Abstract: A system and computer program product for performing failover in a redundancy group, where the redundancy group comprises a plurality of routers including an active router and a standby router, the failover being characterized by zero black hole or significantly reduced black hole conditions versus a conventional failover system. The system comprises a processing unit connected to the memory and adapted to execute the plurality of instructions, which cause an information appliance to: receive an incoming message at a switch; send a request of identification to the plurality of routers to identify a current active router, where the current active router represents a virtual router of the redundancy group; and in response to receiving a reply containing an identification from the current active router within a predetermined time, forward the incoming message to the current active router.

Abstract: Providing efficient data replication for a transaction processing server is provided. A notification is received from the transaction processing server which completes a transaction of a message. The notification includes a message digest and a message identifier. The message identifier in the received notification is compared with a stored message identifier. In response to a match of the comparing of the message identifier, the message digest in the received notification is compared with a stored message digest. In response to a match of the comparing of the message digest, a stored input message is directly stored in a physical storage.

Abstract: A method executes a preempt by a standby database appliance in a high-availability active/active appliance cluster. The appliance cluster includes a transaction processing standby group and a persistent storing standby group. The transaction processing standby group includes a primary active appliance and a standby appliance. One or more processors receive a Hello message from the primary DB appliance. The processor(s) examine a priority field in the Hello message, in order to determine a priority of the standby database appliance according to the persistent state to thereby determine whether the standby database appliance requests a preempt, where the persistent state includes a state of an application and a database of the primary DB appliance. The processor(s) implement a failover in response to the preempt request to thereby take over a duty of the primary DB appliance.

Abstract: A method routes data to an appliance in a high-availability active/active appliance cluster. Messages received by appliances are assigned by a self-balancing module to balance a load of appliances in the appliance cluster, which includes a persistent storing standby group and a transaction processing standby group. Persistent storing data, which is generated by processing the messages, are stored in a virtual persistent storage, which provides an interface between a persistent storage of a primary database appliance and an application for processing the messages. The virtual persistent storage is linked to the persistent storage of the primary database appliance in response to an appliance that receives the messages not being the primary database appliance, thereby sending persistent storing data to the persistent storage of the primary database appliance.
