Performance Tuning for Content Manager

Chapter 1. Content Manager 9

The Resource Manager is implemented as a Java 2 Enterprise Edition (J2EE™)

Web application, and requires the WebSphere Application Server as its

J2EE-compliant application server. WebSphere Application Server must be

installed and configured before you begin the installation of the Content Manager

Resource Manager component.

You can find more about WebSphere Application Server and about how it

interacts with Content Manager by browsing through the documentation that is

available through the WebSphere Application Server information center, which is

located at:

IBM HTTP Server

Client requests to store or retrieve documents are communicated by HTTP to the

Web server. The Web server then packages the request to be sent to the

Resource Manager. Optionally, client configuration files (*.ini and *.property) may

be published on the Web server so that all clients in the enterprise share a

common and centrally maintained configuration.

Tivoli Storage Manager

Tivoli Storage Manager is a client/server product that provides storage

management and data access services in a heterogeneous environment. It is

provided so that you can store objects, long term, on a storage device other than

the fixed disks that are attached to the Resource Manager. Tivoli Storage

Manager supports a variety of communication methods and provides

administrative facilities to schedule backup and storage of files.

Tivoli Storage Manager Client

The Resource Manager server uses the Tivoli Storage Manager Client APIs,

which are installed with the Tivoli Storage Manager Client, to access the Tivoli

Storage Manager server. These APIs provide connectivity between the Resource

Manager server and the Tivoli Storage Manager server and can be programmed

to centrally administer storage.

1.2.3 Content Manager clients

The Content Manager clients are the interface that users use to manage and

work in the Content Manager system. Content Manager offers the following

out-of-box clients:

 System administration client

 Client for Windows, a dedicated Windows client that runs on Windows 2000,

Windows Server® 2003, or Windows XP

10 Performance Tuning for Content Manager

 eClient, a browser-based client that runs on Netscape or Internet Explorer®.

Your choice might be influenced by the portability of the Web client versus the

functionality of the Windows client.

In addition to the out-of-box clients, Content Manager also offers the following

possible choices of clients:

 Portal client

 Custom client

System administration client

The System administration client is one of the Content Manager clients. It

oversees and manages the entire Content Manager system.

Through the system administration client, you can:

 Define your data model.

 Define users and their access to the system.

 Manage storage and storage objects in the system.

Figure 1-4 shows the system administration client and its relationship to the

Library Server and the Resource Manager.

The system administration client component can be installed on Windows, AIX,

Solaris, or Linux. It can be installed where other components are installed or on a

separate workstation. As a security measure, the system administration client

communicates with the Resource Manager through the Secure Sockets Layer

(SSL) interface.

Client for Windows

The Client for Windows is installed only on a Windows system. It enables users to

import, view, store, and retrieve documents. The Client for Windows can also be

run in a Terminal Server Edition (TSE) environment. The number of users who

can be supported on any one TSE server depends on the memory, processing

power, and other factors on the server, as well as on the amount of activity for

each client user. All client actions are supported in this environment, except for

scanning documents into the system (which must be done on a local workstation).

Figure 1-5 shows the relationship between the Content Manager Client for

Windows and the other Content Manager components (Library Server, Resource

Manager, and system administration client).

eClient

eClient can be installed on a Windows, AIX, or Solaris system. eClient is a

browser-based client that provides out-of-the-box capabilities for Content

Manager systems, similar to that of the Windows client. Import and export can be

done using the eClient wizards. Document and folder organization functions are

available through eClient. The eClient viewer provides page navigation functions

such as next, prev, last, goto, zoom in, and zoom out.

The application displays the first page of a document as soon as it is available

without waiting for the entire document to download. This improves the response
