APAR status

• Closed as new function.

Error description

  * RECOMMENDATION: APPLY PTF.                                   *
  ****************************************************************
  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.
