Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Clients issuing MQGET to get or browse * * a message receive MQRC_NOT_CONVERTED * * (MQRC 2119) when the message contains * * very large RFH2 headers. * **************************************************************** * RECOMMENDATION: * **************************************************************** After the client channel gets a message, rstSendAsyncMessage is called to send the message to the client. This routine segments the message based on the maximum transmission size for the channel (approx 32K for non-SSL channels/15K for SSL channels), and calls rriConvertValidate to convert the transmission to the client's encoding/ccsid, and validate the length of any headers in the message. If the message contains large RFH2 headers, causing the headers to span beyond the end of the first transmission segment, rriConvertValidate incorrectly determines that the header length is wrong, causing MQRC_NOT_CONVERTED to be returned.
Problem conclusion
rriConvertValidate is changed to no longer set MQRC_NOT_CONVERTED in this situation. 100Y CMQXRMCV
