RMAN-06059: expected archived log not found, loss of archived log compromises recoverability

归档日志被物理删除后执行rman操作报错：

RMAN> backup database plus archivelog;





Starting backup at 01-JUL-2015 12:55:59

current log archived

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

处理方法：（crosscheck 会将找不到的归档日志标记为expired状态）

RMAN> crosscheck archivelog all;

此外，可以查看一下归档日志的状态：

SQL> select sequence#, 2 name, 3 status, 4 decode(status,'A','available','D','deleted','U','unavailable','X','expired') 5 from v$archived_log; SEQUENCE# NAME S DECODE(STAT ---------- ---------------------------------------- - ----------- 4 /u01/app/oracle/oradata/yb1/redo01.log A available 5 /u01/app/oracle/oradata/yb1/redo02.log A available 6 /u01/app/oracle/oradata/yb1/redo03.log A available 4 /home/oracle/arch/1_4_882107304.dbf X expired 5 /home/oracle/arch/1_5_882107304.dbf X expired 6 /home/oracle/arch/1_6_882107304.dbf X expired 1 /home/oracle/arch/1_1_882110245.dbf X expired 2 /home/oracle/arch/1_2_882110245.dbf X expired 3 /home/oracle/arch/1_3_882110245.dbf A available 4 /home/oracle/arch/1_4_882110245.dbf A available 5 /home/oracle/arch/1_5_882110245.dbf A available 11 rows selected.

如果归档日志是被物理移动了位置，可以手动将归档日志注册进去：

RMAN> catalog start with '/xxx/xxx';#注册路径
RMAN> catalog archivelog '/home/oracle/arch/1_3_882110245.dbf';#注册具体归档日志
