Ubuntu下安装oracle客户端

1) 下载zip包

http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

a. instantclient-basic-linux.x64-11.2.0.4.0.zip

b. instantclient-jdbc-linux.x64-11.2.0.4.0.zip

c . instantclient-sdk-linux.x64-11.2.0.4.0.zip

d. instantclient-sqlplus-linux.x64-11.2.0.4.0.zip

2) 解压到目录

a=> /usr/lib/oracle/11.2/client64/lib

b=> /usr/lib/oracle/11.2/client64/lib

c=> /usr/lib/oracle/11.2/client64/sdk

d=>/usr/lib/oracle/11.2/client64/lib

创建目录和文件连接：

$ sudo mkdir -p /usr/lib/oracle/11.2/client64/sqlplus/mesg
$ cd /usr/lib/oracle/11.2/client64/lib
$ sudo ln -s libclntsh.so.11.1 libclntsh.so
$ sudo ln -s libocci.so.11.1 libocci.so
$ sudo chown cl:cl ./*.so
$ sudo chmod 755 ./*.so

3) tnsnames.ora

$ sudo vi /usr/lib/oracle/11.2/client64/network/admin/tnsnames.ora

内容如下：

ORADBSID =
    (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = ???.xxx.???.???)(PORT = 1521))
        (CONNECT_DATA =
            (SERVER = DEDICATED)
            (SERVICE_NAME = ORCL)
        )
    )

4) 配置 /etc/profile

增加下面内容：

# oracle 11g client x64
export ORACLE_HOME=/usr/lib/oracle/11.2/client64
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=$PATH:$ORACLE_HOME:$ORACLE_HOME/lib:$ORACLE_HOME/sdk/include
export ORACLE_SID=ORADBSID
export NLS_LANG="american_america.ZHS16GBK"

使生效：

. /etc/profile

5) 打开sqlplus

$ sqlplus user/password@ORADBSID
