系统环境：
Linux standby 2.6.32-573.el6.x86_64 #1 SMP Wed Jul 1 18:23:37 EDT 2015 x86_64 x86_64x86_64 GNU/Linux
1. 讲补丁包上传到 oracle server ，解压、安装
[root@standby database]#unzip p13390677_112040_Linux-x86-64_1of7.zip -d /tmp&& unzip p13390677_112040_Linux-x86-64_2of7.zip -d /tmp
2. 检查当前版本
SQL> select * from v$version;
BANNER

3. 检查磁盘空间（system 必须要最少 10m）(新home最少4.7GB)
SQL> select a.tablespace_name, round(a.total_size) \round(a.total_size) - round(b.free_size,3) \round(b.free_size,3) \
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=’full_bak' database format '/home/oracle/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 bk.tar $ORACLE_HOME
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 |grepora_|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
6.2 选择 skip software updates
6.3 选择 upgrade an existing database
可能报错数据库实例未检测
6.4 选择语言
