Question

我在Glassfish服务器v3上与Oracle 12 DB一起在Windows Server 2012 64bit下的同一台机器上运行Java EE应用程序。我使用最新的ojdbc7驱动程序。

连接池配置：

<jdbc-connection-pool validation-table-name="DUAL" steady-pool-size="20" statement-cache-size="100" associate-with-thread="true" statement-timeout-in-seconds="30" idle-timeout-in-seconds="60" max-wait-time-in-millis="2000" validate-atmost-once-period-in-seconds="20" datasource-classname="oracle.jdbc.pool.OracleDataSource" pool-resize-quantity="5" max-pool-size="60" res-type="javax.sql.DataSource" name="dbPool" is-connection-validation-required="true">
  <property name="driverClass" value="oracle.jdbc.OracleDriver"></property>
  <property name="user" value="xxx"></property>
  <property name="url" value="jdbc:oracle:thin:@(DESCRIPTION=(ENABLE=BROKEN)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=orcl)))"></property>
  <property name="password" value="xxx"></property>
  <property name="portNumber" value="1521"></property>
  <property name="databaseName" value="orcl"></property>
  <property name="serverName" value="127.0.0.1"></property>
  <property name="oracle.jdbc.ReadTimeout" value="300000"></property>
  <property name="oracle.net.CONNECT_TIMEOUT" value="10000"></property>
</jdbc-connection-pool>

在2或3个小时后，当有超过1个用户（3-5）使用我的应用程序时，它会停止响应，我在glassfish日志中得到这个

javax.enterprise.resource.resourceadapter.com.sun.enterprise.resource.allocator|_ThreadID=152;_ThreadName=Thread-2;|RAR5038:Unexpected exception while creating resource for pool dbPool. Exception : javax.resource.spi.ResourceAllocationException: Connection could not be allocated because: IO Error: Socket read timed out
[...]

Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: IO Error: Socket read timed out

从数据库方面看起来像这样

当我只重置数据库监听器时，一切正常，接下来的1-2小时（取决于应用程序负载）。因此，临时解决方案是从Windows调度程序运行bat脚本，每隔1小时重置一次监听器。

我尝试了所有可以找到的东西 - 应用了这些参数：

- Sqlnet.ora:
SQLNET.INBOUND_CONNECT_TIMEOUT=180
SQLNET.EXPIRE_TIME=5
- Listener.ora:
INBOUND_CONNECT_TIMEOUT_LISTENER_IPC=120

但仍然没有成功
