<div class="section"><h4 class="sectiontitle">Compatibility differences</h4><p>If you are currently using
|
|
the character-based interface control groups and they do not reference the
|
|
system policy (*SYSPCY), archive policy (*ARCPCY), backup policy (*BKUPCY)
|
|
and do not share media policies among control groups, then using the BRMS
|
|
plug-in should have no functional impacts to your character-based control
|
|
groups. If this is not true, read the following information:</p>
|
|
<div class="p">The backup
|
|
and archive policies created by the BRMS plug-in can be viewed and run from
|
|
the character-based interface. Also, control groups created from the character-based
|
|
interface can be viewed and edited via the BRMS plug-in backup and archive
|
|
policy properties. A message will be presented to the user when a character-based
|
|
created or edited control group is about to be changed by the BRMS plug-in;
|
|
the user will have the opportunity to cancel the operation or continue. However,
|
|
changing control groups created on the character-based interface using the
|
|
BRMS plug-in is not recommended unless you understand the following: <ul><li>The BRMS plug-in backup and archive policies are designed to be independent
|
|
of each other. Thus, if you make changes to one policy, it will not affect
|
|
the others. To ensure this independence, control groups updated with the
|
|
BRMS plug-in will have all references to the character-based interface system
|
|
policy (*SYSPCY), archive policy (*ARCPCY), and backup policy
|
|
(*BKUPCY) removed. These references will be resolved and replaced with the
|
|
actual values when the backup policy is saved by the BRMS plug-in. The archive
|
|
policy, backup policy, or system policy do not affect backup or archive policies
|
|
created or edited by the BRMS plug-in. The exceptions to this are the network
|
|
function, sign off exceptions, and subsystem to check controls in the system
|
|
policy, which are used by the BRMS plug-in.</li>
|
|
<li>The BRMS plug-in hides the media policy from the user (no BRMS plug-in
|
|
functions exist to show or edit media policies). Media policy attributes
|
|
are indirectly shown and edited through backup and archive policy properties.
|
|
As mentioned earlier, the BRMS plug-in backup and archive policies are designed
|
|
to be independent of each other. To ensure this, the BRMS plug-in will create
|
|
a new media policy based on the currently used one if the control group being
|
|
edited contains a media policy that is used by other control groups or is
|
|
a shipped BRMS media policy. If a new media policy is created, the control
|
|
group will be changed to use the new one.</li>
|
|
<li>When you create a new backup or archive policy using the BRMS plug-in,
|
|
it will use a new media policy that is dynamically created. </li>
|
|
<li>Changes made to other, non-IBM supplied policies are reflected in the
|
|
BRMS plug-in.</li>
