[数据库]ORACLE 查看RMAN的备份信息总结


    关于Oracle数据库的RMAN备份,除了邮件外,是否能通过其它方式检查RMAN备份的成功与失败呢?其实我们可以通过下面SQL脚本来检查某个时间段备份失败的记录:

SELECT * FROM V$RMAN_STATUS 
WHERE START_TIME >= TO_DATE(&START_TIME,'YYYY-MM-DD HH24:MI:SS')
  AND END_TIME   <= TO_DATE(&END_TIME  ,'YYYY-MM-DD HH24:MI:SS')
  AND OPERATION ='BACKUP'
  AND STATUS !='COMPLETED' 
  AND STATUS NOT LIKE 'RUNNING%'


 

查看备份成功的历史记录:

SELECT * FROM V$RMAN_STATUS 
WHERE START_TIME >= TO_DATE(&START_TIME,'YYYY-MM-DD HH24:MI:SS')
  AND END_TIME   <= TO_DATE(&END_TIME  ,'YYYY-MM-DD HH24:MI:SS')
  AND OPERATION ='BACKUP'
  AND STATUS ='COMPLETED'


 

其中STATUS主要有RUNNING、RUNNING WITH WARNINGS、RUNNING WITH ERRORS、COMPLETED、COMPLETED WITH WARNINGS、COMPLETED WITH ERRORS、FAILED等几种状态。另外,如果你在命令窗口输入

[oracle@MyDB ~]$ date
Tue Jul 19 10:52:02 CST 2016
[oracle@MyDB ~]$ rman target /
 
Recovery Manager: Release 10.2.0.5.0 - Production on Tue Jul 19 10:52:13 2016
 
Copyright (c) 1982, 2007, Oracle.  All rights reserved.
 
connected to target database: SCM2 (DBID=3990839260)
 
RMAN> 


 

在V$RMAN_STATUS里面,你会看到插入了一条记录STATUS为RUNNING状态

SQL> COL ROW_TYPE FOR A10;
SQL> COL OPERATION FOR A10;
SQL> COL COMMAND_ID FOR A20;
SQL> COL STATUS FOR A30;
SQL> COL OBJECT_TYPE FOR A16;
SQL> SELECT ROW_TYPE, COMMAND_ID, OPERATION, STATUS,OBJECT_TYPE 
  2  FROM V$RMAN_STATUS 
  3  WHERE START_TIME >= TO_DATE('2016-07-19 10:52:00', 'YYYY-MM-DD HH24:MI:SS');
 
ROW_TYPE   COMMAND_ID           OPERATION  STATUS              OBJECT_TYPE
---------- -------------------- ---------- ----------------- ----------------
SESSION    2016-07-19T10:52:13  RMAN       RUNNING


 

此时如果在RMAN中随意执行一个错误命令,如下所示

[oracle@MyDB ~]$ rman target /
 
Recovery Manager: Release 10.2.0.5.0 - Production on Tue Jul 19 10:52:13 2016

---------- -------------------- ---------- --------------------- ----------------
SESSION    2016-07-19T10:52:13  RMAN       RUNNING WITH ERRORS


 

 

在RMAN中退出,此时你会看到STAUS记录从"RUNNING WITH ERRORS"变成了"COMPLETED WITH ERRORS"

也就是说,你可以在这个视图里面查看在RMAN里面执行的一些操作,例如删除归档日志等,另外,如果要查看RMAN的输出,可以查看V$RMAN_OUTPUT,V$RMAN_OUTPUT 视图记录了RMAN生成的信息,这是在内存中额视图,不会记录到控制文件上。最多有37278条记录.

当然也可以从V$RMAN_BACKUP_JOB_DETAILS中查看RMAN备份更详细的信息。

SELECT START_TIME,
      END_TIME,
      OUTPUT_DEVICE_TYPE,
      STATUS,
      ELAPSED_SECONDS,
      COMPRESSION_RATIO,
      INPUT_BYTES_DISPLAY,
      OUTPUT_BYTES_DISPLAY
FROM V$RMAN_BACKUP_JOB_DETAILS
ORDER BY START_TIME DESC ;


 

另外,如果我们需要查看RMAN备份的一些详细记录,在惜分飞的通过sql查询rman备份信息博客里面分享了下面一些经典的SQL语句。收录在此。

 

查看所有备份集详细信息:

SELECT A.RECID "BACKUP SET",
       A.SET_STAMP,
        DECODE (B.INCREMENTAL_LEVEL,
                '', DECODE (BACKUP_TYPE, 'L', 'Archivelog', 'Full'),
                1, 'Incr-1级',
                0, 'Incr-0级',
                B.INCREMENTAL_LEVEL)
           "Type LV",
        B.CONTROLFILE_INCLUDED "包含CTL",
        DECODE (A.STATUS,
                'A', 'AVAILABLE',
                'D', 'DELETED',
                'X', 'EXPIRED',
                'ERROR')
           "STATUS",
        A.DEVICE_TYPE "Device Type",
        A.START_TIME "Start Time",
        A.COMPLETION_TIME "Completion Time",
        A.ELAPSED_SECONDS "Elapsed Seconds",
        A.BYTES/1024/1024/1024 "Size(G)",
        A.COMPRESSED,
        A.TAG "Tag",
        A.HANDLE "Path"
   FROM GV$BACKUP_PIECE A, GV$BACKUP_SET B
  WHERE A.SET_STAMP = B.SET_STAMP AND A.DELETED = 'NO'
RDER BY A.COMPLETION_TIME DESC;


 

查找某个备份集中包含数据文件

SELECT DISTINCT c.file#,A.SET_STAMP, D.NAME, C.CHECKPOINT_CHANGE#, C.CHECKPOINT_TIME
FROM V$BACKUP_DATAFILE C, V$BACKUP_PIECE A, V$DATAFILE D
WHERE A.SET_STAMP = C.SET_STAMP
    AND D.FILE# = C.FILE#
    AND A.DELETED='NO'
    AND c.set_stamp=&set_stamp
 ORDER BY C.FILE#;


 

查询某个备份集中控制文件

SELECT DISTINCT A.SET_STAMP,
                D.NAME,
                C.CHECKPOINT_CHANGE#,
                C.CHECKPOINT_TIME
 FROM V$BACKUP_DATAFILE C, V$BACKUP_PIECE A, V$CONTROLFILE D
 WHERE A.SET_STAMP = C.SET_STAMP
   AND C.FILE# = 0
   AND A.DELETED = 'NO'
   AND C.SET_STAMP = &SET_STAMP;


 

查看某个备份集中归档日志:

SELECT DISTINCT B.SET_STAMP,
                B.THREAD#,
                B.SEQUENCE#,
                B.FIRST_TIME,
                B.FIRST_CHANGE#,
                B.NEXT_TIME,
                B.NEXT_CHANGE#
 FROM V$BACKUP_REDOLOG B, V$BACKUP_PIECE A
 WHERE A.SET_STAMP = B.SET_STAMP
   AND A.DELETED = 'NO'
   AND B.SET_STAMP = &SET_STAMP
 ORDER BY THREAD#, SEQUENCE#;


 

查看某个备份集SPFILE

SELECT DISTINCT A.SET_STAMP, B.COMPLETION_TIME, HANDLE
FROM V$BACKUP_SPFILE B, V$BACKUP_PIECE A
 WHERE A.SET_STAMP = B.SET_STAMP
   AND A.DELETED = 'NO'
   AND B.SET_STAMP = &SET_STAMP;


 

查看RMAN的配置信息

SELECT NAME,VALUE FROM V$RMAN_CONFIGURATION;
