本地有一个小的环境，今天照例登上sqlplus，突然发现报了如下的错误。一看原来归档满了。我记得前几天做一个批量操作临时把temp文件resize了很大，限于本地空间有限。准备改回去。把多余的归档删除了。
sqlplus n1/n1
....
ERROR:
ORA-00257: archiver error. Connect internal only, until freed.
这个时候sysdba的权限发挥作用了，它可以照常登录。然后开始做resize操作。
SQL> alter database tempfile '/u03/ora11g/oradata/TEST01/temp01.dbf' resize 100M;
但是等了好一会儿，一直没有输出。是不是Hang住了。
看来得删除归档文件了。然后到归档目录下尝试删除，结果这个时候rm似乎不管用了，命令执行了，但是归档文件还在那。我想是不是有系统级的问题了。
决定重启 ，重启以后，Mount状态过后就很不留情的报了一个03113的错误。

查看alert日志文件。看到重做日志归档失败。

因为是测试环境，所以采用了如下的方法，启动到Mount阶段之后
SQL> startup mount

这个时候重新执行temp文件的resize，就没有问题了。

Database altered.
