Solaris Easy Access Server 3.0 Installation Guide

Chapter 2 Preparing Your SEAS Installation

This chapter describes the system requirements, and how to prepare for installing the Solaris Easy Access Server 3.0 (SEAS) products.

Hardware and Software Requirements

The following lists the system requirements necessary for you to install SEAS and the SEAS clients.

A CD-ROM drive attached to the system where you plan to install the SEAS products.
The system on which you install the SEAS products must run the Solaris 2.6 or Solaris 7 operating environment. Many of the products also run on earlier versions of the Solaris environment (as mentioned in their online product documentation) but this capability is not supported as part of SEAS.
PCs running Windows 95, Windows 98, or Windows NT for installing SEAS client software.

Table 2-1 System Requirements of SEAS 3.0


SEAS 3.0 Product	Default Installation Path	Requirements
AdminSuite 3.0	`/opt`	7.0 MB diskspace.
DiskSuite 4.2	`/usr/opt`	20.6 MB disk space and at least two drives. If DiskSuite is already installed, see the section on Upgrading DiskSuite in this chapter.
PC NetLink 1.1	`/opt`	78.0 MB disk space. PC NetLink 1.1 is only supported on Solaris 2.6 and 2.7 on the SPARC and only 2.7 on Intel platforms.Ensure that no other program that uses a NetBIOS stack is running on the Solaris-based computer on which you will install PC NetLink. You will, however, have no problem with the NetWare or Apple functionality in TotalNET.
PC NetLink 1.1	`/var/opt`	Minimum: 15 MB disk space. Recommended: 100 MB.
Sun Enterprise Authentication Mechanism 1.0	`/`The default location for the KDC database is `/var`	3 MB in `/`16 MB in `/usr`144 KB in `/etc`.You must allow a minimum of 50 MB in B in `/var` for the KDC database on all KDC servers.
Netscape Communicator 4.5	`/opt`	21.5 MB. For each additional local language: 10 MB. Documentation: 300 KB
Solstice PPP 3.0.1	`/opt`	1.4MB disk space. An X Windows manager to provide a graphical user interface. There is also a command-line version of this utility.
Solstice Internet Mail Server 2.0	`/opt`	1.7 MB disk space. A fully installed and configured Sendmail program.
Solaris Print Manager 1.0	`/usr/sadm`	2.6 MB disk space.
Sun Directory Services 3.2	`/opt` The default location for the directory database is `/var`.	24.9 MB disk space in `/opt`, 2.0 MB in `/var` ,and 0.4 MB in `/etc`. You must allow enough disk space for the database. 1,000 entries require approximately 1.5 MB of disk space, 64 MB of RAM and 128 MB of swap. A Java-compatible browser. Recommended: HotJava 1.0.2.
Sun WebServer 2.1	`/usr`	Software: 11.3 MB and 2.0 MB disk space for documents and log files. Memory: 64 MB minimum, 96 MB is recommended. Requires JDK 1.1.6 or compatible version.
Solaris Management Console 1.0 (includes configuration wizards)	`/usr/sadm`	8.6 MB disk space.
J.D.K. 1.1.7	`/usr`	31.5 MB
WBEM/CIM SDK 1.0	`/opt/SUNWconn`	28.6 MB

Increasing Disk Space

Although the Web Start Wizard^TM checks the available disk space based on your installation selections, make sure you have sufficient disk space available before installing the SEAS products. Use Table 2-2 to determine your disk space needs. Note that disk space and memory requirements are approximate and may vary.

Table 2-2 Disk Space Requirements by Directory


Directory	Total Required Disk Space (in megabytes)
`/`	3
`/usr/opt`	20.6
`/opt`	130.3
`/opt/SUNWconn`	28.6
`/usr/adm`	2.6
`/usr/sadm`	8.6
`/usr`	60.8
`/etc`	0.6
`/var`	52.0 + 1.5 per 1,000 directory entries
`/var/opt`	15
Minimum Total disk space	323.6

Determining Current Disk Space Usage

When you suspect not having sufficient disk space in the directories in which SEAS product files are installed, you may find the following commands useful in determining the current disk space usage.

The Display Filesystem Statistics command: df -k

The Report on Disk Usage command: du directory

Display Filesystem Statistics: `df -k` `directory`

The command df -k directory displays the used and available disk space for each of the mounted file systems. The example indicates that 101061 kilobytes are available in /opt

For example: df -k /opt could display something like the following:

Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0t0d0s5     123455   10049  101061    10%    /opt

Report on Disk Usage: `du` `directory`

The command du directory reports the amount of disk space used by all files and subdirectories underneath one of more specified directories, listed on a per subdirectory basis. Disk usage is reported in blocks. The numbers on the left indicate the number of blocks of disk space occupied by the directory. In our example, the /opt/SUNWits directory occupies 18456 blocks of disk space.

For example: du /opt could display something like the following:

18456   /opt/SUNWits
2       /opt/SUNWleo/include
4       /opt/SUNWleo

Removing Unwanted Applications

SEAS products can be uninstalled using one of the following:

The Product Registry. See "Uninstalling Using the Product Registry" for more information.
The jre command. See"Uninstalling Using the jre Command" for more information.
The pkgrm command. "Uninstalling Using the pkgrm Command" for more information.

Uninstalling Using the Product Registry

Use the Solaris Product Registry to uninstall applications you no longer need or use to free necessary disk space. See "Uninstalling Products From the Registry" for step-by-step instructions. You find the name of the uninstaller program in the right panel of the Product Registry after selecting the application to be removed in the left panel.

Uninstalling Using the `jre` Command

To remove a SEAS application using the jre command, you can run the uninstaller from the application.

For example, to remove Solstice DiskSuite, you would type the following command at the superuser system prompt:

jre --cp /var/sadm/prod/com.sun.DiskSuite/607900099 uninstall_DiskSuite_4.2.class

Uninstalling Using the `pkgrm` Command

You must be logged in as root and you must know the name of the packages that make up the application. For example, to remove Sun Directory Services, which consists of the packages SUNWlicsw, SUNWlit, SUNWsds, and SUNWsdsc, using the pkgrm command, you would type the following command:

pkgrm SUNWlicsw SUNWlit SUNWsds SUNWsdsc

To find the name of the application packages, use the command pkginfo | grep application_name. Then use the pkgrm command as indicated above.

Performing Pre-Installation Product Upgrades

The following SEAS products require specific pre-installation upgrades.

Upgrading DiskSuite 4.2

Upgrading DiskSuite 4.2 is complex. You should carefully read the entire Solstice DiskSuite 4.2 Installation and Product Notes, paying particular attention to the following sections.

Upgrading Sun Directory Services 3.1

When you installed SEAS 2.0, you received Sun Directory Services 3.1 and patch 106621-02. With SEAS 3.0, you receive a newer version of Sun Directory Services 3.1 which requires patch 106621-05. Installing the newer version of Sun Directory Services packaged with SEAS 3.0 does not automatically install patch 106621-05. This causes Sun Directory Services to run very slowly.

If you would like to upgrade from Sun Directory Services 3.1 in SEAS 2.0 to Sun Directory Services 3.1 in SEAS 3.0, you have the following two options:

Uninstall your Sun Directory Services patch 106621-02 for SPARC^TM, and 106622-02 for Intel, before installing Sun Directory Services 3.1.
Install Sun Directory Services 3.1, and after this is completed, uninstall patch 106621-02 for SPARC^TM and 106622-02 for Intel, and then install patch 106621-05 SPARC^TM and 106622-05 for Intel, which are located on your SEAS 3.0 product CD.

Upgrading PC NetLink 1.1 When TotalNET Access Server 5.2 Is Already Installed

When TotalNET Access Server 5.2 (TAS) is installed, and up and running at the time you install PC NetLink, the installer program forces you to exit the installation without completing it.

Refer to the PC NetLink 1.1 Release Notes on the SEAS 3.0 product CD for step-by-step instructions to stop the TAS 5.2 NetBEUI to enable the PC NetLink installation.
