Oracle is a complete database system. It has the ability to run in
protected mode on an 80286, 80386, or 80486 computer with the use of its
own protected-mode kernel. Oracle 5.1c runs correctly with HIMEM.SYS and
DOS=HIGH. However, if the EMM386.EXE privileged operation error occurs when
ORACLE.BAT is executed, Oracle may need to be reconfigured to run on a
Virtual Control Program Interface (VCPI) machine type.
There is an option in the Oracle setup program to specify the type of
computer on which Oracle is being installed. If Oracle 5.1c is being set up
for the first time and EMM386.EXE is being used, select VCPI as the machine
type. (EMM386.EXE is a VCPI host.) If Oracle is already installed, the
machine type can be changed by typing the command machtype
at the MS-DOS command prompt. This command runs the setup
program that allows you to change the machine-type option.
Oracle requires a minimum of 894 kilobytes expanded memory, so the DEVICE
line for EMM386.EXE in the CONFIG.SYS should read as follows:
device=c:\dos\emm386.exe ram 1024
If Oracle reports insufficient memory to run a specific task with the above
line in the CONFIG.SYS file, increase the amount of expanded memory that
