環境:centos 6.5 + oracle 11g

自啟動之前問題

虛擬機里的oracle環境，每次重啟完系統，用plsql developer連接，先是報錯:

無TNS監聽程序

解決方法是切換到系統的oracle用戶，執行lsnrctl start，但是執行之前，因為ORACLE_HOME環境變量沒有生效，還要是環境變量文件生效，步驟如下:

[oracle@localhost ~]$source .bash_profile

[oracle@localhost ~]$echo $ORACLE_HOME

/home/oracle/app/oracle/product/11.2.0/dbhome_1

[oracle@localhost ~]$lsnrctl start

啟動完成后，再次連接，又報錯:

oracle沒有啟動。啟動步驟如下:

[oracle@localhost ~]$ sqlplus /nolog

配置自啟動

下面把上述過程都配置成開機啟動。

環境變量生效

可能是因為我的oracle用戶不是桌面登錄的，是從終端su切換過來的，.bash_profile文件沒有運行。我把文件里的內容寫入.bashrc文件后，重啟就可以了。

TNS監聽以及oracle服務自啟動

編輯: /etc/oratab文件，把最后一行的N改成Y

# 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:/home/oracle/app/product/11.2.0/dbhome_1:Y

路徑可能不同

編輯 /etc/rc.local 文件,增加 最后兩行:

#!/bin/sh

#

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

service smb restart

su - oracle -c 'lsnrctl start'

su - oracle -c 'dbstart'

su - oracle -c 'emctl start dbconsole'

dbstart是數據庫自帶的啟動腳本，我們只要加到rc.local中讓它開機調用就可以了。但是還需要編輯一下它。修改dbstart的ORACLE_HOME_LISTNER，使其指向$ORACLE_HOME:

# First argument is used to bring up OracleNet Listener

ORACLE_HOME_LISTNER=$ORACLE_HOME

重啟虛擬機，發現plsql developer可以直接連接上了。
