Abstract:
1. A method comprising steps of: determining dependency information for a first workload part that is a portion of a first workload executed relative to a first capture database server of a first database and a second workload part that is a portion of a second workload executed relative to a second capture database server of a second database different than said first database, wherein the dependency information indicates at least one workload unit in the second workload part depends on at least one workload unit in the first workload part even though the first workload part was executed independent of the second workload part; determining a simulation workload identifying a plurality of workload parts including the first workload part and the second workload part; after determining the dependency information and determining the simulation workload, determining modified dependency information associated with the simulation workload by, at least in part, modifying particular dependency information associated with a particular workload part of the plurality of workload parts to no longer indicate that the at least one workload unit in the second workload part depends on the at least one workload unit in the first workload part; replaying, to a single database server, the simulation workload according to the modified dependency information; wherein replaying the simulation workload comprises replaying at least a portion of the first workload part and a portion of the second workload part concurrently; and wherein the steps are performed by one or more computing devices.
