APAR status

  • Closed as program error.

Error description

  • A program doing a PUT CONTAINER to more than 15Mb bytes
followed immediately by a GET CONTAINER of the same data.  The
length of data returned is correct but the actual data has been
truncated.

 The problem lies in DFHPGCR and seems to have been caused by
the introduction of PUT64 CONTAINER for 64-bit assembler
applications.  The previous code (4.2 and below) that handled
moving data into the container is no longer present.  A new 64
bit routine is being used now.  A routine has a single MVCL
leading to this data truncation.

Problem summary

  • ****************************************************************
* USERS AFFECTED: All CICS users                               *
****************************************************************
* PROBLEM DESCRIPTION: Container data is truncated while CICS  *
*                      does PUT CONTAINER with large data.     *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A container is used to pass large data(over 16M in size) from
one program to another. When a program does PUT CONTAINER,
DFHPGCR is called to copy the data to container. As one MVCL
is used to move this data, container data ends up being
truncated. Then another program does GET CONTAINER, the data
returned is truncated.

Problem conclusion

  • DFHPGCR has been changed to handle container data more than
16M.
