TPCF lets you dedicate a device to a system so only jobs on that system can use the device. To dedicate a device, specify the DEDICATED parameter on the VARY command. For example, to dedicate device 01A0 to the local system, issue the following command:
VARY 01A0 DEDICATED
When you dedicate a device to the local system, TPCF varies the device offline on the external systems and allows the device to be allocated only by local jobs. In addition, the dedicated device is preferenced over other devices so that they are more likely to be used first for local jobs. However, if a job on another system cannot allocate a device, then TPCF may allow this device to be placed in the offline device list.
TPCF also intercepts all VARY ONLINE commands from the external systems and suppresses them for dedicated devices so that these devices are not varied online accidentally to other systems.
You must use the VARY NOTDEDICATED command to release a dedicated device. NOTDEDICATED status causes the device to be varied online on external systems.
