聚合器級別的數據庫連接錯誤

Question

從部署在WAS上的代碼獲取以下錯誤：

org.springframework.messaging.MessageHandlingException: 
  error occurred in message handler [org.springframework.integration.aggregator.AggregatingMessageHandler#0]; 
nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: 
  Could not get JDBC Connection; 
nested exception is com.ibm.websphere.ce.cm.ConnectionWaitTimeoutException:
  Connection not available, Timed out waiting for 180000

Answer 1

使用com.ibm.ejs.j2c.PoolManager查找日志，建議您去WAS支持。 看起來您的連接池對於您的用例來說很小。 特別是有您的線索：
