Centos安装Oracle客户端

从这里”http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html”下载以下三个文件

instantclient-basic-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

新建并复制到Oracle文件夹下,自然解压后,会生成“instantclient_11_2”目录,basicsqlplus会在其根下,而sdk会在其下生成“sdk”目录;在其下建立目录“/network/admin”,创建文件:“tnsnames.ora”,并添加:

ORCL =

 (DESCRIPTION =

   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.232.1)(PORT = 1521))

   (CONNECT_DATA =

     (SERVER = DEDICATED)

     (SERVICE_NAME = orcl)

   )

 )

配置:”sudo gedit /etc/profile

export ORACLE_HOME=/root/instantclient_11_2

export PATH=$ORACLE_HOME:$PATH

export TNS_ADMIN=$ORACLE_HOME/network/admin

export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH

export NLS_LANG=’SIMPLIFIED CHINESE_CHINA.AL32UTF8′

 运行:“source /etc/profile”使之生效

执行:sqlplus /nolog

结果:

u@ubuntu:~$ sqlplus /nolog

Mac下安装cx_Oracle

经历了各种错误,都想放弃了,本打算最后再试试最后一种方法,安装mac下的python 32位版本,偶然间发现了下面的文章,一步一步照做(连安装cx_oracle都没有用yum,直接下载的源码),竟然成功了!!!Happy

Build and Install cx_Oracle on Mac Leopard Intel

I finally succeeded in building and installing cx_Oracle on a Mac. I will outline the steps that I took. There are many redundant steps that I may later take out. But there are checks that I made on the way that really helped.

The first Mac that I installed cx_Oracle was a 2.4 GHz Intel Core 2 Duo running Mac OSX 10.6.6. It had 4 GB of Memory. Most of my work was done on a terminal window.

Check Python Installation

The OSX comes with a Python interpreter. I ran a check to find the version number.

$ python -V
Python 2.6.1
This was sufficient for my needs. I decided not to upgrade to Python version 2.7.1
Xcode from Apple

The Xcode package is available from Apple Developer. You will need a login account but that is free. Now you do not need Xcode 4. Xcode 3 is sufficient because all we are interested in is the gcc compiler. After you login look for a link that says Looking for Xcode 3? I downloaded X code 3.2.6 and iOS SDK 4.3. It was 4.1 GB in size and is best done when you know you will not be using your Mac.

After the download, the installation went off smoothly. I restarted the Mac and on a terminal window checked that the gcc compiler was installed correctly.

$ which gcc
/usr/bin/gcc

$ gcc -v
gcc version 4.2.1
You can also do man gcc to get the online manual for gcc.
Install Oracle Instant Client

The cx_Oracle has a dependency. It needs Oracle Instant Client from Oracle. Click on the link Instant Client for Mac OS X (Intel x86). Accept the license agreement and download Version 10.2.0.4 (64-bit). I tried the 32-bit and it does NOT work. You will need your Oracle account to download the following packages:

instantclient-basic-10.2.0.4.0-macosx-x64.zip
instantclient-sdk-10.2.0.4.0-macosx-x64.zip
I created a directory called oracle to unpack the packages. The pathname on my machine was /Users/utcs/oracle. On your machine, it will be your user name instead of utcs. I moved both the basic and sdk packages into the oracle directory and unzipped them. After unzipping the basic package I got a folder instantclient_10_2.

After unzipping the sdk package, I got a folder called instantclient_10_2-1. Inside that folder was another folder called sdk. I moved the folder named sdk inside the folder instantclient_10_2.

From a terminal window I changed directory to sdk. On my machine, the full path name was /Users/utcs/oracle/instantclient_10_2/sdk. There is another .zip file called ottclasses.zip. I unzipped that as follows:

$ unzip ottclasses.zip
It produced a folder called oracle. I changed directory to /Users/utcs/oracle/instantclient_10_2. I ran the following command to copy all the files in the sdk folder.
$ cp -R ./sdk/* .
$ cp -R ./sdk/include/* .
The last two commands may not have been necessary. But it makes it easier to locate the header files.
Setting up the Environment Variables

In my home directory /Users/utcs I created a .profile file. Its content was as follows:

export ORACLE_HOME=/Users/utcs/oracle/instantclient_10_2
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME
Restart the machine. Open another terminal window and run the following commands to check that the environment variables have been set properly:
$ source .profile
$ echo $ORACLE_HOME
$ echo $DYLD_LIBRARY_PATH
$ echo $LD_LIBRARY_PATH
You should see the path names printed out correctly. I created two symbolic links in the $ORACLE_HOME directory (/Users/utcs/oracle/instantclient_10_2) as follows:
ln -s libclntsh.dylib.10.1 libclntsh.dylib
ln -s libocci.dylib.10.1 libocci.dylib
If you run the command ls -l in that directory you should see the symbolic links.
Building and Installing cx_Oracle

Download from SourceForge cx_Oracle version 5.0.4. You need to get the package that says Source Code only. In your Download folder you will find cx_Oracle-5.0.4.tar. I moved it to /Users/utcs/oracle. To untar, I used the following command:

tar -xvf cx_Oracle-5.0.4.tar
After untarring I had a subdirectory called cx_Oracle-5.0.4. In a terminal window I changed directory to /Users/utcs/oracle/cx_Oracle-5.0.4. I checked in that window that all the environment variables were set properly by doing

echo $ORACLE_HOME
echo $LD_LIBRARY_PATH
echo $DYLD_LIBRARY_PATH
which python
which gcc
I did not have administrative privileges on this Mac so to build I did
python setup.py build
I checked to output. There were many warning messages that I ignored. Even a single error message would have indicated that the build process did not succeed. I next installed cx_Oracle by
python setup.py install
The install also finished without any error messages.
Test the cx_Oracle installation

On a terminal window type python. It should bring up Python in interactive mode. Then type import cx_Oracle. It should add the package to your path without any errors. Get out of the interactive mode using Control-D.

Now copy and paste this script into a file called Check.py. Change the user name and run it on the command line.

import cx_Oracle, string, getpass

def main():
# Get password
pswd = getpass.getpass()

# Build connection string
user = “CS327_jdoe”
host = “oracle.microlab.cs.utexas.edu”
port = “1521”
sid = “orcl”
dsn = cx_Oracle.makedsn (host, port, sid)

# Connect to Oracle and test
con = cx_Oracle.connect (user, pswd, dsn)
if (con):
print “Connection successful”
print con.version
else:
print “Connection not successful”

con.close()

main()
You should see Connection successful if all the other tests were successful.
