安装完成oracle 9.2.0.4之后，执行sqlplus 命令时遇到Segmentation Fault 错误，
查询 Metalink 是一个bug:Segmentation Fault When Execute Sqlplus, Oracle, Lsnrctl After New/Patchset Install [ID 316746.1]
对于新安装的软件或者打过补丁的oracle数据库(9.2.0.1 to 10.1.0.2，for Linux x86,Linux x86-64)都可能遇到此bug
原因是：
The gcc/g++ compilers in /usr/bin are a script. (with additional parameters)which caused an incorrect compilation.
make.log shows this incorrect compilation:
/tpp/oracle/920/bin/genclntsh
/usr/bin/ld: skipping incompatible /usr/lib/gcc-lib/i386-redhat-linux/2.96/libgcc.a when
searching for -lgcc
/usr/bin/ld: skipping incompatible /usr/lib/gcc-lib/i386-redhat-linux/2.96/libgcc.a when
searching for -lgcc
/usr/bin/ld: warning: i386 architecture of input file
`/usr/lib/gcc-lib/i386-redhat-linux/2.96/crtbeginS.o' is incompatible with i386:x86-64 output
/usr/bin/ld: warning: i386 architecture of input file
`/usr/lib/gcc-lib/i386-redhat-linux/2.96/crtendS.o' is incompatible with i386:x86-64 output.
解决办法：
1. cd /usr/bin (as root)
2. mv gcc gcc.script
3. mv g++ g++.script
4. ln -s gcc32 gcc
5. ln -s g++32 g++
6. login as oracle software owner (make sure environment is correct)
7. cd $ORACLE_HOME/bin
8. relink all
我的步骤如下：
以root用户做如下操作：
root@rac1:/opt/oracle/products/9.2.0#cd /usr/bin
root@rac1:/usr/bin#mv gcc gcc.sript
root@rac1:/usr/bin#mv gcc.sript gcc.script
root@rac1:/usr/bin#mv g++ g++.script
root@rac1:/usr/bin#ln -s gcc32 gcc
root@rac1:/usr/bin#ln -s g++32 g++
以oracle用户
oracle@rac1:/home/oracle>cd $ORACLE_HOME/bin
oracle@rac1:/opt/oracle/products/9.2.0/bin>relink all
