一.问题描述

因为空间不足导致无法归档，数据库hang住

Thu Jan 14 03:24:49 2021
ARC3: Error 19502 Closing archive log file '/oracle/ora11g/db/dbs/arch/1_74591_982339590.dbf'
Thu Jan 14 03:24:52 2021
ARC0: Error 19502 Closing archive log file '/oracle/ora11g/db/dbs/arch/1_74591_982339590.dbf'
ARC1: Error 19502 Closing archive log file '/oracle/ora11g/db/dbs/arch/1_74591_982339590.dbf'
ARC3: Error 19502 Closing archive log file '/oracle/ora11g/db/dbs/arch/1_74591_982339590.dbf'

二.解决方案

首先想到的是清理空间，不过由于早上上班在9:00左右才介入处理，而空间不足导致的归档报错从凌晨3点左右就开始的，清理的5G空间很快被归档日志给占用了。

好在此时数据盘用的是lvm，vg还剩余9G，此时增加了9G的空间

df -h
vgs
lvs
lvresize -l +9 /dev/mapper/vg_orcldb-lv_orcldb1
df -h
lvdisplay
resize2fs /dev/mapper/vg_orcldb-lv_orcldb1
df -h

2.1 清理归档日志

rman target /
delete noprompt archivelog all completed before 'sysdate-5';

结果报错:
RMAN-08137: warning: archived log not deleted, needed for standby or upstream capture process

2.2 问题分析

之前这个库是有备库的，不过公司业务缩减，要求服务器降配，前两周的刚刚把备库下线了
主库log_archive_dest_state_2已经设置为defer，主库alert日志查看也没有往备库传日志了。
但是归档居然删不掉

alter system set log_archive_dest_state_2=defer scope=both;
SQL>
SQL> show parameter  log_archive_dest_state_2;NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_state_2             string      DEFER
log_archive_dest_state_20            string      enable

itpub上正确取消dataguard的步骤
复盘了下，此次总共涉及下线3个备库
有1个备库我是按照下面步骤来的，然后shutdown了备库，后面系统组的同事下线的。
另外2个备库只修改了主库的 log_archive_dest_state_2 参数，并未调整备库，所以Oracle默认备库还存在。
导致删除这2个备库的报错，最终未删除，归档日志将磁盘撑爆，数据库hang住

On Standby DB:
i) SQL>alter database recover managed standby database cancel;
ii) SQL> alter system set log_archive_dest_state_2=DEFER;On Primary DB:i) SQL> alter system set log_archive_dest_state_2=DEFER;

2.3 最终解决方案

RMAN> delete noprompt force archivelog all completed before ‘sysdate-5’;
此为11g的bug，需要在delete后加上force关键字，metalink上有记载

RMAN-08137 When deleting archivelogs even when Streams CAPTURE does not require them [ID 1079953.1]In this DocumentSymptomsChangesCauseSolutionReferencesSymptoms
Applies To: 11gR1-11gR2RMAN is unable to delete archive logs from database even though they are not needed by CAPTURE process anymore.ChangesCause
In 11g, RMAN looks at MIN_REQUIRED_CAPTURE_CHANGE# in v$database and not at DBA_CAPTURE. By default this value is updated every 6 hours. So by default the value in v$database will be six hours behind the current value.Solution
Since changing frequency of update to MIN_REQUIRED_CAPTURE_CHANGE# in v$database can not be controlled, following workaround can be used:Archive log which are not needed by capture process can be deleted using:delete noprompt force archivelog all completed before 'sysdate-10/1440';
