一次ora-12528 故障的解决办法

在clinet连接数据库时为提示： ora-12528 : message 12528 not found; product=RDBMS ; facility=ora 解决办法： （-）： 先连接到实例t1cdp1,然后shutdown abort,接着startup nomount(忘记了接下来是否执行了alter database mount),此时就退出了登陆,再次尝试登陆的时候就报错： SQL> conn iat/welcome@t1cdp1 ERROR: ORA-12528: TNS:listener: all appropriate instances are blocking new connections 1. cmd下面输入lsnrctl,查看当前实例所有监听器的状态 C:\>lsnrctl LSNRCTL for 32-bit Windows: Version 10.2.0.3.0 - Production on 20-JUN-2010 22:49:13 Copyright (c) 1991, 2006, Oracle.

The command completed successfully 可以发现instance t1cdp1是blocked的状态(不知道 T1CDP1_XPT这个后缀是什么意思)， 此时可以确定是监听器出错了。 2. 以sysdba身份登录 sqlplus \ as sysdba 查看发现当前状态为nomount(找到问题根源了).接下来加载 数据库 alter dababase mount; alter database open; 3. 此时再次尝试连接数据库，成功登陆 SQL> conn iat/welcome@t1cdp1 Connected. 小结：其实碰到这种错误，可以直接通过sqlplus \ as sysdba进入查看instance状态，而是用lsnrctl则是为了进一步验证而已。 方法（二） 关闭数据数据库，重新启动数据库即可。重新启动监听。
