安装oracle即时客户端

一、需求

数据库和应用没在同一台主机上，所以需要安装oracle即时客户端，也可以是oracle的客户端。只不过客户端比较庞大。

二、安装oracle即时客户端

下载Oracle即时客户端程序包

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

数据库版本是11.2.0.3.0

Instant Client Package - Basic:

All files required to run OCI,OCCI,and JDBC-OCI applications

Image instantclient-basic-linux.x64-11.2.0.3.0.zip (60,331,694 bytes) (cksum - 3890813254)

oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm (59,492,344 bytes) (cksum - 3293107452)

*Instant Client Package - SQL*Plus: Additional libraries and executable for running SQL*Plus with Instant Client

instantclient-sqlplus-linux.x64-11.2.0.3.0.zip (837,574 bytes) (cksum - 3996754029)

oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64.rpm (831,586 bytes) (cksum - 2150224972)

instantclient-sdk-linux.x64-11.2.0.3.0.zip (641,586 bytes) (cksum - 1205517808)

oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm (609,139 bytes) (cksum - 2701969031)

zip 或者 rpm 包选择一种，系统是centos，天生兼容RHEL，所以选择rpm格式的。

以64位为例，下载以下几个文件：

oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm

oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64.rpm

oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm

下载完以后装上。 rpm -Uhv

[root@mpaydb tmp]# rm -f oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm

ll -h
