Starting DFS server daemons

DFS server daemons are started in any of the following ways:

During the system IPL
Using the MODIFY DFS operator command
Using the START operator command.

Based upon the control files for dfscntl set up by the DFS administrator, all of the DFS server daemons can be automatically started when the DFS started task is started.

The DFS daemons can all run in one address space (except for possibly dfskern) which is a started task (default name DFS). A user with z/OS® operator privileges can start and stop the DFS started task. The DFS server address space can be started automatically during system IPL. To start the DFS server address space, use the z/OS START command as shown in the following example.

start dfs

Ideally, the daemons run continuously in the background and do not need to be started or stopped again. However, you might start the DFS server daemons manually in certain situations, for example, if a daemon ends abnormally. You can use the MODIFY operator command to manually start or stop the DFS server daemons.

Each of these alternatives is discussed briefly in the following sections. For complete details, see z/OS system commands.
