Error description

  • An user application, using URIMAP with a PORT specification,
doesn't work anymore after migration from CICS TS 5.2 to
CICS TS 5.4. The PORT was defined with 47093, however the
traces showed that PORT 18443 was used.

Investigations showed that the port number is held in a
halfword. Before being converted to printable decimal
characters the port number is incorrectly loaded into a
register and sign extended. This causes the following
conversion to decimal to generate a negative number
when the original port number is over 32767 (x'7FFF').

Problem summary

  • ****************************************************************
* USERS AFFECTED: All CICS users                               *
****************************************************************
* PROBLEM DESCRIPTION: Incorrect port usage using a proxy      *
*                      server and URIMAP with port numbers     *
*                      higher than 32767.                      *
****************************************************************
An application, using URIMAP with a PORT number specification
greater than 32767 (x'7FFF') at CICS TS 5.4 and 5.5, fails
because port numbers above this value are converted incorrectly.

In addition, at CICS TS 5.5 only, an ABEND0C4 0C4/AKEX in module
DFHWBCL can occur.

Problem conclusion

  • DFHWBCL has been changed to convert high port numbers correctly
when using a proxy.
