Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users with PI82872 * **************************************************************** * PROBLEM DESCRIPTION: DFHWB0002 Severe Error X'0322' when * * processing a HTTP HEAD request for a * * static text file. * **************************************************************** A HTTP HEAD request is sent into CICS for a static text file. CICS has to perform codepage conversion of the file to determine the correct Content-Length value to return. PI82872 changed DFHWBSR to not actually read the file so the buffer used for the codepage conversion is unallocated and uninitialised. If the buffer contents get updated by a different task then the codepage conversion call can fail and a DFHWB0002 severe error code(x'0322') message and dump will be issued.
Problem conclusion
UI49481 UI49513 UI51818 UI53966 DFHWBSR has been updated to return the correct response to a HEAD request for binary and text static files.
