Abstract: Database systems and methods are provided for identifying a change associated with an update to executable code resulting in test failure. One method involves calculating risk scores for different changes associated with the update based on change characteristics associated with the respective changes, identifying a change from among the different changes associated with the update based on the risk scores associated with the respective changes, generating a modified update to the executable code that includes the identified change and excludes remaining changes of the update from the modified update, and initiate execution of one or more tests with respect to a compiled version of the modified update to the executable code. When execution of the one or more tests against the modified update results in a test failure, the change is identified as a potential root cause of the test failure associated with the update.

Abstract: Embodiments disclosed herein provide a method and systems for monitoring and managing job resources for database tasks. A database is provided, wherein the database is associated with one or more computer systems that have a plurality of resources. Each resource in the plurality of resources has a capacity limit. Resource utilization by a plurality of active jobs is monitored. A waiting job is selected for initiation from a queue of one or more waiting jobs. If one or more resources required by the selected job are not available due to capacity limitations, one or more active jobs are notified that resource permissions have been revoked. Once the resources have been released, permission is granted to the selected job to consume the one or more resources, and the selected job is initiated.
