oracle 归档日志满处理


网站无法访问，tomcat重启无效，检查错误日志error.log发现如下错误：

sed by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (ORA-00257: archiver error. Connect internal only, until freed.

)

原来是归档日志满导致的

果然空间都99.96%了。使用rman 把3天前的归档日志全部删除掉，网站正常。

rman>crosscheck archivelog all

rman> delete expired archivelog all;

rman>delete archivelog until time 'sysdate-3' ;
