4.3, package requirements

This is the most annoying. Countless people are dying on this or energy is spent on it.
But 11g is very user-friendly, adding the mechanism for checking, and there is no need to install a lot of 32-bit packages under 64-bit like 10g, just install A gcc-32bit-4.3 is OK. The following list must be installed:

binutils-2.20.51.0.2-5.11.el6 (x86_64)compat-libcap1-1.10-1 (x86_64)compat-libstdc++-33-3.2.3-69.el6 ( X86_64)compat-libstdc++-33-3.2.3-69.el6.i686gcc-4.4.4-13.el6 (x86_64)gcc-c++-4.4.4-13.el6 (x86_64)glibc-2.12-1.7.el6 ( I686) glibc-2.12-1.7.el6 (x86_64) glibc-devel-2.12-1.7.el6 (x86_64) glibc-devel-2.12-1.7.el6.i686kshlibgcc-4.4.4-13.el6 (i686) libgcc-4.4. 4-13.el6 (x86_64)libstdc++-4.4.4-13.el6 (x86_64)libstdc++-4.4.4-13.el6.i686libstdc++-devel-4.4.4-13.el6 (x86_64)libstdc++-devel-4.4. 4-13.el6.i686libaio-0.3.107-10.el6 (x86_64)libaio-0.3.107-10.el6.i686libaio-devel-0.3.107-10.el6 (x86_64)libaio-devel-0.3.107- 10.el6.i686make-3.81-19.el6sysstat-9.0.4-11.el6 (x86_64)

Tip (do not add the version number to the package name, that is, the first "-number" , such as gcc)

rpm -q package name yum list installed
