oracle10g数据库复制,oracle -10g 中Duplicate 复制数据库
oracle --10g 中Duplicate 復制數據庫
本次實驗通過duplicate命令，在本機環境中創建一個復制數據庫。目標數據庫為hongye、復制數據庫為catdb。
環境別名設置：
alias sql='rlwrap sqlplus /nolog'
alias rman='rlwrap rman'
alias dbs='cd $ORACLE_HOME/dbs'
alias rdb='cd $ORACLE_HOME/rdbms/admin'
alias udu='cd $ORACLE_BASE/admin/$ORACLE_SID/udump'
alias bdu='cd $ORACLE_BASE/admin/$ORACLE_SID/bdump'
alias rmalert='rm -f $ORACLE_BASE/admin/$ORACLE_SID/bdump/*;rm -f $ORACLE_BASE/admin/$ORACLE_SID/udump/*'
詳細步驟如下：
1、構建catdb的初始化參數文件，本次實驗使用的參數文件是從hongye數據庫中創建出來的，并做了一些修改。
注意參數db_file_name_convert和log_file_name_convert參數，這兩個參數控制了數據文件和日志文件的重命名，關于數據文件的重命名也可以使用set newname命令，日志文件的重命名可以在duplicate命令的子句中指定，但均沒有init參數中的轉換方便。
db_file_name_convert和log_file_name_convert參數都是使用串替換的方式重命名的，通過將目標文件名的指定的字符串替換成指定的字符串，從而生成新的文件名
本次實驗中，hongye數據庫的數據文件存放在路徑為：/oracle/oradata/hongye/，而catdb的數據文件路徑為：/oracle/oradata/catdb/，所以只要將所有文件名中的hongye替換成catdb就可以了。

2、創建復制數據庫的相關目錄，包括adump、bdump、cdump、udump、oradata/catdb
[oracle@ORA10G dbs]$ cd /oracle/admin
[oracle@ORA10G dbs]$ mkdir catdb catdb/adump catdb/bdump catdb/cdump catdb/udump
[oracle@ORA10G dbs]$ ll /oracle/admin/
total 8
drwxr-xr-x? 7 oracle oinstall 4096 Feb 17 19:29 catdb
drwxr-x---? 8 oracle oinstall 4096 Feb 11 19:19 hongye
[oracle@ORA10G dbs]$ mkdir /oracle/oradata/catdb/
[oracle@ORA10G dbs]$ ll /oracle/oradata/catdb/
total 0
3、將ORACLE_SID設置為復制數據庫的sid，那么就不需要額外的配置復制數據庫的網絡文件了，前提是已經配置了目標數據庫的網絡配置文件，二者必須至少要配其一。
[oracle@ORA10G dbs]$ echo $ORACLE_SID
hongye
[oracle@ORA10G dbs]$ export ORACLE_SID=catdb
[oracle@ORA10G dbs]$ echo $ORACLE_SID
catdb
4、創建復制數據庫的密碼文件。
[oracle@ORA10G dbs]$ orapwd file=$ORACLE_HOME/dbs/orapwcatdb
Enter password for SYS:
5、登錄復制數據庫，以nomount方式打開數據庫。
[oracle@ORA10G dbs]$ sql
