Use rman duplicate... from active database to create external uard (for each L

Use rman duplicate... from active database to create external uard (for oracle 11g) oracle 10g can implement external uard through the backup-based rman DUPLICATE, back up the DATABASE through steps, and restore the DATABASE on the standby side. At 11 GB, oracle introduced the Duplicate From Active Database technology, without the need to perform rman backup and recovery for the Database. All actions are automatically completed through the network. The following is a specific implementation example: primary db: hrdbprimstandby db: standby (because it is a three-node rac, the Instance name is standby1) www.2cto.com I. Environment preparations on the primary side: 1, ensure the database archiving status [SQL] SQL> select log_mode from v $ DATABASE; LOG_MODE ------------ ARCHIVELOG 2, Enable force logging [SQL] SQL> ALTER Database FORCE LOGGING; database altered. 3. Generate standby redolog [SQL] SQL> alter database add standby logfile '/oracle/app/oracle/oradata/hrdbprim/redo11.log' size 50 m; Da Tabase altered. 4. to modify the primary parameter file spfile, you must set the following eight parameters: [SQL] SQL> alter system set LOG_ARCHIVE_CONFIG = 'dg _ CONFIG = (hrdbprim, standby) '; www.2cto.com System altered. SQL> alter system set LOG_ARCHIVE_DEST_1 = 'location =/oracle/app/oracle/oradata/hrdbprim/VALID_FOR = (ALL_LOGFILES, ALL_ROLES) DB_UNIQUE_NAME = hrdbprim '; System altered. SQL> alter system set LOG_ARCHIVE_DEST_2 = 'service = standby LGWR ASYNC VALID_FOR = (ONLINE_LOGFILES, PRIMARY_ROLE) DB_UNIQUE_NAME = standby '; System altered. SQL> alter system set LOG_ARCHIVE_DEST_STATE_1 = ENABLE; System altered. SQL> alter system set FAL_SERVER = standby; System altered. SQL> alter system set FAL_CLIENT = standby; System altered. www.2cto.com SQL> alter system set DB_FILE_NAME_CONVERT = '/oracle/app/oracle/oradata/hrdbprim/', '+ DATA/standby/datafile/' scope = spfile; System Altered. SQL> alter system set LOG_FILE_NAME_CONVERT = '/oracle/app/oracle/oradata/hrdbprim/', '+ DATA/standby/onlinelog/' scope = spfile; System altered. 2. Modify SQL * net files to Ensure network environment preparation and communication between tnsping and listener. oraSID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = standby) (ORACLE_HOME =/oracle/app/oracle/product/11.2.0/db_1) (SID_NAME = standby3 ))) LISTENER = (DESCRIPTION = (ADDRESS = (PROTOCOL = T CP) (HOST = 10.4.124.235) (PORT = 1521) www.2cto.com tnsnames. ora hrdbprim = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 10.4.124.239) (PORT = 1521) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = hrdbprim ))) standby = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 10.4.124.235) (PORT = 1521) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = standby) (UR = A) 3. Create A standby database 1, pa Ssword password file. You can copy and rename the password from primary or generate a new one. The password must be consistent with the sys password. The copy method sftp... mv orapwhrdbprim orapwstandby2: Create a pfile file. Note that the pfile must be placed in the $ ORACLE_HOME/dbs directory.

Test the ADG result to restore the single node to the rac database and register it to the CRS. For more information, see the remarks in the previous article.
