     I've had success using Machine_type = 2 on Gateway2000, Northgate
     Compaq (486 and an LTE laptop) and a no-name 486 clone.  I've only
     had to use other types for an IBM PS/2 and another machine which
     was running the QEMM memory manager (Machine_type =J).

     It will be real tight.  I'm not sure how much RAM your compiler
     needs.  Just the RDBMS seems to live fine with ~4 Megs of
     RAM.  If you want to use tools (SQL*Forms, SQL*Plus, etc.)
     you'll need around 8 Megs to support them.

     To do this, either specify the DYNAMIC_MEMORY parameter in
     the CONFIG.ORA file to be about 4 Megs (DYNAMIC_MEMORY = 4096)
     or there is some command line parameter for SQLPME (the Oracle
     protected mode memory manager) which can limit the amount
     of extended memory SQLPME will grab when it loads.

    Since Windows can run in 4 megs of RAM, you should be OK.

      This question has been popping up quite a bit lately. I'll
      give the short answer here - contact me for more details.

      Oracle's memory manager (SQLPME) is incompatible with MS-Windows
      memory management.  When Windows is running in Enhanced mode,
      there is no way a Windows app can see the local Oracle RDBMS.

      You can, however, run Windows in Standard mode (WIN /S), 
      and, possibly in 4 Megs of RAM too.  WHen doing so, Windows
      apps can see the local RDBMS and talk to it.

      THe downside to running Windows in standard mode is that you 
      do not get access to virtual memory which means the 4 Megs
      of physical RAM you have (left over from loading SQLPME)
      is all you can work with.

       Don't know about the memory requirements for Visual C but I'd
      bet that it needs quite a bit of RAM to get anything
      significant going.  I struggled with MS C/C++ version 7 and
      gave up (I too only had 8 megs of RAM at the time).

>4. Is there a configuration that will allow me to run ORACLE in a DOS

      Definitely not.

        What I've been suggesting is getting OS/2 2.1, Oracle RDBMS
        for OS/2 and the SQL*VDM product which lets you run Windows
        apps in an OS/2 Windows session which can talk to the Oracle
        OS/2 RDBMS.  Mo' betta' IMHO.

Good luck
