Informing the scheduler of unplanned changes in resources

Sometimes a vital resource suddenly becomes unavailable because:
  • A hardware error occurs on a tape or disk drive
  • A processor is down
  • A link is down
  • Important staff are not available
  • Resources must suddenly be reallocated.

When a vital resource becomes unavailable, you usually change the workstation definitions to prevent HCL Workload Automation for Z from starting operations in the wrong order or producing inaccurate schedules. If the resource is a special resource, refer to Monitoring special resources for details of the RESOURCE MONITOR panel. But to change workstation parallel servers and the workstation fixed (R1 and R2) resources, use the MODIFYING THE CURRENT PLAN panel and select the WORK STATIONS option to display a list of all workstations. Enter the S row command beside the workstation you want to select. You can then change the reporting attributes and the open interval information for the workstation. You can also change the alternate workstation for a workstation in this panel.

Any changes to open intervals that you make here remain in effect until they elapse or until you change them again in the panel. These changes always override the information calculated from the workstation descriptions when you extend the current plan.

Note: If you assign no parallel servers to an interval and specify that HCL Workload Automation for Z should control on servers for the workstation, HCL Workload Automation for Z will not submit any jobs for that workstation during the interval.
