洋名字叫：ORA-12528: TNS:listener: all appropriate instances are blocking new connections

通过在CMD下用lsnrctl status 查看出的问题。

Listening Endpoints Summary...

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=lypch)(PORT=1521)))

(DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROCipc)))

Services Summary...

Service "LSExtProc" has 1 instance(s).

Instance "LSExtProc", status UNKNOWN, has 1 handler(s) for this service...

Service "ammicly" has 1 instance(s).

Instance "ammicly", status BLOCKED, has 1 handler(s) for this service...

The command completed successfully

注：ammicly 就是所谓的数据库实例。

上个图样。

显然我上面的图是正确的，而出错情况下为：

这个问题说明数据库没有Mount

连接数据库,发现:

ORA-12528: TNS:listener: all appropriate instances are blocking new connections

用sqlplus /nolog

sql>connect [email=sys/ammic@amicly]sys/ammic@amicly[/email] as sysdba

ORA-12528: TNS:listener: all appropriate instances are blocking new connections

连接的问题

1，可以通过修改listener.ora(该文件位于:{你的Oracle安装盘}:\app\administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN)的参数,把动态的参数设置为静态的参数,红色标注部分,然后从新启动监听,就OK

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = C:\oracle\product\10.1.0\db_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = ammicly)

(ORACLE_HOME = c:\oracle\product\10.1.0\db_1)

(SID_NAME = ammicly)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = lypch )(PORT = 1521))

)

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))

)

)

)

2，也可以通过修改tnsnames.ora文件(该文件位于:{你的Oracle安装盘}:\app\administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN)的参数,红色表注部分

# tnsnames.ora Network Configuration File: C:\oracle\product\10.1.0\db_1

\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

AMMICLY =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = lypch )(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = ammicly)

(UR=A)    )

)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

)

然后 sqlplus /nolog

SQL>alter database mount;

SQL>alter database open;

这样就可以启动数据库了;

或者用Oradim -shutdown -sid ammicly -shuttype srvc,inst -shutmode immediate -syspwd ammic;关闭数据库

在用oradim -startup -sid ammicly -starttype srvc,inst -syspwd ammic;启动数据库解决;也可以在截面上从启动数据库服务来解决;
