Predefined views

The Historical Log Manager Performance workspace includes the following predefined views:

  • Historical Log Manager Performance The Historical Log Manager Performance view summarizes log manager performance activity for all your z/OS queue managers for a period of up to the past 24 hours. From this list you can select a queue manager whose log manager performance history you want to review. This log can be used to back out messages in an incomplete logical unit of work or to recover messages after queue manager or system failure. For best performance, you should eliminate contention for DASD log files, provide sufficient buffer and log file capacity, and maintain correct log buffer thresholds.
  • Reads/Writes This view displays, as a bar chart, the number of times the log is read from or written to per minute for the selected period of time.
