Job Management Manager Components › Components › System Components

System Components

• Job executor (NSCHED.EXE), a detached process that executes jobs
• Job database, a collection of information that describes jobs on a node or cluster of nodes (VSS.DAT)
• DCL interface that includes both management commands and general commands (SCHEDULER$MANAGER.EXE)
• Motif interface, a workstation approach that provides a graphical interface for the manager (SCHEDULER$MOTIF.EXE)
• Special Days databases (SCHED$SD_CLASSES.DAT and SCHED$SD_RESTRICTIONS.DAT)
• Event-log report utility for logging job events (VSS_REPORTS.EXE)
• Program (RETRY.EXE) gets executed by the manager on regular intervals when an action is being retried. It runs regularly until the actions it is attempting (stored in RETRY.DAT) are successful, or the retry period expires.
• Detached process (SCHED_REMOTE.EXE) that listens for remote Job Management Manager actions, enabling the manager to work over a network. NODENAME_REMOTE.LOG is the output log file for SCHED_REMOTE_EXE.
• Detached process (SCHED$LISTENER.EXE) that listens for termination messages from the remote Executor
• Database repair utility (DB_UTILITY.EXE)
• Load Balance Groups configuration utility (SCHEDULER$CONFIG.EXE) that creates, edits, and deletes Load Balance Group definitions in the Load Balance Group database (UJM$LOAD_BALANCE_GROUPS.DAT) for customized load balancing in an OpenVMS cluster.
• CPU system rating utility (CPU_UTILITY.EXE) that displays the current system rating used in load balancing calculations.
