Following are brief summaries of the key parameters on the system policy display. These are the parameters that you are most likely to change.

The default Media policy that is configured at installation time and used by the system policy is called FULL. The FULL media policy instructs BRMS to use full backups with a 35 day retention period. Another BRMS-configured option is INCR, which instructs BRMS to use incremental backups with a 14 day retention period. You can also use the Save System (SAVSYS) special value, which instructs BRMS to retain media for 1725 days (5 years) after a system save. You can change the default media policy to another BRMS-configured policy or to one that you created. To do so, press F4 from the Media policy field and select from the available list.

The device name listed in the Devices field refers to the default device that is selected by BRMS at the time of installation. If you have more than one device attached to your system, BRMS uses the fastest and most automated one that is attached to your system. If you do not want to use the default device, you can select F4 from this prompt to select from a list of additional devices. The devices in this list include other devices that are attached to your system at time of installation, and any others you add after that.

The Home location for media field specifies the on-site home location for media that is managed by BRMS. *HOME is the default value for this prompt. BRMS also provides an off-site default location, called VAULT. To change the default value, place your cursor in the Home location for media field and press F4 to prompt a list of locations.

The Media class field specifies the default media class that is used by BRMS. BRMS uses media classes to describe different types of media. BRMS bases its definitions on characteristics such as tape density, capacity, label information, error allowance, and shared status. Be sure that the media class you use is compatible with the device in the same policy. If you do not want to use the BRMS default location, you can select from a list of locations by pressing F4 from this parameter.

The default value for the Sign off interactive users parameter is *NO. If you select *YES, BRMS sends warning messages at the following intervals:

However, there is no signal that indicates when users have signed back on the system. If this is a problem, you might want to consider stopping the subsystems. It is recommended that you keep the value set to *NO at this parameter and manage signoff of the interactive users from the backup control group attributes.

You will want to exempt specific users from being signed off, specifically the user signed on to the console monitor. For more information about the console monitor, refer to Console Monitoring. You would use option 2 from the BRMSYSPCY menu to specify any signoff exceptions.
