Abstract: A system and method dynamically transitions the file system role of compute nodes in a distributed clustered file system for an object that includes an embedded compute engine (a storlet). Embodiments of the invention overcome prior art problems of a storlet in a distributed storage system with a storlet engine having a dynamic role module which dynamically assigns or changes a file system role served by the node to a role which is more optimally suited for a computation operation in the storlet. The role assignment is made based on a classification of the computation operation and the appropriate filesystem role that matches computation operation. For example, a role could be assigned which helps reduce storage needs, communication resources, etc.

The method also includes swapping data usage statistics for the data stored to the first location with data usage statistics for data stored to the second location in response to a determination that data usage of the data stored to the second location is not accounted for in the data usage statistics for the data stored in the first location after a first portion of the data stored to the first location is swapped with a second portion of the data stored to the second location. Moreover, data blocks which are swapped within a same extent do not have data usage statistics thereof swapped.

The method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable to determine that a first site is waiting for a first object locked by a second site. The programming instructions are further operable to determine that a third site is waiting for a second object locked by the first site, and to send a first probe to the second site to determine whether the second site is waiting. A second probe is received and indicates that a site is waiting for an object locked by the first site. The second probe further indicates a deadlock in a distributed server environment to be resolved.

Abstract: An approach is provided that registers a wearable device in response to receiving a registration request that includes a set of acceptable user states and a corresponding set of acceptable times to perform a set of actions. When the approach receives a request from the user of the network-accessible site to perform a selected one of the set of actions, the approach transmits an inquiry to the wearable device registered to the user. Then, the approach receives a current state of the user from the wearable device responding to the transmitted state inquiry and determines a current time. In turn, the approach performs the selected action at the network-accessible site in response to determining that the received current state of the user matches one of the set of acceptable states and the current time matches one of the set of acceptable times.

During a handshake protocol when establishing a secure session, at least two sets of cipher suites are transmitted to a server by a client. A choice cipher suite for each set of the at least two sets of cipher suites are received by the client from the server. The client selects a first choice cipher suite from among the choice cipher suites received from the server. The client establishes a connection with the server using the first choice cipher suite to encrypt the connection.

Abstract: A mechanism is provided in a data processing system for de-duplication aware secure delete. Responsive to receiving a secure delete request for a file, the mechanism identifies a list of file blocks to be securely deleted from a physical disk device. Responsive to determining at least one virtual block of another file refers to a given disk block corresponding to a file block in the list, the mechanism copies the given disk block to generate a copied disk block in the physical disk device and updates a pointer of the at least one virtual block to refer to the copied disk block. The mechanism writes a secure delete pattern for each file block in the list of file blocks to a disk block in the physical disk device without performing de-duplication processing.

Abstract: A first quality of service (QoS) desired for a first application during a period over a wireless network is determined. From a plurality of data communication channels, a data communication channel presently assigned to a first type of data packets is identified, the first type of data packets being used by the first application. A determination is made that the presently assigned data communication channel is unsuitable to provide the first QoS. A ranking of the first type of data packets is adjusted relative to a second type of data packets to assign a new rank to the first type of data packets. The new rank is transmitted to a service provider system associated with the wireless network, the new rank causing the service provider system to assign the first type of data packets to a second data communication channel in the plurality of data communication channels.
