The most common types of operator tasks are those associated with monitoring and controlling the network. The portion of a network that you can control varies from one organization to another.
Sphere of control refers to the portion of the network you control and what operations you can perform on that portion of the network. Your sphere of control is limited by any restrictions on which portions of the network you can affect and which commands you can issue. Within your sphere of control, you can both monitor and control VTAM®'s domain. This means that you can view what is happening in your network and change network status as needed.
Your individual network will differ from that of other operators. The following information about monitoring and controlling the domain of VTAM includes a few examples of results of commands issued by an operator in the sample network.
- Two sessions. One is between application CICS01 and logical unit L3A3767A. The other is between CICS01 and logical unit L3A3278A.
- Two cluster controllers. They are physical units P3A3767A and P3A3274A.
