Instant Client Downloads for Linux x86

Installation

See the Instant
Client Home Page for more information.

Installation of ZIP files:

1. Download the desired Instant Client ZIP files. All installations require the Basic or Basic Lite package.
2. Unzip the packages into a single directory such as "/opt/oracle/instantclient_12_1" that is accessible to your application.
3. Create the appropriate libclntsh.so and libocci.so links for the version of Instant Client. For example:

cd /opt/oracle/instantclient_12_1
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so

4. Set the environment variable LD_LIBRARY_PATH to the directory created in Step 2, for example:

export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_1:$LD_LIBRARY_PATH

Alternatively, add this path to an ldconfig configuration file if there is no other Oracle software that will be impacted.

5. To use supplied binaries such as SQL*Plus, update your PATH environment variable, for example:

export PATH=/opt/oracle/instantclient_12_1:$PATH

6. Start your application.

Installation of RPMs:

1. Download the desired Instant Client RPM packages. All installations require the Basic or Basic Lite RPM.
2. As the root user, install the packages with "rpm". For example:

rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.i386.rpm

3. Set the environment variable LD_LIBRARY_PATH to the appropriate directory for the Instant Client version, for example:

export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client/lib:$LD_LIBRARY_PATH

Alternatively, add this path to an ldconfig configuration file if there is no other Oracle software that will be impacted.

4. To use supplied binaries such as SQL*Plus, update your PATH environment variable, for example:

export PATH=/usr/lib/oracle/12.1/client/bin:$PATH

5. Start your application.

centos安装instantclient（oracle精简客户端）步骤

环境

os版本：centos5.5

kernel： 2.6.18-194.el5

下载软件包：

oracle-instantclient-basic-10.2.0.5-1.x86_64.rpm

oracle-instantclient-devel-10.2.0.5-1.x86_64.rpm

oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm

下载地址：

http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

指定rpm包的安装路径

1. 查看rpm包的默认安装路径

[root@localhost tmp]# rpm -qpl oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm

/usr/bin/sqlplus64

/usr/lib/oracle/10.2.0.5/client64/bin/sqlplus

/usr/lib/oracle/10.2.0.5/client64/lib/glogin.sql

3个包都需要检测，为了以后便于维护，可以把instantclient都装在目录"/oracle"

[root@localhost tmp]# rpm -ivh --relocate /usr=/oracle oracle-instantclient-basic-10.2.0.5-1.x86_64.rpm

[root@localhost tmp]# rpm -ivh --relocate /usr=/oracle oracle-instantclient-devel-10.2.0.5-1.x86_64.rpm

[root@localhost tmp]# rpm -ivh --relocate /usr=/oracle oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm

2.sqlnet.ora和tnsnames.ora创建

这两个文件默认是不存在，所以要手工创建

[root@localhost tmp]# mkdir -p /oracle/lib/oracle/10.2.0.5/client64/network/admin

然后在admin目录下创建这两个文件

3.配置环境变量

session级别设置

export LD_LIBRARY_PATH=/oracle/lib/oracle/10.2.0.5/client64/lib

export TNS_ADMIN=/oracle/lib/oracle/10.2.0.5/client64/network/admin

export ORACLE_HOME=/oracle/lib/oracle/10.2.0.5/client64

把如下内容放在环境变量文件中

[root@localhost ~]# vi /root/.bash_profile

.....

TNS_ADMIN=/oracle/lib/oracle/10.2.0.5/client64/network/admin

LD_LIBRARY_PATH=/oracle/lib/oracle/10.2.0.5/client64/lib

PATH=$PATH:$HOME/bin:/oracle/lib/oracle/10.2.0.5/client64/bin

......

4.测试

[root@localhost ~]# sqlplus "/@tns"

SQL*Plus: Release 10.2.0.5.0 - Production on Thu Aug 9 03:03:26 2012

1、用root账号创建Oracle用户

# /usr/sbin/groupadd oinstall
# /usr/sbin/groupadd dba
# /usr/sbin/useradd -m -g oinstall -G dba oracle
# id oracle ( 检查用户名)
# passwd oracle （设置Oracle用户的密码）

2、切换到Oracle账号
．su - oracle

编辑 ~/.bash_profile文件。
umask 022

ORACLE_BASE=/usr/lib/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/12.1/client; export ORACLE_HOME
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib; export LD_LIBRARY_PATH

3、切换到root账号
su - root
在/usr/lib/oracle/11.2/client目录下创建network/admin目录，在此目录下添加tnsnames.ora文件。
