服务器1 os: AIX 5.3 ip: 192.168.0.1 db: Oracle 11gR2 服务器2： os: AIX IP: 192.168.0.5 db: DB2 v9.7 主要目的：通过在服务

服务器1

os: AIX 5.3

ip: 192.168.0.1

db: Oracle 11gR2

服务器2：

os: AIX

IP: 192.168.0.5

db: DB2 v9.7

主要目的：

通过在服务器1中构建透明网关，实现在oracle数据库中连接服务器2中的DB2数据库。

DB2数据库性能优化介绍

实施步骤：

1. 在服务器1中安装unixODBC驱动程序。

a) 在官方网站中下载unixODBC驱动源代码包：http:://www.unixodbc.org

b) 导入几个必要的环境变量：

export OBJECT_MODE=64 (确保编译出来的unixODBC为64位可执行程序，，假如数据库是32，那么64换成32)
export PATH=$PATH:/usr/vacpp/bin(这个是编译器安装地址)
export CC=xlc_r
export CCC=xlC_r

c) 进入解压够的unixODBC目录，解压后的目录如下图所示：

./configure --prefix=/usr/local/unixODBC
./make
./makeinstall

d) 在oracle的.profile中添加下面几行：

export ODBCHOME=/usr/local/unixODBC/etc
export ODBCINI=$ODBCHOME/odbc.ini
export PATH=$PATH:/usr/local/unixODBC/bin

export LD_LIBRARY_PATH=/usr/local/unixODBC/lib

e) 进入/usr/local/unixODBC/lib目录，执行下面这些命令：

ar -x-X any libodbc.a
ar -x-X any libodbccr.a
ar -x-X any libodbcinst.a

ln -slibodbc.so.2 libodbc.so
ln -slibodbccr.so.2 libodbccr.so
ln -slibodbcinst.so.2 libodbcinst.so
