LMT Bypass function for critical console displays

HPE would like to request consideration of the feasibility of providing a function/feature which will enable the customer site to instruct zTPF to bypass LMT queueing of critical console output/displays which can play an instrumental role in monitoring the state of system health and/or resource usage. This function would be especially helpful/needed during conditions which may result in the delayed transmission/delivery of critical console output from the console LMT queue.

    A TPF Operation Server solution to this requirement is available with APAR IT27988.
    With this enhancement, the TPF Operations Server internal buffer can grow dynamically to handle the high message traffic and shrink when the memory is not needed. The buffer can grow to enable the server to store a burst of messages from the z/TPF system. This provides more time for the slow clients to process their messages, and can reduce the slowdown on other TPF Operations Server clients and the host interface.

    This APAR also introduces a new option for you to specify whether a terminal address (TA) is critical. The critical TAs are clients that must receive all of their messages, such as prime CRAS, message logging and automation (RAVEN), because losing any messages affects the daily operation. The noncritical TAs are the clients that can lose messages without impacting their operations.

    IBM believes the latent responses are due to TOS. The focus will be on the TOS issues.
