RegisterAsRedundantApp

Type

SwitchKit API message

Description

The SK_RegisterAsRedundantApp message is used by the function sk_registerAsRedundant().

If an application needs to register for membership into a Redundant Application Pool (RAP), the application must call the function sk_registerAsRedundant(). The function then uses the SK_RegisterAsRedundantApp message to register the application for membership into a RAP.

To remove an application from a pool, the application calls the function sk_deregisterAsRedundant(), which then also uses the message to take a member out of the pool.

A SK_RegisterAsRedundantAppAck message is an acknowledgment by the LLC, indicating the completion of the original request.

Sent by

Function sk_registerAsRedundant()

Arguments

You can modify the following arguments:

Argument | Description
--- | ---
AppName | AppName is the application name of the requesting application. The name can be obtained by calling sk_getConnectionName().
RedundantAppPoolID | The RedundantAppPoolID is a string that uniquely identifies the class of application wishing to be treated as redundant applications. Notes: RAP IDs are case sensitive.
RedundantAppPriority | RedundantAppPriority is a value indicating the current priority of the application. The higher the value, the more likely it is that the LLC will select the application as primary. Predefined values are: SK_RED_APP_PRI_MONITOR (0) Used by an application wishing to monitor the activity of this RedundantAppClass. An application selecting this priority cannot be considered either primary or secondary. SK_RED_APP_PRI_REMOVED (-1) Used when an application needs to be removed from an RedundantAppClass for which it has previously registered.
DataSize | Size of the data
Data | Data bytes
