The method provides for a way to ensure that the application program running on the host computer handles data received from the at least one mobile computer terminals when one of the mobile computer terminals goes out of range of the wireless network. Communication and association may be established between a mobile computer terminal and an access point on a local network. Then, when it has been determined that communications between the mobile computer terminal and the access point have been impeded, the mobile computer terminal may switch to batch mode to continue data collection.

In one embodiment of a method and apparatus for protecting data, voice, and video networks from individuals with malicious intent, a real network or network device has a vicarious simulated counterpart that may take the place of the real device or network upon appropriate triggering. The simulated counterpart behaves like the real device, but records the suspect transactions. The integrity of the real network or device is therefore continuously maintained because the suspect is isolated from the real network and the suspect transactions are not passed on to the actual device or network. The recorded transactions may then be analyzed for purposes of exposing the perpetrator, discovering perpetrator behavior patterns, and identifying device or network security weaknesses.

The loss of data stored in a secure memory card, such as a SIM card, due to the physical destruction thereof is prevented. A host unit performs card authentication of a memory card, and transmits update data for the memory card by security communication to update data when the result of the authentication is OK. Then, the host unit outputs a request for mirror-updating the card data to a base station server. When an access is permitted, the card data is transmitted to the base station server via the host unit to mirror-update the card data. When the mirror-updating of the card data is completed, the base station server returns a completion confirmation to the host unit, so that a data backup process is completed. By thus causing the base station server to mirror-update the data in the memory card, the loss of the stored data is prevented.

To provide a communication apparatus for achieving further improvements in communication quality and power saving effect, without depending on network environments. A portable terminal (211) as a communication apparatus includes: a communication I/F unit (108) performing data transmission/reception with a transmitter apparatus (203) on a communication protocol having flow control such as TCP; a power control unit (106) switching power on and off to the communication I/F unit (108); and a suppression/resumption control unit (104) determining cycle interval Tc and cycle data size Dc according to communication quality required by a communication application program and, per cycle interval Tc, causing data of cycle data size Dc to be transmitted in a burst state, suppressing data transmission from the transmitter apparatus (203), and causing the power control unit (106) to power off the communication I/F unit (108) while the data transmission is suppressed (T2 to T3), using the flow control mechanism.

A method and system within a data processing system for predicting failure of a hard disk drive having a fluid bearing during runtime operation of said hard disk drive, wherein said fluid bearing has an established signature dynamic fluid response. First, a runtime vibration level of the fluid bearing is measured. This runtime vibration level is then translated into a runtime dynamic fluid response which provides an indication of the operating condition of the fluid bearing. The runtime dynamic fluid response is compared with the baseline dynamic fluid response in real-time during operation of the hard disk drive. Finally, in response to a predetermined departure of the runtime dynamic fluid response from the baseline dynamic fluid response, a protective response is initiated, such that data loss within the data storage system due to fluid bearing failure is prevented.

An apparatus, system, and method are provided for verified fencing of a rogue node within a cluster. The apparatus may include an identification module, a shutdown module, and a confirmation module. The identification module detects a cluster partition and identifies a rogue node with a cluster. The shutdown module sends a shutdown message to the rogue node using a message repository shared by the rogue node and the cluster. The shutdown message may optionally permit the rogue node to preserve latent I/O data prior to shutting down. The confirmation module receives a shutdown ACK from the rogue node 206. Preferably, the shutdown ACK is sent just prior to the rogue node actually shutting down.

A remote copy technique according to which data of a primary volume is migrated while continuing remote copy processing and receiving access requests from a host. A remote copy system comprises a first storage system having a first primary volume, a second storage system having a second primary volume and a third storage system having a secondary volume, and remote copying is performed between the first primary volume and the second volume. When data in the first primary volume is migrated to the second primary volume, an access request from the host to the primary volume is transferred to the second primary volume. Further, the second storage system stores write data received from the host and data of the first primary volume received from the storage system, into the second primary volume. Out of data stored in the second primary volume, the second storage system sends data determined by management information received from the first storage system, to the third storage system.

Volatile memory is placed into a data-preserving safe state in a computer system in response to any one of a reduction in power applied to the volatile memory, a bus reset signal on a data communication bus of the computer system, and an absence of a bus clock signal on the bus. The volatile memory is powered from an auxiliary uninterruptible power supply in response to the reduction in power. The volatile memory is also placed into the data-preserving safe state in response to a cessation in executing software instructions by a CPU of the computer system. Placing the volatile memory into the safe state in response to and under these conditions enhances the opportunity to preserve data in response to error and malfunction conditions.
