在linux下卸载oracle软件比较简单，可以简单的把相关目录删除掉，然后清理一下/etc下oracle相关的文件就可以。
但还是有必要了解一下如何通过工具来卸载。
1、首先配置响应文件
如下是一个响应文件例子：
[root@suk1 response]# more uninstall.rsp
#-------------------------------------------
#响应文件的版本
RESPONSEFILE_VERSION=2.2.1.0.0
#oracle用户组
UNIX_GROUP_NAME=oinstall
#ORACLE_HOME的完整路径
ORACLE_HOME="/opt/oracle/product/10g"
#ORACLE_HOME名称
ORACLE_HOME_NAME="OraDb10g_home1"
DEINSTALL_LIST={"oracle.server","10.2.0.1.0"}
#设置dba组名
s_nameForDBAGrp=oinstall
#设置oper组名
s_nameForOPERGrp=oinstal
#--------------------------------------------
以上参数根据实际情况休修改。
2、在oracle用户下卸载
[oracle@suk1 database]$ ./runInstaller -silent -deinstall -removeallfiles -removeAllPatches "REMOVE_HOMES={$ORACLE_HOME}" -responseFile /soft/database/response/uninstall.rsp

命令执行完后，oracle会把oracle_home和/usr/bin下的相关文件都删除。
步骤很简单，这里也简单记录一下。
