SUNDM

   - The updates as described in the release notes for PL/B in the section
     named 'PLBWIN, PLBNET, PLBSERVE, PLB(UNIX)' have been implemented for the
     Data Manager.
     
   - This release of the Data Manager only accesses/connects to the embedded
     SQLite database engine when a PLB program requires such access. Prior to
     this change a logon connection to the SQLite database engine was occurring
     when a PLB client logged on to the Data Manager. This was causing
     unnecessary memory allocations and accumulations to occur even though a
     program never used the SQLite functionality. Now, with the changes in the
     9.4A patch release, the embedded SQLite database engine is not accessed
     until a PLB program executes some instruction requiring it to be accessed.
     The overall changes for 9.4A correct an accumulation problem that would
     cause memory allocations to continually increase for the main Sundm
     process even after the client child threads were terminated.
