RMANgt; show all; CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; 在Oracle10g 11g 中 归档删除策略 缺省是没有配置的; 那么

RMAN> show all;

CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;

在Oracle10g 11g 中  归档删除策略 缺省是没有配置的;

那么这时去删除未应用过的的归档日志会是怎么一种情况:

RMAN> delete archivelog all;

released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=60 device type=DISK
RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process

archived log file name=/u01/app/ora11/flash_recovery_area/1_2019_822927217.dbf thread=1 sequence=2019
RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process

archived log file name=/u01/app/ora11/flash_recovery_area/1_2023_822927217.dbf thread=1 sequence=2023
RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process

Oracle 抛出报警;warning 归档日志没有删除,归档日志需要用作standby 或者 stream 捕获进程使用

关于rman中这个配置策略:

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY

不是自动删除归档。而是删除的时候确认归档已经被DATA GUARD、流环境所应用。这个功能的目的是避免删除其他功能所需要的归档日志。

如果配置归档删除策略:

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/db_home/dbs/snapcf_oradb1.f'; # default

尝试删除归档日志:
RMAN>  delete archivelog all;


released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=27 instance=oradb1 device type=DISK
