.H1;Installation
Multiple Server Support

In this release only, Macintosh netstations are not able to use
3+Route to access shared folders and printers on remote servers
via modem and telephone line connections.  3+Route can
continue to be used by IBM PC and compatible netstation users
in this manner and will continue to support sending and receiving
of messages via 3+Mail.  Full 3+Route support for Macintosh
netstation users will be included in a future release.

However, you can configure your network to support multiple
servers by connecting the servers with Ethernet.  Each server on
the network can have an Ethernet segment and an AppleTalk
segment attached to it.  Macintosh netstation users can then
access shared folders or shared printers on any server on the
network.

Disabling Printed Error Messages

If a printer error occurs when a document is printing, PostScript
printers attached to a 3+Share server will print an error message.
You can disable the printing of these messages by modifying the
3PLUS_ON.BAT file on the server.  Follow these steps to make
the modification.

.LT
1. Establish a 3Console connection to the server.
See Appendix A of the 3+ for Macintosh Supplement for
details on establishing a 3Console connection.

2. At the C>> prompt, enter
   3EDLIN \3CONFIG\3PLUS_ON.BAT
   and press [Return].

3. At the * prompt, enter 375 [Return].
   The screen displays the following:

   375:* 3share
   375:*

4. Enter 3Share /D=001 and press [Return].
The /D=001 parameter tells 3+ not to print error messages on
the printer.  If you change your mind later and want the
messages to be printed, follow these steps again, omitting the
/D=001 parameter.

5. Enter E and press [Return].
This saves the changes and exits the 3EDLIN program.

Supp 2-1 Installing with a Port Expansion Board

If your 3Server3 has a port expansion board installed, you must
connect the AppleTalk cabling to the AppleTalk port on the port
expansion board.  No jumper changes are necessary.

Supp 2-7 Installing with 3+ Version 1.2

If your server has 3+ version 1.2 installed, your PC netstations
are using NetBIOS, and you are adding 3+ for Macintosh, check
parameters for all services after installation.  Make sure the
Locator is installed on one and only one network server,
usually the Name server.  The network will not operate correctly
if the Locator is installed on more than one server.

Supp 2-7 Installing with 3+Route or 3+Remote

2-11 Installing 3+NetConnect alone without deleting 3+Route or
3+Remote will result in the message

Runminds Failure

on the server's LCD during startup.  If your server has 3+Route
or 3+Remote installed before adding 3+ for Macintosh, you
must do one of the following:

Deinstall 3+Route or 3+Remote.

Choose Install Individual Services from the 3INSTALL main
menu and install either NetConnect and Route or NetConnect
and Remote.

Supp 3-4 Printer Installation

I&C 5-60

If your server was previously installed with 3+ version 1.1
or
1.2 and had a printer configured, after installing one of the 3+
for Macintosh standard configuration sets, you must reconfigure
the printer.  To reconfigure, select "Configure Parameters and
Peripherals" from the 3INSTALL main menu.  See Chapter 5 of
the 3+ Installation and Configuration Guide for complete
instructions.

Supp 4-2 User Installation

3+ Startup diskettes can be used on any Macintosh netstation.
However, saved startup configurations will not work when using
the 3+ Startup diskette on a Macintosh netstation connected to an
AppleTalk segment on a different server.  To change the startup
configuration, choose the Chooser, log into the network, link to
the desired shared folders or printers, click Status in the 3+
Network Window, click Save as Startup, then click OK..  To
delete the startup configuration, open the System Folder and drag
the file 3+Prep to the trash can.

3+Share Parameter Adjustment

I&C 5-56

The default message buffer size for 3+Share for Macintosh is
2608.  For best results, we recommend you use this setting.  If
you configure a message buffer size larger than 4144, Macintosh
netstations can lose their connections to network servers.

I&C 5-57

The 3+Share for Macintosh packet receive buffers are set by
default to 8.  For best results, we recommend you use this
setting.  If you adjust the packet receive buffers, make sure they
are configured to a number less than the ETH3 -h parameter in
your CONFIG.SYS file.  For complete information on the ETH3
-h parameter, see Appendix D of the 3+ Installation and
Configuration Guide.


I&C 5-34

CIOSYS Parameter Adjustment

3+ for Macintosh requires the CIOSYS file descriptors and file
handlers to be set to a higher value than what is acceptable for PC
netstation configurations.  The defaults provided in the 3+ for
Macintosh standard configurations should be used for best
results.

Supp B-1

Macintosh Service Parameter
Adjustment

I&C 5-36 The number of Macintosh threads must be less than or equal to
the number of CIOSYS threads.  If Macintosh threads are set to a
higher number than CIOSYS threads, the setting for CIOSYS
threads is used.  If you want to increase the Macintosh threads,
first change the CIOSYS threads parameter, select Keep to save
the changes, then adjust the Macintosh service threads.

Manual Errata

Supp 3-8 The default for number of buffers used by 3+NetConnect  is 8.

.LT
Supp 3-11 The following mappings have been added to the default
B-6 Extension Mapping Table:
B-8
DOC=MSWD,WDBN Microsoft Word Version 3.0 file
STY=MSWD,TEXT Microsoft Word Version 3.0 style
sheet
GLY=MSWD,TEXT Microsoft Word Version 3.0 global
style sheet
TIF=ALD2,TIFF Pagemaker Version 2.0 TIFF format
picture file
.EL

Additionally, the last extension mapping shown in Tables B-2
and B-3 should read as follows:

   <Any other extension>=3MAC,TEXT



.H1;Administration

Guide Page

3+ Backup

Use of 3+Backup on shared folders containing Macintosh files
should only be done from a DOS directory level or higher.
Because 3+Backup is not aware of Macintosh file characteristics,
always restore into empty directories and merge the results.  If
you use 3+Backup to restore over a directory that contains
Macintosh files (or DOS files that have acquired Macintosh file
characteristics), you will lose Macintosh files that existed in the
directory prior to the restore.  If applications are restored, the
Finder may not be able to locate them when opening a document
unless you rebuild the desktop by pressing
[Command]+[Option] when returning to the Finder.  If you
have nested shared folders, always rebuild the desktop from the
from the Home Folder level or another first-level shared directory
(such as 3PLUS or APPS).

The tape backup unit and AppleTalk share the same circuitry.
Therefore, tape backups should be performed during times of
low network activity.  Macintosh netstations can access the
server during backup, but only when there is no tape activity.
Because periods of tape activity can be several minutes long,
links to shared folders can be lost.

General Issues

Occcasionally an application may generate a system error without
breaking links to shared folders.  The server will try to
reestablish a link to the shared folder or folders for approximately
two minutes.  After that time, restarting and logging into the
network from the same netstation should allow you to link to the
shared folder again.  If an error message is displayed when
trying to link to a shared folder after logging into the network
from the same netstation, log in as Admin and unlink the user
from within the 3+Admin application.  See "Unlinking a User" in
Chapter 2 of the 3+ for Macintosh Administrator's Guide  for
information on doing unlink a user.

Admin 3-8 If the 3+ Network Window is blank when you open 3+Admin,
quit the application, choose the Control Panel from the Apple
menu, lower the amount of RAM Cache or turn RAM Cache off,
and try again.  This provides more memory to be available for 3+
Admin.

Admin 2-11 Sharing a Folder as Server-User

By logging into the network as a server-user, you can create and
share folders in one step.  These shared folders can be accessed
by all network users by selecting the server's name in the 3+
Network Window and clicking Open.  Because they are easy to
find, server-user shared folders are useful for storing multiuser
network applications or files needed by multiple network users.

1. Log in as the server-user for the server on which
you want to create and share a folder.
If you do not known how to do this, see "Logging In as a
Server-User" in Chapter 4 of the 3+ for Macintosh
Administrator's Guide.

2. In the 3+ Network Window, click Share.
When you first log in as a server-user, Share is enabled.
This allows you to create a folder and share it at the same
time.  The following screen is displayed.

3. Enter a shared folder name for the folder.
The shared folder name can be from 1 to 8 characters long
with no spaces.  Use a name that is descriptive of the folder's
contents.  For example, if the folder will contain applications,
enter a shared folder name of APPS.

4. Enter a password in the Password box, if desired.
A password is not required, however if the shared folder is
assigned Private access rights and no password, it will be
inaccessible.

5. Enter the DOS path for the folder you are sharing
in the Path box.
For example, to create and share a new directory for multiuser
network applications, specify the path C:\APPS.

The DOS path specifies the folder name and the exact location
on the server's disk where the new folder will reside.  The
DOS path always begins with the drive designation where the
folder will reside.

Your server's hard disk is divided into three sections, or
partitions, that are assigned the drive designations C:, D:, and
E:.  Each folder you create from a Macintosh netstation is
represented by a DOS directory on the server's disk.  In
addition to the directories representing your folders, 3+
creates directories on the server's drive C: that are used to
organize the system files.  You can see what partitions and
how much space is available on each by selecting the server's
name in the 3+ Network Window and clicking Getinfo.

The DOS directory structure is hierarchical the same way
Macintosh folders are hierarchical.  The figure below
illustrates the DOS directory structure on drive C: of a server.

3+ Server Directory Structure

In a DOS path, the drive designator and levels of the directory
(or folder) hierarchy are separated by a backslash (\).  Each
level of the hierarchy is assigned a name from 1 to 8
characters long with no spaces.  Using this method, the path
to the directory 3PLUS, shown in the figure above, is
C:\3PLUS.  The path to the directory 3NAME is
C:\3PLUS\3NAME.

As server-user, you can share any directory on the server's
hard disk except the root directory (C:\) and create and share
new directories.

6. Select the appropriate Access Rights for the new
shared folder. Most shared folders created by the server-user contain
shared applications and files.  Read Only access rights are usually
appropriate for folders containing shared applications.  The
default access rights are Read/Write/Create and are usually
appropriate for folders containing shared files or applications
that modify themselves.  When using a multiuser network
application, refer to that application's documentation for more
information on the access rights you should assign to folders
containing the application's data files.

If you assign Private access rights, you must assign a
password.  Folders assigned Private access rights and no
password are not accessible, even by the server-user.

7. Click OK to create the folder and shared folder
name.  The 3+ Network Window is displayed on the screen and the
new shared folder appears in the list box.  Click Cancel to
bypass creating and sharing the folder.

Admin 3-22 Modifying a User

Modifying your capability class from Admin to User or changing
the name of your Mail or Share server does not take effect until
you log out.  Prior to logging out, you will continue to have
access to Admin functions.

Admin 3-27 Deleting a Domain

Deleting the last domain in an organization causes the
organization to be deleted in the Name service.  However, the
organization remains as the title of the list box in the 3+ Network
Window.  Changing the title of the list box to Network removes
the organization from the 3+ Network Window display.

Admin 3-9 Adding Users

When adding users on your 3+ for Macintosh server, it is not
necessary to create a new domain with its own network number.
3+ for Macintosh uses the same Name service as the PC
netstations on your network.

Error Messages

Admin A-7 The message

Internal driver error.  Error 5, Type -95

indicates a problem has occurred when trying to save a startup
configuration in the 3+ Network Window.  A more explicit error
message is displayed before this one.  No action is required.
Simply click OK and continue working.  Try saving the startup
configuration again later.

Admin A-11 The message

Name server not responding.

indicates that the Name server is either shut down, disconnected
from the network, or busy with requests and unable to respond
to your netstation's request.  Make sure the Name server is in
operation, connected to the network, and no break exists in the
network cabling.  If the message occurs frequently, move one or
more 3+ services to a different server.  If you are using a PC
server as the network's Name server and this message occurs
frequently, move the Name service to a 3Server.

Admin A-15 The message

"server:domain:organization" is not responding.  Retrying...
indicates the server is not responding to requests.  3+ will
continue trying to establish communication with the server unless
you cancel by pressing [Command]+[.].  Cancelling the
operation breaks all connections to the indicated 3+Share server.
Reboot your Macintosh and log in before continuing work.



Admin A-19 The message

The print queue is full.

indicates the maximum number of print queue entries has been
reached.  Click 3+Print in the Chooser and look at the print
queue.  When one or more print jobs leaves the queue, print the
document again.  If the message appears frequently, increase the
maximum print queue entries allowed in the 3+Share Pring
service by using the 3INSTALL program.  See Chapter 5 of the
3+ Installation and Configuration Guide for instructions.

Admin A-19 The message

The print server's disk is out of space.
indicates drive C: on the 3+Share server to which the printer is
attached is full.  Make space available on the drive by removing
unnecessary files in one or more user's Home Folders, or move
one or more user's Home Folders to a different partition or
server on, if you have not already.
