解决：

你的问题是oracle连机日志出现无法归档错误.数据没有打开。

主要是因为数据库没正常关闭或SQL语句出错造成数据线程停止所引起.

报错如下：

ORA-16038: log 2 sequence# 83 cannot be archived

ORA-19809: limit exceeded for recovery files

ORA-00312: online log 2 thread 1: '/oracle/app/oracle/oradata/jkdb/redo02.log'

处理方法,

请在SQLplus下运行

SQL> conn / as sysdba;

SQL> startup;

SQL> alter database clear unarchived logfile '/oracle/app/oracle/oradata/jkdb/redo02.log';

SQL> shutdown immediate;

SQL> startup;

SQL>看回信息最后应该是，才说明数据正常启动

Database mounted.

Database opened.

SQL> exit;

再启监听并查看

>lsnrctl start

>lsnrctl status
