[20171124]手工使用Seed_Database.dfb和Seed_Database.ctl建庫.txt

--//昨天看yueli34的帖子,連結http://www.itpub.net/thread-2094530-1-1.html,註解與說明來自連結,感謝yueli34操作提示.
--//自己測試看看:

1.建立引數檔案
--//建立引數檔案,目錄為$ORACLE_HOME/dbs:

$ cat /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/initseeddata.ora
db_name=seeddata
sga_target=1024M
control_files=/u01/app/oracle/oradata/ora11g/control01.ctl
compatible=11.2.0.4

$ mkdir -p /u01/app/oracle/oradata/ora11g/

--//啟動到nomount狀態進行驗證
$ export ORACLE_SID=seeddata

SYS@seeddata> startup nomount;
ORACLE instance started.

2.建立控制檔案
$ cd $ORACLE_HOME/assistants/dbca/templates

$ ls $ORACLE_HOME/assistants/dbca/templates  -l
total 301856

$ cp $ORACLE_HOME/assistants/dbca/templates/Seed_Database.ctl  /u01/app/oracle/oradata/ora11g/control01.ctl

$ ls -l /u01/app/oracle/oradata/ora11g/control01.ctl
-rwxr-xr-x 1 oracle oinstall 9748480 2017-11-23 10:43:13 /u01/app/oracle/oradata/ora11g/control01.ctl

3.註冊資料檔案備份集
--//註冊備份集Seed_Database.dfb:

RMAN> catalog start with '$ORACLE_HOME/assistants/dbca/templates/Seed_Database.dfb';
searching for all files that match the pattern $ORACLE_HOME/assistants/dbca/templates/Seed_Database.dfb

--//檢視備份集,可以看到一個相同的備份集有兩個copy。一個是控制檔案原有的,一個是catalog新註冊進去。其中原有是其實不存在
--//,可以透過crosscheck加delete去除。

3.開啟資料庫:

--// 補充測試open read only可以開啟.

SYS@seeddata> alter database open ;

SYS@seeddata> alter database open NORESETLOGS;

4.嘗試使用建立新控制檔案是否可行:

SYS@seeddata> alter database backup controlfile to trace ;
Database altered.

5.補充建立臨時檔案:
ALTER TABLESPACE TEMP ADD TEMPFILE '/u01/app/oracle/oradata/ora11g/temp01.dbf' REUSE;
--//這樣建立報錯.

$ touch /u01/app/oracle/oradata/ora11g/temp01.dbf
SYS@seeddata> ALTER TABLESPACE TEMP ADD TEMPFILE '/u01/app/oracle/oradata/ora11g/temp01.dbf' size 100m REUSE;
Tablespace altered.

6.最後yueli34想實現NORESETLOGS開庫,而原始的控制檔案本身是備份型別,如果能修改為當前,估計可以.
SYS@seeddata> select CONTROLFILE_TYPE from v$database ;
CONTROLFILE_TY
