Built-in troubleshooting features

A list, brief description and links to more information on the tools and facilities which are built in to the product to facilitate troubleshooting.

IBM Workload Scheduler is supplied with the following features that assist you with troubleshooting:
  • Informational messages that inform you of expected events.
  • Error and warning messages that inform you of unexpected events.
  • Message helps for the most commonly-occurring messages. See IBM® Workload Automation: Messages and Codes.
  • A logging facility that writes all types of messages to log files, which you use to monitor the progress of IBM Workload Scheduler activities. See IBM Workload Scheduler logging and tracing using CCLog.
  • Various tracing facilities which record at varying levels of details the IBM Workload Scheduler processes for troubleshooting by IBM Software Support. See Difference between logs and traces for more details.
  • An auditing facility that provides an audit trail of changes to the IBM Workload Scheduler database and plan for use in both monitoring and troubleshooting. For more details, see the section about Auditing in the Administration Guide.
  • A configuration snapshot facility that you can use for backup, and also which provides IBM Software Support with configuration information when unexpected events occur. See Data capture utility.
  • A facility that automatically creates a First Failure Data Capture (ffdc) configuration snapshot if the failure of any of the key components can be detected by its parent component. See First failure data capture (ffdc).
  • An automatic backup mechanism of the Symphony file whereby each fault-tolerant agent and domain manager that receives a new Symphony file, automatically archives the previous Symphony to Symphony.last in the path <TWA_home/TWS/, so that a backup copy is always maintained. This permits viewing of the previous Symphony data in case there were any message updates on the job and job stream states that were lost between the agent and its master domain manager.
  • A problem determination capability available from the Dynamic Workload Console to determine why jobs that are ready to start, do not start and the solution. See Jobs in READY status do not start.
