2.4.2 New Commands

To support the dependent node architecture, seven new commands were added. These commands can be divided into two groups. The first group must only be executed with root permission on the Control Workstation. The second group can be executed by any user on any standard RS/6000 SP node.

Table 5 shows a list of commands of the first group:
