Error description
DFHSM0002 SEVERE ERROR CODE X'030E' HAS OCCURRED IN DFHSMGF found during normal processing. Code x'030E' means "quickcell freemain invalid QPH". QPH_SCAP is overlaid with binary zeroes. The 030E error code was issued due to an overlay of the QPH for subpool TSMDB at offset x'2C'. This is field QPH_SCAP, and should point back to the SCA, but instead contained zeros. CSXM was running to collect statistics. A dump from running with a DFHTRAP to get closer to the problem revealed that the overlay was occurring in module DFHFCST. Addtional symptom(s): KIXREVSCB

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: DFHSM0002 A severe error (code X'030E') * * has occurred in module DFHSMGF. * **************************************************************** * RECOMMENDATION: * **************************************************************** End-of-Day ( EOD ) statistics are being collected on a CICS region that uses BDAM files. Statistics are built and recorded from FCT fields associated to the file being processed and then the fields are reset to zero. One field, FCTDSDEL which only relates to VSAM files, is being reset against a BDAM FCT. BDAM and VSAM FCT's differ in size, BDAM FCT's are much smaller. The displacement of FCTDSDEL in VSAM's FCT extends beyond the limit of a BDAM FCT. If storage at this displacement (x'E4') has already been allocated for another purpose it will become corrupted. In this case, displacement x'E4' was populated with a QPH block pointer. As a result, when it was next referenced to perform freemain of quickcell storage message 'DFHSM0002 error code X'030E' from DFHSMGF' was issued. Additional Keywords: MSHDFHSM0002 SM0002 QPH_SCAP
Problem conclusion
DFHFCST has been changed so that after statistics have been collected, FCTDSDEL will only be reset for VSAM files.
