图形化升级单机oracle 11.2.0.1 到 11.2.0.4

2022-01-22 13:07:42

1. 讲补丁包上传到 oracle server ，解压、安装

[root@11g ~]#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
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

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

COMP_NAME VERSION STATUS
---------------------------------------- ------------------------------ --------
OWB 11.2.0.1.0 VALID
Oracle Application Express 3.2.1.00.10 VALID
Oracle Enterprise Manager 11.2.0.1.0 VALID
OLAP Catalog 11.2.0.1.0 VALID

Oracle XML Database 11.2.0.1.0 VALID
Oracle Text 11.2.0.1.0 VALID
Oracle Expression Filter 11.2.0.1.0 VALID
Oracle Rules Manager 11.2.0.1.0 VALID

Oracle Database Java Packages 11.2.0.1.0 VALID
OLAP Analytic Workspace 11.2.0.1.0 VALID
Oracle OLAP API 11.2.0.1.0 VALID

18 rows selected.

3. 检查磁盘空间（system 必须要最少 10m）

SQL> 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

6.1 不勾选，点击 next

6.2 选择 skip software updates

6.3 选择 upgrade an existing database

6.4 选择语言

6.5 选择 enterprise edition

6.6 注意这里的安装位置，我之前的安装目录是11.2.0，我新目录是11.2.0.4 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。

6.7 执行到76%的时候弹出如下窗口：用 root 用户跑这个脚本

下面就是一个配置监听的过程

随后就是会自动调用DBUA 来升级我们的实例(1---7步)

7. 修改环境变量

然后，再修改oracle用户的.bash_profile

ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/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

-- 最后修改 compatible 参数，切记这个参数已修改，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。
