APAR status

  • Closed as program error.

Error description

  • You have PDQPRIORITY set to 1 or higher. You have STMT_CACHE
    enabled. You run this select
    statement multiple times:
    
    select * from sysdri ( in sysmaster )
    
    Data is returned for the first several runs depending on the
    STMT_CACHE_HITS setting but subsequent runs
    return no rows. If you restart the database server then the
    behavior is reset.
    
    You run one or both of these multiple times:
    
    onpload job
    onpladm job
    
    The jobs run successfully for the first several runs but
    subsequent runs return errors like these:
    
    Error accessing table 'sysdri', SQL error 100, ISAM error 0
    
    Error occured at HPL failpoint: 11431
    
    Error occured at HPL failpoint: 11008
    

Local fix

  • Restart the database server.
    Do not run any of these with PDQPRIORITY enabled:
    onpload
    onpladm
    select * from sysdri
