SET QUERYSCHEDPERIOD (Set query period for polling client nodes)

Use this command to regulate how often client nodes contact the server to obtain scheduled work when it is running in the client-polling scheduling mode.

Each client can set its own retry period at the time its scheduler is started. You can use this command to override the value specified by all clients that can connect with the server.

If client nodes poll more frequently for schedules, the nodes receive changes to schedules more quickly. However, increased polling by the client nodes also increases network traffic.

You can issue the QUERY STATUS command to display the value for the period between schedule queries. At installation, Tivoli® Storage Manager is configured so that each client node determines its own value for this setting.

Privilege class

To issue this command, you must have system privilege.
