8.3 Configuring the Standalone zRule Execution Server for z/OS (one zRule Execution Server for z/OS/one console) For every type of setup, you must initially configure one Standalone zRule Execution Server for z/OS with one console. This configuration is required when setting up the other configurations that are described later in this chapter. Those sections refer to completing this configuration before setting up the other types of environments. 8.3.1 Defining a new subsystem for zRule Execution Server for z/OS The first step for the configuration of the Standalone zRule Execution Server for z/OS is to define the subsystem in which the new instance runs. The systems programmer must perform this task. Figure 8-7 shows the following command that must be run, where ++HBRSSID++ is the Subsystem ID that was set in Table 8-4 on page 228: SETSSI ADD,SUBNAME=++HBRSSID++ Figure 8-7 Setting the zRule Execution Server for z/OS instance subsystem name
