SID: error while loading shared libraries: libodm9.so: cannot open shared object file: No such file or directory
ERROR:
ORA-12547: TNS:lost contact

在$ORACLE_HOME/lib下发现libodm9.so存在。这可能是安装过程中oracle link有问题.
$ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk install
$ORACLE_HOME/bin relink all

在执行过程中，有时会发生错误： hidden symbol `__fixunssfdi' in /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/libgcc.a(_fixunssfdi.oS) is referenced by DSO

这是由于gcc，g++不再指向296 version.
重建这些link
/usr/bin
ln -s gcc296 gcc
ln -s g++296 g++
重新执行，OK
