1. If all partitions are in a combo state where they are both sending and receiving data, then statistics cannot be collected. 如果所有分区都处于他们都在发送和接收数据的 combo 状态,那么统计信息就不能被收集。
2. For example, DB2 supports massively parallel processing (MPP) architecture and can run on a single partition (EE) or multiple partitions (EEE). 例如, DB2 支持大规模并行处理(MPP)构件,并能在单个分区(EE)或者多个分区(EEE)上运行。
