Situation Description

NetView managed DASD input and output rate of a task has reached an informational level.

 

Suggested Actions

I/O rate for the specified task has reached the informational value defined for this situation. The I/O rate might be high due to the following conditions:

  • A program loop (not necessarily on this task)
  • A program hang
  • Large volume of data processing
  • DFSMS problem
  • Unexpected I/O rate that exceeds best practices

Issue several TASKMON or TASKUTIL commands to see if the I/O rate is dropping. The TASKUTIL command shows the NetView command that is running on the task. If the I/O rate remains higher than best practices for an extended period of time, stop the task or notify the system programmer.

Notes:

  1. Consider increasing the informational threshold for the task if this situation continues to be triggered.
  2. Consider putting the TASKMON and TASKUTIL commands on a timer to monitor NetView task statistics.
