IST messages for VTAM network operators IST400I – IST799I

This chapter lists the VTAM® messages beginning with IST in the range of IST400I through IST799I. These messages can appear on a network operator’s console.

See Message text for VTAM operator messages for a list of the text of all VTAM operator messages.

Note: Messages that begin with the prefix ISTF are issued by the VTAM dump analysis tool and the VTAM internal trace (VIT) analysis tool. Help information is available as a part of each tool by pressing F1. Therefore, ISTF messages are not documented in z/OS Communications Server: SNA Messages. See z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for additional information.
