  • 使用RMAN备份Tablespace

    1、查看Tablespace信息

    SQL> desc dba_tablespaces
     Name                                      Null?    Type
     ----------------------------------------- -------- ----------------------------

     STATUS                                             VARCHAR2(9)
     CONTENTS                                           VARCHAR2(9)
     LOGGING                                            VARCHAR2(9)

     PLUGGED_IN                                         VARCHAR2(3)
     SEGMENT_SPACE_MANAGEMENT                           VARCHAR2(6)
     DEF_TAB_COMPRESSION                                VARCHAR2(8)
     RETENTION                                          VARCHAR2(11)
     BIGFILE                                            VARCHAR2(3)
     PREDICATE_EVALUATION                               VARCHAR2(7)

     COMPRESS_FOR                                       VARCHAR2(12)
    SQL> select tablespace_name,contents from dba_tablespaces;
    
    TABLESPACE_NAME                CONTENTS
    ------------------------------ ---------
    SYSTEM                         PERMANENT
    SYSAUX                         PERMANENT
    UNDOTBS1                       UNDO
    TEMP                           TEMPORARY
    USERS                          PERMANENT
    EXAMPLE                        PERMANENT
    EXPIMP                         PERMANENT
    
    7 rows selected.

     2、执行tablespace(example,users)备份

    RMAN> backup tablespace example,users format '/u01/arcerzhang/tb_exampleAndUsers_%U';
    
    Starting backup at 23-MAR-13
    using channel ORA_DISK_1
    channel ORA_DISK_1: starting full datafile backup set
    channel ORA_DISK_1: specifying datafile(s) in backup set
    input datafile file number=00005 name=/u01/oradata/poli/example01.dbf
    input datafile file number=00004 name=/u01/oradata/poli/users01.dbf
    channel ORA_DISK_1: starting piece 1 at 23-MAR-13
    channel ORA_DISK_1: finished piece 1 at 23-MAR-13
    piece handle=/u01/arcerzhang/tb_exampleAndUsers_0do59h7e_1_1 tag=TAG20130323T232325 comment=NONE
    channel ORA_DISK_1: backup set complete, elapsed time: 00:00:55
    Finished backup at 23-MAR-13
    
    Starting Control File Autobackup at 23-MAR-13
    piece handle=/u01/flash_recovery_area/POLI/autobackup/2013_03_23/o1_mf_n_810861862_8nvl99fg_.bkp comment=NONE
    Finished Control File Autobackup at 23-MAR-13
