The following fields are displayed on theApplication Group Information help panel for MOVE groups.

APG Type

This field shows whether the application group belongs to a SYSTEM or a SYSPLEX.

APG Nature

This field shows the availability behavior of application groups and their applications members. MOVE means that the group is considered to be available when one of its members is available.

APG Model

This field defines the model of an application group of nature MOVE or SERVER.

1: The move behavior of the group and its members is defined by preference values.
2: The move behavior of the group is selected from a list of move scenarios and by assigning roles to the group members.

Automation Name

This field specifies under what name the application group can be monitored and what name is used as the first part of the resource name when generating resources for this application group. The maximum length is 11 characters.

If you blank out this field, no resource will be generated for the application group, and no resources can be collected into this application group using the RESOURCES policy.

An application group resource is generated when the application group is linked to a system or a group:

For an application group of type SYSTEM, a resource is generated when the application group is linked to a system, either in the application group's WHERE USED policy or in the system's APPLICATION GROUPS policy.
For an application groups of type SYSPLEX, a resource is generated when the application group is linked to a group, either in the application group's WHERE USED policy or in the group's APPLICATION GROUPS policy.

Behavior

This field specifies whether requests to change the desired status of the application group are propagated to the group members. If yes, specify ACTIVE. If no, specify PASSIVE. The default value is ACTIVE.

Desired Available

This field specifies the default desired status of the resource. The desired status of each resource is the goal that automation tries to achieve. The value of the desired status is either AVAILABLE or UNAVAILABLE.

ALWAYS

The desired status of the resource is set to AVAILABLE, unless it is dependent on a resource whose Desired Available is set to ONDEMAND, in which case the dependent resource behaves as if it has a Desired Available setting of ONDEMAND itself.

ONDEMAND

If there is a demand for the resource to be available, its desired status is set to AVAILABLE; otherwise its desired status is set to UNAVAILABLE.

Demand arises either from propagated MakeAvailable votes or implicitly through membership of a non-passive BASIC APG that has a desired status of AVAILABLE. Demand does not arise from dependent resources with a Desired Available setting of ALWAYS.

A MakeAvailable vote that is propagated to the resource overrides any demand considerations.

An active ONDEMAND member of a MOVE or SERVER group always receives a vote that sets its desired status, thus overriding any demand considerations.

ASIS

The desired status is always set to the observed status. It means that the resource remains in its current status and SA z/OS takes no action at any time, as long as there is no request that is placed for or propagated to the resource.

If you leave this field blank, the value inherits from the system defaults (SDF) or sysplex defaults (XDF). If nothing is specified there, the default value is ALWAYS.

Monitor for IPL complete

This field specifies whether (YES or NO) the application group has to be in an AVAILABLE status before IPL is considered to be completed. If nothing is specified, the default value is NO.

Prepare Move

This field specifies whether the downtime during the move or switch of a resource should be kept as short as possible. The prepare move function works only for application groups with behavior set to ACTIVE.

For an application group of nature MOVE, it means that the group member that is currently running will not be stopped until the replacement member is ready to be started, for example, when all parents are available.

To have the highest possible availability, set this value to YES.

If the field is left blank, the value inherits from the system defaults (SDF) or sysplex defaults (XDF).

Move Mode

This field specifies how a move is made from an old member to a new one.

PARALLEL: The new member is started at the same time as the old member is being stopped.
SERIAL: The new member is started after the old member is stopped completely. In this case, not only the start commands but also the prestart processing is delayed until the old member is stopped completely.

If the field is left blank, the value inherits from the system defaults (SDF) or sysplex defaults (XDF), depending on the application group type. If nothing is defined there, the default is PARALLEL.

Status Determination

This field specifies how to determine the application group's compound status.

CSONLY: The worst compound status of any of the group members is used to define the compound status of the application group.

Leave this field blank, if the application group's compound status should be determined from several statuses, like observed status, desired status, automation status, startability status, and others.

Inform List

This field specifies where the application group is registered to, where all status changes are propagated to, and which SMF records are to be written.

Valid values are SDF, EIF, E2E, IOM, ITM, SMF, TTT, USR, and NONE. You can specify one or more values.

If nothing specified here, the value inherits from the system defaults (SDF) or sysplex defaults (XDF). If the application group should not be registered at all, specify NONE to prevent inheritance.

Note: If nothing is specified here and in the default definition, no status changes are propagated. If E2E is specified, the application group will be shown on the E2E domain view. This applies only to application groups that are directly attached to a system or sysplex. For others, the E2E specification is ignored.

Owner

This field specifies whom the operator should contact if there is an error.

Info Link

This field specifies a location (for example, a URL) where additional information about the application group can be found.

Automatically link APL-Resources

This field specifies whether application members should also be automatically linked as resources if the group is linked to another system or sysplex.

NO: Specify NO if you want to disable automatically linking the application members. Otherwise, the automation behavior might not be as expected for complex group definitions (that is, groups with manually adapted preference values or availability targets other than *ALL).
YES: For others, specify YES. The default value is YES.

Note: This field is relevant only to application groups with automation names defined.

The COMMANDS choice on the action bar allows you to either enter commands on the command line using the full command name or fast key symbol (as denoted in parentheses) or select the command from the COMMANDS action bar.

The commands that can be entered are:

CANCEL (C) - Exit without saving changes
ENTER - Verify input
END - Save changes and exit
