2 Database Tools on Windows

Oracle Database for Windows includes various tools to perform database functions. This chapter describes preferred tools to perform common database administration tasks and explains how tools can be started.

Unless otherwise noted, features described in this guide are common to Oracle Database Enterprise Edition, Oracle Database Standard Edition, and Oracle Database Personal Edition.

This chapter contains these topics:

Choosing a Database Tool

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 preferred tools to use for common database administration tasks.

Note:

Oracle Server Manager is no longer shipped as of Oracle9i release 2 (9.2). All Server Manager text and examples have been replaced with SQL*Plus equivalents.

Additionally, connecting to the database as CONNECT INTERNAL is no longer supported.

SQL> CONNECT INTERNAL/password@tnsalias 

has been replaced by:

SQL> CONNECT SYS/password@tnsalias AS SYSDBA 

Database Tools and Operating System Compatibility

Almost all database tools are available on all supported versions of Windows. The following are not supported on Oracle Database for Microsoft Windows Itanium (64-Bit):

  • Pro*COBOL

  • Oracle Portal

  • Oracle Migration Workbench

  • Oracle Objects for OLE

  • Oracle Open Gateways

  • Oracle Transparent Gateways

  • SQL*Plus Worksheet

See Also:

Oracle Database Release Notes for Microsoft Windows Itanium (64-Bit) for a complete list of unsupported features in Oracle Database for 64-bit Windows

Oracle Enterprise Manager and its optional management packs have additional integrated tools to assist in managing databases. See Oracle Enterprise Manager Concepts for more information.

Preferred Database Tools

Table 2-1 lists various database tools you can use to perform common database administration tasks. Oracle recommends you use tools listed in the "Preferred Database Tool" column of the table. After choosing a tool to perform a task, go to Table 2-2, for instructions on how to start the tool.

Note:

The VOLSIZE parameter for Export and Import utilities is not supported on Windows. If you attempt to use the utilities with the VOLSIZE parameter, then error LRM-00101 occurs. For example:
D:\> exp system/manager full=y volsize=100m;
LRM-00101: unknown parameter name 'volsize'
EXP-00019: failed to process parameters, type 'EXP HELP=Y' for help
EXP-00000: Export terminated unsuccessfully

  • User Migration Utility can migrate local or external users to enterprise users. For more information, see "Using the User Migration Utility" in Oracle Database Advanced Security Administrator's Guide.

  • Data Pump Export and Data Pump Import are preferred for Oracle Database 10g Release 1 (10.1) and later data; Export and Import are preferred for earlier data.

  • Oracle Database Upgrade Assistant can upgrade the following databases to the current release: Oracle9i release 2 (9.2) and Oracle Database 10g Release 1 (10.1).

  • 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.

  • Oracle Database for 64-bit Windows supports enterprise users and roles stored in Oracle Internet Directory, but administration tools must be run from a 32-bit computer.

  • You cannot use earlier versions of Oracle Wallet Manager to manage Oracle Database 10g Release 1 (10.1) or later wallets that contain password-based credentials for authentication to Oracle Internet Directory. These credentials are placed in the wallet when an Oracle Database server is registered in Oracle Internet Directory.

    The database wallet that Database Configuration Assistant automatically generates during database registration can only be used with an Oracle Database 10g Release 1 (10.1) or later server. You cannot use this database wallet for earlier versions of the database, nor can you use it for Oracle Internet Directory Release 9.0.4 or earlier.

  • For guidelines on creating database objects, see Oracle Database Administrator's Guide.

  • Oracle Enterprise Manager Grid Control can manage a 64-bit Windows database from a remote Linux or Windows 32-bit computer.

  • Oracle Enterprise Manager Console is not supported in Oracle Database for 64-bit Windows.

Starting Database Tools

This section describes how to start each of the database tools in the following categories:

Starting Database Tools in Multiple Oracle Homes

If you have multiple Oracle homes on your computer from previous releases, then see Appendix B, "Optimal Flexible Architecture", in Oracle Database Installation Guide for Microsoft Windows Itanium (64-Bit) for a description of differences between Oracle homes in different releases.

Starting Tools from Oracle8i Release 8.1.3 and Later Multiple Oracle Homes

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. To start Oracle Administration Assistant for Windows from any Oracle home, choose Start > Programs > Oracle - HOME_NAME > Configuration and Migration Tools > Administration Assistant for Windows.

Starting Database Tools on Windows Server 2008 and Windows Server 2008 R2

To ensure that only trusted applications run on your computer, Windows Server 2008 and Windows Server 2008 R2 provide User Account Control. If you have enabled this security feature, then, depending on how you have configured it, Oracle Universal Installer prompts you for either your consent or your credentials when installing Oracle Database Client. Provide either the consent or your Windows Administrator credentials as appropriate.

You must have Administrator privileges to run some configuration tools, or to run any tool or application that writes to any directory within the Oracle home. If User Account Control is enabled, and you are logged in as the local Administrator, then you can successfully run each of these commands in the usual way. However, if you are logged in as a member of the Administrator group, then you must explicitly invoke these tasks with Windows Administrator privileges.

The following tools must be run with Administrator privileges:

  • Oracle Administration Assistant for Windows. This tool is available as a Configuration and Migration Tool.

  • Oracle Net Configuration Assistant. This tool is available as a Configuration and Migration Tool.

  • Oracle OPatch. This tool allows the application and rollback of interim patches to Oracle products.

  • Oracle OLAP Analytic Workspace Manager and Worksheet. This tool is available as an Integrated Management Tool.

  • Oracle Database Configuration Assistant. This tool is available as a Configuration and Migration Tool.

  • Oracle Database Wallet Manager. This tool is available as an Integrated Management Tool.

  • Oracle Database Upgrade Assistant. This tool is available as a Configuration and Migration Tool.

  • Oracle Net Manager. This tool is available as a Configuration and Migration Tool.

  • Oracle ASM Disk Stamping Tool (asmtoolg). This tool is available as a Configuration and Migration Tool.

To create a Windows shortcut with Windows Administrator privileges:

  1. Click the Start menu button.

  2. Navigate to Programs, then to Oracle - HOME_NAME.

  3. Right-click the name of the command or application you want to run, then select Run as administrator.

To start a command prompt window with Windows Administrator privileges:

  1. On your desktop, create a shortcut for the command prompt window. An icon for that shortcut appears on the desktop.

  2. Right-click the icon for the newly created shortcut, and specify Run as administrator.

When you open this window, the title bar reads Administrator: Command Prompt. Commands run from within this window are run with Administrator privileges.

Starting Database Tools from the Start Menu

Table 2-2 describes how to start assistants and other tools from the Start Menu. It also tells where to go for further information about 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 Oracle Database, you must have an administrative privilege. If you run Database Configuration Assistant from an account that is not part of the Administrators group, then the tool exits without completing the operation.

Note:

All Start Menu paths begin with choose Start > Programs > Oracle - HOME_NAME >.

Note:

Three special conditions apply when running Export or Import utilities on Windows. First, default values for BUFFER and RECORDLENGTH parameters are 4 KB and 2 KB respectively. This default RECORDLENGTH parameter does not depend on the value of BUFSIZ defined in the system header file. If you specify a value larger than USHRT_MAX (64 KB), you will get a warning message. Second, the VOLSIZE parameter is not supported. Third, to export an entire database, you must use the EXP_FULL_DATABASE role.

Using SQL*Loader

This section describes Windows-specific information for using SQL*Loader (SQLLDR).

Windows Processing Options

This section discusses possible values for the operating system dependent file processing specifications string option (os_file_proc_clause), referred to in "Specifying Datafile Format and Buffering" in Chapter 8, "SQL*Loader Control File Reference", in Oracle Database Utilities.

Default (No Processing Option) or "str terminator_string"

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-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). Maximum record size is 48 KB.

When processing stream format data files, SQL*Loader can usually recognize record terminators automatically, whether they are Windows-style or UNIX-style. So you usually do not need to specify which record terminator you are using.

For external table loads, however, only Windows-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 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.

"FIX n"

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.

"VAR 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.

Case Study Files

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.

Specifying the Bad File

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 Database 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 want to retain.

Control File Conventions

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 2-5 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.

Footnote 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.

Oracle Database Utilities for a complete list of options and instructions on using SQL*Loader

Using Windows Tools

You can use Windows tools in various ways to manage Oracle Database:

Using Event Viewer to Monitor a Database

Event Viewer lets you monitor events in your system. An event is an important occurrence in the system or application (such as 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:

  • Initialization of System Global Area for active instance

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

  • Connection to Oracle Database using AS SYSDBA

In addition, the operating system audit trail is logged to Event Viewer.

See Also:

Chapter 6, "Monitoring a Database on Windows" for specific instructions on accessing and using Event Viewer to monitor Oracle Database events

Using Microsoft Management Console to Administer a Database

Microsoft Management Console provides a central location for network administration. Microsoft Management Console hosts applications (called snap-ins) that administrators can use to manage their networks. Oracle snap-ins enable database administrators to:

  • Configure Oracle Database administrators, operators, users, and roles so the Windows operating system can authenticate them

  • Configure OracleServiceSID

  • Modify registry parameters for all Oracle homes on the computer

  • Modify the computer host name, username, and password for the database being monitored by Oracle Counters for Windows Performance Monitor

  • View and terminate an Oracle Database thread

Using Oracle Counters for Windows Performance Monitor

Oracle Counters for Windows Performance Monitor is integrated into Windows Performance Monitor. This tool enables you to view 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 as charts, alerts, and reports.

You can use Oracle Counters for Windows Performance Monitor to monitor key Oracle 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.

See Also:

"Using Oracle Counters for Windows Performance Monitor" for specific instructions on accessing and using Oracle Counters for Windows Performance Monitor to monitor Oracle Database performance

Using Registry Editor to Modify Configuration Information

Oracle Database stores its configuration information in a structure known as the registry. You can view and modify this configuration information through 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.

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, 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 started and whenever an Oracle Database product is started. These parameters include settings for:

  • Oracle home directory

  • Language

  • Company name

  • Oracle home subdirectories for individual products

  • Individual products such as SQL*Plus

  • Services

    See Also:

    Chapter 14, "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

Using Task Manager to Monitor Applications and Processes

Task Manager has three tabs:

  • Applications tab displays what applications are running. This is useful for identifying and ending unresponsive tasks. (Oracle Database does not appear as an application because it runs as a service.)

  • Processes tab displays details of currently running processes and their resource usage. Columns are customizable.

  • Performance tab graphically displays real-time CPU and memory usage, which is useful for spotting sudden changes.

Using Local Users and Groups to Manage Users and Groups

Local Users and Groups enables you to manage users and groups on Windows. Specifically, you can:

  • Create and modify local user accounts

  • Create and modify user profiles

  • Create, add, and delete local groups
