Explanation
A user tried to log on to TSO/VTAM from terminal termid.
An error occurred that prevented a connection between the terminal
and TCAS. As a result, the terminal is about to be freed.
The
reason code is made up of three parts:
- aa
- Indicates the general reason that the message is being issued.
- 01
- CLSDST to terminal termid failed.
- 02
- INQUIRE device characteristics failed.
- 03
- INQUIRE session parameters failed.
- 04
- OPNDST to terminal termid failed.
- 06
- OPNDST to terminal termid failed when trying
to issue message IKT0020I to indicate that the maximum number of users
are logged on.
- 20
- GETMAIN for work area failed.
- 21
- Invalid session parameters.
- 22
- Invalid device characteristics.
- bb
- If an RPL-based macro failed, bb contains the
RPLRTNCD field in the RPL. Otherwise, it is 0.
- cc
- If an RPL-based macro failed, cc contains the
RPLFDB2 field in the RPL. Otherwise, it is 0.
If bb and cc are
not 0, see the z/OS Communications Server: IP and SNA Codes for a description of these codes.
If
an RPL-based macro failed, code is the sense code
and represents the RPLFDBK2 field in the RPL. Otherwise, it is 0.
If code is not 0, see the z/OS Communications Server: IP and SNA Codes for a description of code.
termid is
the terminal identifier. If VTAM® issues
a network-qualified name, termid is in the form netid.name.
System action
Processing continues, and TCAS tries to release
the terminal.
Operator response
If you VARY LOGON to TSO either by using
the VARY LOGON command or by specifying LOGAPPL=TSO in a definition
statement, a new logon attempt is made when the user session ends,
even if it ends in error. If this occurs, this message is issued
repeatedly with SENSE=0821. Enter the VARY NOLOGON command
to correct the situation.
Otherwise, save the system log for
problem determination.
System programmer response
Use the system log and the description
of
aabbcc and
code to assist
you in correcting the problem.
- If RC = 220000, this might indicate that FEATUR2=EDATS
is coded on the LOCAL definition statement for a channel-attached
non-SNA device. To correct this error, remove the FEATUR2 operand
from the LOCAL definition statement. Deactivate and reactivate the
major node to use the new definition. See the z/OS Communications Server: SNA Resource Definition
Reference for
additional information on coding the LOCAL definition statement and
the FEATUR2 operand.
- If RC = 061001, this might indicate that FASTPASS=NO should
be coded on the SLU definition statement so that the SLU can support
the type of session initiation required. See the section on common
subarea network problems, in the z/OS Communications Server: SNA Diagnosis Vol
1, Techniques and Procedures for more information about this problem.
