oracle--10.2.0.3升级到11.2.0.4

一,环境

  01,待升级的系统  

  升级仅支持10.2.0.2版本之后的系统,如果不是,请把10G升级至高版本!

  本次实验环境10.2.0.3

  

  02,挂载11G系统

  03,升级须知

    1) 做好备份

    

二,DBUA升级

  升级步骤:

  • 在数据库服务器上关闭10.2.0.3数据库监听与数据库
  • 创建oracle 11.2.0.3数据库相关环境变量与目录
  • 在数据库服务器上安装oracle11.2.0.3数据库软件
  • 在orale11.2.0.3环境变量下执行DBUA升级
  • 修改compatible属性

  01,在数据库服务器上关闭10.2.0.3数据库监听与数据库

[oracle@dgwxpdb ~]$ lsnrctl stop
#--SQL>  alter system set compatible='10.2.0.3.0' scope=spfile;
#
#--System altered.
#
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

  02,创建oracle 11.2.0.3数据库相关环境变量与目录

[oracle@dgwxpdb ~]$ vim ~/.bash_profile
[oracle@dgwxpdb ~]$ source ~/.bash_profile
[oracle@dgwxpdb ~]$ cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=ORCL; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
export PATH
[oracle@dgwxpdb ~]$ mkdir $ORACLE_HOME -p
[oracle@dgwxpdb ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/db_1
[oracle@dgwxpdb ~]$

  03,在数据库服务器上安装oracle11.2.0.3数据库软件

  进入到11G安装包上安装

11G的软件就到这里完成了

04,在orale11.2.0.3环境变量下执行DBUA升级

  查看环境是不是正确

执行DBUA

这里是提示看不看升级可行性的报告,如果点NO,会生成上面的html文件,大家第一次升级最好看下,一般警告类的

也可以忽略

备份的话这个怎么说还是做下吧,安全最重要

这里如果大家数据库是归档模式,注意下 Fast Recovery Area Sise的大小,这个2048一定不够。具体多少,我没试过。最好升级前改成非归档模式,反正都停库了,也没事。0.0,

EM根据需要把,我这里不要了

时间好长!!!!!

 

70了

05,修改compatible属性

[oracle@dgwxpdb ~]$ sqlplus / as sysdba
