linux环境下oracle client安装和配置

oracle客户端的安装是非常简单的，关键在tns配置，我这里使用的rpm安装包，oracle本身就不是开源，那使用rpm安装时最简单的。

1. 要远程使用oracle，先下载下面三个文件，注意版本最好一致。

oracle-instantclient-basic-10.2.0.4-1.i386.rpm

oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm

oracle-instantclient-devel-10.2.0.4-1.i386.rpm

2. RPM安装

oracle-instantclient-basic-10.2.0.4-1.i386.rpm是基本的动态库、jar包，默认安装路径是：/usr/lib/oracle/10.2.0.4/client

oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm是客户端sqlplus安装包, 默认安装路径是：/usr/lib/oracle/10.2.0.4/client

oracle-instantclient-devel-10.2.0.4-1.i386.rpm是api接口文件,默认安装路径是：/usr/include/oracle/10.2.0.4/client

这里不需要修改默认路径,直接安装即可：

sudo rpm-avi oracle-instantclient-basic-10.2.0.4-1.i386.rpm

sudo rpm-avi oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm

sudo rpm-avi oracle-instantclient-devel-10.2.0.4-1.i386.rpm



3. 配置环境变量

vi /etc/profile

export ORACLE_HOME=/usr/lib/oracle/10.2.0.4

export TNS_ADMIN=$ORACLE_HOME/network/admin

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

exportLD_LIBRARY_PATH=$ORACLE_HOME/client/lib:$LD_LIBRARY_PATH

exportOCI_HEADERS_HOME=/usr/include/oracle/10.2.0.4/client

export OCI_LIBS_HOME=$ORACLE_HOME/client/lib

后面两项是为了我们的程序程序编译时使用方便，编译时直接加入选项：

-I$( OCI_HEADERS_HOME) –L$( OCI_LIBS_HOME) –l
occi



4. 配置监听器和网络环境

[huangxw@ubuntu admin]$

cat/usr/lib/oracle/10.2.0.4/network/admin/tnsnames.ora

test_base=

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = *.*.*.*)(PORT = ****))

)

(CONNECT_DATA =

(SERVICE_NAME = tt4adol)

)

)

5. 测试连接

[huangxw@ubuntu bin]$./sqlplus USERNAME/PASSWD@test_base
