Redhat 5.4 Orcle RAC 数据库 从10.2.0.1升级到 10.2.0.4

 之前安装的是两个节点的RAC 平台。 数据库版本是10.2.0.1. 这个实验的目的就是将这个数据库版本从10.2.0.1 升级到 10.2.0.4.  升级包可以从Oracle metalink上进行下载，这个下载需要Oracle 付费的帐号。 网络可能也有资源下载。 10.2.0.4的patch number 是：p6810189。

 

       两个节点的RAC 安装，参考Blog：

              Redhat 5.4 + ASM + RAW+ Oracle 10g RAC 安装文档

              http://blog.csdn.net/xujinyang/article/details/6837265

 

升级过程和单节点的升级差不多。 10g 单节点的升级参考Blog：

       Oracle 10g upgrade from 10.2.0.1 to 10.2.0.4

       http://blog.csdn.net/xujinyang/article/details/6829567

 

 

RAC 环境下的升级分三步。 这个在patch 包里的readme 文档里有详细的说明。

       1. 升级clusterware  -- > 升级包中安装程序里选择CRS_HOME后安装

       2. 升级数据库软件  -- >升级包中安装程序里选择ORACLE_HOME后安装

       3. 升级实例    -- > 可以使用脚本 或者直接运行DBUA 实现, 如果用脚本,参考单节点的升级

 

 

RAC 的升级分滚动升级升级和非滚动升级。

       滚动升级就是每次升级一个节点。

       非滚动就是一次升级所有节点。

 

 这个patch包的readme文档也有说明。这次升级用的是非滚动升级。 即一次性搞定所有节点。

 

注意：

       如果是生产库，在升级之前做好备份。 备份数据库（如：RMAN），备份ORA_CRS_HOME 目录，备份ORACLE_HOME目录。 虽然很少会出现问题，但是如果出现问题，谁来为我们的错误买单，所以作为一个DBA 要铭记于心的就是备份。

 

一.  从客户端查看现在的版本

 

1.1 修改tnsnames.Ora 文件，增加一下内容：

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  客户端用sqlplus 连接数据库, 查看数据库版本信息

 

C:/Users/Administrator.DavidDai>sqlplus /nolog

查看版本其实没必要这么复杂，这里是额外的演示一下客户端如何连接RAC.

 

 

二. 升级Clusterware 软件

 

2.1 将升级包mout到linux系统

    用root用户登陆系统，执行如下命令：

    mount -o username=administrator,password=12345678 //10.85.10.80/Software /mnt

 

2.2 停止相关的进程

 

    2.2.1每个节点分别停止 EM和 isqlplus

       [oracle@rac1 bin]$ emctl stop dbconsole

       [oracle@rac1 bin]$ isqlplusctl stop

 

    2.2.2  停止相关进程

       这个可以用srvctl 命令来一个一个进行，也可以用crs_stop -all 进行。

    

    这部分内容参考Blog：

2.2.3 停止每个节点上的CRS

[root@rac1 ~]# /u01/app/oracle/product/crs/bin/crsctl stop crs

 

 

2.3 用Xmanger 工具运行runInstaller

 

2.3.1 先在Xmanager 工具里面指定DISPLAY 变量

    [oracle@rac1 ~]$ export DISPLAY=10.85.10.80:0.0

 

2.3.2 进行升级包的目录，运行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

       -- 因为我用的是redhat 5，所以忽略了版本检查

 

2.3.3 在可视化的安装窗口选择CRS_HOME。看清楚，不要选错了。然后一下步进行安装。

 

 

2.3.4 安装结束会提示运行2个脚本

 

   

    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. 升级数据库软件

    上升级clusterware的时候，升级结束的时候会启动CRS服务。 我们在升级数据库的时候需要关闭这些服务。

 

3.1 停止相关进程

    [oracle@rac1 bin]$ crs_stop -all

    [oracle@rac1 bin]$ crs_stat -t

Name           Type           Target    State     Host

3.2 用Xmanger 工具运行runInstaller

 

3.2.1 先在Xmanager 工具里面指定DISPLAY 变量

    [oracle@rac1 ~]$ export DISPLAY=10.85.10.80:0.0

 

3.2.2 进行升级包的目录，运行runInstaller

   

    在可视化的安装窗口选择ORACLE_HOME。看清楚，不要选错了。然后一下步进行安装。

 

 

3.2.3  安装结束会提示用root用户在所有节点上运行一个脚本

    /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)

   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. 升级实例

 

升级实例有两种方法：

    1. DBUA

    2. 手动执行脚本

 

4.1 用脚本升级

 

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.

 

1. Log in as the Oracle software owner user.
2. For Oracle RAC installations, start listener on each node of the cluster as follows:

$ srvctl start listener -n node

1. If you are using Automatic Storage Management, start the Automatic Storage Management instance.
2. For Oracle RAC installations:
   1. Use SQL*Plus to log in to the database as the SYS user with SYSDBA privileges:

   $ sqlplus /nolog

   SQL> CONNECT SYS AS SYSDBA

   Enter password: SYS_password

   SQL> STARTUP NOMOUNT

1.  
   1. Set the CLUSTER_DATABASE initialization parameter to FALSE:

   SQL> ALTER SYSTEM SET CLUSTER_DATABASE=FALSE SCOPE=spfile;

1.  
   1. Shut down the database:

   SQL> SHUTDOWN

1. Enter the following SQL*Plus commands:

SQL> STARTUP UPGRADE

SQL> SPOOL patch.log

SQL> @?/rdbms/admin/catupgrd.sql

SQL> SPOOL OFF

1. Review the patch.log file for errors and inspect the list of components that is displayed at the end of catupgrd.sql script.

This list provides the version and status of each SERVER component in the database.

1. If necessary, rerun the catupgrd.sql script after correcting any problems.
2. Restart the database:

SQL> SHUTDOWN IMMEDIATE

SQL> STARTUP

1. Run the utlrp.sql script to recompile all invalid PL/SQL packages now instead of when the packages are accessed for the first time. This step is optional but recommended.

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.sqlscript 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

 

1. Run the following command to check the status of all the components after the upgrade:

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.

1. If you are using the Oracle Recovery Manager catalog, enter the following command:

$ rman catalog username/password@alias

1. For Oracle RAC installations:
   1. Set the CLUSTER_DATABASE initialization parameter to TRUE:

 SQL> ALTER SYSTEM SET CLUSTER_DATABASE=TRUE SCOPE=spfile;

1.  
   1. Restart the database:

SQL> SHUTDOWN

SQL> STARTUP

1.  
   1. Start any database services that you want to use:

$ srvctl start service -d db_name -s service_name

1. To configure and secure Enterprise Manager follow these steps:

Ensure the database and Listener are operational.

1.  
   • In the case of a single instance, execute

emca -upgrade db

1.  
   • In the case of Oracle Real Application Clusters (RAC), execute

emca -upgrade db -cluster

 

4.2 用DBUA升级

    使用DBUA工具的话，会把升级的一些代码封装起来，我们只需要在界面上点点就可以了。所以比较方便。在一个节点运行DBUA即可。 会同时升级2个节点的实例。

 

4.2.1 启动相关的进程

    [oracle@rac1 bin]$ crs_start -all

 

 

4.2.2 运行dbua 

 

[oracle@rac1 ~]$ export DISPLAY=192.168.1.111:0.0

[oracle@rac1 ~]$ dbua

 

说明：

       （1）启动dbua工具后，会提示选择升级ASM还是数据库，这里是从10.2.0.1的基础上升级，不需要升级ASM，直接跳过,如低于此版本而是必须先升级ASM。

    （2）运行过程中有选项是否编译无效的对象。默认勾上。在升级之后会自己编译无效对象。

    （3）运行需要一个小时左右。

   

 安装结束后会提示安装日志存放目录：

    /u01/app/oracle/product/10.2.0/db_1/cfgtoollogs/dbua/orcl/upgrade/

 

 

 

五. 验证

    我们还是从客户端来验证，监听之前已经配好了。
