RMAN DELETE INPUT和DELETE ALL INPUT的区别

1.首先检查一下归档的路径

SYS@prod2 > show parameter archive

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
archive_lag_target                   integer     0
log_archive_config                   string
log_archive_dest                     string
log_archive_dest_1                   string      location=/home/oracle/app/arch
ive
log_archive_dest_10                  string
log_archive_dest_11                  string
log_archive_dest_12                  string
log_archive_dest_13                  string
log_archive_dest_14                  string
log_archive_dest_15                  string

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_16                  string
log_archive_dest_17                  string
log_archive_dest_18                  string
log_archive_dest_19                  string
log_archive_dest_2                   string      location=/home/oracle/app/fast
_recovery_area/prod2

有两个归档路径log_archive_dest_1，log_archive_dest_2

2.使用rman列出目标库的归档日志

RMAN> list archivelog all;

397     1    48      A 25-OCT-15
Name: /home/oracle/app/archive/1_48_892652515.dbf

398     1    49      A 26-OCT-15
Name: /home/oracle/app/archive/1_49_892652515.dbf

399     1    50      A 26-OCT-15
Name: /home/oracle/app/archive/1_50_892652515.dbf

400     1    51      A 27-OCT-15

401     1    52      A 27-OCT-15
Name: /home/oracle/app/archive/1_52_892652515.dbf

402     1    53      A 28-OCT-15
Name: /home/oracle/app/archive/1_53_892652515.dbf

403     1    53      A 28-OCT-15
Name: /home/oracle/app/fast_recovery_area/prod2/1_53_892652515.dbf

404     1    54      A 28-OCT-15
Name: /home/oracle/app/archive/1_54_892652515.dbf

405     1    54      A 28-OCT-15
Name: /home/oracle/app/fast_recovery_area/prod2/1_54_892652515.dbf

406     1    55      A 28-OCT-15
Name: /home/oracle/app/archive/1_55_892652515.dbf

407     1    55      A 28-OCT-15
Name: /home/oracle/app/fast_recovery_area/prod2/1_55_892652515.dbf

408     1    56      A 28-OCT-15
Name: /home/oracle/app/archive/1_56_892652515.dbf

409     1    56      A 28-OCT-15
Name: /home/oracle/app/fast_recovery_area/prod2/1_56_892652515.dbf

410     1    57      A 28-OCT-15
Name: /home/oracle/app/archive/1_57_892652515.dbf

411     1    57      A 28-OCT-15
Name: /home/oracle/app/fast_recovery_area/prod2/1_57_892652515.dbf

可以看到53之前的日志只有一个归档路径，之后的有两个归档路径

3.我们使用delete input看一下结果

RMAN> backup archivelog all delete input;

4.我们使用delete all input看一下结果
