标题: RMAN备份出现RMAN-06214: Datafile Copy
备份命令发现报错：

report obsolete;

delete noprompt obsolete;

报错如下：

RMAN-06207: WARNING: 12 objects could not be deleted for DISK channel(s) due

2567 RMAN-06208: to mismatched status. Use CROSSCHECK command to fix status

解决方案：

crosscheck copy;

delete obsolete;

相关知识如下：

在用DELETE OBSOLETE 命令删除废弃的备份文件，如果出现如下错误（RMAN-06207 & RMAN-06208），那么需要用CROSSCHECK命令来解决：

RMAN-06207: WARNING: 2 objects could not be deleted for DISK channel(s) due
RMAN-06208: to mismatched status. Use CROSSCHECK command to fix status

CROSSCHECK命令用户核对备份文件，以确保RMAN资料库与备份文件保持同步。当执行该命令时，如果RMAN资料库记录的状态与实际备份文件不匹配，则会更新资料库里的状态使其与实际备份文件状态一致；若备份文件处于expired状态，那么说明该备份已失效，可以删除之；

常用命令介绍：

1.CROSSCHECK BACKUP

用于核对数据库、表空间、数据文件、控制文件、归档日志、SPFILE的备份集。

CROSSCHECK BACKUP ; --核对所有备份（包括有效和失效的备份）

CROSSCHECK BACKUP of database; --核对除控制文件、归档文件外的备份文件

CROSSCHECK BACKUP of tablespace system;

CROSSCHECK BACKUP of datafile 1;

CROSSCHECK BACKUP of controlfile;

CROSSCHECK BACKUP of archivelog all;

CROSSCHECK BACKUP of archivelog sequence 3;

CROSSCHECK BACKUP of spfile;

2.CROSSCHECK BACKUPPIECE

用于核对特定备份片，该命令需要制定备份片的BP值或备份片名称；

CROSSCHECK BACKUPPIECE 24;

CROSSCHECK BACKUPPIECE '/u01/app/Oracle/rman_backup/OCPYJG_28';

3.CROSSCHECK BACKUPSET

用于核对特定的备份集，该命令需要制定备份集的BP值；

CROSSCHECK BACKUPSET 24;

4.CROSSCHECK COPY

用于核对数据库、表空间、数据文件、控制文件、归档文件的映像副本（即备份是用COPY DATAFILE ...... 或BACKUP AS COPY ......DATAFILE......命令备份数据文件的映像）

CROSSCHECK COPY;

CROSSCHECK COPY of database;

CROSSCHECK COPY of tablespace system;

CROSSCHECK COPY of datafile 1;

CROSSCHECK COPY of controlfile;

CROSSCHECK COPY of archivelog all;

CROSSCHECK COPY of archivelog from sequence 24 until sequence 32;

5.CROSSCHECK DTAFILECOPY

用于核对特定的数据文件映像副本，该命令需要指定映像副本的文件名或KEY值；

CROSSCHECK DATAFILECOPY 2;

CROSSCHECK DATAFILECOPY '/u01/app/oracle/rman_backup/tp9.dbf';

6.CROSSCHECK CONTROLFILECOPY

用于核对特定的控制文件映像副本，该命令需要指定控制文件映像副本的文件名或KEY值；

CROSSCHECK CONTROLFILECOPY 3;

CROSSCHECK CONTROLFILECOPY '/u01/app/oracle/rman_backup/controlfile01.ctl;

7.CROSSCHECK ARCHIVELOG

用于核对特定的归档日志，该命令需要指定归档日志的文件名或KEY值或SEQUENCE值；

CROSSCHECK ARCHIVELOG 36;

CROSSCHECK ARCHIVELOG 'crosscheck archivelog '/u01/app/oracle/product/11g/dbs/arch1_6_813161833.dbf';

CROSSCHECK ARCHIVELOG sequence 7;
