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
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
CORE 11.2.0.4.0 Production
TNS for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production

SQL> set linesize 150;
set pagesize 9999;
col comp_name format a40;
SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;SQL> SQL> SQL>

COMP_NAME VERSION STATUS

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/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
