解决方法：
[root@aix215 tmp]# cat /etc/oratab
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
# Multiple entries with the same $ORACLE_SID are not allowed.

[root@aix215 tmp]#
删除文件中的：
prod:/u01/app/oracle/product/10.2.0/db_1:N
prod1:/u01/app/oracle/product/10.2.0/db_1:N
问题依旧，没能解决！
删除/etc/oratab 文件：
[root@aix215 rootpre]# ls /etc/ |grep -i ora
oraInst.loc
ora_save_14-05-09.11:36:18
oracle
oratab
[root@aix215 rootpre]# rm -rf /etc/ora_save_14-05-09.11:36:18
[root@aix215 rootpre]# rm -rf /etc/oracle
[root@aix215 rootpre]# rm -rf /etc/oratab
问题解决：（执行‘next’成功）
@至此，问题解决，原因应该是，没有彻底清除以前遗留的CRS安装信息！
