Oracle Instant Client Downloads

文章内容均已64位版本为例，如果客户端有特殊需求请使用32位版本兼容

  1. Linux Oracle Instant Client推荐使用RPM方式安装，如果需要定制具体路径可以使用zip包手动配置
  2. Windows和Linux类似但需要主要PATH环境变量的配置
  3. 实测12版本客户端可以向下兼容11版本的数据库服务器，Oracle Instant Client 12.2.0.1.0，Oracle Database 11.2.0.3.0

Linux

以RPM最简方式为例

Preparation

Download all the required RPM from the official site and put them on the target system.
Current RPMs for 64bit are:
oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm
oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm

Install RPMs

# install as root
rpm -ivh oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm

# create oracle group and user
groupadd dba 
useradd -g dba oracle
echo oracle:oracle | chpasswd

# configure profile
su - oracle
vi ~/.bash_profile 

export LD_LIBRARY_PATH=/usr/lib/oracle/12.2/client64/lib
export TNS_ADMIN=/usr/lib/oracle/12.2/client64/
export PATH=/usr/lib/oracle/12.2/client64/bin:$PATH

# Connect to Your database with:
sqlplus system/oracle@oracapdb

# create new tnsnames.ora
# ORA-12154: TNS:could not resolve the connect identifier specified
vim /usr/lib/oracle/12.2/client64/tnsnames.ora

oracapdb =
   (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.28.70.244)(PORT = 1521))
          (CONNECT_DATA =
        (SERVER = DEDICATED)
      (SERVICE_NAME = oracapdb)
   )
)

# You can also use the Easy Connect connection string format (does not use TNSNAMES):
sqlplus system/oracle@//172.28.70.244:1521/oracapdb

Windows

Windows的配置相比Linux差不多简单，注意环境变量尤其是TNS_ADMIN
