APAR status

  • Closed as program error.

Error description

  • If a runstats is invoked against a user temporary table and the
    index clause explicitly specifies index names but omits the
    index schema name, i.e. index name is not fully-qualified, the
    instance crashes with a signal 11.
    
    db2diag.log entry indicates that a db2sysc process is brought
    down with a signal 11 (0x0B)
    
    e.g.
    
    2014-06-27-03.24.55.682213-240 E492764A469          LEVEL: Error
    PID     : 7930224              TID : 258            PROC :
    db2wdog 3 [db2inst1]
    INSTANCE: db2inst1               NODE : 003
    HOSTNAME: hostname
    EDUID   : 258                  EDUNAME: db2wdog 3 [db2inst1]

    The stack becomes corrupted, and no FODC_Trap is generated. A
    core dump is generated, and db2sysc trapped in function strncpy
    (called by sqlrLocalRunstats).
    
    This problem exists only in v10.1; v9.7 and previous releases
    require fully-qualified index names in the index clause of the
    runstats command.
    

Local fix

  • Modify the runstats command to use fully-qualified index names.
