Application server naming conventions

Before you install a new WebSphere Application Server for z/OS environment, it is important to carefully plan the naming convention. Your naming convention should be able to grow with the system when you increase the number of cells, nodes, servers, and clusters. It should also be able to accommodate Sysplex and LPAR names, as well as instances such as test, integration, and production stages in the environment.

Application servers are like IMS™ or CICS regions.

Avoid trouble: For a global resource serialization (GRS) ring to attach one or more monoplexes to a sysplex environment, the cell name of any servers running in any of the monoplexes must be unique within the entire GRS environment. This requirement means that the cell name of a server running in any of the monoplexes:

If we have servers with duplicate cell names within the GRS environment, WebSphere Application Server cannot differentiate between the sysplex cell and the monoplex cell, and treats both servers as part of the same cell, This inaccurate cell association typically causes unpredictable processing results.gotcha

The product environment consists of a number of address spaces which require the installation to manage security profiles, workload classification constructs, and so on. To create, manage, and recognize application servers, it may be helpful to create a template for naming the servers and server instances. We can find an example template in the Sample configuration and naming conventions topic.

It is also important to plan the naming conventions for the data sets carefully.
