    ****************************************************************
    For applications that rely on real-time statistics (RTS)
    the asynchronous externalization process of RTS might be too
    imprecise. For these kind of applications a callable interface
    that can trigger the externalization of pending RTS changes
    is needed.
    

Problem conclusion

Temporary fix

Comments

  • This APAR adds a new MODE option to the ACCESS DATABASE
    command. The new option "STATS" can be used to externalize
    pending real-time statistics.

    New option description:
    
    MODE( mode-value )
    
      STATS:
      Externalizes the in-memory real-time statistics to the
      appropriate catalog tables. In data sharing environments,
      the in-memory statistics are externalized for all members.
      This mode does not physically open the page sets or change
      the states of the page sets.
