Error description
There is a problem caused by the IPIC Capacity 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 the Capability Exchange Message sent to it by CICS Transaction Server. CICS Transaction Server has incorrectly formatted this message. Additional Symptom(s) Search Keyword(s): KIXREVWRW

Problem summary
**************************************************************** * 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.
