IBM Tivoli OMEGAMON XE V3.1 Deep Dive on z/OS

40 IBM Tivoli OMEGAMON XE V3.1 – Deep Dive on z/OS

3.1 Planning for installation

The successful installation of an enterprise monitoring system takes careful

planning. This section provides the steps necessary to plan this installation.

Multiple factors must be considered before you begin the installation of the

OMEGAMON infrastructure. Each environment has its own prerequisites.

These steps include:

򐂰 3.1.1, “Checking the requirements” on page 40

򐂰 3.1.2, “Implementation options” on page 42

򐂰 3.1.3, “Overview of the installation and configuration process” on page 43

3.1.1 Checking the requirements

For IBM Tivoli OMEGAMON XE, we discuss requirements for hardware,

software, and networks.

Hardware and software requirements

The complete system requirements, such as for software level and storage, are

supplied in the products Program Directory. Refer to the appropriate Program

Directory for the products that you are installing. You should also review the

current Preventive Service Planning (PSP) information and acquire all of the

necessary maintenance that is available for the product.

The driving system that is used to install IBM Tivoli OMEGAMON XE can run in

any hardware environment that supports z/OS V1.4, 5694-A01 or later and IBM

System Modification Program/Extended (SMP/E) for z/OS and OS/390 V3.2.0,

5655-G44 or later. Our environment runs z/OS 1.5.

򐂰 For Tivoli Enterprise Portal Server: This can run on either a Windows-based

system or Linux running on zSeries (with IBM Tivoli Monitoring V6.1).

Recommended hardware for a Windows-based system is an Intel® system

capable of running Windows XP Pro, Windows 2003, or Windows 2000.

Software: Windows XP Professional Edition with SP 1 (or higher) or Windows

2000 with SP 3 (or higher).

򐂰 Desktop or browser client:

Tivoli Enterprise Portal desktop client requires Sun™ Java™ V1.3.1 with

fixpack 4 or later, or V1.4.2 with fixpack 7 or later.

Tivoli Enterprise Portal browser client requires Internet Explorer 6 (or higher)

with Java Plug-in (same Java release levels as above).

Network requirements

While networking can be considered a hardware component, it does require

some attention. The OMEGAMON infrastructure typically uses three

communication protocols: IP (UDP), IP.PIPE (TCP), and SNA. These protocols

have different requirements in order to properly work with the infrastructure

components.

򐂰 IP.PIPE specifies the use of the TCP/IP protocol for underlying

communications.

򐂰 IP specifies the use of the UDP (User Datagram Protocol), which is a

packet-based, connectionless protocol.

򐂰 SNA specifies the use of Systems Network Architecture (SNA) Advanced

Program-To-Program Communications (APPC).

See the program directory and Getting Started with IBM Tivoli OMEGAMON on

z/OS, SC32-9491, for more details.

To illustrate use of TCP/IP communication with IBM Tivoli OMEGAMON XE on

z/OS, Example 3-1 is an excerpt of the command NETSTAT in our environment.

Note: If IBM Tivoli OMEGAMON XE on z/OS is used with the IBM Tivoli

OMEGAVIEW product, they should both be installed in the same CSI target

and distribution zones. This ensures that the maintenance level of the

ITMS:Engine and Tivoli Enterprise Monitoring Server components, which are

used by both products, is at the same level. If they are installed in different CSI

zones, you should check to ensure the maintenance levels of the ITMS:Engine

and Tivoli Enterprise Monitoring Server components in both zones are the

same or at a compatible level.
