12c中提供了基于网络的RMAN Restore和recover功能：
About Restoring Files Over the Network
RMAN restores database files, over the network, from a physical standby database by using the
FROM SERVICEclause of theRESTOREcommand. TheFROM SERVICEclause provides the service name of the physical standby database from which the files must be restored. During the restore operation, RMAN creates backup sets, on the physical standby database, of the files that need to be restored and then transfers these backup sets to the target database over the network.Use the
SECTION SIZEclause of theRESTOREcommand to perform a multisection restore operation. To encrypt the backup sets created on the physical standby database, use theSET ENCRYPTIONcommand before theRESTOREcommand to specify the encryption algorithm used.To transfer files from the physical standby database as compressed backup sets, use the
USING COMPRESSED BACKUPSETclause in theRESTOREcommand. By default, RMAN compresses backup sets using the algorithm that is set in the RMAN configuration. You can override the default and set a different algorithm by using theSET COMPRESSION ALGORITHMcommand before theRESTOREstatement.
About Recovering Files Over the Network
RMAN can perform recovery by fetching an incremental backup, over the network, from a primary database and then applying this incremental backup to the physical standby database. RMAN is connected as
TARGETto the physical standby database. The recovery process is optimized by restoring only the used data blocks in a data file. Use theFROM SERVICEclause to specify the service name of the primary database from which the incremental backup must be fetched.To use multisection backup sets during the recovery process, specify the
SECTION SIZEclause in theRECOVERcommand. To transfer the required files from the primary database as encrypted backup sets, use theSET ENCRYPTIONcommand before theRESTOREcommand to specify the encryption algorithm used to create the backup sets.To compress backup sets that are used to recover files over the network, use the
USING COMPRESSED BACKUPSET. RMAN compresses backup sets when it creates them on the primary database and then transfers these backup sets to the target
可以通过restore .. from service指定的对象类型：
- database
- datafile
- tablespace
- 控制文件
- SPFILE
当在主库Primary丢失/或损坏FILE#=6的user01.dbf数据文件时，可以直接使用restore datafile from service来从standby(其实并不要求一定是DataGuard,只需要是合适的备用库即可)上获得数据文件，例如：

具体的几种用法：
- 数据库级别： restore database from service <服务别名>
- 表空间： restore tablespace from service <服务别名>
- 控制文件： restore controlfile to ‘指定的位置’ from service <服务别名>
- SPFILE: restore spfile from service <服务别名>
通过recover .. from service命令可以通过网络将service指定的数据库的增量备份拉过来在本地做recover从而让本地数据库跟上远程数据库的SCN。
CONNECT TARGET “sys/<password>@standby as sysdba” RECOVER DATABASE FROM SERVICE primary;
此外上述增量备份还可以是基于压缩备份的：
SET COMPRESSION ALGORITHM ‘BASIC’;
SET COMPRESSION ALGORITHM ‘LOW’;
SET COMPRESSION ALGORITHM ‘MEDIUM’;
SET COMPRESSION ALGORITHM ‘HIGH’;
CONNECT TARGET “sys/<password>@standby as sysdba”
SET COMPRESSION ALGORITHM ‘BASIC’;
RECOVER DATABASE FROM SERVICE primary
USING COMPRESSED BACKUPSET;
In this practice you learn how to duplicate an active database in ASM to another disk group in ASM. ORCL is the active database that will be duplicated or cloned as DBTEST. The tasks include:• Use ASMCA to confirm sufficient disk space for the duplicated database.• Prepare the destination for the future DBTEST database with Oracle Net connectivity, password file, and a minimal initdbtest.ora file.• Confirm source database configuration settings.• Duplicate the ORCL database by using RMAN.• Test access to the cloned database.AssumptionsTwo terminal windows is open in the $LABS directory pointing to the orcl database instance. Work as the oracle OS user unless the task indicates the grid OS user.Tasks1. In a terminal window, log in as the grid OS user with oracle as training password and point your environment variables to the +ASM instance.$ su – gridPassword: oracle <<< not displayed$ . oraenvORACLE_SID = [grid] ? +ASMThe Oracle base has been changed from /u01/app/oracle to /u01/app/grid$2. Use the asmca utility to create the DISK2 disk group for your duplicate database.a. Enter asmca to start the utility which opens in a separate window.$ asmca b. Click Create and enter Disk Group Name: DISK2, click Redundancy: External (None), and select two available disks, and then click OK. c. Disk Group: Creation progress window may appear, followed by a success message. Click OK.d. Your new disk group is displayed on the Disk Groups tabbed page. e. Click Exit, and then Yes to confirm your exit.3. Continue as oracle OS user pointing to the orcl instance. Prepare Oracle Net connectivity with the netca utility. Add a dbtest entry to the tnsnames.ora file.$ netcaa. On the Oracle Net Configuration Assistant: Welcome page, select Local Net Service Name configuration and click Next.b. Confirm that Add is selected and click Next.c. Enter dbtest as Service Name and click Next.d. Select TCP as protocol and click Next.e. Enter your host and domain name (for example, edRSr39p1.us.oracle.com) in the Host name field. If you car unsure about the format, execute the command in the next step to view currently active examples.f. Confirm that Use the standard port number of 1521 is selected and click Next. g. Select No, do not test, because your dbtest instance does not yet exist, and click Next.h. Confirm dbtest as Net Service Name and click Next.i. Answer No to the question: Would you like to configure another net service name and click Next.j. You should see the message: Net service name Configuration Complete! Click Next.k. Click Finish.$ netcaOracle Net Services Configuration:Default local naming configuration complete. Created net service name: dbtestOracle Net Services configuration successful. The exit code is 0$4. Pointing to the ORCL instance, view the DBTEST entry in the $ORACLE_HOME/network/admin/tnsnames.ora file.$ cat $ORACLE_HOME/network/admin/tnsnames.ora# tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora# Generated by Oracle configuration tools.$ cat $ORACLE_HOME/network/admin/tnsnames.ora# tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora# Generated by Oracle configuration tools.RCAT = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = edRSr39p1.us.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = rcat) ) )DBTEST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = edRSr39p1.us.oracle.com)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = dbtest) ) )ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = edRSr39p1.us.oracle.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) ) $5. Comparing the DBTEST entry with the ORCL configuration, your notice that (SERVER = DEDICATED) is missing. a. Update the tnsnames.ora file with the gedit or vi editor so that the ORCL and DBTEST configurations follow the same pattern.$ gedit $ORACLE_HOME/network/admin/tnsnames.ora b. After you finished your edit, confirm that the entry is now:…DBTEST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = edRSr39p1.us.oracle.com)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = dbtest) ) )6. Copy the file into the equivalent grid home directory, /u01/app/grid/product/12.1.0/grid/network/admin in this example.$ cp /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora /u01/app/grid/product/12.1.0/grid/network/admin/tnsnames.ora$7. Create a password file for the future DBTEST database to allow OS authentication.a. As oracle OS user, point the environment variables to the dbtest instance.$ . oraenvORACLE_SID = [orcl] ? dbtestORACLE_HOME = [/home/oracle] ? /u01/app/oracle/product/12.1.0/dbhome_1/The Oracle base for ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1/ is /u01/app/oracle$ b. Create the $ORACLE_HOME/dbs/orapwdbtestfile with the orapwd utility.$ orapwd file=$ORACLE_HOME/dbs/orapwdbtest entries=15 password=oracle_4U$c. Optionally, confirm that the file exists.$ ls $ORACLE_HOME/dbs/*ora*/u01/app/oracle/product/12.1.0/dbhome_1//dbs/init.ora/u01/app/oracle/product/12.1.0/dbhome_1//dbs/orapwdbtest/u01/app/oracle/product/12.1.0/dbhome_1//dbs/orapworcl/u01/app/oracle/product/12.1.0/dbhome_1//dbs/orapwrcat/u01/app/oracle/product/12.1.0/dbhome_1//dbs/pfileorcl.ora/u01/app/oracle/product/12.1.0/dbhome_1//dbs/spfileorcl.ora/u01/app/oracle/product/12.1.0/dbhome_1//dbs/spfilercat.ora/u01/app/oracle/product/12.1.0/dbhome_1//dbs/spfileukoA.ora$8. In the same directory, create a minimal initdbtest.ora file with the following entries: db_name=dbtest remote_login_passwordfile=exclusiveThen confirm your content with the cat command.$ vi $ORACLE_HOME/dbs/initdbtest.ora $ cat $ORACLE_HOME/dbs/initdbtest.ora db_name=dbtest remote_login_passwordfile=exclusive$9. Point environment variables to the dbtest instance (as shown in step 7 a). Log in to SQL*Plus as SYSDBA, start the dbtest instance in NOMOUNT mode with the initdbtest.ora file. Then exit.$ . oraenvORACLE_SID = [dbtest] ?

In your cloning session set the $TNS_ADMIN environment variable as oracle OS user, because the server processes will try to resolve the AUXILIARY service name by using $TNS_ADMIN/tnsnames.ora.$ export TNS_ADMIN=/u01/app/grid/product/12.1.0/grid/network/admin$ echo $TNS_ADMIN/u01/app/grid/product/12.1.0/grid/network/admin$12. Use RMAN to duplicate the ORCL database as DBTEST database.Note that for the target and catalog, the service names are used, but NOT for the auxiliary connection.
