Abstract: Aspects of the present disclosure relate to managing concurrent updates on data. A transactional update on at least one record within a data set is detected. A log is generated for the transactional update, the log including an image of the at least one record within the data set before the transactional update. A batch update is detected. A determination is made whether the batch update collides with the transactional update by referencing the log. In response to determining that the batch update collides with the transactional update, a collision policy is referenced. A collision action indicated in the collision policy is then issued.

Abstract: A mechanism is provided for collecting one or more performance metrics. A plurality of source code instructions is provided. The source code instructions include a plurality of macro calls. Each of the plurality of macro calls includes a plurality of predetermined parameters. A plurality of object code instructions corresponding to the plurality of source code instructions is executed. In response to receiving a signal identifying at least one of the plurality of macro calls contained in the source code instructions and identifying a desired level of granularity, performance metrics are collected using the identified macro call in accordance with the desired level of granularity.
