ORA-00257: archiver error. Connect internal only, until freed——解决

参考http://www.2cto.com/database/201109/104615.html，

开启归档后，操作一个大表迁移表空间，执行了1个多小时没完成就手动给中断了，但是再次用plsql登陆时提示“ORA-00257: archiver error. Connect internal only, until freed”，原来是日志满了，根据上述网址提供的步骤操作后就可以，即删除部分归档日志。

1.首先查看当前flash recovery area使用情况

C:\windows\system32>sqlplus sys/fyzh@orcl as sysdba

已选择7行。

2.清除部分日志

采用rman方式清除日志

C:\windows\system32>rman target sys/fyzh

恢复管理器: Release 11.2.0.1.0 - Production on 星期三 9月 4 18:35:02 2013

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

连接到目标数据库: ORCL (DBID=1351232595)

RMAN> crosscheck archivelog all;  --先检查下

使用目标数据库控制文件替代恢复目录

分配的通道: ORA_DISK_1

通道 ORA_DISK_1: SID=68 设备类型=DISK

对归档日志的验证成功

归档日志文件名=E:\APP\FUYINZHEN\FLASH_RECOVERY_AREA\ORCL\ARCHIVELOG\2013_09_04\O1_MF_1_329_92FRDR8G_.ARC RECID=77 STAMP=825262239

对归档日志的验证成功

..........................................................

RMAN> delete expired archivelog all; --删除过期的日志，本库没有过期的

释放的通道: ORA_DISK_1

分配的通道: ORA_DISK_1

通道 ORA_DISK_1: SID=68 设备类型=DISK

说明与资料档案库中的任何归档日志都不匹配

--没有过期的，为了腾出空间，就指定到具体的时间将其删除。

RMAN>delete archivelog until time "to_date('2013-09-04 13:00:00','yyyy-mm-dd hh24:mi:ss')";

--删除后在看日志使用的空间情况，发现已使用的只有21.73%
