Batch troubleshooting

The Batch Command Server can be subject to a wide variety of overall performance throughput. The performance factors considered here extend through:

• Usage and interpretation of the designed map or maps being executed by the Batch Command Server.
  • Internal functions used within the maps themselves.
• External factors that traditionally influence batch performance as a whole such as:
  • Input and output data sets and their corresponding block sizes.
  • Batch scheduling issues potentially impacting performance where it relates to potential resource contention and collisions.
  • Your system's environment's Workload Manager (WLM) policies and goals.

Some key areas targeted for improvement are:

• Excessive EXPS (I/Os)
• Excessive CPU Time Used
