B.1 What is the Tools Instant Client?

The Tools Instant Client package is available on platforms that support the OCI Instant Client.

The Tools package contains several command-line utilities, including SQL*Loader, Data Pump Export, Data Pump Import, Original (classic) Export, and Original (classic) Import. Instant Client installations are standalone, with all the functionality of the command-line versions of the products. The Instant Client connects to existing remote Oracle databases, but does not include its own database. It is easy to install and uses significantly less disk space than the full Oracle Database Client installation required to use the command-line versions of products.

See the Oracle Call Interface Programmer's Guide for more information about the OCI Instant Client.

To use the Tools Instant Client, you need two packages:

  • Tools Instant Client Package

  • Either the Basic OCI Instant Client package, or the OCI Instant Client Light package.

The basic steps required to use the Tools Instant Client are as follows. Each of these steps is described in this appendix.

  1. Choose which OCI Package (Basic or Light) you want to use, and also select the directory in which to install the Instant Client files.

  2. Copy the Tools Instant Client Package, and the OCI Instant Client package of your choice, from an installed Oracle instance or download them from OTN.

  3. Install (unpack) the Tools Instant Client package and the OCI package. A new directory instantclient_12_2 is created as part of the installation.

  4. Configure the Instant Client.

  5. Connect to a remote instance with the utility you want to run.

Both the Tools package and OCI package must be from Oracle Database version 12.2.0.0.0, or higher, and the versions for both must be the same.

B.2 Choosing the Instant Client to Install

Before you install the Tools Instant Client Tools package, you must first choose either Basic Instant Client or Instant Client Light.

Basic Instant Client

The Tools Instant Client package, when used with Basic Instant Client works with any NLS_LANG setting supported by the Oracle Database. It supports all character sets and language settings available in the Oracle Database.

Instant Client Light

The Instant Client Light (English) version of Instant Client further reduces the disk space requirements of the client installation. The size of the library has been reduced by removing error message files for languages other than English and leaving only a few supported character set definitions out of around 250.

Instant Client Light is geared toward applications that use either US7ASCII, WE8DEC, WE8ISO8859P1, WE8MSWIN1252, or a Unicode character set. There is no restriction on the LANGUAGE and the TERRITORY fields of the NLS_LANG setting, so the Instant Client Light operates with any language and territory settings. Because only English error messages are provided with the Instant Client Light, error messages generated on the client side, such as Net connection errors, are always reported in English, even if NLS_LANG is set to a language other than AMERICAN. Error messages generated by the database side, such as syntax errors in SQL statements, are in the selected language provided the appropriate translated message files are installed in the Oracle home of the database instance.

B.5 Configuring Tools Instant Client Package

The Tools Instant Client package executable should only be used with the matching version of the OCI Instant Client. No ORACLE_HOME or ORACLE_SID environment variables need to be set.

Configuring Tools Instant Client Package (from RPMS) on Linux

The RPMs downloaded from OTN install into Oracle specific sub-directories in the /usr file system. The subdirectory structure enables multiple versions of Instant Client to be available.

  1. Add the name of the directory containing the Instant Client libraries to LD_LIBRARY_PATH. Remove any other Oracle directories.

    For example, to set LD_LIBRARY_PATH in the Bourne or Korn shells, use the following syntax:

    Or, to set LD_LIBRARY_PATH in the C shell, use the following syntax:

  2. Make sure the Tools executables installed from the RPM are the first executables found in your PATH. For example, to test this you could enter which sqlldr which should return /usr/bin/sqlldr. If it does not, then remove any other Oracle directories from PATH, or put /usr/bin before other Tools executables in PATH, or use an absolute or relative path to start Tools Instant Client.

    For example, to set PATH in the bash shell:

  3. Set Oracle globalization variables required for your locale. A default locale will be assumed if no variables are set.

  1. Add the name of the directory containing the Instant Client files to the appropriate shared library path LD_LIBRARY_PATH, LIBPATH or SHLIB_PATH. Remove any other Oracle directories.

    For example on Solaris in the Bourne or Korn shells:

  2. Add the directory containing the Instant Client files to the PATH environment variable. If it is not set, then an absolute or relative path must be used to start the utilities provided in the Tools package. Remove any other Oracle directories from PATH. For example:

  3. Set Oracle globalization variables required for your locale. A default locale will be assumed if no variables are set. For example:

Configuring Tools Instant Client Package on Windows

The environment may be configured using SET commands in a Windows command prompt or made permanent by setting Environment Variables in System Properties.

For example, to set environment variables in Windows 2000 using System Properties, open System from the Control Panel, click the Advanced tab and then click Environment Variables.

  1. Add the directory containing the Instant Client files to the PATH system environment variable. Remove any other Oracle directories from PATH.

    For example, add c:instantclient12_2 to the beginning of PATH.

  2. Set Oracle globalization variables required for your locale. A default locale will be assumed if no variables are set.

    For example, to set NLS_LANG for a Japanese environment, create a user environment variable NLS_LANG set to JAPANESE_JAPAN.JA16EUC.

B.6 Connecting to a Database with the Tools Instant Client Package

Instant

After the Tools Instant Client package is installed and configured, you can connect to a database.

The utilities supplied in the Tools Instant Client are always remote from any database server. It is assumed that the server has an Oracle instance up and running and has the TNS listener running. For the Data Pump Export and Import clients, the dump files reside on the remote server; an Oracle directory object on the server must exist and should have the appropriate permissions.

To connect to a database you must specify the database using an Oracle Net connection identifier. The following information uses the SQL*Loader (sqlldr) utility, but the information applies to other utilities supplied in the Tools Instant Client package as well.

An example using an Easy Connection identifier to connect to the HR schema in the MYDB database running on mymachine is:

Alternatively you can use a Net Service Name:

Oracle Instant Client Download Linux

Net Service Names can be stored in a number of places, including LDAP. The use of LDAP is recommended to take advantage of the new features of Oracle Database 12c

To use Net Service Names configured in a local Oracle Net tnsnames.ora file, set the environment variable TNS_ADMIN to the directory containing the tnsnames.ora file. For example, on UNIX, if your tnsnames.ora file is in /home/user1 and it defines the Net Service Name MYDB2:

If TNS_ADMIN is not set, then an operating system dependent set of directories is examined to find tnsnames.ora . This search path includes looking in the directory specified by the ORACLE_HOME environment variable for network/admin/tnsnames.ora . This is the only reason to set the ORACLE_HOME environment variable for SQL*Loader Instant Client. If ORACLE_HOME is set when running Instant Client applications, it must be set to a directory that exists.

This example assumes the ORACLE_HOME environment variable is set, and the $ORACLE_HOME/network/admin/tnsnames.ora or ORACLE_HOMEnetworkadmintnsnames.ora file defines the Net Service Name MYDB3:

The TWO_TASK (on UNIX) or LOCAL (on Windows) environment variable can be set to a connection identifier. This removes the need to explicitly enter the connection identifier whenever a connection is made in SQL*Loader or SQL*Loader Instant Client. This UNIX example connects to the database known as MYDB4:

On Windows, TNS_ADMIN and LOCAL may be set in the System Properties.
