About this book xiii
16. xiv IBM Rational ClearCase, ClearCase MultiSite, and ClearCase LT: Installation and Upgrade Guide
18. About release areas and Rational product installations
This manual describes various deployment options. However, each option can
be summarized as belonging to one of two types: release area deployment
options, and local (nonrelease area) deployment options.
v Release area deployment options use release areas. A release area is a
central location on your network, accessible by all hosts, that contains site
defaults used in the installation process. You create a release area by
choosing from a number of site default parameters. After the release area is
set up, any number of clients and servers can be installed from this release
area. Release area deployment options are usually described as ″enterprise
deployment″ options. They may include silently deploying Rational
ClearCase to a large number of server and client computers, or may include
downloading the software initially from the Web. If the installation uses a
release area, it can be described as an enterprise deployment option. For
more information, see Chapter 3, “Creating a release area,” on page 35 and
Chapter 4, “Installing servers and clients,” on page 45.
v Local deployment options do not utilize release areas, such as the Desktop
installation from CD image option. This installs both server or client
directly from the CD, rather than creating a release area. If you do not
create a release area, it is difficult to maintain your Rational ClearCase
installation. Therefore, this option is best used when installing Rational
ClearCase for evaluation purposes.
Select a deployment method
The IBM Rational Setup wizard provides the following deployment options
for your installation of IBM Rational products:
v Installation from a CD
v Installation from a Web download
v Enterprise deployment from a release area on your network
v Silent installation
For a description of these options and instructions to set up these
deployments, see “Configuring deployment” on page 35.
Installation road map

v Rational ClearCase LT needs enough disk space on
the server to contain the files and databases under
source control. The amount of space required
depends on the characteristics and use of the VOBs
and views.
v In addition to the free disk space required to load
the Rational ClearCase LT server, the server needs
0.5 to 1.0 MB for each user who will access the
Rational ClearCase Web interface or Rational
ClearCase Remote Client interface through the
Rational ClearCase LT server.
Additionally, snapshot view directories need enough disk space to contain all
files loaded into the snapshot views and all view-private files added to the
views. The amount of space required depends on the number and size of the
files in the views.
Any host that must contain VOB storage or view storage directories must
have enough disk space to contain the files and databases used for storage of
these directories. The amount of space required depends on the characteristics
and use of the VOBs and views.
Supported Rational ClearCase configurations in multiple language
environments
This section provides examples of supported Rational ClearCase
configurations for environments that use multiple languages. These examples
are listed in Table 8.
These are the requirements for multiple language environments:

Rational ClearCase servers and Windows workstation limits on
concurrent access
Windows workstations impose a limitation on concurrent access: a maximum
of 10 systems can access a Windows system simultaneously by means of file
system mounts or UNC names. If you anticipate this level of use, install
Windows server software on your primary Rational ClearCase servers.
Using Rational ClearCase and Windows domains
Rational ClearCase is a distributed client/server application; many operations
initiated on client hosts are completed by server processes elsewhere in the
network. Therefore, all Rational ClearCase hosts running Windows must
belong to a Windows domain or an Active Directory domain, except when
running a single-host evaluation copy of Rational ClearCase.
To use Rational ClearCase from a supported Windows host, you must log on
to a domain account (not a local, per-system user account). For more
information about Windows domains, see the IBM Rational ClearCase
Administrator’s Guide.
Operating system vendor Web site
You can find up-to-date information about Microsoft Windows operating
system issues at the Microsoft Web site, http://www.microsoft.com.
Setting up your environment for Rational ClearCase
The proper system infrastructure is critical if you are setting up a new
Rational ClearCase environment.
Chapter 2. Configuring your installation 15
32. Rational ClearCase host types
When you install Rational ClearCase on a computer, you specify whether to
configure the computer as a server or a client:
v A server is a reliable computer that supports VOBs and views that are
accessed by other computers on a local area network.
v A client is a computer on which a Rational ClearCase user works, typically
using one or more views to access VOBs on servers.
Various system tasks are assigned to server hosts. Use these descriptions to
understand and plan the number and types of each host you need to allocate
for your installation. You can designate a single computer as the server that
handles multiple server functions. For more information, see the IBM Rational
ClearCase Administrator’s Guide.
v Server host. Any host on which a VOB or view is created is a server host.
Some hosts may be dedicated servers on which client software is rarely
used. Other server hosts double as clients. All server hosts, and the registry
and license server host, must run Rational ClearCase.
v Registry server host. One host in the network acts as the Rational
ClearCase registry server host. Each host is assigned to a particular registry
server host at Rational ClearCase installation time. This host stores
access-path information for all the VOBs and views in the network. Rational
ClearCase client and server programs on all hosts communicate with the
registry server when accessing Rational ClearCase data. For information
about setting up a registry server host, see “Setting up the registry and
license server hosts for the first time” on page 28. For critical information
about upgrading and preserving your registry server data, see “Upgrading
Rational ClearCase hosts (full ClearCase only)” on page 64.
v License server host. One or more hosts in the network act as license server
hosts, authorizing and limiting Rational ClearCase use according to the
terms of your license agreement. Each host on which Rational ClearCase is
installed is assigned to a particular license server host and communicates
with that host periodically. For information about setting up a license server
host, see “Setting up the registry and license server hosts for the first time”
on page 28 and “Upgrading Rational ClearCase hosts (full ClearCase only)”
on page 64.
v Networkwide release host. One host in the network acts as the
networkwide release host. A directory on this host stores an entire Rational
ClearCase release that has been extracted from distribution media or
downloaded from the IBM Web site. When necessary, patches can be
applied to a release area to update the entire release with the latest
enhancements and defect fixes. The networkwide release host does not need
to run Rational ClearCase.
v IBM Web Platform (RWP) host. If you want to use the Rational ClearCase
Web interface, you need at least one RWP host.
16 IBM Rational ClearCase, ClearCase MultiSite, and ClearCase LT: Installation and Upgrade Guide
33. The RWP server host should have an additional 128 MB of physical
memory beyond what is required to support any VOBs and views on the
host. Unless the RWP host is the Rational ClearCase LT server, do not use
the RWP host as a VOB- or view-server host. RWP is installed automatically
with Rational ClearCase LT.
Attention: Installing RWP on a host that is already running another Web
server may result in a port conflict that can cause RWP or the other Web
server to fail on startup. Install RWP on a host that does not have to run
any other Web servers. If this is impossible, configure the other Web server
to use ports that are not being used by RWP. The default port number used
by RWP is 80. If you cannot use this port for RWP, you must configure
RWP to use another port by running the Site Preparation Tool (see
Chapter 3, “Creating a release area,” on page 35).
For more information about RWP, see the IBM Rational ClearCase
Administrator’s Guide.
Designating server and client hosts
If you are setting up a Rational ClearCase installation for the first time,
designate and configure the registry and license server hosts first. You can
install the registry and license server hosts on the same computer or on
different computers.
You must first set up the registry and license server hosts by creating a release
area and installing the hosts from that release area, using a set of site defaults
that you define. After you set up the registry and license server hosts, you
configure other server hosts where clients can create VOBs and views.
You must also designate the computers you use as clients. All Windows
clients can support dynamic views (if you have installed MVFS), local VOBs,
and snapshot views.
The features installed on a Rational ClearCase computer depend on site
defaults chosen by the administrator. Users can override these defaults in the
installation process.
VOB database schema versions
With this release, Rational ClearCase supports only VOB database schema
version 54. Schema version 53 is no longer supported.
If you are currently using schema version 53, you must reformat your VOBs
to use the newer format. Until you do, users cannot access VOB data after the
server has been upgraded to version 7.0. For more information about
reformatting your VOBs, see the IBM Rational ClearCase Administrator’s Guide.
For more information about this and other upgrade-related scenarios, see
Chapter 5, “Upgrading your Rational ClearCase installation,” on page 63.
Chapter 2. Configuring your installation 17
34. VOB database schema versions and MultiSite
If a server host contains replicated VOBs using Rational ClearCase MultiSite,
all servers of the same set of replicas should use the same VOB format.
Operational compatibility across versions of Rational ClearCase
Table 10 shows the compatibility paths when all hosts are not running the
same version of Rational ClearCase. In this tables, 'client' means Rational
ClearCase client software. Acomponent in a row can use a component in a
column if there is a yes at the intersection of the row and column. For
example, Table 10 shows that a 2003.06.00 view can use a 2003.06.00 VOB or a
7.0 VOB, but a 7.0 view cannot use a 2003.06.00 VOB.
Table 10. Compatibility: Views with VOBs
2002.05.xx VOB 2003.06.xx VOB 7.0 VOB
2002.05.xx view yes yes yes
2003.06.xx view no yes yes
7.0 view no no yes
As of this release, you must install the latest patches on client computers to
access all VOBs and views in your environment.
A version 7.0 client on Linux and the UNIX system can access a VOB on
Windows by using a snapshot view. However, the snapshot view storage
directory and the VOB storage directory must be on servers running version
7.0 or later.
Planning for Rational ClearCase MultiSite installation
You can install Rational ClearCase MultiSite only on Rational ClearCase server
hosts.
MultiSite need not be installed on all Rational ClearCase computers. In most
cases, only the following computers require MultiSite installation:
v Computers on which one or more replicated VOBs reside.
v Computers that belong to users with Rational ClearCase and MultiSite
administration responsibilities.
v Computers on which the shipping_server utility is used, even if no
replicated VOBs reside on that computer. Running shipping_server does
not require a MultiSite license. For more information about this utility, see
the IBM Rational ClearCase MultiSite Administrator’s Guide.
You do not need to upgrade all servers used by a set of replicas of a
particular VOB (a VOB family) at the same time.
18 IBM Rational ClearCase, ClearCase MultiSite, and ClearCase LT: Installation and Upgrade Guide
35. For upgrade considerations related to Rational ClearCase MultiSite, see
“Guidelines for upgrading Rational ClearCase MultiSite” on page 65.
Ensuring Rational ClearCase MultiSite compatibility with Rational
ClearCase
Rational ClearCase MultiSite is layered on Rational ClearCase. To use Rational
ClearCase MultiSite on a host running version 7.0 of Rational ClearCase, you
must be running version 7.0 of Rational ClearCase MultiSite. Rational
ClearCase MultiSite version 7.0 is fully compatible with Rational ClearCase
version 7.0 client and server hosts. Consider the following compatibility
guidelines:
v A Rational ClearCase MultiSite version 7.0 replicated VOB can reside on
any Rational ClearCase version 7.0 server host.
v Any Rational ClearCase version 7.0 client program can access and modify
any replicated VOB residing on a Rational ClearCase version 7.0 server
host. Other client VOB access is the same as that documented in
“Operational compatibility across versions of Rational ClearCase” on page
18.
Rational ClearCase, Rational ClearQuest, and IBM Shipping Server
considerations: The IBM Shipping Server is required for both Rational
ClearCase MultiSite and Rational ClearQuest MultiSite. It should be installed
only on those hosts that are responsible for replicating data to other sites.
Avoid configuring any one host to run the Shipping Server for both products,
because uninstalling either product from such a host will remove the Shipping
Server that is used by both products and render the remaining product
inoperable.
If you must install both Rational ClearCase MultiSite and Rational ClearQuest
with the Shipping Server on the same host, ensure that you perform the
following tasks:
v Install Rational ClearCase first.
v Uninstall both products if you ever uninstall either product. If you have
already installed Rational ClearQuest with MultiSite, uninstall only the
shipping server component from Rational ClearQuest, then install Rational
ClearCase with MultiSite.
Note: Administrators should be sure that site configuration files for typical
host systems do not specify installation of the IBM Shipping Server.
Any attempt to install Rational ClearCase on a host where Rational
ClearQuest and the Shipping Server is already installed will fail.
Chapter 2. Configuring your installation 19
36. Compatibility issues across MultiSite versions
The following sections describe compatibility restrictions and issues when
different sites are running different MultiSite versions.
Replica creation: There are compatibility restrictions on creating replicas. You
can replicate a VOB to a host running an earlier version of Rational ClearCase
MultiSite only if the feature level of the VOB is supported by the Rational
ClearCase release on the target host.
For example, if a host is running Rational ClearCase version 7.0 and has a
VOB whose feature level is 2, you can replicate that VOB to a host running
Rational ClearCase version 4.2. Similarly, if a host is running Rational
ClearCase version 7.0 and has a VOB replica whose VOB family feature level
is 3, you can export a replica-creation packet from that replica and import it
on a host running Rational ClearCase version 2003.06.xx. However, you
cannot import the packet on a host running Rational ClearCase version 4.2.
Rational ClearCase version 4.2 does not support feature level 3.
Replica synchronization: As long as VOB feature levels are compatible,
existing replicas hosted on systems running Rational ClearCase version 7.0
can synchronize with existing replicas on systems running either Rational
ClearCase version 4.x, 2002.05.xx, or 2003.06.xx. For more information about
feature levels, see the IBM Rational ClearCase MultiSite Administrator’s Guide.
Uninstalling Rational ClearCase MultiSite or the IBM Shipping Server: If
you are using Rational ClearCase MultiSite and the IBM Shipping Server on
the same computer and you uninstall either product, one may be partially
uninstalled and stop working. Uninstall both and reinstall the product that is
needed.
Installing the MultiSite Administration Web Console: To install the
MultiSite Administration Web Console, select the Rational ClearCase Web
Console component during a Rational ClearCase server installation.
After installation, you must give yourself write permission in the
ccase–home–dir directory.
Ensuring Rational ClearQuest compatibility with Rational ClearCase
Rational ClearCase and MultiSite version 7.0 can be integrated with Rational
ClearQuest in two different ways:
v If you are using Rational ClearCase with the Unified Change Management
(UCM) process, you can enable the Rational ClearQuest integration with
UCM and use it with Rational ClearQuest version 7.0.
v If you are using base ClearCase (that is, not using the UCM process), you
can integrate with Rational ClearQuest version 7.0 by using the Rational
ClearCase-Rational ClearQuest integration package.
20 IBM Rational ClearCase, ClearCase MultiSite, and ClearCase LT: Installation and Upgrade Guide
37. Note: You must run at least Rational ClearQuest version 7.0 on systems
where Rational ClearCase version 7.0 is installed.
See “Rational ClearCase, Rational ClearQuest, and IBM Shipping Server
considerations” on page 19.
Planning for Rational ClearCase installations on dual-boot computers
On a computer that can boot multiple Windows installations, do not install
Rational ClearCase in the same directory for any two installations.
If you install in the same directory, various identical Rational ClearCase
components are shared. Removing Rational ClearCase from that directory
disables Rational ClearCase for every version of Windows that uses the
common directory. Furthermore, when a common directory is used, it is not
possible to install different Rational ClearCase releases for each version of
Windows.
To avoid these problems, install Rational ClearCase in separate directories for
each version of the operating system.
Enabling remote administration
If you enable Rational ClearCase Remote Administration, any user who is
both logged on to another host and a member of the Rational ClearCase
administrators group can use the Rational ClearCase Administration Console
to change Rational ClearCase properties for clients and servers.
Remote administration capability is useful if, for example, you move your
license server to a new host. You can then change the settings for all clients
from a single computer.
These Rational ClearCase properties can be changed:
v Registry region
v License server
v Registry and backup registry servers
v MVFS cache sizes
If you do not enable Remote Administration, only the local user can change
that computer’s Rational ClearCase properties.
For more information, see the IBM Rational ClearCase Administrator’s Guide.
Ensuring compatible character-encoding systems
Because the interpretation of multibyte characters is controlled by a host’s
locale setting (established by using the Regional Options tool in the Windows
Control Panel), all tags in a region must use the same character set, and all
hosts in a region must use the same locale setting.
Chapter 2. Configuring your installation 21
38. Allocating licenses using ClearCase Licensing
You can use either ClearCase Licensing(formerly known as Atria licensing) or
Rational Common Licensing (powered by FLEXlm software) to allocate
licenses for Rational ClearCase version 7.0. This section provides an overview
of ClearCase Licensing. For more information about Rational ClearCase
license servers, see the IBM Rational ClearCase Administrator’s Guide.
The set of licenses is maintained on the license server. The network can have
one or more license servers. Each license server runs a Rational ClearCase
server process, and so must have Rational ClearCase installed. You set up
your license servers during the installation.
After you determine your initial license allocation (see “Allocating Rational
ClearCase licenses” on page 22), you obtain your Rational ClearCase license
keys from IBM support for Rational products, or from this location:
http://www.ibm.com/software/rational/support/licensing/ .
When calling customer support, be sure you specify that you are using
ClearCase Licensing or Atria licensing, as opposed to Rational Common
Licensing (powered by FLEXlm software).
Rational ClearCase and Rational ClearCase MultiSite implement an active-user
floating license scheme. For more information about how this scheme controls
a user’s access to Rational ClearCase and MultiSite are available in the
clearlicense reference page and in the IBM Rational ClearCase Administrator’s
Guide.
Rational ClearCase and MultiSite use the same license server.
Allocating Rational ClearCase licenses
Suppose that your organization has purchased 25 Rational ClearCase licenses.
You must decide how many license servers to use and how to allocate licenses
to them. Here are two examples.
v Use a single license server. In this case, request a single license
authorization code for 25 licenses. Create a single license database
incorporating this code.
A drawback of this strategy is its single point of failure. If your network’s
lone license server fails, no one is able to use Rational ClearCase. If you use
this strategy, select a reliable server and take this scenario into account
when constructing a disaster recovery plan.
v Use multiple license servers. In this case, request two license authorization
codes, perhaps one for 15 licenses and another for 10 licenses. Create two
license databases incorporating these codes, on two different servers.
22 IBM Rational ClearCase, ClearCase MultiSite, and ClearCase LT: Installation and Upgrade Guide
39. This strategy provides for more robustness. If the license server that holds
15 licenses fails, developers can still use Rational ClearCase.
Allocating MultiSite licenses
Each user of a replicated VOB must acquire both a Rational ClearCase license
and a MultiSite license; moreover, the two licenses must be acquired from the
same license server host. Therefore, plan your MultiSite licenses by analyzing
each current Rational ClearCase license server.
v If some or all users of a particular license server access replicated VOBs,
you must install MultiSite licenses on that license server.
v If all users access replicated VOBs, you must install the same number of
MultiSite licenses as Rational ClearCase licenses.
v If some users access unreplicated VOBs only, you do not need MultiSite
licenses for these users.
For example, a company has two sites, with 20 developers at site A and 5
developers at site B. The company has three VOBs at site A; two of them are
replicated to site B and one is not replicated. Five developers at site A access
only the unreplicated VOB, and the remaining 15 work in all VOBs. Therefore,
the company needs to purchase the following numbers of licenses:
Rational ClearCase
Site licenses MultiSite licenses
A 20 15
B 5 5
Note: This example assumes that you purchase a Rational ClearCase license
for each developer. If you have fewer Rational ClearCase licenses than
developers, you can purchase a proportionate number of MultiSite
licenses. For example, if site B purchased three Rational ClearCase
licenses, it would also purchase three MultiSite licenses.
Configuring Rational Common Licensing
This section provides an overview of the license management tools used with
IBM Rational products.
The IBM Rational License Management Guide describes the license management
tools and how to set up your license server configuration. It also describes the
different types of license keys and provides instructions for requesting,
installing, upgrading, and moving licenses. If you are installing IBM Rational
products for the first time, you must read this guide to understand the license
configurations available and the processes for obtaining and managing the
license keys.
Chapter 2. Configuring your installation 23
40. The following tools are used to manage Rational Common Licensing:
v AccountLink is a Web-based tool available from the IBM Rational Licensing
and Download Center and is used to obtain license keys.
v The IBM Rational License Server, which you must install from your IBM
Rational software product CD, monitors license access, tracks the number of
simultaneous users, and performs other tasks related to managing licenses.
v The License Key Administrator (LKAD) is used to import license keys on
target systems that run Rational products and change license configurations.
v The License Tools utility provides an interface to managing the FLEXlm
License Manager, the license server software.
Note: At the time of publication, AccountLink is the online license fulfillment
tool for IBM Rational software customers. In the future, AccountLink
will be replaced by the Rational License Key Center, an online system
that offers additional features and easier license key management. You
will access the new system, when it is available, using the same
location on the Web that is currently used for AccountLink:
http://www.ibm.com/software/rational/support/licensing/. This page
will provide all of the information and instructions you need to manage
license keys using the Rational License Key Center.
For more information about the License Tools utility, go to the IBM support
for Rational products Web site at http://www.ibm.com/developerworks/

42. Preinstallation tasks
Before you begin the installation, perform the following tasks:
1. Learn about the installation process.
2. Plan where you will install Rational ClearCase.
3. Make an installation plan.
4. Log in with appropriate privileges.
5. Define domain accounts.
6. Select and share a release area location.
7. Install Internet Explorer.
Understanding the installation process
Before planning your installation process, review the following summary of
the installation process.
You install Rational ClearCase by first creating a networkwide release area,
and then installing servers and clients from that release area, using specific
sets of site defaults. You set up your first release area by running setup.exe
from the Rational ClearCase CD.
1. You select a location for the release area, a shared directory on your
network. A release area contains at least one site default file and can
contain multiple site default files.
2. You run setup.exe from the Rational ClearCase CD and select the
Enterprise deployment option.
3. In the IBM Setup wizard, configure Rational ClearCase for your
installation by setting site defaults with the Site Preparation Tool. The site
defaults that you select determine the specific aspects of your Rational
ClearCase configuration, including MVFS performance settings, account
information, shortcuts, and so forth.
4. After you specify your site defaults, you are prompted to save your site
defaults file with a unique name, and also to add a meaningful description
for later reference. A shortcut icon will be created in your release area with
the name you chose for the site defaults file, excluding the file-name
suffix. The shortcut provides you with a convenient method of starting the
installation using the saved site defaults, at a future time.
5. The wizard creates your release area, and you may be prompted to restart
your computer.
6. After restarting, the Rational ClearCase Doctor and Server Storage wizard
run automatically. The Server Storage wizard does not run following a
client installation.
