Policy Items for ApplicationGroups

As described in Creating a New Application Group, there are two types of application groups: System Application Groups and Sysplex Application Groups.

Figure 1 shows the policy items that are displayed when a System Application Group is selected from the Entry Name Selection panel.

The unique policy items for application groups are as follows:

APPLGROUP INFO

This policy item displays the information about the application group, as specified when creating the application group. You can update the indicated values in this panel. See APPLGROUP INFO Policy Item for more information.

APPLICATIONS

When you select this policy item, a list of all applications in the SA z/OS enterprise is displayed, indicating which, if any, are associated with this application group. You can add applications to or remove applications from the application group. If the current application group has a resource name, the appropriate application resources are generated. According to the application group settings, the application resources (APL resources) are linked as members into the application group resource (APG resource). See APPLICATIONS Policy Item for more information.

TRIGGER

With this policy item, you can use the Trigger for ApplicationGroup panel to link the application group to a trigger so that all of its applications will be started or stopped depending on the defined trigger conditions. See TRIGGER Policy Item for more information.

SERVICE PERIOD

With this policy item, you can use the Service Period for ApplicationGroup panel to link a service period to the application group. Its resources are then automatically started up or shut down in the time frame specified by the service period. See SERVICE PERIOD Policy Item

RELATIONSHIPS

This policy item has the same functionality for entry types Application, ApplicationGroup, and Monitor Resource. For each application, application group, or monitor resource, you may specify several relationships. They will be used to automate the startup or stopping of those applications, application groups, and monitor resources. If you select this policy item in the Relationship Selection List panel, you can view existing relationships or define new relationships for the current application, application group, or monitor resource.

You define relationships between dependent resources and supporting resources. In the customization dialog, you define relationships always from the point of view of the dependent resource. So the resource that you have currently selected will become the dependent resource, when you define a new relationship.

See RELATIONSHIPS Policy Item for more information on viewing existing or defining new dependency relationships.

MESSAGES/USER DATA

This policy item has the same functionality as for applications and MVS components. It allows you to specify automated actions, such as issuing a command or a reply in response to a message. However, because application groups do not produce 'real' messages, this policy behaves differently. Currently only the special message ID, INGALERT, together with the command definitions assigned to it are honored by SA z/OS.

See MESSAGES/USER DATA Policy Item for more information about how to specify this policy item.

RESOURCES

This policy item allows you to select resources for current application group and set their preferences or names.

The panels displayed look different depending on the nature of the current application group. See Scenarios on How to Use the Customization Dialog and RESOURCES Policy Item for information on how to work with these different panels.

GENERATED RESOURCES

This policy item displays a list of all resources that are generated for the current application group and for the applications that are linked to this application group. See GENERATED RESOURCES Policy Item for a description of the Generated Resources panel.

MEMBER OF

As resources that are derived from application groups can be members of other APG resources, this policy item lets you see those resources that the current application group resource is a member of. See the Member of panel in MEMBER OF Policy Item for more details.
