Improve maintenance window management

JobScheduler improves support for maintenance windows

Current Situation

• No standard functionality is provided with the JobScheduler release.
• Individual solutions are provided based on project work, see Maintenance Window Management

Functional Requirements

• Accuracy of maintenance windows to be precise for hh:mm
• Consideration of start times during maintenance windows
  • Suppress execution during a maintenance window
  • Move start time
    • Anticipate execution to an earlier point in time before the maintenance window
    • Postpone execution to a later point in time after completion of the maintenance window
• Scope
  • Jobs and Job Chains
    • Consider a critical path of essential jobs that should be executed during maintenance window
    • Select a number of jobs and job chains to be subject to maintenance window
      • select jobs and job chains by folder
      • select jobs and job chains by regular expressions of job names and job chain names
  • File Order Sources
    • No orders are created from file order sources during maintenance windows
  • Agents
    • Job execution for specific sets of Agents should be paused
  • Servers/Mandators
    • SSH jobs that are executed for a specific set of servers should be paused including JITL SSH jobs and shell jobs for SSH
    • Jobs that are assigned to specific mandators, e.g. based on folders or naming conventions should be paused
• Manage different types of maintenance windows
  • Group types of start time considerations and selected jobs and job chains into different maintenance types
    • e.g. standard maintenance window every last thursday of the month between 6pm and 10pm; this maintenance type would allow jobs of the critical path to be executed
    • e.g. deployment maintenance window every three months every last saturday from 6am to 6pm; this maintenance type would deny any jobs to be executed as the system is updated and applications are deployed
  • Manage groups of maintenance windows individually per client
    • e.g. client configures groups individually based on the above criteria for consideration of start times and scope of selection
    • e.g. client handles permissions for the management of maintenance window groups
• Planning of maintenance windows
  • Plan maintenance windows for future dates including start date and end date (some months in advance)
  • Create ad hoc maintenance windows, e.g. for emergency changes
  • Manage maintenance windows (CRUD operations: create, retrieve, update, delete)

Usability Requirements

• Make planned maintenance windows visible
  • point in time and duration of planned maintenance
  • jobs and job chains concerned by planned maintenance
• JOC interface for CRUD operations on maintenance windows
• Support ad hoc operations for starting and stopping maintenance windows
