PM98982: IPIC IPV6 ADDRESS IS NOT SENT PROPERLY IN CAPEX FROM CICS-TS TO TXSERIES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• There is a problem caused by IPIC Capability Exchange Message
  constructed by CICS Transaction Server. The calculation of the
  length of the LOGNAME subfield does not follow the design of
  IPIC protocol principles.
  When IPv6 is used, TXSeries properly follows IPIC protocol but
  can not parse Capability Exchange Message sent to it by CICS
  Transaction Server. CICS Transaction Server has incorrectly
  formatted this message.

  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: CICS TS failed to acquire IPCONN        *
  *                      to TXseries when IPv6 address is        *
  *                      used in tcpipservice.                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  In case IPv6 address is used in tcpipservice. When CICS TS
  send request to TXseries to acquire IPCONN, subfields logname
  and IPv6 address are built up in request message. The IPV6
  subfield is not placed immediately after the logname subfield.
  This caused the TXseries side to fail to locate the IPv6
  address.
  

Problem conclusion

• DFHISCO has been changed to generate the correct IPIC
  capability exchange CAPEX type 1 message.
