You can use either the client acceptor service or the traditional scheduler service to manage the Tivoli® Storage Manager scheduler. A comparison of these methods is provided.
The following table shows the differences between the client acceptor-managed services and the default traditional scheduler services methods.
Client acceptor-managed services | Tivoli Storage Manager traditional scheduler services |
---|---|
Defined by using the managedservices
schedule option and started with client acceptor services. The client acceptor daemon is started with the dsmcad command The client acceptor service is started as a Windows service |
Started with command dsmc sched command. |
The client acceptor service starts and stops the scheduler process as needed for each scheduled action. | Remains active, even after scheduled backup is complete. |
Requires fewer system resources when idle. | Requires higher use of system resources when idle. |
Tivoli Storage Manager client options and Tivoli Storage Manager server override options are refreshed each time the client acceptor services start a scheduled backup. | Tivoli Storage Manager client options and Tivoli Storage Manager server override options are only processed after dsmc sched is started. |
Cannot be used with SESSIONINITiation=SERVEROnly backups. | You must restart the scheduler process for updated Tivoli Storage Manager options
to take effect. Important: If you run the client scheduler
on the command line, the scheduler does not run as a background service.
Tip: Restart the traditional scheduler periodically to free
system resources previously used by system calls.
