oracle - UniversalConnectionPoolManagerMBean 已注册

Question

我有两个网络应用程序。
两者都使用oracle.ucp.UniversalConnectionPool。
当我在 JBoss 上部署这些应用程序时，出现以下异常:

java.sql.SQLException: Unable to start the Universal Connection Pool: java.sql.SQLException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: MBean exception occurred while registering or unregistering the MBean

数据源bean的定义:

<bean id="oracleDataSource" class="oracle.ucp.jdbc.PoolDataSourceFactory" factory-method="getPoolDataSource">
    <!-- hard coded properties -->
    <property name="connectionFactoryClassName" value="oracle.jdbc.pool.OracleDataSource" />
    <property name="validateConnectionOnBorrow" value="true" />
    <property name="connectionPoolName" value="ORACLE_CONNECTION_POOL" />
...
</bean>

有人知道如何解决这个问题吗？

Answer 1

两个池都尝试以相同的名称(“oracle.ucp.admin:name=UniversalConnectionPoolManagerMBean”)向 JMX 注册。

如果您turn off他们的 JMX 功能，一切应该工作得很好。
