IST1015I
APPLICATION SUPPLIED parameter_name = parameter_value

Explanation

This message is part of a message group. The first message in the group is IST663I. See the explanation of that message for a description of the entire message group.

This message is the first of a subgroup of messages in the IST663I group of messages. A complete description of the message subgroup follows.
 IST1015I APPLICATION SUPPLIED parameter_name = parameter_value
[IST1028I parameter_value]

This message subgroup is issued only to the operator of the host of the secondary logical unit.

parameter_name is the name of the parameter displayed in the message subgroup, and is one of the following:
CPNAME
parameter_value displays the control point (CP) name of the type 2.1 peripheral node supplied by the application program for the switched connection.
GROUP NAME
parameter_value displays the name of a GROUP definition statement in the NCP or channel attachment major node that defines a group of SDLC switched links.
DIAL NUMBER
parameter_value displays the line number supplied by the application program for the switched connection. If parameter_value contains unprintable characters, the message will appear as follows:
IST1015I APPLICATION SUPPLIED DIAL NUMBER=X'parameter_value'

If the message contains any unprintable characters, the dial number is preceded by an "X". If the message contains only printable characters, the dial number is not preceded by an "X".

DLCADDR SUBFIELD
parameter_value displays the DLCADDR subfield supplied by the application program for the switched connection. If parameter_value contains unprintable characters, the message will appear as follows:
IST1015I APPLICATION SUPPLIED DLCADDR SUBFIELD=yy,X'parameter_value'

If the message contains any unprintable characters, the DLCADDR subfield is preceded by an "X". If the message contains only printable characters, the DLCADDR subfield is not preceded by an "X".

yy is the subfield ID.

DIRECT CALL LINE
parameter_value displays the name of the line supplied by the application program for the switched connection.
IDBLK/IDNUM
parameter_value displays the identification block (IDBLK) and identification number (IDNUM) supplied by the application program for the switched connection. IDBLK identifies the device type and IDNUM identifies the specific device or connection for the switched connection.
For IDBLK/IDNUM, parameter_value is 64 characters long; there are no spaces between the values of IDBLK and IDNUM. This field is always displayed in hex. VTAM® displays the first portion of parameter_value in message IST1015I and the remainder in message IST1028I. The message subgroup will appear as follows:
IST1015I APPLICATION SUPPLIED IDBLK/IDNUM=X'parameter_value
IST1028I parameter_value'

See the z/OS Communications Server: SNA Resource Definition Reference for more information on the IDBLK, IDNUM, and CPNAME operands for switched major nodes.

System action

The session initiation attempt fails.

Operator response

Save the system log for problem determination.

System programmer response

Use the information in messages IST663I, IST664I, and IST889I to determine the cause of the error. Possibilities include dial numbers not in the correct form or an XID failure. This is not necessarily a system programmer error. If it is not, notify the application programmer.
