A subscriber management system includes at least one Data Directory Server (DDS) located between one or more transaction generators and one or more data servers. The DDS efficiently routes transactions and provides data location functions. The DDS provides high data availability, high on-line transaction rates, batch capabilities, scalability and maintainability. In particular, based upon internal rules within the DDS and the particular transaction type, the DDS routes transactions to the appropriate server(s). Transactions are classified according to where they may be executed. Specifically, transactions may be classified as SPECIFIC, ANY or ALL. A SPECIFIC transaction must be processed at one or more specific servers irrespective of the accompanying arguments. An ANY transaction may be processed at any of the enterprise servers and selection is made randomly. Finally, an ALL transaction requires sequencing through each of the data servers within the enterprise and repetitively performing the transaction.

Method and apparatus for transaction processing in a distributed

A distributed database system for processing a client or customer-site initiated on-line database transaction includes a transaction keying and RF transmitting device and a transaction RF transmission relay device for transmitting the client or customer-site initiated on-line database transaction, a local order RF receiver-convertor for receiving the transaction and converting the transaction to a computer readable format, and a modem for data linking the transaction to a persistent queue, which initiates a database transaction, including information identifying service location equipment and a desired product, and transmits the transaction to the queue. A client message server retrieves the transaction from the queue and transmits the transaction to a data directory server, including a rules database, and the data directory server interrogates at least one of a plurality of dispatch utility servers to identify an available dispatch utility server and routes the transaction to the available dispatch utility server. The available dispatch utility server extracts the information identifying the service location equipment and the product from the transaction, formulates an addressability change remote procedure call (RPC), and transmits the RPC to the data directory server. The data directory server then transmits the RPC to an addressability open server, and the addressability open server identifies the controller, which controls enabling and disabling the desired product, and instructs the controller to update the status of the product.
