2.2.5. 備份歸檔日誌並刪除
備份歸檔日誌生成的備份集為/oracle/oradb-20101114-1jlt0ptg_1_1.rman，同時控制檔案和引數檔案也自動備份到/oracle/oradata/autobackup/oradb-cf-c-2485588605-20101114-01.dbf。
注意：這裡自動備份得到的控制檔案是最新的，本環境rman採用的是nocatalog模式，因此該控制檔案備份集中記錄了歸檔日誌檔案的相關資訊，進行資料恢復需要用到。

三、 異機恢復
3.
3.1. 建立組、使用者
3.1.1. groupadd、useradd
在newdbser上建立使用者組、使用者如下：
#groupadd -g 501 oinstall
#groupadd -g 502 dba
#useradd -u 501 -g oinstall -G dba oracle
3.1.2. 編輯使用者配置檔案
export EDITOR=vi
export ORACLE_SID=oradb
export ORACLE_BASE=/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export NLS_LANG="American_america.zhs16gbk"
export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss';
export PATH =$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
3.2. 安裝oracle補丁
因Oracle 10.2.0.1不支援lvm lv裸裝置作為datafile，因此如果直接將備份集恢復到10.2.0.1的話，將出現ORA-27094的錯誤，錯誤日誌如下：

##########以上為10.2.0.1環境下將datafile恢復到裸裝置下的報錯日誌###############
關於ORA-27094，詳見《Linux x86平臺下Oracle 10.2.0.1 ORA-27094》一文。
3.2.1. 停止相關程式
$ emctl stop dbconsole
$ isqlplusctl stop
$ lsnrctl stop
shutdown資料庫例項
如果使用ASM，需要將ASM也shutdown
具體可以檢視補丁包中的patch_note.htm文件。
3.2.2. 備份相關檔案
Oracle recommends that you create a backup of the Oracle Inventory, Oracle 10g home and Oracle 10g Database before you install the patch set.
3.2.3. 設定DISPLAY引數
需要設定DISPLAY才能使用圖形介面方式安裝；若採用靜默安裝，則不需要設定DISPLAY。
3.2.4. 執行runInstaller安裝
% cd patchset_directory/Disk1% ./runInstaller注意：在選擇安裝目錄時，需要指定當初安裝10.2.0.1的目錄即$ORACLE_HOME,否則將安裝失敗。3.3. 建立空例項
對於類Unix平臺，建立oracle空例項實際上就是建立oracle相關的一些目錄。
以oracle使用者執行以下命令建立相關目錄：
$mkdir -p $ORACLE_BASE/oradata/$ORACLE_SID
$mkdir $ORACLE_BASE/admin/$ORACLE_SID
$cd $ORACLE_BASE/admin/$ORACLE_SID
$mkdir pfile bdump udump cdump
3.4. 重建密碼檔案
$orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle
3.5. 設定DBID
