Deciding the type of runtime environment

A runtime environment is a logical grouping of runtime libraries that are referenced by started tasks as the tasks run on a z/OS® image. After you determine which z/OS images must be monitored and you decide whether to deploy the monitoring server and monitoring agent in the same address space, in separate address spaces, or on different systems, the next step is to decide the types of runtime environments that are appropriate for the components that you plan to deploy on your z/OS images.

You must define a runtime environment on each z/OS LPAR that is to be monitored.

The OMEGAMON shared documentation, Version 6.3.0 Fix Pack 2 and above describes how to set up a runtime environment and includes various configuration scenarios.

After you review the information about runtime environments, you can decide the type of runtime environment configuration that best suits your configuration. In most cases, you start with one full or base type and sharing types (that share either the full or base runtime environment) for subsequent z/OS images that you monitor. For each runtime environment, gather the following information:
Table 1. Defining your runtime environments
Value Description Value for your configuration
Runtime environment name Unique identifier of up to 8 characters.  
Runtime environment type Explained in OMEGAMON shared documentation, Version 6.3.0 Fix Pack 2 and above  
The base or full runtime environment associated with a sharing runtime environment For a sharing runtime environment type, list the name of the base or full runtime environment from which the sharing obtains its base library information.  
Runtime environment description Information for use at your installation.  
Security system for the runtime environment For each runtime environment, PARMGEN prompts you for a security system. You can specify None, RACF, TSS, or NAM. Do not specify the security system during initial configuration, but instead return to PARMGEN to do it later. Note the type of security system that you want to use for the runtime environment.  
VTAM® network ID A VTAM network ID is required for any monitoring server on z/OS, but is optional for a monitoring server on a distributed system.  
TCP/IP host name The TCP/IP host name of the z/OS system where you create the runtime environment. To obtain the host name and IP address values, enter TSO HOMETEST on the command line of the z/OS system.  
IP address The IP address of the z/OS host system where you create the runtime environment.  
Started task The started task of the TCP/IP server for the z/OS system.  
Port number The address of the IP port. The default is 1918.  

When you use PARMGEN to configure the OMEGAMON® for IMS on z/OS monitoring agent, you define a runtime environment of a certain type, which determines the number and types of runtime libraries that are required.
