【转】 升级oracle RAC后出现ORA-12520错误

OracleSQLSQL ServerHTML

现象：

oracle10gR2.0.0.1升级后，现在客户端连接时报ORA-12520错误

12520, 00000, "TNS:listener could not find available handler for requested type of server"

// *Cause: None of the known and available service handlers for requested type

// of server (dedicated or shared) are appropriate for the client connection.

// *Action: Run "lsnrctl services" to ensure that the instance(s) have

// registered with the listener and that the appropriate handlers are

// accepting connections.

解决：

在网上找了资料后修改了下面的参数后正常：

SQL> alter system set local_listener = '(ADDRESS=(PROTOCOL=TCP)(HOST=172.0.2.62)(PORT=1521))'

2 scope = spfile sid = 'rac11g1';

系统已更改。

SQL> alter system set local_listener = '(ADDRESS=(PROTOCOL=TCP)(HOST=172.0.2.63)(PORT=1521))'

2 scope = spfile sid = 'rac11g2';

系统已更改。

SQL> shutdown immediate数据库已经关闭。已经卸载数据库。

ORACLE 例程已经关闭。

SQL> startup

ORACLE 例程已经启动。

Redo Buffers 4431872 bytes数据库装载完毕。数据库已经打开。

另外的节点也重启数据库服务器。

SQL> conn system/test@rac已连接。

问题解决。

参考：http://www.svn8.com/sql/Oracle/2009110712446_3.html

另外：在打数据库补丁后，在启动数据库时遇到了下面的错误：

SQL> startup

ORA-00119: invalid specification for system parameter LOCAL_LISTENER

ORA-00132: syntax error or unresolved network name 'LISTENER_GE02'

解决方法如下：

1、关闭数据库；

SQL> shutdown abort

ORACLE instance shut down.

2、然后在修改/opt/oracle/product/10.2.0/network/admin/tnsnames.ora文件，添加下面的语句：

LISTENER_GE02 =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

3、然后重新启动数据库

SQL> startup

ORACLE instance started.
