This task guides you through the steps to configure the client scheduler.
Your Tivoli® Storage Manager administrator can schedule Tivoli Storage Manager to perform tasks automatically.
For example, you can automatically back up files at the end of each day or archive some of your files every Friday. This procedure, which is known as central scheduling, is a cooperative effort between the server and your client node. Your administrator associates clients with one or more schedules that are part of the policy domain that is maintained in the server database. The Tivoli Storage Manager administrator defines central scheduling on the server and you start the client scheduler on your workstation. After you start the client scheduler, further intervention is not necessary.
With client scheduling, you can perform the following tasks:
- Display information about available schedules.
- Display information about work that the schedule has completed.
Modify scheduling options in the client options
file (dsm.opt).
Modify scheduling options
in the dsm.sys file.
The following information
is a comparison of the client acceptor daemon-managed services and
the default traditional scheduler services methods.
- Client acceptor daemon-managed services
-
- Defined by using the managedservices schedule option and started with client acceptor daemon services (dsmcad).
- The client acceptor daemon starts and stops the scheduler process as needed for each scheduled action.
- Requires fewer system resources when idle.
- Tivoli Storage Manager client options and Tivoli Storage Manager server override options are refreshed each time the client acceptor daemon services start a scheduled backup.
- Cannot be used with SESSIONINITiation=SERVEROnly backups.
- Tivoli Storage Manager traditional scheduler services
-
- Started with command dsmc sched command.
- Remains active, even after scheduled backup is complete.
- Requires higher use of system resources when idle.
- Tivoli Storage Manager client options and Tivoli Storage Manager server override options are only processed once when dsmc sched is started.
- You must restart the scheduler process for updated Tivoli Storage Manager options to take effect.
The Tivoli Storage Manager client
acceptor daemon can manage the scheduler. In this case, the CAD serves
as an external timer for the scheduler. When the scheduler is started,
it queries the server for the next scheduled event. The event is either
run immediately or the scheduler exits. The CAD restarts the scheduler
when it is time to run the scheduled event, which reduces the number
of background processes on your workstation and resolves memory retention
problems that can occur when the scheduler is run without CAD management.
The Tivoli Storage Manager Client
Acceptor service (CAD) can manage the scheduler. In this case, the
CAD serves as an external timer for the scheduler. When the scheduler
is started, it queries the server for the next scheduled event. The
event is either run immediately or the scheduler exits. The CAD restarts
the scheduler when it is time to run the scheduled event. This reduces
the number of background processes on your workstation and resolves
memory retention problems that can occur when the scheduler is run
without CAD management.
You cannot use the dsmcad for scheduling when you set the sessioninitiation option to serveronly.
Use the managedservices option
in your client system-options file (dsm.sys)
to specify whether the CAD manages the scheduler.
Use the managedservices option
in your client options file (dsm.opt) to specify
whether the CAD manages the scheduler.
Perform the following steps to configure the CAD to manage the client scheduler:
- From the Tivoli Storage Manager GUI, select , and then select the web Client tab. Select the Schedule option in the Managed Services options section. If you also want the CAD to manage the web client, select the Both option.
- Start the Client Acceptor.
- In the Tivoli Storage Manager GUI, select and click Next.
- Read the scheduler wizard screen text and click NEXT.
- Select Install a new or additional scheduler and click Next.
- Specify a name for the scheduler; the default name is TSM Client Scheduler. Select Use the Client Acceptor daemon (CAD) to manage the scheduler and click Next.
- Specify a name for the client acceptor service that you want to manage the scheduler. If the CAD is already installed for use by the web client, select that CAD name from the drop-down list. Otherwise, type the name that you want to assign to this CAD. The default name is TSM Client Acceptor. Click Next.
- Follow the instructions on the remaining screens to complete the configuration.
- If the sessioninitiation option
is set to serveronly in your client options file
(dsm.opt), the client setup wizard and scheduler
service might be unable to initiate authentication with the Tivoli Storage Manager server.
To avoid this problem, ensure that the Contact the TSM
Server to validate password check box on the TSM
Authentication page is cleared.
- In the Service login options window, select
the Automatically when Windows boots option
to have the service automatically started when Windows starts so that your schedules are
run.
- You can also use the Scheduler Service Configuration
utility. The Scheduler Service Configuration utility must be run from
an account that belongs to the Administrator/Domain Administrator
group. You can start multiple client scheduler services on your system.
- If you are having the CAD manage your schedule,
start the CAD service, but do not start the scheduler service. The
scheduler service is started and stopped automatically by the CAD
service as needed. If you are not managing the schedule with the CAD,
then you can use the services Control Panel or the net start command
to start the Scheduler service.
- If you include files for encryption, ensure that the encryptkey option is set to save is in the options file. This option is set by selecting Save Encryption Key Password Locally on the Authorization panel in the preference editor. Setting this option enables unattended scheduled services. If the encryption key has not been previously saved, you must perform an attended backup of at least one file so that you get the encryption prompt and you can save the key.
