Various embodiments provide process run-time prediction for processes running on server computers. In one embodiment, process run-time of a process is determined by building a database with a history of users, command lines and runtime associated with each command line, and comparing the process with stored records of completed processes in the database. In some embodiments, in response to a determination that the time interval of a process is likely to intersect a planned maintenance period on a server computer, a maintenance notification can be sent to a user of the process and therefore allow the affected process to be migrated to unaffected server computer(s).
