<h1>MOSS Memory Management Simulator
|
|
|
|
<br>Installation on Windows 95/98/Me/NT/2000 Systems</h1>
|
|

|
|
|
|
|
<h2>Purpose</h2>
|
|
|
|
<p>
|
|
This document provides instructions for the installation
|
|
of the MOSS Memory Management Simulator on
|
|
|
|
Microsoft Windows
|
|
|
|
|
|
operating systems. This procedure should be the same or similar on
|
|
|
|
Windows 95, 98, Me, NT, and 2000
|
|
|
|
|
|
systems.
|
|
The MOSS software
|
|
is designed for use with
|
|
<a href="http://www.cs.vu.nl/~ast/">Andrew S. Tanenbaum</a>,
|
|
<a href="http://vig.prenhall.com/catalog/academic/product/1,4096,0130313580,00.html">Modern Operating Systems, 2nd Edition</a>
|
|
(<a href="http://www.prenhall.com/">Prentice Hall</a>, 2001).
|
|
The Memory Management Simulator was written by

|
|
<h2>Requirements</h2>
|
|
|
|
The following software components are required
|
|
to install and use the MOSS Memory Management
|
|
Simulator.
|
|
<ul>
|
|
|
|
<li>Microsoft Windows 95, 98, Me, NT, or 2000
|
|
|
|
|
|
<li>Java Development Kit (JDK) 1.0 or greater
|
|
<li>Text program editor (e.g., notepad)
|
|
</ul>
|
|
|
|
<h2>Pre-Installation</h2>
|
|
<p>
|
|
Before installation, you should verify:
|
|
</p>
|
|
<ul>
|
|
<li>that you have a working java runtime environment,
|
|
<li>that you have a working java development environment, and
|
|
<li>that the working directory is in the classpath for the runtime environment.
|
|
</ul>
|
|
<p>
|
|
If you're using a standard command-line java compiler, the following
|
|
instructions will help determine if your environment is configured
|
|
correctly.
|
|
</p>
|
|
<ol>
|
|
<li>Verify that you have java installed and configured in your environment.
|
|
|
|
<blockquote><pre>
|
|
C:\WINDOWS> java -version
|
|
</pre></blockquote>
|
|
|
|
|
|
You should see a message like this with possibly a different version number.
|
|
<blockquote><pre>
|
|
java version "1.1.8"
|
|
</pre></blockquote>
|
|
If you get a message like:
|
|
|
|
<blockquote><pre>
|
|
Bad command or file name
|
|
</pre></blockquote>
|
|
|
|
|
|
Then java may not be installed on your system, or may not be configured
|
|
for your use.
|
|
<p>
|
|
If you think that Java may already be installed on your system
|
|
but may not be in your "path", you can find it by
|
|
|
|
choosing Start -> Find -> Files or Folders
|
|
and enter "java.exe" in the "Named:" field and click the Find Now button.
|
|
If found, make note of the directory folder in which it resides (e.g.,
|
|
"C:\jdk1.1.8\bin").
|
|
<p>
|
|
While you're at it, also seach for javac.exe to see if the Java
|
|
compiler is installed and whether it's in the same directory as
|
|
the java.exe file.
|
|
|
|
|
|
<p>
|
|
If Java isn't available on your system, you should check with
|
|
your instructor or system administrator. If you administer your
|
|
own system, then you should be able to find a copy of Java
|
|
for your operating system.
|
|
<p>
|
|
If you find that java is installed but not configured for
|
|
your use, then perhaps you need to add it to your path. Consult
|
|
your instructor or system administrator if you need help adding this
|
|
to your path.
|
|
</p>
|
|
<p><!-- --></p>
|
|
|
|
<li>Verify that the java compiler is installed and configured in
|
|
your environment.
|
|
|
|
<blockquote><pre>
|
|
C:\WINDOWS> javac
|
|
</pre></blockquote>
|
|
|
|
|
|
If you're using a standard java command-line compiler, you should
|
|
see a message similar to this.
|
|
<blockquote><pre>
|
|
use: javac [-g][-O][-debug][-depend][-nowarn][-verbose][-classpath path][-nowrite][-deprecation][-d dir][-J<runtime flag>] file.java...
|
|
</pre></blockquote>
|
|
If you get a message like:
|
|
|
|
<blockquote><pre>
|
|
Bad command or file name
|
|
</pre></blockquote>
|
|
|
|
|
|
then the java compiler may not be installed on your system, or
|
|
may not be configured for your use. Consult your instructor
|
|
or system administrator.
|
|
<p><!-- --></p>
|
|
|
|
<li>Verify that that the current directory is in your classpath.
|
|
|
|
<blockquote><pre>
|
|
C:\WINDOWS> echo "%CLASSPATH%"
|
|
</pre></blockquote>
|
|
You should see a list of directories separated by semi-colons (";")
|
|
or possibly just "". If you don't see the directory "." (a single
|
|
period, which stands for the current directory), then you should
|
|
add it to the classpath.
|
|
<blockquote><pre>
|
|
C:\WINDOWS> set CLASSPATH=.;%CLASSPATH%
|
|
</pre></blockquote>
|
|
|
|
|
|
<p><!-- --></p>
|
|
|
|
</ol>
|
|
<p>
|
|
If you have a working java runtime environment, a working java
|
|
compiler, and the current directory is in your path, then you're
|
|
ready to proceed with the installation.
|
|
</p>
|
|
|
|
|
|
<h2>Installation</h2>
|
|
|
|
Installation of the software can be accomplished with
|
|
these simple steps:
|
|
<ol>
|
|
<li>
|
|
|
|
Create a directory folder in which you wish to install
|
|
the simulator (e.g., "C:\moss\memory"). You can do
|
|
this using the Windows explorer, or from the MS-DOS
|
|
prompt. To create the directory from the MS-DOS
|
|
prompt:
|
|
<blockquote><pre>
|
|
C:\WINDOWS> cd \
|
|
C:\> mkdir moss
|
|
C:\> cd moss
|
|
C:\moss> mkdir memory
|
|
C:\moss> cd memory
|
|
C:\moss\memory>
|
|
</pre></blockquote>
|
|
|
|
|
|
<p><!-- --></p>
|
|
|
|
<li>
|
|
|
|
Download the self-extracting ZIP archive (memory.exe) into
|
|
the directory folder.
|
|
The latest release for this file can always be found at
|
|
<a href="http://www.ontko.com/moss/memory/memory.exe">http://www.ontko.com/moss/memory/memory.exe</a>.
|
|
|
|
|
|
<p><!-- --></p>
|
|
|
|
<li>
|
|
|
|
Double-click on the file you downloaded (memory.exe),
|
|
or invoke it using Start -> Run..., or invoke it
|
|
from an MS-DOS command prompt:
|
|
<blockquote><pre>
|
|
C:\moss\memory> memory.exe
|
|
</pre></blockquote>
|
|
|
|
|
|
<p><!-- --></p>
|
|
|
|
</ol>
|
|
|
|
<h2>Files</h2>
|
|
<p>
|
|
The directory should now contain the following files:
|
|

<h2>Compilation</h2>
|
|
|
|
<p>
|
|
The distribution includes compiled class files as
|
|
well as the source java files. You should not need
|
|
to recompile unless you decide to change the code.
|
|
If you wish to compile the code,
|
|
the following commands should work if you're using
|
|
a Java compiler that accepts the normal "javac" command
|
|
line.
|
|
|
|
<blockquote><pre>
|
|
C:\moss\memory> javac -nowarn *.java
|
|
</pre></blockquote>
|
|
|
|
|
|
|
|
The <tt>-nowarn</tt> flag supresses warning messges, of which
|
|
there may be several. For backward compatability we use only
|
|
those features of Java which have been present from the beginning,
|
|
some of which are deprecated and are usually reported by the
|
|
compiler with warning messages.
|
|
|
|
<h2>Test</h2>
|
|
|
|
<p>
|
|
To test the program, enter the following command line.
|
|
|
|
|
|
<blockquote><pre>
|
|
C:\moss\memory> java MemoryManagement commands memory.conf
|
|
</pre></blockquote>
|
|
|
|
|
|
|
|
<p>
|
|
The program will display a window allowing you to run the
|
|
simulator.
|
|
When the window presents itself, click on the Run
|
|
button.
|
|
You should see the
|
|
program "execute" 7 memory operations, about one per second.
|
|
When the simulation completes, click the
|
|
Exit button.
|
|
<p>
|
|
The memory operation commands are read from a file called
|
|
"commands",
|
|
and the initial configuration and various options are
|
|
specified in the file "memory.conf".
|
|
The program also produces a log file called "tracefile"
|
|
in the working directory.
|
|
|
|
<p>
|
|
The "commands" file looks something like this:
|
|
<blockquote><pre>
|
|
// Enter READ/WRITE commands into this file
|
|
// READ <OPTIONAL number type: bin/hex/oct> <virtual memory address or random>
|
|
// WRITE <OPTIONAL number type: bin/hex/oct> <virtual memory address or random>
|
|
READ bin 100
|
|
READ 19
|
|
WRITE hex CC32
|
|
READ bin 10000000000000000
|
|
READ bin 10000000000000000
|
|
WRITE bin 11000000000000001
|
|
WRITE random
|
|
</pre></blockquote>
|
|
|
|
<p>
|
|
If things are working correctly, the "tracefile" should look
|
|
something like this:
|
|
|
|
<blockquote><pre>
|
|
READ 4 ... okay
|
|
READ 13 ... okay
|
|
WRITE 3acc32 ... okay
|
|
READ 10000000 ... okay
|
|
READ 10000000 ... okay
|
|
WRITE c0001000 ... page fault
|
|
WRITE 1ff82cdc ... okay
|
|
</pre></blockquote>
|
|
|
|
