Error description
ABEND04E RC00C200C9 DSNB1OFA after changing zparm STATFDBKSCOPE from 'NONE' to 'ALL'. An internal halfword counter overflowed causing a large overlay. An internal DB2 PBG control block was overlayed resulting in subsystem termination. Changing STATFDBK_SCOPE back to 'NONE' circumvents the error. ADDITIONAL SYMPTOMS: ABEND0C4 DSNICMT2 RC00D93001 ABEND0C4 DSNB1PCK ABEND04E RC00C200D8
