Abstract: An approach is provided that receives an alteration request to mark a selected column in a database table as an unused column. A database control table is then updated to indicate that the selected column is unused. After the database control table is updated, when a read request is received for the selected column, the same data is returned for the selected column for each row being read and this data is not stored in the database table.

Abstract: An approach is provided in which a request addressed to a remote target node is transmitted through a network path with the network path includeing multiple relay nodes. The transmitting system recognizes that the transmission of the first request failed. Relay nodes in the serial path are analyzed using historical failure data. A first relay node is identified as a likely failed relay node based on the analysis. The first relay node is tested by transmitting a test request to the likely failed relay node. If the transmission of the test request fails, the identified likely failed node is verified by testing the previous node in the path. If verification is successful, the first node is selected as the failing node. However, if verification is unsuccessful, then a second node is chosen as the likely failed node and testing resumes.

Abstract translation: 提供了一种方法，其中通过包括多个中继节点的网络路径通过网络路径发送寻址到远程目标节点的请求。 发送系统识别出第一请求的发送失败。 使用历史故障数据分析串行路径中的中继节点。 基于分析，第一中继节点被识别为可能的故障中继节点。 通过向可能的故障中继节点发送测试请求来测试第一个中继节点。 如果测试请求的传输失败，则通过测试路径中的先前节点来验证所识别的可能的故障节点。 如果验证成功，则选择第一个节点作为故障节点。 然而，如果验证不成功，则选择第二个节点作为可能的故障节点并继续测试。
