错误处理“ORA-00257: archiver error”

上次在连接数据库的时候，遇到了如下错误：

$ sqlplus user/pass@TNSNAME

SQL*Plus: Release 10.2.0.1.0 - Production on Tue Jun 10 02:17:16 2008

Copyright (c) 1982, 2005, Oracle. All rights reserved.

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

Enter user-name:

从网上找了一下，可以用下面方法解决。

1、 检查。

sqlplus "/as sysdba"

SQL> select * from v$recovery_file_dest;

SQL> select * from v$flash_recovery_area_usage;

2、 删除过时的archive log 文件。

3、 使用RMAN。

$ rman

Recovery Manager: Release 10.2.0.1.0 - Production on Tue Jun 10 02:19:21 2008

Copyright (c) 1982, 2005, Oracle. All rights reserved.

RMAN> connect target xxxxdb

target database Password:
connected to target database: XXXXDB (DBID=3995198640)

RMAN> crosscheck archivelog all;
RMAN> delete expired archivelog all;
RMAN> exit

Recovery Manager complete.

4、重启instance。
