Dynamic reconfiguration examples

ADD:: Figure 1 shows how to add a resource using dynamic reconfiguration. You can modify the VTAMLST source for the required major node and then use the VARY ACT,UPDATE=ALL|ADD command, including the member name of the data set containing the updated definition. Changes made in this way are permanent changes.

Alternatively, you can make temporary changes by creating a DR file and issuing the VARY DRDS command. These changes do not remain in effect when the NCP is regenerated and reloaded.

The MODIFY DR command cannot be used to add resources.

DELETE:: Figure 2 shows how to delete a resource using dynamic reconfiguration.

You can remove the PU and LUs from the VTAMLST definition and issue a VARY ACT,UPDATE=ALL command. Changes made in this way are permanent changes.

Alternatively, you can make temporary changes by creating a DR file and issuing the VARY DRDS command, or by using MODIFY DR commands. These changes do not remain in effect when the NCP is regenerated and reloaded.

MOVE:: Figure 3 shows how to move a resource using dynamic reconfiguration.

You can edit the VTAMLST definition to move the PU and LU definitions to the required locations and issue a VARY ACT,UPDATE=ALL command. Changes made in this way are permanent changes.

ADD a PU and LU:: Figure 4 shows how to add a PU and LUs by implicit dynamic reconfiguration.

Note: IMPLICIT is the default for the UPDATE operand on the VARY ACT command.
