這篇文章主要介紹了數(shù)據(jù)庫(kù)中如何查看備份信息腳本，具有一定借鑒價(jià)值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓丸趣 TV 小編帶著大家一起了解一下。

查看某個(gè)備份集 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$RMAN_CONFIGURATION;
檢查某個(gè)時(shí)間段備份失敗的記錄：SELECT * FROM V$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%
查看備份成功的歷史記錄：
SELECT * FROM V$RMAN_STATUS
WHERE START_TIME = TO_DATE(START_TIME, YYYY-MM-DD HH24:MI:SS)
AND END_TIME = TO_DATE(END_TIME , YYYY-MM-DD HH24:MI:SS)
AND OPERATION = BACKUP
AND STATUS = COMPLETED
查看所有備份集詳細(xì)信息：
SELECT A.RECID BACKUP SET ,
A.SET_STAMP,
DECODE (B.INCREMENTAL_LEVEL,
, DECODE (BACKUP_TYPE, L , Archivelog , Full),
1, Incr- 1 級(jí) ,
0, Incr- 0 級(jí) ,
B.INCREMENTAL_LEVEL)
Type LV ,
B.CONTROLFILE_INCLUDED 包含 CTL ,
DECODE (A.STATUS,
A , AVAILABLE ,
D , DELETED ,
X , EXPIRED ,
ERROR )
STATUS ,
A.DEVICE_TYPE Device Type ,
A.START_TIME Start Time ,
A.COMPLETION_TIME Completion Time ,
A.ELAPSED_SECONDS Elapsed Seconds ,
A.BYTES/1024/1024/1024 Size(G) ,
A.COMPRESSED,
A.TAG Tag ,
A.HANDLE Path
FROM GV$BACKUP_PIECE A, GV$BACKUP_SET B
WHERE A.SET_STAMP = B.SET_STAMP AND A.DELETED = NO
ORDER BY A.COMPLETION_TIME DESC;

查看 RAMAN 備份工作細(xì)節(jié)
select start_time,
end_time,
input_type,
output_device_type,
status,
round(input_bytes / 1024 / 1024 / 1024) as intput_gb,
round(output_bytes / 1024 / 1024 / 1024) as output_gb
from v$rman_backup_job_details
where end_time sysdate – 3;

RMAN 進(jìn)度查詢
select case
when opname like %aggregate% then
total
else
opname
end opname,
trunc(sofar * 100 / totalwork, 2) || % progress,
units
from v$session_longops
where opname like RMAN%
and totalwork sofar;

關(guān)于 Oracle 數(shù)據(jù)庫(kù)的 RMAN 備份，除了郵件外，是否能通過其它方式檢查 RMAN 備份的成功與失敗呢？其實(shí)我們可以通過下面 SQL 腳本來(lái)檢查某個(gè)時(shí)間段備份失敗的記錄：

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%

查看備份成功的歷史記錄：

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 等幾種狀態(tài)。另外，如果你在命令窗口輸入

[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

RMAN

在 V$RMAN_STATUS 里面，你會(huì)看到插入了一條記錄 STATUS 為 RUNNING 狀態(tài)

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

此時(shí)如果在 RMAN 中隨意執(zhí)行一個(gè)錯(cuò)誤命令，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

RMAN /

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00558: error encountered while parsing input commands
RMAN-01006: error signalled during parse

clip_image001

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 WITH ERRORS

在 RMAN 中退出，此時(shí)你會(huì)看到 STAUS 記錄從 RUNNING WITH ERRORS 變成了 COMPLETED WITH ERRORS

clip_image002

也就是說(shuō)，你可以在這個(gè)視圖里面查看在 RMAN 里面執(zhí)行的一些操作, 例如刪除歸檔日志等，另外，如果要查看 RMAN 的輸出，可以查看 V$RMAN_OUTPUT，V$RMAN_OUTPUT 視圖記錄了 RMAN 生成的信息，這是在內(nèi)存中額視圖，不會(huì)記錄到控制文件上。最多有 37278 條記錄.

當(dāng)然也可以從 V$RMAN_BACKUP_JOB_DETAILS 中查看 RMAN 備份更詳細(xì)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，如果我們需要查看 RMAN 備份的一些詳細(xì)記錄，在惜分飛的通過 sql 查詢 rman 備份信息博客里面分享了下面一些經(jīng)典的 SQL 語(yǔ)句。收錄在此。

查看所有備份集詳細(xì)信息：

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;

查找某個(gè)備份集中包含數(shù)據(jù)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#;

查詢某個(gè)備份集中控制文件

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;

查看某個(gè)備份集中歸檔日志:

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#;

查看某個(gè)備份集 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;
