主庫上的操作
強制日誌
Alter database force logging;
開啓歸檔，指定歸檔路徑
Shutdown immediate;
Startup mount;
Alter database archivelog;
Alter system set log_archive_dest_1 = ‘’;
Alter database open;
設置相關參數，通過pfile方式設置
create pfile='/home/oracle/pfile.txt' from spfile;
Shutdown immediate;
編輯pfile文件

這裏的名字就是對應pfile中參數service後面的服務名。
select name,remote_archive,database_role,guard_status,db_unique_name from v$database;
查看主狀態,是否已經就緒：

ORCL ENABLED PRIMARY NONE prim
備庫需要的相關文件
密碼文件
在主庫上：
生成：
[oracle@prim_new database]$ cd $ORACLE_HOME/dbs
[oracle@prim_new dbs]$ orapwd file=./orapw$ORACLE_SID password=oracle123 force=y
然後scp傳輸到備庫，需要在同一個目錄下：
[oracle@prim_new dbs]$ scp ./orapw$ORACLE_SID pdg.up.com:$ORACLE_HOME/dbs/
控制文件
在主庫上生成控制文件：
alter database create standby controlfile as '/u01/control01.ctl';
然後傳輸到與主庫同一個目錄下。由於備機上時安裝了與主機上完全相同目錄的數據庫，那麼只需要將原來的文件刪除保留目錄就行，先備機上（相應目錄上）刪除oradata下面的所有文件。
備機上：
Shutdown immediate;
主機上：
scp /u01/control01.ctl pdg_new.com:/u01/oracle/oradata/orcl/control01.ctl
scp /u01/control01.ctl pdg_new.com:/u01/oracle/fast_recovery_area/orcl/control02.ctl
其他核心文件
數據文件，redo，歸檔文件全部傳輸到備庫上，此時我將主庫處於mount狀態
主機上：shutdown immediate;
Startup mount;
Redo:
[oracle@prim_new orcl]$ scp *.log pdg_new.com:/u01/oracle/oradata/orcl/
Dbf:
[oracle@prim_new orcl]$ scp *.dbf pdg_new.com:/u01/oracle/oradata/orcl/
Archivelog:
[oracle@prim_new orcl]$ scp /u01/oracle/archivelog/*.arc pdg_new.com:/u01/oracle/archivelog/
Listener,tnsnames.ora
從主庫上傳輸給備機，並且適當修改
[oracle@prim_new orcl]$ cd /u01/oracle/product/11.2.0/network/admin/
[oracle@prim_new admin]$ ll

[oracle@prim_new admin]$ scp *.ora pdg_new:$ORACLE_HOME/network/admin/
Pfile
將主機上的pfile文件傳輸到備機
[oracle@prim_new admin]$ scp /home/oracle/pfile.txt pdg_new:/home/oracle/pfile.txt
oracle@pdg_new's password:
pfile.txt
修改pfile.txt:

啓動備庫到mount
備庫：startup pfile=’/home/oracle/pfile.txt’ mount
主機：alter database open;因爲剛纔是mount狀態
alter database set standby database to maximize availability;
完成後，在備庫上查看狀態：
SQL> select name,remote_archive,database_role,guard_status,db_unique_name from v$database;
NAME REMOTE_A DATABASE_ROLE GUARD_S DB_UNIQUE_NAME
--------- -------- ---------------- ------- ------------------------------

備庫開啓日誌應用
