1、準備安裝
查看當前oracle版本，確定是比較舊的11.2.0.1
[oracle@hch_test_121_90 ~]$ rlwrap sqlplus / as sysdba

2、開始升級
C:\pic\oracle\100.png，填寫郵箱地址（也可以忽略不填寫），然后下一步
選擇忽略軟件升級，下一步嗎，如101.png
然后選擇升級，如下102.png
然后繼續(xù)進行，有個INS-35373錯誤，選擇Yes，如下
然后選擇好語言種類，簡體中文、繁體中文、英語、美式英語等，如104.png所示：
繼續(xù)下一步，選擇企業(yè)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？這里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(xù)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，之后重新安裝oracle了。
我這里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(xù)，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：
然后點擊“”Install“”按鈕，開始安裝，如圖112.png
中級需要執(zhí)行配置腳本，如圖112_1.png
重新打開xshell，ssh連接到數(shù)據(jù)庫，在命令行去執(zhí)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(zhí)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

+ /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
The following environment variables are set as:

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 ~]#
之后回到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(wǎng)絡(luò)，如下113.png、114.png
設(shè)置sys密碼，如115.png所示
看到這里，問題來了，中間沒有數(shù)據(jù)庫讓你選擇去升級，問題在哪里呢，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 ~]#
配置完后，前面的步驟重新來一遍，到此就會有下面的出現(xiàn)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(qū)以及備份數(shù)據(jù)庫，如119.png所示：
選擇升級過程中不移動數(shù)據(jù)文件，如圖120.png
選擇默認的閃回恢復區(qū)以及恢復區(qū)大小，也可以自己手動調(diào)整，如121.png
接下來默認下一步，準備企業(yè)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，我這里用了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%，然后基本的升級就好了，就完成了，后續(xù)記得修改.bash_profile里面的ORACLE_HOME目錄為新的11.2.0.4目錄即可。
