现象:
出现这种问题,是因为/etc/oratab 中没有实例的信息,这里手工按固定格式添加,在重新运行GUI即可。
[oracle@dave oradata]$ cat /etc/oratab # # This file is used by ORACLE utilities. It is created by root.sh # and updated by either Database Configuration Assistant while creating # a database or ASM Configuration Assistant while creating ASM instance. # 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 $ORACLE_SID are not allowed. # dave:/u01/app/oracle/product/11.2.0/db_1:Y [oracle@dave oradata]$
