然后再create package body,在package body里面编写procedure的代码即可(相当于create procedure)。
包里没有create procedure
示例如下:
CREATE OR REPLACE PACKAGE pkg_test IS
PROCEDURE pro_test(V_OLD IN VARCHAR2,V_NEW IN VARCHAR2);
...
END test;
/
CREATE OR REPLACE PACKAGE BODY pkg_test IS
...
PROCEDURE pro_test(V_OLD IN VARCHAR2,V_NEW IN VARCHAR2) IS
BEGIN
...
END;
...
END pkg_test;
--创建包头
CREATE OR REPLACE PACKAGE ELS.pkg_proxy

1.配置hostname
[root@oracledb ~]#hostnamectl set-hostname oracledb
[root@oracledb ~]#echo " 10.100.1.10 oracledb" /etc/hosts
2.关闭selinux和防火墙
[root@oracledb ~]#sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
[root@oracledb ~]#setenforce 0
[root@oracledb ~]#systemctl stop firewalld
[root@oracledb ~]#systemctl disable firewalld
[root@oracledb ~]#systemctl status firewalld
3.下载Oracle软件包 且上传到服务器上,进行解压缩
建议使用winSCP工具进行上传到服务器的/opt目录下
[root@oracledb ~]# ls -lh /opt/
-rw-r--r-- 1 root root 1.2G Mar 30 16:12 linux.x64_11gR2_database_1of2.zip
-rw-r--r-- 1 root root 1.1G Mar 30 16:11 linux.x64_11gR2_database_2of2.zip
4.安装oracle环境所需要的依赖包-配置YUM源
安装依赖包之前,一定要设置好服务器上的安装源,原因是:可以在没有互联网的时候安装服务所需依赖包;常用的安装源有两种方式:
(1) 配置本地yum源
新建配置文件vi /etc/yum.repos.d/localsource.repo输入如下内容:
[localsource]
name=localsource
baseurl=
enabled=1
gpgcheck=0
(2) 生成本地yum 缓存
注意:从Oracle 11g 11.2.0.2版本开始,在Linux x86_64上安装时,只需要安装64位的软件包,但是,对于11.2.0.2之前的任何Oracle database 11g,下表中列出的32位和64位的安装包都必须安装
5.安装oracle环境所需要的依赖包-安装依赖包
(1)安装依赖包
[root@oracledb ~]# yum -y install binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel zlib zlib-devel pcre-devel unzip
(2)安装完成后,检查依赖是否全部安装成功
[root@oracledb ~]# rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel zlib zlib-devel pcre-devel unzip | grep "not installed"
(3)创建所需的用户组和用户
如果要安装Oracle数据库,通常需要以下本地操作系统用户组和用户:
Oracle inventory组(通常为 oinstall)
OSDBA组 (通常为 dba)
OSOPER组 (通常为 oper)
Oracle软件所有者(通常为 oracle)
创建用户组和用户:
[root@oracledb ~]# groupadd oinstall
[root@oracledb ~]# groupadd dba
[root@oracledb ~]# groupadd oper
[root@oracledb ~]# useradd -g oinstall -G dba oracle
(4)修改oracle用户密码:建议密码配置为字符+数字+特殊字符
[root@oracledb ~]# passwd oracle
6.配置内核参数和资源限制
(1)编辑配置文件vi /etc/sysctl.conf添加如下参数:
vm.max_map_count = 655360
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 2147483648 ###最小值: 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
注意:如果系统中某个参数高于上面的参数的值 ,保留较大的值,上面的数值只是官方要求的最小值,可以根据系统调整数值,以优化系统性能
(2)使内核参数生效
[root@oracledb ~]# sysctl -p
7.创建oracle安装目录
如下目录,根据自己的实际情况可做修改:
[root@oracledb ~]# mkdir -p /data/app/oracle/product/11.2.0
[root@oracledb ~]# cd /data/app/oracle/
[root@oracledb oracle]# mkdir oradata inventory fast_recovery_area
[root@oracledb ~]# chown -R oracle:oinstall /data/app/oracle
[root@oracledb ~]# chmod -R 775 /data/app/oracle
8.配置oracle用户环境变量
编辑配置文件vi /home/oracle/.bash_profile添加如下内容:
export ORACLE_BASE=/data/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0
export ORACLE_SID=orcl
export PATH=$PATH:$ORACLE_HOME/bin
9. 解压下载好的两个Oracle数据库文件
[root@oracledb ~]# cd /opt
[root@oracledb ~]# unzip linux.x64_11gR2_database_1of2.zip -d /data
[root@oracledb ~]# unzip linux.x64_11gR2_database_2of2.zip -d /data
10. 编辑静默安装响应文件
(1)切换到oracle用户执行
[root@oracledb ~]# su - oracle
(2)切换到响应文件的目录下
[oracle@oracledb ~]$ cp -R /data/database/response/ .
[oracle@oracledb ~]$ cd response/
[oracle@oracledb response]$ ls
dbca.rsp db_install.rsp netca.rsp
11.修改配置文件:vi /home/oracle/response/db_install.rsp,修改以下变量的值
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/data/app/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOME=/data/app/oracle/product/11.2.0
ORACLE_BASE=/data/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba
DECLINE_SECURITY_UPDATES=true
12. 开始静默安装Oracle 11g
(1)开始安装oracle数据库
[oracle@oracledb ~]$ cd /data/database
[oracle@oracledb ~]$ ./runInstaller -silent -responseFile /home/oracle/response/db_install.rsp -ignorePrereq
注意:安装期间可以使用tail命令查看oracle的安装日志,且日志文件名称是根
据自己的实际执行时间确定的,安装日志文件会在安装时提示,需要等待3分钟左右,注意不要停止运行;安装完成后有如下提示,如果有类似如下提示,说明安装完成。
The following configuration scripts need to be executed as the "root" user.
#!/bin/sh
#Root scripts to run
/data/app/oraInventory/orainstRoot.sh
/data/app/oracle/product/11.2.0/db_1/root.sh
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts
4. Return to this window and hit "Enter" key to continue
Successfully Setup Software.
13.使用 root用户执行脚本
(1)切换到root用户执行
[root@oracledb ~]# su - root
(2)执行两个用户脚本
[root@oracledb ~]# sh /data/app/oracle/inventory/orainstRoot.sh
[root@oracledb ~]# sh /data/app/oracle/product/11.2.0/root.sh
14.配置监听程序
(1)切换到oracle用户执行(建议退出重进oracle用户)
[root@oracledb ~]# su - oracle
(2)配置监听,查看输出结果
[oracle@oracledb ~]$ netca /silent /responsefile /home/oracle/response/netca.rsp
(3)查看监听服务状态,若没启动需要启动
[oracle@oracledb ~]$ lsnrctl status
[oracle@oracledb ~]$ lsnrctl start
查看结果:
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /data/etc/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Profile configuration complete.
Oracle Net Listener Startup:
Running Listener Control:
/data/app/oracle/product/11.2.0/bin/lsnrctl start LISTENER
Listener Control complete.
Listener started successfully.
Listener configuration complete.
Oracle Net Services configuration successful. The exit code is 0
(4)查看监听端口
[oracle@oracledb ~]$ netstat -tnpl | grep 1521
15.静默创建数据库
GDBNAME = "orcl"
SID = "orcl"
SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
DATAFILEDESTINATION =/data/app/oracle/oradata
RECOVERYAREADESTINATION=/data/app/oracle/fast_recovery_area
CHARACTERSET = "ZHS16GBK"
TOTALMEMORY = " 6552 "
##其中TOTALMEMORY = " 6552 " 为6552 MB,物理内存8G*80%
(2)切换到oracle用户执行
[root@oracledb ~]# su - oracle
(3)执行静默建库
[oracle@oracledb ~]$ dbca -silent -responseFile /home/oracle/response/dbca.rsp
执行过程如下:
Copying database files
1% complete
3% complete
11% complete
18% complete
26% complete
37% complete
Creating and starting Oracle instance
40% complete
45% complete
50% complete
55% complete
56% complete
60% complete
62% complete
Completing Database Creation
66% complete
70% complete
73% complete
85% complete
96% complete
100% complete
Look at the log file "/data/app/oracle/cfgtoollogs/dbca/orcl/orcl.log" for further details.
(4)查看进程
[oracle@oracledb ~]$ ps -ef | grep ora_ | grep -v grep
(5)再次查看监听状态进行确认
[oracle@oracledb ~]$ lsnrctl status
结果显示:
The command completed successfully
16.至此数据库就安装成功了,下面我们登录下数据库
(1)切换到oracle用户执行
[root@oracledb ~]# su - oracle
(2)登录数据库
[oracle@oracledb ~]$ sqlplus / as sysdba
(3)查询实例状态
SQLselect status from v$instance;
(4)查看数据库版本
SQL select * from v$version;
(5)激活scott用户
SQLalter user scott account unlock;
SQLalter user scott identified by tiger;
SQLselect username,account_status from dba_users;
17.设置Oracle开机启动
(1)修改配置文件vi /data/app/oracle/product/11.2.0/bin/dbstart 修改如下内容:
将脚本中的ORACLE_HOME_LISTNER=$1,修改为ORACLE_HOME_LISTNER=$ORACLE_HOME
(2)修改配置文件vi /data/app/oracle/product/11.2.0/bin/dbshut 修改如下内容:
将脚本中的ORACLE_HOME_LISTNER=$1,修改为ORACLE_HOME_LISTNER=$ORACLE_HOME
(3)修改配置文件 vi /etc/oratab修改如下内容,
orcl:/data/app/oracle/product/11.2.0:Y
(4)新建文件:vi /etc/rc.d/init.d/oracle 注意:建议全部复制脚本内容
#! /bin/bash
# oracle: Start/Stop Oracle Database 11g R2
# chkconfig: 345 90 10
# description: The Oracle Database is an Object-Relational Database Management System.
# processname: oracle
. /etc/rc.d/init.d/functions
LOCKFILE=/var/lock/subsys/oracle
ORACLE_HOME=/data/app/oracle/product/11.2.0
ORACLE_USER=oracle
case "$1" in
start)
if [ -f $LOCKFILE ]; then
echo $0 already running.
exit 1
fi
echo -n #34;Starting Oracle Database:"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl start"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl start dbconsole"
touch $LOCKFILE
;;
stop)
if [ ! -f $LOCKFILE ]; then
echo $0 already stopping.
exit 1
fi
echo -n #34;Stopping Oracle Database:"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl stop"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbshut"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl stop dbconsole"
rm -f $LOCKFILE
;;
restart)
$0 stop
$0 start
;;
status)
if [ -f $LOCKFILE ]; then
echo $0 started.
else
echo $0 stopped.
fi
;;
*)
echo "Usage: $0 [start|stop|status]"
exit 1
esac
exit 0
(5)给 /etc/init.d/oracle添加执行权限
[root@oracledb ~]# chmod +x /etc/init.d/oracle
(6)开机启动oracle
[root@oracledb ~]# chkconfig oracle on
(7)给启动文件加权限
[root@oracledb ~]# cd /data/app/oracle/product/11.2.0/bin/
[root@oracledb bin]# chmod 6751 oracle
[root@oracledb bin]# cd /var/tmp
[root@oracledb tmp]# chown -R oracle:oinstall .oracle
(8)重启测试
[root@oracledb ~]# reboot
(9)切换到oracle用户登录状态下
[root@oracledb ~]# su - oracle
[oracle@oracledb ~]$ sqlplus / as sysdba
(10)解除锁定
SQL alter user SYSTEM account unlock;
(11)这时候就可以用Navicat连接了
SQL conn;
用户名:SYSTEM
密码:oracle
如果不能正确连接,改下密码试试
alter user system identified by 新密码
[root@oracledb ~]# mkdir -p /data/szzt
[root@oracledb ~]# cd /data/
[root@oracledb data]# chown oracle:oinstall -R szzt
[root@oracledb data]# ll
total 0
drwxr-xr-x 3 root root 20 Apr 8 21:14 app
drwxr-xr-x 8 root root 128 Aug 21 2009 database
drwxr-xr-x 2 oracle oinstall 6 Apr 14 16:17 szzt
[root@oracledb ~]# su - oracle
[oracle@oracledb ~]$ sqlplus / as sysdba
SQL conn cshi
Enter password: 登录失败
Connected.
SQL create temporary tablespace DB_DATA_TMP tempfile'/data/szzt/DB_DATA_TMP.dbf' size 500m autoextend on next 100m maxsize 10240m extent management local;
显示结果:
Tablespace created.
SQL create tablespace DB_DATA logging datafile'/data/szzt/DB_DATA.dbf' size 2048m autoextend on next 100m maxsize 10240m extent management local;
显示结果:

SQL grant dba to ceshi;
显示结果:
Grant succeeded.
SQL conn ceshi ###用户名和密码一样,此时登录成功
[oracle@oracledb ~]$ cd /data/app/oracle/product/11.2.0/bin/
注意:数据库导出操作是在 源服务器 上进行
[oracle@oracledb bin]$ exp 用户名/密码@ IP地址 /orcl file =/data/szzt/ceshi.dmp owner='用户名'
Export terminated successfully without warnings.
注意:数据库导入操作是在 目标服务器 上进行
[oracle@oracledb bin]$ imp ceshi/ceshi@ 10.100.1.10 /orcl file=/data/szzt/ceshi.dmp fromuser=ceshi touser=ceshi
显示结果:可以看到导入的表过程(10.100.1.10是自己的目标数据库服务器)
Import terminated successfully without warnings .
(1)、数据导入完毕后,我们可以使用DBeaver对数据库进行远程管理
(2)、测试连接,没问题后完成新建
(3)、连接上来后,我们就可以使用工具来进行管理数据库
请说明您所谓的排名是怎么排名的 是按工号还是按工资排名???
IC介绍
许多人正在使用Oracle Instant Client,它提供一个部署基于OCI、OCCI、JDBC OCI应用容易和快速的方法。
通过添加更多的工具,Instant Client可以变成一个更加强大的工具,如下:
1. tnsping
2. sqlldr
3. tkprf
4. exp/imp
5. OCM
6. 你自己的工具
这样做的主要优点是:
1. 安装是一件轻而易举的事情,只要解压即可完成。
2. 体积小,未压缩100MB到150MB或压缩50MB,它可以安装在USB盘上
3. 不涉及到SA(软件架构)
比较一个完整的Oracle安装需要大量的磁盘空间,而且还涉及到SA。
IC需求
1. 一个带有150MB+磁盘空间的Unix/Linux账号:
hadoop@192.168.8.162:/home/hadoop/oracle
2. 安装Oracle 11gR2的相同平台,一个具有读访问权限的账号:
root@192.168.8.192:/u01/product/oracle/11.2.0/db_1
IC安装
从Oracle官方网址下载安装包,
注:请根据操作系统版本下载相应的安装包,这里下载Linux X86-64安装包。
instantclient-basic-linux.x64-11.2.0.4.0.zip
instantclient-jdbc-linux.x64-11.2.0.4.0.zip
instantclient-sdk-linux.x64-11.2.0.4.0.zip
instantclient-sqlplus-linux.x64-11.2.0.4.0.zip
注:下载Instant Client时需要创建一个Oracle账号才能下载。
使用SSH客户端使用安装账号登录到服务器,在根目录下创建一个oracle目录:
$mkdir /home/hadoop/oracle
上传所有压缩包或至少basic和sqlplus两个包到你账号的根目录下oracle中。
解压到当前目录下完成安装。
$ cd /home/hadoop/oracle
$ unzipinstantclient-basic-linux.x64-11.2.0.4.0.zip
$ unzipinstantclient-sqlplus-linux.x64-11.2.0.4.0.zip
$ unzip instantclient-sdk-linux.x64-11.2.0.4.0.zip
$ unzip instantclient-jdbc-linux.x64-11.2.0.4.0.zip
解压完毕后会在当前目录下生成一个instantclient_11_2目录。
$ ll /home/hadoop/oracle/instantclient_11_2
IC配置
配置下面的环境变量到你的Shell配置文件中。
$ vi ~/.bashrc
跳到文件的末尾,添加下面这些环境变量:
export RACLE_IC_HOME=/home/hadoop/oracle/instantclient_11_2
exportORACLE_HOME=$ORACLE_IC_HOME
exportTNS_ADMIN=$ORACLE_IC_HOME
exportPATH=$PATH:$ORACLE_IC_HOME
exportLD_LIBRARY_PATH=$ORACLE_IC_HOME
exportCLASSPATH=$ORACLE_IC_HOME/ojdbc6.jar:./
$ source ~/. bashrc
或 $ . ~/.bashrc
注:如果需要让所有用户都能使用,需要把上面的配置添加/etc/profile中。
在$ORACLE_IC_HOME目录下创建一个tnsnames.ora文件:
$ vi /home/hadoop/oracle/instantclient_11_2/tnsnames.ora
orcl=(description=(address=(protocol=tcp)(host=192.168.8.161)(port=1521))(connect_data=(server=dedicated)(service_name=wcdma)))
或
ora =(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = 192.168.8.161)(PORT = 1521)))(CONNECT_DATA =(SERVER =DEDICATED)(SERVICE_NAME = wcdma)))
SQL*Plus
$ sqlplus kqi/kqi@192.168.8.161:1521/wcdma
或
$ sqlplus kqi/kqi@orcl
SQL*Plus: Release 11.2.0.4.0 Production onThu Nov 20 14:01:49 2014
Copyright (c) 1982, 2013, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise EditionRelease 11.2.0.2.0 - 64bit Production
With the Partitioning, OLAP, Data Miningand Real Application Testing options
SQL
ERROR:
ORA-12154: TNS:could not resolve theconnect identifier specified
对于这种问题,排除添加的配置格式错误后。可能原因是读取的tnsnames.ora路径根本就不是$ORACLE_HOME/network/admin下。
注:tnsnames.ora文件的查找路径顺序为:
$HOME = $TNS_ADMIN = /etc =$ORACLE_HOME/network/admin/。
现在我们已经有一个构建自己的Instant Client包的基础了。下面是Instant Client的核心文件(位于/home/hadoop/oracle/instantclient_11_2中):
1. libclntsh.so.11.1:客户端代码库
2. libociei.so:OCI InstantClient数据共享库
3. libnnz11.so:安全库
4. libocci.so.11.1:Oracle C++调用接口库
5. libocijdbc11.so:JDBC OCI库
6. ojdbc6/5.jar:JDBC驱动(OCI和Thin)
7. orai18n.jar:字符集转换和本地支持库
Tnsping
从安装Oracle的服务器上拷贝tnsping过来,执行命令:
$ cd /home/hadoop/oracle/instantclient_11_2
$ scp root@192.168.8.192:/u01/product/oracle/11.2.0/db_1/bin/tnsping./
现在让在IC安装服务器上尝试运行下它:
$ tnsping ora

运行后tnsping抱怨一些文件丢失,更具体的说一个消息文件丢失。现在,我们把该文件从Oracle安装服务器上拷贝过来,进入到instantclient_11_2目录:
$ mkdir -p network/mesg
$ cd network/mesg/
现在从安装Oracle服务上拷贝tnsus.msb文件到该目录中:
$ scp root@192.168.8.192:/u01/product/oracle/11.2.0/db_1/network/mesg/tnsus.msb ./
让我们再尝试一次tnsping,结果如下:
$ tnsping ora

Sqlldr
本节将添加另外一个工具sqlldr。
首先,我们从安装Oracle的服务器上拷贝sqlldr到IC安装目录instantclient_11_2下。
$ cd /home/hadoop/oracle/instantclient_11_2
$ scproot@192.168.8.192:/u01/product/oracle/11.2.0/db_1/bin/sqlldr ./
尝试运行它:
$ sqlldr
Message 2100 not found; No message file forproduct=RDBMS, facility=ULMessage 2100 not found; No message file forproduct=RDBMS, facility=UL
首先我们需要在instantclient_11_2下创建rdbms/mesg目录。
$ cd /home/hadoop/oracle/instantclient_11_2
$ mkdir -p rdbms/mesg
$ cd rdbms/mesg
把ORACLE安装目录下rdmsb/mesg/ulus.msb拷贝到当前目录。
$ scp root@192.168.8.192:/u01/product/oracle/11.2.0/db_1/rdbms/mesg/ulus.msb./
现在,让我们再次尝试运行它。
$ sqlldr

Usage: SQLLDR keyword=value[,keyword=value,...]
Valid Keywords:
Exp/imp
从安装Oracle服务器上拷贝二进制文件过来。
$ cd /home/hadoop/oracle/instantclient_11_2
$ scp root@192.168.8.192:/u01/product/oracle/11.2.0/db_1/bin/imp ./
$ scp root@192.168.8.192:/u01/product/oracle/11.2.0/db_1/bin/exp ./
尝试运行imp和exp,结果如下:
$ imp
Message 100 not found; No message file forproduct=RDBMS, facility=IMP: Release 11.2.0.4.0 - Production on Thu Nov 2017:02:57 2014

Export terminated unsuccessfully
EXP-00000: Message 0 not found; No messagefile for product=RDBMS, facility=EXP
再从安装Oracle服务器上拷贝rdbms/mesg下的expus.msb和ipus.msb过来。
$ cd rdbms/mesg/
$ scproot@192.168.8.192:/u01/product/oracle/11.2.0/db_1/rdbms/mesg/impus.msb ./
$ scproot@192.168.8.192:/u01/product/oracle/11.2.0/db_1/rdbms/mesg/expus.msb ./
再次运行imp/exp工具错误提示消失,可以正常运行。
Tkprof
现在我们继续添加我最喜欢的工具tkprof。
从安装Oracle的服务器拷贝tkprof到instantclient_11_2目录下。
$ cd /home/hadoop/oracle/instantclient_11_2
$ scp root@192.168.8.192:/u01/product/oracle/11.2.0/db_1/bin/tkprof ./
$ mkdir -p oracore/mesg/
$ cd oracore/mesg/
$ scproot@192.168.8.192:/u01/product/oracle/11.2.0/db_1/oracore/mesg/lrmus.msb ./
使用示例:
$ tkprof test.trc test.out
Instant Client Bundle
现在,我们已经让所有工具都能正常工作。简单的使用工具压缩打包instantclient_11_2目录,这样你就获得你自己的Instant Client包。例如:
$ cd /home/hadoop/oracle
$ tar zcf instantclient_11_2.tar.gzintantclient_11_2
正如你所看到的,打包成的instant client带有tnsping,sqlldr, exp/imp,tkprof工具,这让IC更加的功能强大。
安装自定义的IC包步骤如下:
1. 上传到服务器上解压缩
2. 修改环境变量
$ vi ~/.bashrc
跳到文件的末尾,添加下面这些环境变量:
export ORACLE_IC_HOME=解压目录/instantclient_11_2
export ORACLE_HOME=$ORACLE_IC_HOME
export TNS_ADMIN=$ORACLE_IC_HOME
export PATH=$PATH:$ORACLE_IC_HOME
export LD_LIBRARY_PATH=$ORACLE_IC_HOME
exportCLASSPATH=$ORACLE_IC_HOME/ojdbc6.jar:./
$ source ~/. bashrc
或 $ . ~/.bashrc
3. 添加连接数据库的配置
$ vi $ORACLE_IC_HOME/tnsnames.ora
安装完成,现在就可以使用Instant Client中的工具啦!
