation Configuration Tasks", for specific instructions on using the Control Panel to start the Oracle Intelligent Agent service.

Event Viewer

Event Viewer enables you to monitor events in your system. An event is an important occurrence in the system or application (such as your Oracle8 database) that requires user notification. While messages for major events can display on-screen as you work at your computer, events not requiring your immediate attention are recorded by Windows NT in the Event Viewer log file. You can then view this information at your convenience.

What Oracle8 Database Events Are Monitored?

The Event Viewer can be used to monitor Oracle8 database events, such as:

• initialization of the System Global Area (SGA) for the active instance

• initialization of the Program Global Area (PGA) for the background processes of the active instance

• connection to the Oracle8 database with the CONNECT INTERNAL command

In addition, the operating system audit trail is logged to the Event Viewer. The figure below shows the Event Viewer displaying Oracle8 database events. Double-click an entry to find out specific information about an event.

Additional Information: See Chapter 12, "Monitoring a Database", for specific instructions on accessing and using Event Viewer to monitor Oracle8 database events.

Performance Monitor

Performance Monitor measures computer performance. This tool enables you to view the performance of processors, memory, cache, threads, and processes. Performance information provided includes device usage, queue lengths, delays, throughput measurements, and internal congestion measurements. This information is provided in the form of charts, alerts, and reports.

What Oracle8 Database Information is Monitored?

If you install the Oracle8 Performance Utility from your Oracle8 Enterprise Edition CD-ROM, you can use the Performance Monitor to monitor key Oracle8 database information, such as:

• Library Cache

• Buffer Cache

• Data Dictionary Cache

• Redo Log Buffer Cache

• Thread Activity

You can use your findings to improve database performance. The figure below shows the Performance Monitor monitoring Oracle8 database objects listed at the bottom of the screen:

Additional Information: See Chapter 12, "Monitoring a Database", for specific instructions on accessing and using the Performance Monitor to monitor Oracle8 database performance.

Registry

The Oracle8 database stores its configuration information in a structure known as the registry. You can view and modify this configuration information through the registry editor. The registry contains configuration information for your computer, and must not be accessible for editing by inexperienced users. Only experienced administrators should view and change this information.

The registry editor displays configuration information in a tree-like format consisting of four keys (or folders). These keys are shown in the tree view in the left-hand window. In the right-hand window, the parameters and values assigned to that key are displayed.

What Database Parameters Are Configured?

When you install products from your Oracle8 Enterprise Edition CD-ROM, configuration parameters are automatically entered in the registry. These parameters are read each time your Windows NT computer is restarted. These parameters include settings for:

• Oracle home directory

• Language

• Company name

• Oracle home subdirectories for individual products

• Individual products such as SQL*Plus

• services

The figure below shows some of the Oracle8 database configuration parameters in the registry:

Additional Information: See Appendix C, "Configuration Parameters and the Registry" for definitions of Oracle8 database configuration parameters and specific instructions on using the registry to modify Oracle8 database configuration parameters.

User Manager

User Manager enables you to manage Windows NT computer security and create user accounts.

What Oracle8 Database Tasks Can the User Manager Perform?

With User Manager, you can:

• Grant Oracle8 database roles

• Use operating system authentication for user accounts

• Create an NT user account that enables you to make secure client connections to Oracle8 Enterprise Edition without a password

The figure below shows the User Manager:

Additional Information: See Chapter 11, "Authenticating Database Users with Windows NT" for specific instructions on using User Manager to perform Oracle8 database administration.
