图形化升级单机oracle 11.2.0.4 到 12.2.0.1
1. 讲补丁包上传到 Oracle server ，解压、安装
[oracle@11g tmp]$ unzip linuxx64_12201_database.zip
2. 检查当前版本
SQL> select * from v$version;
BANNER

3. 检查磁盘空间
select a.tablespace_name, round(a.total_size) "total_size(mb)",
round(a.total_size) - round(b.free_size,3) "unsed_size(mb)",
round(b.free_size,3) "free_size(mb)",
round(b.free_size/total_size *100,2) ||'%' free_rate
from
(select tablespace_name,sum(bytes) /1024/1024 total_size
from dba_data_files
group by tablespace_name) a,
(select tablespace_name,sum(bytes)/1024/1024 free_size
from dba_free_space
group by tablespace_name) b
where a.tablespace_name=b.tablespace_name(+);
4.为数据库做冷备份
RMAN>run {
shutdown immediate;
startup mount;
allocate channel c1 type disk;
allocate channel c2 type disk;
backup full tag='db_full_bak' database format '/home/oracle/rmanbak/full_cold_%d_%s.bak';
alter database open;
}
RMAN> list backup;
数据库正常关闭后，还需要备份Oracle主目录，目的还是为了升级失败时，能够还原出数据库软件到升级前的版本。
重点是如下目录：
ORACLE_HOME/dbs
ORACLE_HOME/network/admin
ORACLE_HOME/hostname_dbname
ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_hostname_dbname
[oracle@11g ~]$ env|grep ORA
ORACLE_SID=orcl
ORACLE_BASE=/home/oracle/app
ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0.4/dbhome_1
[oracle@11g ~]$ tar cvf oracle.ora /home/oracle
5. 关闭数据库实例及相关进程 (静态监听、动态监听、EOM、相关服务)
--停止数据库外部进程
[root@11g ~]#ps -ef|grep -v grep |grep LOCAL=NO|awk '{print $2}'|xargs kill -9
SQL> shutdown immediate;
[oracle@11g rmanbak]$ cat /home/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
[oracle@11g rmanbak]$ lsnrctl stop
[oracle@11g rmanbak]$ lsnrctl status
[oracle@11g rmanbak]$ ps -ef |grep ora_|grep -v grep
[oracle@11g rmanbak]$ netstat -an |grep 1521
[oracle@11g rmanbak]$ netstat -an |grep 1158
6. 开始升级操作
[oracle@11g ~]$ cd /tmp/database
[oracle@11g database]$ ./runInstaller
6.1 不勾选 
， 点击 next
注意这里的安装位置，我之前的安装目录是11.2.0.4，我新目录是12.2.0.1.0 即将oracle 安装到其他位置，这样可以减少宕机时间，也是oracle 推荐的方法。
有pdksh或者ksh其中一个就行
[root@11g ~]# rpm -qa|grep ksh
pdksh-5.2.14-1.i386
执行到78%的时候弹出如下窗口： 用 root 用户跑这个脚本
进度到了83%的时候，自动弹出dbua窗口
停在37%执行了很久，耐心等待
选abort强制，进行如下操作
选yes
最后点击close。
7. 修改环境变量
然后，再修改oracle用户的.bash_profile
ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1.0/db_1
然后source ~/.bash_profile
查看 cat /etc/oratab 【内容应该是新目录】
8. 登录查看，升级后版本
[oracle@11g ~]$ sqlplus / as sysdba

至此失效对象无法valid，推测是版本升级废弃对象，这里先不讨论。
9. 修改compatible参数，若修改完成，此次升级操作就无法回退，一定要在应用经过测试之后修改。

升级过程有忽略，abort,很简单粗暴，只用来初次尝试，用来学习与参考，失效对象还要进一步确认，升级过程中有不合理之处请指正，转载请标明出处
