Method, system and computer program for concurrent file update |
摘要 |
<p>A solution is proposed in a scheduler for updating a control file (220) storing a workload plan (defining a sequence of jobs to be executed during a production day). A handler (225) has exclusive write access to the control file (for updating information relating to the state of the jobs during execution of the plan). A planner (215) that needs to write a new plan into the control file (for the next production day) notifies the handler. In response thereto, the handler makes a copy (320) of the control file for use by the planner and starts logging (335) any update that it performs on the (original) control file. Once the planner completes its work, the handler applies the logged updates to the copy of the control file (as updated by the planner). The handler can now restart working on the copy of the control file, which then replaces its original version.
