面对UCP连接池的问题，其中所有者池将从该池获得连接的请求锁定为Runnable状态。下面是卡住的线程的堆栈跟踪。
从错误跟踪看，这似乎在从UCP池借用连接时被卡住了。我们还预期在oracle.ucp.jdbc.PoolDataSourceFactory上设置以下超时属性，以解决此问题。
connectionWaitTimeout 60
connectionProperties- oracle.net.CONNECT_TIMEOUT 6000 oracle.jdbc.ReadTimeout 300000
是否需要配置其他方法/超时来获取错误，如果客户端无法在一段时间内建立连接，而不是一直等待并在Runnable中阻塞线程？
还从JMX Mbean（oracle.uc.admin.UniversalConnectionPoomMBean）验证了池具有剩余容量，将其设置为100。那时borrwedConnectionCount为0，keepPoolCapacityCount为100，pendingRequestsCount继续为1。
