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.

prod1:/u01/app/oracle/product/10.2.0/db_1:N

[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！
