Queues Key

Below the Policy Engine Hub registry key, is the Queues subkey. It contains the following registry values, plus various subkeys, one for each message queue supported by the hub.

ActivePolicyEngines

Type: REG_SZ

Data: Defaults to <localhost>. This specifies a comma-separated list of names or IP addresses of machines hosting policy engines available to the default queue.

AdditionalQueues

Type: REG_SZ

Data: Defaults to null. This specifies a comma-separated list of additional message queues available to the policy engine hub. These queues are in addition to a default queue, which is always available. The example registry architecture diagram shows three additional queues: Small, Medium and Large.

Note: If you edit this registry value while the hub service is running, CA DataMinder automatically creates new registry subkeys for each additional queue. However, if you want to configure your hub in advance, you must manually create a subkey for each additional queue, and you must also add and configure the necessary registry values to this new subkey.

StandbyPolicyEngines

Type: REG_SZ

Data: Specifies a comma-separated list of names or IP addresses of machines, available to the default queue, and which can be used by the hub if an ‘active’ policy engine is unavailable.
