磁盘空间不足导致日志不能归档

昨天我的数据库不知什么原因无故挂起，今天启动数据库报如下错误：

SQL>alter database open;

alterdatabase open

*

ERROR atline 1:

ORA-16014:log 3 sequence# 99 not archived, no available destinations

ORA-00312:online log 3 thread 1: '+DGROUP1/oralife/redo03.log'

重做日志不能归档，查看日志文件：

[oracle@simpleit ~]$ cd admin/oralife/bdump/
[oracle@simpleit bdump]$ tail  -20 alert_oralife.log

于是知道是asm空间不足的原因导致，这时可以登录rman删除无用的归档日志，来释放磁盘空间。这时便可以成功启动数据库。

RMAN> run{
2> delete archivelog until time 'sysdate-7';--删除7天前的无用的归档日志}

RMAN> crosscheck archivelog all;

RMAN> delete noprompt expired archivelog all;

[oracle@simpleit bdump]$ sqlplus / as sysdba
