Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: The reason text of message DFHSO0123 * * return code 446 is incorrect. * **************************************************************** * RECOMMENDATION: . * **************************************************************** The reason text of message DFHSO0123 return code 446 is 'TLS version mismatch'.

DFHMESOE has been changed to make sure the reason text of message DFHSO0123 return code 446 is 'TLS extension mismatch'. The CICS Transaction Server for z/OS Version 5 Release 3 CICS Messages and Codes Vol 2, manual should be changed in the description of message DFHSO0123 as follows: change the key words "TLS version mismatch" to "TLS extension mismatch"and change the line "47=TLS version mismatch" to "47=TLS extension mismatch". The same change should be made to the CICS Transaction Server for z/OS Version 5 Release 4 CICS Messages and Codes Vol 2, manual.
