Sense code 0821

Session parameters not valid: Session parameters included on a BIND were not valid or not supported by the half-session whose activation was requested. The session parameters are usually obtained from the logmode table entry.

Bytes 2 and 3 following the sense code contain sense-code-specific information.
0000
No specific code applies.
VTAM® hint: Possible causes of this error include, but are not limited to, the following ones:
  • Sessions cannot log on to CICS®.

    If this problem occurs, the sense code is displayed in message IST663I, and request is CINIT. When running CICS with AUTO-INSTALLATION, the terminal definition in the terminal control table terminal entry (TCTTE) must match the VTAM LOGMODE definition statement for the device. See the information about common subarea network problems in z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for more information about this problem.

  • The PLU has rejected the BIND session parameters.
  • The cryptographic function referenced in the logmode table entry is not active in all SSCPs involved in establishing the session.
0001
Mode name at LU not valid: The specified mode name was not recognized by the LU.
0002
Mode name at CP not valid: The specified mode name was not recognized by the CP.
VTAM hint: Possible causes of this error include, but are not limited to, the following ones:
  • A logon mode name was not specified when using dynamic reconfiguration to add a logical unit.
  • The logon mode name associated with the session request was not found in the specified mode table or in the default logon mode table (ISTINCLM).
    Verify that the requested logon mode name is defined in the following places:
    • In a subarea environment, the mode name must be defined in the SSCP of the secondary logical unit (SLU).
    • In an APPN environment, the mode name must be defined in the origin and destination nodes, as well as the servers of the origin and destination nodes (if the origin and/or destination is owned by an end node).
    • In a combined APPN and subarea environment, the mode name must be defined at the APPN node that owns the origin or destination, the server of that node (if it is an end node), and at the interchange node(s) that represents the subarea entry points.

      If the SLU is owned by a subarea node other than the interchange node representing the subarea entry point, the mode name must also be defined there.

    because mode table names are not carried on APPN line flows, a user-defined mode table is used only at the SSCP of the SLU. Other nodes defining the mode must define it in the default logon mode table. See z/OS Communications Server: SNA Network Implementation Guide for information about mode-to-class-of-service (COS) resolution in an APPN or combined APPN and subarea environments.
0003
The primary half-session requires cryptography, but the secondary half-session does not support cryptography.
0004
The secondary half-session requires cryptography, but the primary half-session does not support cryptography.
0005
Selective or required cryptography is specified, but no SLU cryptographic data key is provided.
0006
The BIND was rejected because it was non-negotiable and specified a primary send pacing window size larger than the SSCP or boundary function (BF) can handle, as determined by the logon mode entry or PACING/VPACING parameters.
0007
The specified mode name was not recognized in a subarea network.
000A
Specified mode table name not found at receiving CP.

VTAM hint: This sense code indicates that the mode table associated with the LU was not found. Verify that the specified table exists and activate it if necessary.

000B
The PLU requires message authentication code support, but it cannot be supported.
000C
The SLU requires message authentication code support, but it cannot be supported.
000D
The PLU requires Triple-DES but the SLU can provide only DES encryption.
000E
The SLU requires Triple-DES but the PLU can provide only DES encryption. The processor where the PLU is running does not have the Triple-DES chip installed.
