Configuring the client to use the client acceptor service to manage the scheduler

One of the most effective ways of managing the client scheduler is to use the Tivoli® Storage Manager Client Acceptor service (CAD). You must configure the client to use the client acceptor service to manage the scheduler.

Before you begin

If you include files for encryption, ensure that the encryptkey option is set to save in the options file. This option is set by selecting Save Encryption Key Password Locally on the Authorization tab in the preference editor. Setting this option enables unattended scheduled services. If the encryption key was not previously saved, you must run an attended backup of at least one file so that you get the encryption prompt to save the key.
You cannot use the CAD for scheduling when the sessioninitiation option is set to serveronly.

About this task

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 action 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 client acceptor service is also known as the client acceptor daemon.

Procedure

Complete the following steps to use the CAD to manage the client scheduler:
1. From the Tivoli Storage Manager GUI, select Edit > Preferences.
2. Click the Web Client tab.
3. In the Managed Services Options field, click Schedule. If you also want the CAD to manage the web client, click Both option.
  Tip: You can also use the managedservices option in the client system-options file (dsm.sys) to specify whether the CAD manages the scheduler.
4. Start the client acceptor daemon by running the following command on the command line:
```
dsmcad
```
Complete the following steps to use the CAD to manage the scheduler on the Windows client:
1. In the Tivoli Storage Manager backup-archive client GUI, click Utilities > Setup Wizard > Help me configure the TSM Client Scheduler and click Next.
2. Read the information in the TSM Scheduler Wizard page and click Next.
3. In the Scheduler Task page, select Install a new or additional scheduler and click Next.
4. In the TSM Scheduler Name and Location page, specify a name for the client acceptor service that you want to manage the scheduler. Then, select Use the Client Acceptor daemon (CAD) to manage the scheduler and click Next.
5. If the CAD is already installed for use by the web client, select that name of the CAD from the drop-down list in the Web Service Name page. Otherwise, type the name that you want to assign to this CAD. The default name is TSM Client Acceptor. Click Next.
6. Follow the instructions on the remaining screens to complete the configuration.
  Use the following information to help you complete the wizard pages:
  - If the sessioninitiation option is set to serveronly in the client options file (dsm.opt), the client configuration 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.
  - For the CAD-managed scheduler, select Manually when I explicitly start the service in the Service login options page.
7. Start the CAD service from the Services Control Panel, but do not start the scheduler service. The scheduler service is started and stopped automatically by the CAD service as needed.

Results

Tip:

You can also use the managedservices option in the client options file (dsm.opt) to specify whether the CAD manages the scheduler.
If you do not use the CAD to manage the scheduler, select Automatically when Windows boots in the Service login options window. This setting starts the service automatically when Windows starts so that your schedules are run automatically. Alternatively, you can use the Services Control Panel or the net start command to start the Scheduler service.
You can also use the Scheduler Service Configuration utility (dsmcutil.exe) to configure the scheduler. 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.
