Oracle-11g開機自啟

1.修改/etc/oratab 檔案

在root 賬戶下修改/etc/oratab 檔案最後的N 改為Y

[root@trade-db-test ~]# 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.
#

2.修改啟動腳本 dbstart

在 oracle 賬戶下修改 ORACLE 自帶的啟動腳本 dbstart

dbstart 找到 ORACLE_HOME_LISTNER=$1 這一行 <84行>
修改為：ORACLE_HOME_LISTNER=$ORACLE_HOME

[root@trade-db-test ~]# su - oracle

###################################
# 
# usage: dbstart $ORACLE_HOME
#
# This script is used to start ORACLE from /etc/rc(.local).
# It should ONLY be executed as part of the system boot procedure.
#
# This script will start all databases listed in the oratab file
# whose third field is a "Y".  If the third field is set to "Y" and
# there is no ORACLE_SID for an entry (the first field is a *),
# then this script will ignore that entry.
#
# This script requires that ASM ORACLE_SID's start with a +, and 
# that non-ASM instance ORACLE_SID's do not start with a +.
#
# If ASM instances are to be started with this script, it cannot
# be used inside an rc*.d directory, and should be invoked from
# rc.local only. Otherwise, the CSS service may not be available
# yet, and this script will block init from completing the boot
# cycle.
#
# If you want dbstart to auto-start a single-instance database that uses
# an ASM server that is auto-started by CRS (this is the default behavior
# for an ASM cluster), you must change the database's ORATAB entry to use
# a third field of "W" and the ASM's ORATAB entry to use a third field of "N".
# These values specify that dbstart auto-starts the database only after
# the ASM instance is up and running.
#
# Note:
# Use ORACLE_TRACE=T for tracing this script.
#
# The progress log for each instance bringup plus Error and Warning message[s]
# are logged in file $ORACLE_HOME/startup.log. The error messages related to 
# instance bringup are also logged to syslog (system log module).
# The Listener log is located at $ORACLE_HOME_LISTNER/listener.log
# 
# On all UNIX platforms except SOLARIS
# ORATAB=/etc/oratab
#
# To configure, update ORATAB with Instances that need to be started up
#    Entries are of the form:
#    $ORACLE_SID:$ORACLE_HOME:<N|Y|W>:
#    An example entry:
#    main:/usr/lib/oracle/emagent_10g:Y
#
# Overall algorithm:
# 1) Bring up all ASM instances with 'Y' entry in status field in oratab entry
# 2) Bring up all Database instances with 'Y' entry in status field in
#    oratab entry
# 3) If there are Database instances with 'W' entry in status field
#    then
#      iterate over all ASM instances (irrespective of 'Y' or 'N') AND
#      wait for all of them to be started
#    fi
# 4) Bring up all Database instances with 'W' entry in status field in
#    oratab entry
