This z/VSE user configured a session between VTAM and PU2.0 through OSA-Express and XCA major nodes. When the PU2.0 sent a connection request , with the PU status in VTAM not CONCT, VTAM issued error messages IST690I, IST081I, and IST314I, as shown below:. IST690I CONNECTION REQUEST DENIED - INVALID STATION ID = stationid IST081I LINE NAME = linename, LINE GROUP = groupname, MAJNOD = nodename IST314I END

A problem occurred during implementation of a PU5 to PU5 APPN connection cross network between a VSE VTAM configured as a BN and ICN, running with the InterEnterprise VTAM function set, and a z/OS Communications Server VTAM. On the VSE VTAM host, a VARY ACT command for the switched major node failed, as shown below: [<pre> v net,id=switched_major_node,scope=all,act AR 0015 1C39I COMMAND PASSED TO ACF/VTAM<br> F3 0003 IST097I VARY ACCEPTED<

Why can I not use password phrases (passwords longer than 8 characters) or mixed-case passwords on the VTAM logo when logging onto z/VM 5.3 or later with password phrase support enabled?

Cross-domain session between two VTAM hosts connected by ESCON CTC point to point could not be established during VTAM start-up. The session setup fails with sense code 081E0000 on message IST475I. The session was recovered by V NET,ACT,ID=CDRM01 or ID=CDRM02 from either system.

High CPU utilization is seen occurring in VTAM module ISTCSCRJ. This can result in poor response time. This problem is particularly noticeable when large numbers of users are logging on or logging off.

These messages were displayed when VTAM was started: [<pre>] IST049I VTAM START REJECTED - OPEN FOR CP ACB FAILED IST1218I ACB ERROR FIELD = 72 IST314I END

At IPL time, we receive the following messages: . IEC130I TRSDB DD STATEMENT MISSING IST1288I TOPOLOGY DATASET RETRIEVAL WAS NOT SUCCESSFUL, CODE = 2 IEC130I DSDBCTRL DD STATEMENT MISSING IEC130I DSDB1 DD STATEMENT MISSING IEC130I DSDB2 DD STATEMENT MISSING

If you suspect that a non-terminating loop is occurring during VTAM processing, you will need to collect some basic diagnostic information before canceling the VTAM partition. The diagnostic information will assist the VTAM support team in diagnosing the problem. VTAM's failure to respond to a VTAM operator command may be an indication of a non-terminating loop.

This message appears on the operator console: IST967I DSPSERV CREATE FAILED FOR dataspace: RC=08 RS=00000900 What does this message mean?

During VTAM activation or normal operation, the following messages appear: IST1020I INSUFFICIENT STORAGE-DATA SPACE dspname FULL IST967I DSPSERV CREATE FAILED FOR dspname; RC=08 RS=00000500
