1、准備安裝
查看當前oracle版本，確定是比較舊的11.2.0.1

2、開始升級
C:\pic\oracle\100.png，填寫郵箱地址（也可以忽略不填寫），然後下一步
選擇忽略軟件升級，下一步嗎，如101.png
然後選擇升級，如下102.png
然後繼續進行，有個INS-35373錯誤，選擇Yes，如下
然後選擇好語言種類，簡體中文、繁體中文、英語、美式英語等，如104.png所示：
繼續下一步，選擇企業版，如
接下來，開始選擇oracle目錄了，是選擇新建的目錄呢還是選擇原來的老版本11.2.0.1的目錄呢？這裡最好選擇一個新的目錄，因為萬一升級失敗了，老的oracle版本軟件目錄沒有被覆蓋掉，還可以繼續使用的，否則升級失敗，就基本只有徹底暴力清除所有文件以及注冊信息，之後重新安裝oracle了。
我這裡就選擇一個新的目錄11.2.0.4的目錄，如106.png、107.png所示
接下來，繼續，選擇新的的Inventory Directory目錄，默認的會報錯，如108.png所示
接下來選擇用戶組和操作組，如109.png所示：
接下來，會有checking各種lib包，一些比較偏的，缺少了也沒事，直接Ignore忽略掉就ok，如110.png所示：
下一步看安裝的目錄以及基本信息，如111.png所示：
然後點擊“”Install“”按鈕，開始安裝，如圖112.png
中級需要執行配置腳本，如圖112_1.png
重新打開xshell，ssh連接到數據庫，在命令行去執行命令：
[root@hch_test_121_90 oracle]# bash -x/oracle/app/oraInventory11.2.0.4/orainstRoot.sh [root@hch_test_121_90 oracle]# bash -x/oracle/app/oracle/product/11.2.0.4/dbhome_1/root.sh
執行過程如下：
[root@hch_test_121_90 oracle]# bash -x /oracle/app/oraInventory11.2.0.4/orainstRoot.sh
+ AWK=/bin/awk
+ CHMOD=/bin/chmod
+ CHGRP=/bin/chgrp

+ '[' -d /etc ']'
+ /bin/chmod 755 /etc
+ '[' -f /oracle/app/oraInventory11.2.0.4/oraInst.loc ']'
+ /bin/cp /oracle/app/oraInventory11.2.0.4/oraInst.loc /etc/oraInst.loc

+ /bin/echo 'The execution of the script is complete.'
The execution of the script is complete.
[root@hch_test_121_90 oracle]#
[root@hch_test_121_90 oracle]#
[root@hch_test_121_90 ~]# sh /oracle/app/oracle/product/11.2.0.4/dbhome_1/root.sh
Performing root user operation for Oracle 11g

Database Configuration Assistant when a database is created

Now product-specific root actions will be performed.
Finished product-specific root actions.
[root@hch_test_121_90 ~]#
之後回到vnc遠程的窗口，點擊界面的OK，會提示安裝Oracle Net Configuration Assistant: Welcome操作：
接下來會配置網絡，如下113.png、114.png
設置sys密碼，如115.png所示
看到這裡，問題來了，中間沒有數據庫讓你選擇去升級，問題在哪裡呢，在/etc/oratab沒有配置，所以趕緊去配置：
[root@hch_test_121_90 ~]# more /etc/oratab # # This file is used by ORACLE utilities. It is created by root.sh # and updated by either Database Configuration Assistant while creating # a database or ASM Configuration Assistant while creating ASM instance. # A colon, ':', is used as the field terminator. A new line terminates # the entry. Lines beginning with a pound sign, '#', are comments. # # Entries are of the form: # $ORACLE_SID:$ORACLE_HOME:<N|Y>: # # The first and second fields are the system identifier and home # directory of the database respectively. The third filed indicates # to the dbstart utility that the database should , "Y", or should not, # "N", be brought up at system boot time. # # Multiple entries with the same $ORACLE_SID are not allowed. # powerdes:/hom/oracle/app/oracle/product/11.2.0/dbhome_1:Y [root@hch_test_121_90 ~]#
配置完後，前面的步驟重新來一遍，到此就會有下面的出現的database選擇項讓我們選擇，如116.png、117.png、118.png所示：
接下來，選擇升級時區以及備份數據庫，如119.png所示：
選擇升級過程中不移動數據文件，如圖120.png
選擇默認的閃回恢復區以及恢復區大小，也可以自己手動調整，如121.png
接下來默認下一步，准備企業管理器，當然也可以選擇不需要的，直接忽略掉，如下圖122.png
接下來，點擊“Finish”按鈕（這個時間會比較長，至少1個小時吧，我這裡用了1.5個小時，可能在ssd上時間比較短），如圖123.png、124.png、125.png所示
OK，等待進度條變成100%，然後基本的升級就好了，就完成了，後續記得修改.bash_profile裡面的ORACLE_HOME目錄為新的11.2.0.4目錄即可。
