# 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::
#
# 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.
#

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

最后的N或者Y表示是否允许dbstart来启动数据库,如果为N则实例不能通过dbstart启动,表现为sqlplus连接实例时显示Connected to an idle instance.如果为Y则实例可以通过dbstart启动,sqlplus连接后数据库即为open状态。
