本文通过使用python脚本来启动oracle数据库,实现oracle数据库的开机启动(主要启动监听和数据库,不包含dbconsole):

STEP1:关闭数据库,关闭监听


[oracle@REDHAT6 ~]$ lsnrctl stop

SQL> shutdown immediate

STEP2:查看是否有python相关的包是否已经安装(若没有安装,就需要安装相关的包)

[root@REDHAT6 ~]# which python
/usr/bin/python

STEP3:编写启动相关服务的 python 脚本
-- 先新建两个文件,一个是python脚本,一个是记录日志
[oracle@REDHAT6 ~]$ touch oracle.py
[oracle@REDHAT6 ~]$ touch oracle.log
[oracle@REDHAT6 ~]$ chmod -R 755 oracle.py

python脚本
import commands;
import sys;
import time;

dtime=time.strftime('%Y-%m-%d %H:%I:%M:%S',time.localtime(time.time()));

file_append=open('/home/oracle/oracle.log','a+')

print>>file_append,dtime,'\n'
print>>file_append,'============START LISTENER================\n'
(status,output)=commands.getstatusoutput("su - oracle -c '/u01/app/oracle/bin/lsnrctl start' ")
print>>file_append,output+'\n'
if(status==0):
	print>>file_append,'============OK: LISTENER START OK=============\n'
else:
	print>>file_append,'============ERROR: LISTENER START ERROR=============\n'

print>>file_append,'============START DATABASE================\n'
(status,output)=commands.getstatusoutput("su - oracle -c '/u01/app/oracle/bin/dbstart' ")
print>>file_append,output,'\n'

if(status==0):
	print>>file_append,'============OK: DATABASE START OK=============\n'
else:
	print>>file_append,'============ERROR: DATABASE START ERROR=======\n'


print>>file_append,'\n','\n'
file_append.close()

脚本先启动lsnrctl, 再启动 dbstart,  在dbstart启动时,会自动启动lsnrctl,由于本人在环境变量中没有配置,所以在启动dbstart时,监听无法启动,所以就在python中先启动了监听


STEP4:将脚本执行命令添加到开机启动中

[oracle@REDHAT6 ~]$ vi /etc/rc.d/rc.local
在该文件中增加一行:su - root -c "python /home/oracle/oracle.py"    有的人说是将 su - root 要改成 oracle用户,这里没有必要改,因为我在python脚本中已经指定了oracle用户

下次启动机器,就会发现监听程序和数据库程序已经启动


最后,我们看看日志文件

[oracle@REDHAT6 ~]$ tail -200 /home/oracle/oracle.log
LINUX下ORACLE自动启动
下面是启动数据库的日志,里面会报监听错误,但是监听我们先已经启动了,所以可以不必理会。也可以通过配置环境变量来启动

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
