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
