OY64525: MSGIKT113I INVALID QUERY REPLY, TERMINAL ID: IS ISSUED DURING TSO LOGON.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• User receives MSGIKT113I during logon to TSO.  This results in
  the terminal being hung/hang.  During logon processing TSO/VTAM
  determined via the bind image that a READ PARTITION QUERY should
  be performed for either alternate screen size or language
  attributes. The device sent back 576 bytes of QUERY REPLY. The
  RECEIVE RPL has a length of 512 bytes, therefore when the QUERY
  REPLY was received it was truncated causing the invalid reply.
  

Local fix

• Change the LOGMODE table entry to reflect an alternate screen or
  remove LANG=xx so that TSO/VTAM will not need to query the
  terminal.

  This problem is described as follows:
    1. User tried to Logon to TSO.
    2. IKTXINIT received control to process the request. It
       established the session with the terminal. It also issued
       SEND macro to send the Write structured field (WSF) Read
       Partition Query to determine all of the terminal's
       characteristics. It then issued RECEIVE macro to receive
       the query reply with RPLAREA length of 512 bytes. The
       terminal responded with 576 bytes of data. IKTXINIT
       received part of the data from VTAM for the query reply.
       It didn't find the complete terminal characteristics in
       the incomplete query reply. This caused IKTXINIT to issue
       the message IKT113I invalid query reply.
  

Problem conclusion

• IKTXINIT and IKTMSIFR have been changed as follows:
     1. They will recognize if more than 512 bytes of query reply
        was received. If so, they will issue a GETMAIN macro to
        hold the large query reply area of more than 512 bytes.
     2. They will move the first 512 bytes of query reply in the
        large query area. They will issue RECEIVE macro to receive
        the rest of the query reply from VTAM.
     3. Then, they can process the complete query reply to
        determine the terminal characteristics. They will issue
        FREEMAIN to free the large query reply area.
