10g RAC下安裝10.2.0.4補丁

1.檢查目前補丁的狀態：

SQL> select version from v$timezone_file;

VERSION
----------
2
2.檢查oracle_home和oracle_sid的環境變數：

rac1-> more .bash_profile
export PATH
unset USERNAME

export PS1="`/bin/hostname -s`-> "
export EDITOR=vi
export ORACLE_SID=orcl1
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:$PATH
umask 022

已經設定，可以考慮不必設定。

3.停止所有的服務

$ emctl stop dbconsole
$ isqlplusctl stop
$ lsnrctl stop

1.首先升級CRS

1.每節點都需要在root使用者下執行：

#u01/oracle/product/10.2.0/crs_1/bin/crsctl stop crs

Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.

備註：如果上面步驟沒做，執行下面命令會出現如下報錯

[root@rac2 oracle]# /u01/oracle/product/10.2.0/crs_1/install/root102.sh
Please shut down the following processes before running this script.
20629 ?        00:00:59 ocssd.bin
14155 ?        00:01:18 crsd.bin
20426 ?        00:00:23 evmd.bin

查詢每個節點狀態：

rac1-> crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.

rac2-> CRS-0184: Cannot communicate with the CRS daemon.
bash: CRS-0184:: command not found

2.每個節點都需要在root使用者下執行：

[root@rac1 oracle]# /u01/oracle/product/10.2.0/crs_1/install/root102.sh

備註：安裝文件的說明，在一個節點執行完畢之後，才能執行另外一個節點。

然後開始升級DB 。升級DB前要使用“/u01/oracle/product/10.2.0/crs_1/bin/crsctl stop crs”關閉CRS程式，否則升級DB出錯。

注意對兩個節點分別都需要執行./runinstaller,升級ＣＲＳ．

最後要在每個節點執行root.sh指令碼。

[root@rac1 ~]# /u01/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/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.

[root@rac2 ~]# /u01/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/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.

最後一步：升級監聽程式：

使用dbua對監聽升級後，升級完畢。

rac1-> sqlplus /nolog

討論：如果針對在ＡＩＸ環境下的ＲＡＣ，是否是把ＨＡＣＭＰ停掉打補丁會更安全？
