ECO KIT SUMMARY:

An ECO kit exists for Reliable Transaction Router on DIGITAL UNIX
V3.2 through V4.0D.  This kit addresses the following problems: 

Problems Addressed in RTR31D173:

  o  A problem introduced in the 3.1D ECO1 (170) release that caused 
     errors when using more than one partition has been corrected.

     The following restrictions apply to this kit:

     o   The values for partition bounds are (as in previous
         versions) returned as binary values.  A future version of 
         RTR V3 will return these values as textual data.

     o   An application's wakeup routine may be called more often
        than necessary.


Problems Addressed in RTR31D_170:

  o  A configuration including front end nodes running RTR V2 and
     router nodes running RTR V3.1D could result in an ACP failure with an
     assertion on the router node. This has been corrected.

  o  The RTR ACP process would sometimes crash due to mis-handling
     of data pointers related to key range and facility information.  The
     code has been changed to correct these problems.

  o  The delivery of the RTR_EVTNUM_SRPRIMARY event sometimes
     arrived at an application in Shadow Secondary mode before the
     completion of the pending transaction, which potentially allowed the
     same transaction to be played to both shadow sites.  This problem has
     been corrected by ensuring that the event is delivered only between
     transactions.

  o  Following facility reconfiguration with the "trim
     facility" command,  a situation could arise where a frontend node would
     be unable to connect to its own role as a router in a facility.  Once
     in this mode, starting client channels would be unable to proceed past
     the state "wait_keyin".

  o  The RTR Command Server process would sometimes crash while
     exiting because the shared memory segment required to print log file
     information was no longer available when the final flush of the log
     buffer occurred.  This problem has been corrected.
 

INSTALLATION NOTES:

The Reliable Transaction Router Version 3.1D ECO2 installation
procedure is the same as the installation procedure for RTR Version 3.1D.
