|
Oracle9i for Windows includes various tools to perform database functions. This chapter describes the preferred tools to perform common database administration tasks and explains how the tools can be started.
Unless otherwise noted, the features described in this manual are common to Oracle9i Enterprise Edition, Oracle9i Standard Edition, and Oracle9i Personal Edition.
This chapter contains these topics:
Database tools is a collective term for tools, utilities, and assistants that you can use to perform database administration tasks. Some database tools perform similar tasks, though no one database tool performs all database administration tasks. The following sections indicate which database tools can be used on particular operating systems and the preferred tools to use for common database administration tasks.
Table 5-1 lists database tools and the operating system(s) on which each can be used.

ORADIM can only set a password when none was previously set. If a password has been previously set, then ORADIM can change it only by deleting and recreating the Oracle9i services. 2 Oracle Data Migration Assistant can migrate an Oracle7 release 7.3.4 database to the current release; it can also upgrade Oracle8 release 8.0.6 and Oracle8i release 8.1.5, 8.1.6, and 8.1.7 databases to the current release. 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 one Oracle7 database to another. 3 Required when upgrading Oracle Real Application Clusters systems. 4 If you back up files while you are shutting down the database, then your backup will be invalid. You cannot use an invalid backup to restore files at a later date. 5 See Oracle9i Database Administrator's Guide for guidelines on creating database objects. |
This section describes how to start each of the database tools in the following categories:
You will be referred back to this section for database tool startup procedures as you use this manual.
If you have multiple Oracle homes on your computer from previous releases, then see Chapter 6, "Multiple Oracle Homes and Optimal Flexible Architecture" for a description of the differences between Oracle homes before and after Oracle9i release 1 (9.0.1).
If you are using multiple Oracle homes, then the command to start a tool from any home other than the first includes a HOME_NAME, where HOME_NAME indicates the name of that Oracle home. The first Oracle home created on your computer does not have HOME_NAME appended to the group. For example:
To start Oracle Administration Assistant from the first Oracle home, choose:
Start > Programs > Oracle > Configuration and Migration Tools > Administration Assistant for Windows NT
To start Oracle Administration Assistant from an additional Oracle home, choose:
Start > Programs > Oracle - HOME_NAME > Configuration and Migration Tools > Administration Assistant for Windows NT
Beginning in Oracle8i release 8.1.3, each Oracle home, including the first Oracle home you create on your computer, has a unique HOME_NAME. For example:
To start Oracle Administration Assistant from any Oracle home, choose:
Start > Programs > Oracle - HOME_NAME > Configuration and Migration Tools > Administration Assistant for Windows NT
Table 5-3 describes how to start assistants and other tools from the Start Menu. It also tells where to go for further information on using these products.
Note: When you use an assistant, you must have read and write access to the directory where database files will be moved or created. To create an Oracle9i database, you must have an administrative privilege. If you run Oracle Database Configuration Assistant from an account that is not part of the Administrators group, then the tool exits without completing the operation. |

The Oracle Enterprise Manager Console can be started:
C:\> oemapp console
You are prompted to choose between logging in to a Management Server or starting in standalone mode.
Choose standalone when you want to connect directly to your database(s) to perform administrative tasks. The first time Enterprise Manager is started in standalone mode, the Add Database To Tree dialog appears, allowing you to add your database(s) to Enterprise Manager's navigation tree. For more information, see "Standalone" in the Oracle Enterprise Manager Configuration Guide.
In Standalone mode you will not have access to functionality typically available through the Management Server and Intelligent Agent, however, because they are not required in standalone mode. These unavailable features include:
These features are all available when you choose to log in to a Management Server, which is automatically installed and configured during standard Oracle9i Database installation types. If you performed a custom database installation, however, you may need to install and configure a Management Server. For installation instructions, see your Oracle9i Database installation guide for Windows. For configuration instructions, see "Configuring and Controlling the Management Server" in the Oracle Enterprise Manager Configuration Guide.
If this is your first login to a Management Server, you must enter the default Enterprise Manager administrator name sysman
and its password oem_temp
. The Management Server on the node you select or enter must already be configured with the repository you want to access. For more information, see "Configuring the Console When Connected to a Management Server" in the Oracle Enterprise Manager Configuration Guide.
The Enterprise Manager Web site component is installed in the ORACLE_HOME
\oem_webstage
directory by default. In addition, the Enterprise Manager Web site automatically installs a preconfigured Oracle HTTP server to act as its Web server.
If you want to use a Web server other than the default preconfigured Oracle HTTP server, you must install and manually configure it. Additional supported Web servers include:
http://webserver_hostname:port number/
where webserver_hostname
is the name of the Web server computer, and port number
is whatever the Web server is configured for. The port number of the default preconfigured Oracle HTTP Server is 3339.
The Enterprise Manager page appears, allowing you to start the Enterprise Manager Console, view previously published Enterprise Manager reports, or link to other sites.
.
Administrator = sysman
Password = oem_temp
These credentials are for the default super administrator account. The first time you start Enterprise Manager, you must log in as the super administrator. After other administrator accounts have been created using the super administrator account, you can log in as a different administrator.
Note: Enterprise Manager must be configured before the reports access feature will work. See the Oracle Enterprise Manager Configuration Guide for information on:

This section describes Windows-specific information for using SQL*Loader (SQLLDR
).
This section discusses 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 Oracle9i Database Utilities.
Stream record format in which each record is terminated by a record terminator. If "str terminator_string" is not specified, then the record terminator defaults to either the Windows NT-style record terminator (the two-character sequence carriage return, \r, followed by line feed, \n) or the UNIX-style record terminator (single-character line feed, \n). The maximum record size is 48 KB.
When processing stream format data files, SQL*Loader can usually recognize record terminators automatically, whether they are Windows NT-style or UNIX-style. So you usually do not need to specify which record terminator you are using.
For external table loads on NT, however, only the Windows NT-style record terminators are recognized automatically. If your data file contains UNIX-style record terminators, you must specify the record terminator. If you are using SQL*Loader (with the external_table
option), then specify the UNIX-style record terminator by specifying "str
'\n'"
on the INFILE line in the SQL*Loader control file. For example:
INFILE mydata.dat "str '\n'"
You can also specify the record terminator in hex, by specifying "str x'0a'"
(assuming an ASCII-based character set). For example:
INFILE mydata.dat "str x'0a'"
Note that the "0" (zero) before the "a" is required. If you are using SQL with an access parameter list to create the external table, then you must specify '\n'
in a RECORDS
DELIMITED
BY
clause. For example:
RECORDS DELIMITED BY '\n'
You can also use a hex string in this case. For example:
RECORDS DELIMITED BY 0x'0a'
Note that in this case, the "0" (zero) before the "x" and the "0" (zero) before the "a" are both required.
Fixed record format in which each record is exactly n
bytes long. Record terminators are not required with fixed record format. If the record includes a record terminator, then the record terminator bytes are included in the number of bytes n
.
Variable record format in which the length of each record in a character field is included at the beginning of each record in the datafile. Record terminators are not required with the variable record format. This format provides some added flexibility over the fixed record format and a performance advantage over the stream record format. You can specify a datafile that is to be interpreted as being in variable record format as follows:
INFILE "mydata.dat" "var n"
In this example, n
specifies the number of bytes in the record length field. If n
is not specified, SQL*Loader assumes a length of 5 bytes. Specifying n
larger than 40 will result in an error. Lengths are always interpreted in bytes, even if character-length semantics are in effect for the file. This is necessary because the file could contain a mix of fields, some processed with character-length semantics and others processed with byte-length semantics.
The distribution media for SQL*Loader contains case study files for control files, datafiles, and setup files in ulcase1,...ulcase11
in the following directory: ORACLE_HOME
\rdbms\demo.
When SQL*Loader executes, it can create a file called a bad file or reject file in which it places records that were rejected because of formatting errors or because they caused Oracle errors. If you have specified that a bad file is to be created, it overwrites any existing file with the same name; ensure that you do not overwrite a file you wish to retain.
When preparing SQL*Loader control files (.ctl
), you must follow certain syntax and notational conventions.
In full path descriptions, backslashes do not require escape characters or other special treatment. When embedding a single or double quotation mark inside a string delimited by double quotation marks, place a backslash escape character before the embedded quotation mark.
When specifying datatypes in the SQL*Loader control file, note that the default sizes of native datatypes shown in Table 5-6 are specific to Windows. These datatypes can be loaded with correct results only between systems where they have the same length in bytes. You cannot override these defaults in the control file. If the byte order is different between the systems, you can indicate the byte order of the data with the BYTEORDER parameter, or you can place a byte-order mark (BOM) in the file.
Native Datatypes | Default Field Length |
---|---|
DOUBLE |
8 |
FLOAT |
4 |
INTEGERFoot 1 |
4 |
SMALLINT |
2 |
1
The default listed is correct if INTEGER is specified without a size. But INTEGER(n) is also allowed. In that case, n specifies the size of the INTEGER field in bytes. |

The following Windows tools can be used to administer an Oracle database:
Event Viewer lets you monitor events in your system. An event is an important occurrence in the system or application (such as your Oracle database) that requires user notification. While messages for major events can appear on-screen as you work at your computer, events not requiring your immediate attention are recorded by Windows in the Event Viewer log file. You can then view this information at your convenience.
Event Viewer can be used to monitor Oracle database events, such as:
AS
SYSDBA
In addition, the operating system audit trail is logged to Event Viewer.
See Also:
"Monitoring a Database" in Oracle9i Database Administrator's Guide for Windows for specific instructions on accessing and using Event Viewer to monitor Oracle database events |
The Microsoft Management Console provides a central location for network administration. The Microsoft Management Console hosts applications (called snap-ins) that administrators can use to manage their networks. The Oracle snap-ins enable database administrators to:
OracleService
SID
Oracle Performance Monitor for Windows NT is integrated into Microsoft's Performance Monitor. 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.
You can use Oracle Performance Monitor to monitor key Oracle database information, such as:
You can use your findings to improve database performance.
See Also:
"Using Oracle Performance Monitor for Windows NT" in Oracle9i Database Administrator's Guide for Windows for specific instructions on accessing and using the Oracle Performance Monitor to monitor Oracle database performance |
The Oracle9i 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 format similar to Windows Explorer. In the left-hand window is a tree-like format consisting of keys (or folders). When one of these keys is highlighted, the parameters and values assigned to that key are displayed in the right-hand window.
When you install products from your CD-ROM, configuration parameters are automatically entered in the registry. These parameters are read each time your Windows computer is restarted and whenever an Oracle product is started. These parameters include settings for:
Chapter 9, "Configuration Parameters and the Registry" for definitions of Oracle database configuration parameters and specific instructions on using the registry to modify Oracle database configuration parameters
