  • oracle 数据库io 异常,错误代码17002 解决办法

    数据库使用一个月了,突然挂掉:错误代码17002 io异常:read timeout

    解决:

    1.登陆sql命令窗口

    [oracle@hostname ~]$ sqlplus /nolog

    SQL*Plus: Release 11.2.0.1.0 Production on Fri Aug 28 10:58:59 2015

    Copyright (c) 1982, 2009, Oracle.  All rights reserved.

    2.以管理员身份连接到数据库

    SQL> connect sys/oracle as sysdba
    Connected.

    3.关闭数据库实例
    SQL> shutdown abort        
    ORACLE instance shut down.
    SQL> exit
    Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
    With the Partitioning, Oracle Label Security, OLAP, Data Mining,
    Oracle Database Vault and Real Application Testing options

    4.查看监听并关闭
    [oracle@hostname~]$ lsnrctl status

    [oracle@hostname~]$ lsnrctl stop

    LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 28-AUG-2015 11:15:32

    Copyright (c) 1991, 2009, Oracle.  All rights reserved.

    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=iZ11gqfg6h1Z)(PORT=1521)))
    The command completed successfully

    5.重启监听
    [oracle@hostname~]$ lsnrctl start

    6.重启数据库

    [oracle@hostname~]$ sqlplus /nolog

    SQL*Plus: Release 11.2.0.1.0 Production on Fri Aug 28 11:30:25 2015

    Copyright (c) 1982, 2009, Oracle.  All rights reserved.

    SQL> connect / as sysdba
    Connected to an idle instance.
    SQL> startup
    ORACLE instance started.

    Total System Global Area 1486495744 bytes

    Redo Buffers            7884800 bytes
    Database mounted.
    Database opened.

    特别需要注意的是,一定要先启动监听服务,再启动数据库,否则还是连不上的。

    查看oracle 数据库服务:lsnrctl status
