ABOUT THE APPLE WORKGROUP SERVER 95 TUNE-UP

The Apple Workgroup Server 95 Tune-Up is a set of enhancements to the A/UX
operating system and AppleShare Pro. The tune-up software includes the System 7
Tune-Up, which upgrades the Macintosh system software running in the A/UX
environment. (The System 7 Tune-Up file is called "System 7 Tuner.")

Together, these enhancements improve the performance of your server in a number
of ways:
• File-management features work more smoothly, resulting in fewer problems with
  time-stamping, name changes to files and folders, and file locking.
• Error handling and recovery are improved.
• Security is more effective; for example, the system checks UNIX® permissions
  of target files with symbolic links.
• Hardware support is enhanced, including improved support for the AppleCD 300
  CD-ROM Drive, on-board video, and the Apple Hard Disk 230SC.

To get the maximum performance and minimize problems with your server, it is
important to install the Apple Workgroup Server 95 Tune-Up. This update tells
you how to install the tune-up software, lists the files affected by the
changes to the server software, describes in more detail the improvements
provided by the tune-up, and lists changes of interest to developers.


TUNE-UP INSTALLATION PROCEDURE

The tune-up Installer automatically installs the software that you need to take
advantage of the enhancements. On all configurations of the AWS 95, it also
automatically installs the System 7 Tune-Up.

The Apple Workgroup Server 95 Tune-Up updates the A/UX operating system from
version 3.0.1 to 3.0.2, and updates AppleShare Pro (if present on your server)
from 1.0 to 1.0.1. The installation process doesn't affect any of the current
kernel parameter settings.

If AppleShare Pro is NOT installed on your server, you will only need Disk1.

Before You Begin

Before you begin the installation, be sure to back up all files and notify
users that you will be shutting down the server in order to install the tune-up
software. During the installation process, the system quits all programs
running on the server; you must restart the server to complete the
installation.

To perform the installation, you must be logged in to the server as "root". If
your server is set up with the default configuration for file and print
services, and the Autologin feature is enabled, you should be logged in as
"root" automatically when you start the server. If your server is configured as
a database server, you must log in as "root" by means of the Login dialog box.


Installing the Tune-Up Software

Make sure that you are logged in as "root" and then follow these steps:

1. Insert the disk labeled "AppleShare Workgroup Server 95 Tune-Up Disk 1."

If the CommandShell application is the active application, the system displays
this message: "This is a Macintosh disk. What do you want to use it as?" If
this message appears, click the button labeled "Macintosh."

2. Double-click the Installer icon.

This message appears: "You can only install the AWS 95 Tune-Up on the root
volume, '/.' Please click Switch Disk to choose this disk."

3. Click Switch Disk until '/' is selected.

4. Click the Install button.

5. Click Continue to automatically quit all other running applications.

The tune-up installation begins, and the system displays a progress bar and
status messages during the process.

6. If AppleShare Pro is installed on your server, the system prompts you to
insert Disk 2, then to re-insert Disk 1.

The kernel is reconfigured; this process may take several minutes. After your
server has loaded all of the appropriate tune-up software, the message
"Installation successful" appears.

7. Click the Restart button to complete the installation.

NOTE: If you routinely back up the server's system files (for example, to
tape), you should make a new backup after performing the installation, as the
system files will have been upgraded.


Re-Installing Appleshare Pro

If you use version 1.0 of the AppleShare Installer to re-install AppleShare Pro
after installing the tune-up, your server displays the message "You must be
running A/UX version 3.0.1 when performing this installation." To perform the
AppleShare Pro installation, click the Customize button, select all the items
listed in the Customize dialog box, then click Install (not Easy Install). Then
re-install the tune-up in order to update your system with the latest version
of AppleShare Pro.

For details on installing AppleShare Pro, see "AppleShare Pro Administrator's
Guide."

catsearchd
disktab
fidd
fsck
newfs
newunix
Patch.067C
rcp

• AppleShare files:

AppleShare Pro Admin
AppleShare Pro File Server
File Server Extension


CHANGES AND ENHANCEMENTS

The tune-up software differs from the software originally shipped with the AWS
95 in the following ways.

A/UX Changes

• The tune-up installs A/UX version 3.0.2 on the system.

• The system maintains the modification date and time on folders and files
  correctly.

• You can change the case of a Macintosh filename--for example, from "filename"
  to "FILENAME".

• The tune-up provides improved security when the utilities "rcp", "rdist", and
  "tip" are used.

• Files and folders that are unlocked remain unlocked unless a user
  deliberately locks them.

• The system maintains the modification date for files manipulated by means of
  Adobe Illustrator 3.2.

• Users who do not have "root" privileges can no longer gain write access to
  files pointed to by symbolic links, UNLESS the UNIX permissions on the target
  file grant write access to the entire world.

• Symbolic links to a directory are also intercepted if the target directory
  does not have read/write permission for the world.  As a side effect, in this
  case, users will not be able to remove the symbolic link by dragging it to
  the trash.

• If the Desktop database becomes corrupted because of a crash, it will
  automatically be rebuilt the next time the system is started.

• The Alias Manager correctly resolves the pathname for files or folders that
  are created on the desktop.

• Read and Write commands are issued asynchronously for files opened by means
  of the extended FCB mechanism, which is used by AppleShare to support more
  than 348 concurrently open files.  As a result, server performance is
  improved.

• The file Autologin.4.Z provides the correct manual ("man") page for
  Autologin, replacing the page shipped with A/UX 3.0.1. This file is updated
  only if the UNIX manual pages are installed on the system.

• File IDs are persistent across a system crash.  The file ID daemon ("fidd")
  now flushes its database (which contains the file-ID-to-UNIX-pathname
  mappings) to the disk within 30 seconds of the addition of a new entry.

• Date searches around Jan 1, 1977 are performed correctly.  Dates are now
  stored as signed longs.

• A problem with accessing the system parameter RAM, which could cause on-board
  video to be nonfunctional at system startup, has been corrected.

• The driver for the AppleCD 300 CD-ROM Drive provides improved support for all
  versions of the drive-unit ROMs. However, it is recommended that old ROMs be
  upgraded, since they can cause the SCSI bus to hang. The system will notify
  you if it encounters an old AppleCD 300 drive-unit ROM.

• The size of each internal system cache has been increased to improve system
  performance.

• Users can start up the system whether or not a keyboard or mouse is attached.

• Drive entries for the Apple Hard Disk 230SC and the Hard Disk 400SC have been
  added to the "disktab" database.


AppleShare Pro Changes

• The tune-up installs version 1.0.1 of AppleShare Pro on the system.

• The amount of free space available on a disk is now returned correctly to the
  AppleShare client.

• The write algorithm for the AppleShare Pro Server has been fixed so that it
  no longer schedules a write operation as a deferred task to a deferred task.
  As a result, server performance is improved.

• Users can perform searches of the Desktop database without risk of running
  out of stack space and crashing the system.

• The number of shareable items is no longer limited.

• PC clients get a correct directory listing when the user types the "dir"
  command.

• Files can be read nonsequentially without risk of the return of an erroneous
  EOF.

• The "Copy to" function of AppleShare Pro Admin uses the mount point that was
  the intended target.  (In the original version, the free space available on
  the "/" partition was sometimes, incorrectly, used instead.)


   CHANGES OF INTEREST TO DEVELOPERS

• The PPCWrite function (or trap) no longer sends out duplicate ADSP packets.

• The "exchangeFiles" trap correctly preserves the fork lengths in all cases
  (UNIX file system only).

• The Time Manager returns accurately the unexpired time for a "RmvTime" trap.
  As a result, write performance to servers on busy networks is improved.

• The "Rename" trap functions correctly when subpaths containing folders are
  specified (that is, when the pathname is not absolute or just a simple
  filename).

• The PBHDelete function (or trap) performs correctly even if no file or folder
  name is specified (that is, if only a dirID is set in the parameter block).

• The ADSP driver on the server correctly reports an error condition if a
  client crashes.

• The performance of "catsearch" by dirID (that is, return all files and
  folders whose parent dirID matches the specified dirID) has been improved by
  at least a factor of 2.

• The  handling of "eofErr" at the end of a search performed by a call to
  "catsearch" has been corrected.  When the "eofErr" is encountered, the system
  returns the last block of matches.
