This message is part of a group of messages that VTAM® issues in response to the following commands:

• DISPLAY TRACES,TYPE=NODES,ID=(nodename1, nodename2,...,nodenamen)
• DISPLAY TRACES,TYPE=NODES,ID=*
• DISPLAY TRACES,TYPE=ALL

A complete description of the message group follows.

IST075I

• nodename is the name of the major or minor node that is associated with the trace data displayed in this message subgroup. If ID=* was entered on the DISPLAY TRACES command, nodename is a major node containing subordinate nodes with active traces.
• nodetype is the resource type of the major or minor node. See Node and ID types in VTAM messages for a description of nodetype.
  • If nodetype is CP, RESOURCE, or SSCP, nodename is a resource that may not yet be defined to VTAM. In this case, nodetype is the IDTYPE specified on the MODIFY TRACE command, and status in message IST1042I is always SAVED.

IST350I

• This message identifies the type of information shown in the display. Possible values are:

  TRACES,TYPE=NODES

  The display contains the status of the BUF, GPT, IO, LINE, SIT, and TG trace for a particular resource and its subordinate nodes.

  TRACES,TYPE=SMS

  The display contains the status of the SMS buffer trace.

  TRACES,TYPE=VTAM

  The display contains the status of the VTAM internal trace.

IST752I

• This message is displayed when the generalized PIU trace (GPT) is displayed for an independent LU. VTAM issues this message once for each adjacent link station (ALS) that the independent LU is using. VTAM issues this message only for adjacent link stations that exist in an NCP major node (or, for a switched connection, link stations that are connected through a link in an NCP major node).
• status is the trace status code. See the z/OS Communications Server: IP and SNA Codes for more information on resource status codes.
• alsname is the name of the adjacent link station that the independent LU is using.

IST1041I

• nodename can be one of the following:
  • The major or minor node displayed in message IST075I.
  • The name of a resource subordinate to the major or minor node displayed in message IST075I, if there is an active trace for that resource.
• nodetype is the resource type of nodename. See Node and ID types in VTAM messages for a description of nodetype.

IST1042I

• This message is always issued in this group except in the case when the GPT trace status is displayed for an independent LU. Then message IST752I is displayed.
• tracetype is the name of an active trace and can be one of the following:

  BUF

  Buffer contents trace

  GPT

  Generalized PIU trace (GPT)

  IO

  Input/output trace

  LINE

  Line trace

  SIT

  Scanner interface trace (SIT)

  STATE

  Resource state trace

  TG

  Transmission group (TG) trace

• status is the status of the displayed trace and can be one of the following:

  ON

  tracetype is BUF, IO, or STATE, and the trace is active for this resource.

  SAVED

  tracetype is BUF or IO, and the trace command is saved for this resource. This status is displayed when SAVE=YES was specified on the MODIFY TRACE command, and the resource has not yet been defined to VTAM.

  TRACT

  tracetype is GPT, LINE, SIT, or TG, and the trace is active for this resource.

  TRPAR

  tracetype is GPT, LINE, SIT, or TG, and the trace is in the process of being activated.

  For additional status information, see the z/OS Communications Server: IP and SNA Codes.

  TRPDR

  tracetype is GPT, LINE, SIT, or TG, and the trace is in the process of being deactivated.

  For additional status information, see the z/OS Communications Server: IP and SNA Codes.

  AMOUNT = value is displayed only if the buffer contents trace is active (tracetype is BUF) and indicates how much of the buffer's contents are traceable.

  • value represents the AMOUNT operand value specified on the TRACE start option or the MODIFY TRACE command, and can be one of the following:

    PARTIAL

    The trace record has a maximum size of 256 bytes including header information.

    FULL

    All of the buffer's contents are traceable.

    Note: If AMOUNT is not specified when the buffer contents trace is activated, the default value PARTIAL is displayed.

    See the z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures.

  SAVE = {YES|NO} indicates the value that was specified on the SAVE operand of the MODIFY TRACE command and is displayed only if the buffer contents, I/O, or resource state trace is active.

IST1422I

• This message is displayed if there are traces saved for resources that are not active. Messages IST1041I and IST1042I are displayed following this message for each resource.
• value is the value specified on the ID operand of the DISPLAY TRACES command. If TYPE=ALL was specified on the command, value is *.*.

IST2183I

• This message will only appear for a TRLE representing an OSA-Express2 or later Adapter and only when the OSA-Express2 or later adapter is armed for QDIOSYNC. See QDIOSYNC trace in z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for a description of the QDIOSYNC trace function.
• armstate is the OPTION operand value from the MODIFY TRACE command or TRACE start option.

  Tip: The OSA might be collecting more than what is specified here while OSA merges the options for all Armed data devices.

  Valid values are:

  ALLIN

  OSA is collecting inbound diagnostic data for all devices.

  ALLINOUT

  OSA is collecting inbound and outbound diagnostic data for all devices.

  ALLOUT

  OSA is collecting outbound diagnostic data for all devices.

  IN

  OSA is collecting inbound diagnostic data for devices defined to this VTAM.

  INOUT

  OSA is collecting inbound and outbound diagnostic data for devices defined to this VTAM.

  OUT

  OSA is collecting outbound diagnostic data for devices defined to this VTAM.

• syncid is the SYNCID operand value from the MODIFY TRACE command or TRACE start option. This value is to be used as part of a correlator when the OSA-Express2 or later diagnostic data is captured.
• saved_state is the SAVE operand value from the MODIFY TRACE command or TRACE start option. Valid values are YES or NO.
