圖形化升級單機oracle 11.2.0.1 到 11.2.0.4

1. 講補丁包上傳到 oracle server ，解壓、安裝

[root@11g ~]#unzip p13390677_112040_Linux-x86-64_1of7.zip -d /tmp && unzip p13390677_112040_Linux-x86-64_2of7.zip -d /tmp

2. 檢查當前版本
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
Spatial 11.2.0.1.0 VALID
Oracle Multimedia 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 Workspace Manager 11.2.0.1.0 VALID
Oracle Database Catalog Views 11.2.0.1.0 VALID
Oracle Database Packages and Types 11.2.0.1.0 VALID
JServer JAVA Virtual Machine 11.2.0.1.0 VALID
Oracle XDK 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. 檢查磁碟空間（system 必須要最少 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.為資料庫做冷備份

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;

資料庫正常關閉後，還需要備份Oracle主目錄，目的還是為了升級失敗時，能夠還原出資料庫軟體到升級前的版本。
重點是如下目錄：

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. 關閉資料庫例項及相關程式 (靜態監聽、動態監聽、EOM、相關服務)

--停止資料庫外部程式
[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. 開始升級操作
[oracle@11g ~]$ cd /tmp/database
[oracle@11g database]$ ./runInstaller

6.1 不勾選   ， 點選 next

6.2 選擇  skip software updates

6.3 選擇 upgrade an existing database

6.4 選擇語言

 6.5 選擇 enterprise edition

6.6  注意這裡的安裝位置，我之前的安裝目錄是11.2.0，我新目錄是11.2.0.4 即將oracle 安裝到其他位置，這樣可以減少當機時間，也是oracle 推薦的方法。

6.7 執行到76%的時候彈出如下視窗： 用 root 使用者跑這個指令碼

下面就是一個配置監聽的過程

隨後就是 會自動呼叫DBUA 來升級我們的例項(1---7步)

 7. 修改環境變數

然後，再修改oracle使用者的.bash_profile

ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1

然後source ~/.bash_profile

檢視 cat /etc/oratab   【內容應該是新目錄】

8. 登入檢視，升級後版本

[oracle@11g ~]$ sqlplus / as sysdba

-- 最後修改 compatible 引數 ，切記這個引數已修改，此次升級操作就無法回退，一定要在應用經過測試之後修改。
