1. 講補丁包上傳到 server ，解壓、安裝

[oracle@11g tmp]$ unzip linuxx64_12201_database.zip

2. 檢查當前版本

SQL> select * from v$version;

3. 檢查磁碟空間

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/11.2.0.4/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

注意這裡的安裝位置，我之前的安裝目錄是11.2.0.4，我新目錄是12.2.0.1.0 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。

有pdksh或者ksh其中一個就行

[root@11g ~]# rpm -qa|grep ksh
pdksh-5.2.14-1.i386

執行到78%的時候彈出如下視窗：用 root 使用者跑這個指令碼

進度到了83%的時候，自動彈出dbua視窗

停在37%執行了很久，耐心等待

選abort強制，進行如下操作

選yes

最後點選close。

7. 修改環境變數

然後，再修改oracle使用者的.bash_profile

ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1.0/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

手動單個單個編譯失效物件，結果每個報 Warning: Procedure altered with compilation errors.

至此失效物件無法valid，推測是版本升級廢棄物件，這裡先不討論。

9. 修改compatible引數，若修改完成，此次升級操作就無法回退，一定要在應用經過之後修改。

升級過程有忽略，abort,很簡單粗暴，只用來初次嘗試，用來學習與參考，失效物件還要進一步確認，升級過程中有不合理之處請指正，轉載請標明出處

圖形化升級單機oracle 11.2.0.4 到 12.2.0.1
