Error description
A Web Service requests fails with following indications when using a large container (170MB) and more than 2067 TextContent elements: Messages: --------- DFHPI1010 XML GENERATION FAILED. A CONVERSION ERROR (INVALID CHARACTER) OCCURRED WHEN CONVERTING. DFHAP0002 A SEVERE ERROR (CODE X'4E13') HAS OCCURRED IN MODULE DFHAPCR. Trace: ------ PI 0F08 PIII *EXC* CONVERSION_ERROR INVALID_CHARACTER TextContent PI 1008 PITL *EXC* PARSE_ICM_FAILED PROCESS_SOAP_REQUEST AP 4E13 APCR *EXC* Bad_Container_Eye-catcher IMPORT_ALL,SIBUS The DFHAPCR problem is caused by DFHRZSO not copying enough data into the reply buffer when called for RECEIVE_REPLY. This is an instore request stream linking tasks XXXXX and YYYYY. Task YYYYY has a copy of the data in an RZSVAREA buffer starting at 51000000 and also an RZISBUFF starting at 5B300000. The RZISBUFF is passed directly back to task XXXXX. The content of these storage areas at the time of the dump is correct. There is no missing data. Task XXXXX should copy the data it needs out of the RZISBUFF and return to the PI domain caller in the supplied CHANBUFF which starts at 32700008. Somehow the data copied to the CHANBUFF is truncated. This leads to the severe error in DFHAPCR because the container header for the container following DFHWS-TEXTCONTENT is nulls.

Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: Message DFHAP0002 (code X'4E13') when * * DFHAPCR performs an IMPORT_ALL * * function. * **************************************************************** CICS is acting as a web service provider. The PIPELINE includes a handler program which causes a context switch to take place by changing the userid or tranid. The new task runs in the same CICS region, connected to the original task using request streams. The application code runs in the new task and creates a large amount of container data such that the total size of the channel is greater than x'8000000' (decimal 1342217728 ) bytes. On completion of the new task, DFHAPCR EXPORT_ALL flattens the channel and returns it to the original task using request streams. The original task uses DFHAPCR IMPORT_ALL to recreate the channel data. The buffer containing the flattened channel has been truncated. x'8000000' bytes of data are missing. When DFHAPCR tries to process the first flattened container after the truncation it fails to detect the container header. Message DFHAP0002 (code X'4E13) is issued and a system dump is taken. Additional Keywords: msgDFHAP0002 AP0002 DFHWS-USERID DFHWS-TRANSID DFHRZSO
Problem conclusion
CICS has been modified so that the flattened channel data is no longer truncated when being passed using request streams.
