Error description
Additional header chain validation
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1 and Release 1 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Invalid header chaining causes headers * * to be ignored. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a message containing multiple headers is put to a queue CSQMCHKM will validate the headers are in the correct format, however if the Format field used to identify the next header is in the incorrect ccsid, any following headers are ignored and treated as message data. This behaviour is correct, however it is not always straight forward to identify the origin of a message with incorrect header chaining.
Problem conclusion
A tunable parameter is added to enable additional validation of the format field in each header to verify it is in the correct ccsid. This parameter is intended for diagnostic purposes only, and should only be enabled under direction from IBM service personnel. 010Y 100Y CSQIRECP CSQMCHKM
