6.5 Naming conventions Naming conventions make the runtime environment more comprehensible. A consistent naming convention helps standardize the structure of the environment and allows for easy expansion of the environment and each component. Naming conventions should be developed, established, and maintained for the hardware and networking infrastructure, as well as the WebSphere Application Server infrastructure, applications, and resources. When it comes to naming, most companies have already developed a working naming convention for existing infrastructure, and it is usually best to adhere to the existing convention instead of trying to invent new one specific to WebSphere. Because naming conventions are also related to many different aspects of a company, they will vary depending on the characteristics of the environment. With a proper naming convention, you should be able to understand the purpose of an artifact by just looking at its name. When you develop a naming convention, take into consideration which hardware and software components are affected and what naming restrictions apply. On many systems there are naming restrictions in terms of specific characters and length of the names. In a heterogeneous environment this might become a pitfall. Experience shows that it is best to avoid any special or national language specific characters in the names. 6.6 Planning for the load balancer Before starting the installation of the load balancer, several planning tasks must be finished. The first pre-requisite to install the Load Balancer is that the detailed network planning for your environment is finished and that you have an exact understanding of the data flow in your environment. Edge Components V7.0 are shipped with two versions of the Load Balancer: ► Load Balancer for IPv4 ► Load Balancer for IPv4 and IPv6 Note: Several features of the Load Balancer for IPv4 were deprecated when WebSphere Application Server V6.1 was announced. For a detailed list of the deprecated features see the following Web page: http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm. websphere.nd.multiplatform.doc/info/ae/ae/rmig_depfeat.html#depv61 Unless you have a specific requirement to use the Load Balancer for IPV4 you should consider the newer Load Balancer: Load Balancer for IPv4 and IPv6. 184 WebSphere Application Server V7.0: Concepts, Planning, and Design
6.6.1 Installation 6.6.2 Configuration Before starting with the installation, consult the IBM Information Center for the type of Load Balancer you will install to ensure that all the required hardware and software pre-requisites are met. The hardware and software requirements for the Edge Components can be found at the following Web page: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27012372 The installation for both types of Load Balancer is done through the platform-specific package manager. Detailed installation documentation for the Load Balancer Product can be found at the following Web pages: ► For Load Balancer for IPv4, see the following Web page: http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm. websphere.edge.doc/lbip4/LBguide.htm#HDRINSTALL ► For Load Balancer for IPv4 and IPv6, see the following Web page: http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm. websphere.edge.doc/lb/info/ae/tins_installlb.html After the installation of the product you have to configure the Load Balancer for your environment. The two available Load balancers provide a wide variety of configuration options. You have multiple ways to configure the product and how the Load Balancer should forward packets. The following sections give an overview about some of these configuration tools and configuration options. Configuration interfaces: Load Balancer for IPv4 The Load Balancer for IPv4 provides the following methods for configuration: ► Command line ► Graphical User Interface (GUI) ► Configuration Wizard Configuration interfaces: Load Balancer for IPv4 and IPv6 The Load Balancer for IPv4 and IPv6 provides the following methods for configuration: ► Command line ► Scripts ► GUI ► Configuration Wizard Chapter 6.
