Predefined views
The Log Manager Performance workspace includes the following predefined views:
- Log Manager Performance The Log Manager Performance view summarizes log manager performance activity for all your z/OS queue managers. 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 appropriate 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.
- Archive This view shows the percentage of log reads that were resolved using an log archive data set.
- Delayed This view shows the percentage of log reads that were delayed because the MAXRTU data sets were already allocated.
For more information on the attributes listed in the tables of this workspace, see Managers attributes.
