Redhat 5.4 Orcle RAC 数据库 从10.2.0.1升级到 10.2.0.4
?
?????? 之前安裝的是兩個節點的RAC 平臺。 數據庫版本是10.2.0.1. 這個實驗的目的就是將這個數據庫版本從10.2.0.1 升級到 10.2.0.4. ?升級包可以從Oracle metalink上進行下載，這個下載需要Oracle 付費的帳號。 網絡可能也有資源下載。 10.2.0.4的patch number 是：p6810189。
?
?????? 兩個節點的RAC 安裝，參考Blog：
????????????? Redhat 5.4 + ASM + RAW+ Oracle 10g RAC 安裝文檔
????????????? http://blog.csdn.net/tianlesoftware/archive/2010/09/09/5872593.aspx
?
升級過程和單節點的升級差不多。 10g 單節點的升級參考Blog：
?????? Oracle 10g upgrade from 10.2.0.1 to 10.2.0.4
?????? http://blog.csdn.net/tianlesoftware/archive/2010/04/21/5507762.aspx
?
?
RAC 環境下的升級分三步。 這個在patch 包里的readme 文檔里有詳細的說明。
?????? 1. 升級clusterware? -- > 升級包中安裝程序里選擇CRS_HOME后安裝
?????? 2. 升級數據庫軟件? -- >升級包中安裝程序里選擇ORACLE_HOME后安裝
?????? 3. 升級實例??? -- > 可以使用腳本 或者直接運行DBUA 實現, 如果用腳本,參考單節點的升級
?
?
RAC 的升級分滾動升級升級和非滾動升級。
?????? 滾動升級就是每次升級一個節點。
?????? 非滾動就是一次升級所有節點。
?
?這個patch包的readme文檔也有說明。這次升級用的是非滾動升級。 即一次性搞定所有節點。
?
注意：
?????? 如果是生產庫，在升級之前做好備份。 備份數據庫（如：RMAN），備份ORA_CRS_HOME 目錄，備份ORACLE_HOME目錄。 雖然很少會出現問題，但是如果出現問題，誰來為我們的錯誤買單，所以作為一個DBA 要銘記于心的就是備份。
?
一.? 從客戶端查看現在的版本
?
1.1 修改tnsnames.Ora 文件，增加一下內容：
RAC =
? (DESCRIPTION =
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 110.853.10.1)(PORT = 1521))
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 10.85.10.2)(PORT = 1521))
????? (LOAD_BALANCE=YES)
????? (
CONNECT_DATA=
?(SERVER=DEDICATED)
?(SERVICE_NAME=ORCL)
?(
?? FAILOVER_MODE=
? (TYPE=session)
? (METHOD=basic)
? (RETRIES=180)
? (DELAY=5)
?)
?
)
)
?
1.2 ?客戶端用sqlplus 連接數據庫, 查看數據庫版本信息
?
C:/Users/Administrator.DavidDai>sqlplus /nolog

?
查看版本其實沒必要這么復雜，這里是額外的演示一下客戶端如何連接RAC.
?
?
二. 升級Clusterware 軟件
?
2.1 將升級包mout到linux系統
??? 用root用戶登陸系統，執行如下命令：
??? mount -o username=administrator,password=12345678 //10.85.10.80/Software /mnt
?
2.2 停止相關的進程
?
??? 2.2.1每個節點分別停止?EM和?isqlplus
?????? [oracle@rac1 bin]$ emctl stop dbconsole
?????? [oracle@rac1 bin]$ isqlplusctl stop
?
??? 2.2.2 ?停止相關進程
?????? 這個可以用srvctl 命令來一個一個進行，也可以用crs_stop -all 進行。
????
??? 這部分內容參考Blog：
?????? Oracle RAC 啟動與關閉
?? http://blog.csdn.net/tianlesoftware/archive/2010/03/05/5349003.aspx
?
[oracle@rac1 bin]$ crs_stat -t

?
?
2.2.3 停止每個節點上的CRS
[root@rac1 ~]# /u01/app/oracle/product/crs/bin/crsctl stop crs
?
?
2.3 用Xmanger 工具運行runInstaller
?
2.3.1 先在Xmanager 工具里面指定DISPLAY 變量
??? [oracle@rac1 ~]$ export DISPLAY=10.85.10.80:0.0
?
2.3.2 進行升級包的目錄，運行runInstaller
?
??? [oracle@rac1 p6810189_10204_Linux-x86]$ pwd
?????? /mnt/OracleSoftware/p6810189_10204_Linux-x86
??? [oracle@rac1 p6810189_10204_Linux-x86]$ cd Disk1/
??? [oracle@rac1 Disk1]$ ls
??? 10204_buglist.htm? install? patch_note.htm? response? runInstaller? stage
??? [oracle@rac1 Disk1]$ ./runInstaller -ignoreSysPreReqs
?????? -- 因為我用的是redhat 5，所以忽略了版本檢查
?
2.3.3 在可視化的安裝窗口選擇CRS_HOME。看清楚，不要選錯了。然后一下步進行安裝。
?
?
2.3.4 安裝結束會提示運行2個腳本
?
???
??? The installer has detected that your Cluster Ready Services (CRS) installation is shared amongst the following nodes:
?
??? rac1
??? rac2
?
Because of the shared nature of this installation, you cannot perform a rolling upgrade of your CRS software.
?
To complete the installation of this patchset, you must perform the following tasks:
?
??? 1.? On each node, do the following:
?????? a.? Log in as the root user.
?????? b.? As root, shutdown the CRS daemons on the node
?????????? using the following command:
????????????? /u01/app/oracle/product/crs/bin/crsctl stop crs
?????? Repeat this step until the CRS daemons on all the nodes are shutdown.
?
??? 2.? After all the CRS daemons on all the nodes are shutdown,
?????? run the shell script located at:
?????????? /u01/app/oracle/product/crs/install/root102.sh
?????? This script will automatically start the CRS daemons on the
?????? patched node upon completion.
?
??? 3.? Wait until the script finishes and then proceed to the
?????? ?next node and repeat step 2.
?

?
?
三. 升級數據庫軟件
??? 上升級clusterware的時候，升級結束的時候會啟動CRS服務。 我們在升級數據庫的時候需要關閉這些服務。
?
3.1 停止相關進程
??? [oracle@rac1 bin]$ crs_stop -all
??? [oracle@rac1 bin]$ crs_stat -t

?
3.2 用Xmanger 工具運行runInstaller
?
3.2.1 先在Xmanager 工具里面指定DISPLAY 變量
??? [oracle@rac1 ~]$ export DISPLAY=10.85.10.80:0.0
?
3.2.2 進行升級包的目錄，運行runInstaller
???
??? 在可視化的安裝窗口選擇ORACLE_HOME。看清楚，不要選錯了。然后一下步進行安裝。
?
?
3.2.3? 安裝結束會提示用root用戶在所有節點上運行一個腳本
??? /u01/app/oracle/product/10.2.0/db_1/root.sh
?
[root@rac1 ~]# /u01/app/oracle/product/10.2.0/db_1/root.sh
Running Oracle10 root.sh script...
?
The following environment variables are set as:
??? ORACLE_OWNER= oracle
??? ORACLE_HOME=? /u01/app/oracle/product/10.2.0/db_1
?
Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin.? Overwrite it? (y/n)
[n]: y
?? Copying dbhome to /usr/local/bin ...
The file "oraenv" already exists in /usr/local/bin.? Overwrite it? (y/n)
[n]: y
?? Copying oraenv to /usr/local/bin ...
The file "coraenv" already exists in /usr/local/bin.? Overwrite it? (y/n)
[n]: y
?? Copying coraenv to /usr/local/bin ...
?
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
?
?
四. 升級實例
?
升級實例有兩種方法：
??? 1. DBUA
??? 2. 手動執行腳本
?
4.1 用腳本升級
?
After you install the patch set, you must perform the following steps on every database associated with the upgraded Oracle home:
?
| Note: If you do not run the catupgrd.sql script as described in this section and you start up a database for normal operation, then ORA-01092: ORACLE instance terminated. Disconnection forced errors will occur and the error ORA-39700: database must be opened with UPGRADE option will be in the alert log. |
?
$ srvctl start listener -n node
?? $ sqlplus /nolog
?? SQL> CONNECT SYS AS SYSDBA
?? Enter password: SYS_password
?? SQL> STARTUP NOMOUNT
?? SQL> ALTER SYSTEM SET CLUSTER_DATABASE=FALSE SCOPE=spfile;
?? SQL> SHUTDOWN
SQL> STARTUP UPGRADE
SQL> SPOOL patch.log
SQL> @?/rdbms/admin/catupgrd.sql
SQL> SPOOL OFF
This list provides the version and status of each SERVER component in the database.
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP
SQL> @?/rdbms/admin/utlrp.sql
?
?
| Note: When the 10.2.0.4 patch set is applied to an Oracle Database 10g Standard Edition database, there may be 54 invalid objects after the utlrp.sql script runs. These objects belong to the unsupported components and do not affect the database operation. Ignore any messages indicating that the database contains invalid recycle bin objects similar to the following: BIN$4lzljWIt9gfgMFeM2hVSoA==$0 |
?
SQL> select comp_name, version, status from sys.dba_registry;
In the output of the preceding command, the status of all the components should be VALID for a successful upgrade.
$ rman catalog username/password@alias
?SQL> ALTER SYSTEM SET CLUSTER_DATABASE=TRUE SCOPE=spfile;
SQL> SHUTDOWN
SQL> STARTUP
$ srvctl start service -d db_name -s service_name
Ensure the database and Listener are operational.
- In the case of a single instance, execute
emca -upgrade db
- In the case of Oracle Real Application Clusters (RAC), execute
emca -upgrade db -cluster
?
4.2 用DBUA升級
??? 使用DBUA工具的話，會把升級的一些代碼封裝起來，我們只需要在界面上點點就可以了。所以比較方便。在一個節點運行DBUA即可。 會同時升級2個節點的實例。
?
4.2.1 啟動相關的進程
??? [oracle@rac1 bin]$ crs_start -all
?
?
4.2.2 運行dbua?
?
[oracle@rac1 ~]$ export DISPLAY=192.168.1.111:0.0
[oracle@rac1 ~]$ dbua
?
說明：
?????? （1）啟動dbua工具后，會提示選擇升級ASM還是數據庫，這里是從10.2.0.1的基礎上升級，不需要升級ASM，直接跳過,如低于此版本而是必須先升級ASM。
??? （2）運行過程中有選項是否編譯無效的對象。默認勾上。在升級之后會自己編譯無效對象。
??? （3）運行需要一個小時左右。
???
?安裝結束后會提示安裝日志存放目錄：
??? /u01/app/oracle/product/10.2.0/db_1/cfgtoollogs/dbua/orcl/upgrade/
?
?
?
五. 驗證
??? 我們還是從客戶端來驗證，監聽之前已經配好了。

?
已選擇18行。
?
?
順便驗證一下RAC的性能，我們看到現在連的是oracl2. 我們上服務器，把這個實例停掉。在查看連哪個實例。
?
[oracle@rac1 upgrade]$ export ORACLE_SID=orcl2
[oracle@rac1 upgrade]$ sqlplus /nolog

?
SQL> conn / as sysdba;

SQL>
?
我們在客戶端在查詢一下看看：
SQL> select instance_name from V$instance;
?
INSTANCE_NAME
--------------------------------
orcl1
?
注意：這里自動切換到了orcl1 實例。 這個就體現RAC的價值，當一個實例宕掉后，不會影響系統的運行。
?
至此，RAC的升級結束。
