Embodiments of the present invention relate to method and apparatus for system problem diagnosis and recovery. According to embodiments of the present invention, problem symptom information in a system can be automatically monitored and collected BY a monitoring apparatus (or referred as to 'agent') deployed at the system side. Upon after receiving such information, the diagnosis apparatus, for example, may automatically determine a root cause of the problem by querying a backend knowledge repository, and possibly generate an executable software package for recovering the problem. If the diagnosis apparatus determines that the currently available information is insufficient to determine a creditable enough root cause and/or is insufficient to generate the software package for recovering the problem, the diagnosis apparatus may interactively control the monitoring apparatus to collect desired additional information. In this way, the efficiency and accuracy of problem diagnosis and recovery may be improved.

It is decided whether to increase a total amount of storage in a pool of Hadoop storage and whether to increase a total amount of processing in a pool of Hadoop processing. If it is decided to increase the total amount of storage and not increase the total amount of processing, the total amount of storage is increased without increasing processing. If it is decided to not increase the total amount of storage and increase the total amount of processing, the total amount of processing is increased without increasing storage. In response to receiving a request to perform a process on a set of data, processing is allocated from the pool of processing and storage is allocated from the pool of storage where the allocated processing and storage are used to perform the process on the set of data.

Genomic application data storage

The present invention increases the efficiency of transmitting data from a plurality of fragmented internet protocol (IP) packets over a computer network. After receiving a plurality of fragmented packets over a computer network interface a computing device may reassemble data from the plurality of packets into an IP packet that includes data from each of the fragmented IP packets. The reassembled IP packet may then be compressed and encrypted before being transmitted to a computer identified in a destination address in each of the plurality of fragmented packets.

Optimizing transfer of fragmented packetized data

Methods are directed towards initializing a path maximum transmission unit value for two gateways in communication via a network tunnel (e.g., VPN environment). The initialized path maximum transmission unit value is used in establishing the network tunnel of the two gateways. Methods are also directed towards synchronizing path maximum transmission unit values for the two gateways after the network tunnel has been established. These methods minimize the occurrence of dropped data packets arising from mismatched path maximum transmission unit value between the gateways.

Method for effective PMTU discovery in VPN environment

Methods and systems are provided for detecting dead tunnels associated with a VPN. An indicator of a tunnel capability, for example, a DPD vendor ID, is received from a peer through a VPN connection. The tunnel capability is associated with one or more phase II tunnels associated with the VPN. Traffic generated by the peer is detected, and if traffic is detected at a tunnel, the tunnel is presumed to be alive. When no traffic is detected in a tunnel, a DPD packet exchange with the tunnel is initiated. A determination is made, based on the packet exchange, whether the tunnel is alive.

Virtual private network dead peer detection

The present disclosure relates to an apparatus, a method, and a non-transitory computer readable storage medium for filtering routing assignment (RA) messages in a computer network. Methods, non-transitory computer readable storage medium, and apparatus consistent with the present disclosure may receive an RA message, extract information included in an RA message when identifying whether that particular RA messages should be forwarded or blocked. Information used to identify when to forward or block particular RA messages may be related to information that identifies a user of a computer or that identifies a computer that sends RA messages over a computer network.

User based stateless IPv6 RA-guard

A data classification system is associated with a hybrid cloud comprising at least one private cloud and at least one public cloud. The data classification system comprises a data set classification model classifying data sets, a cloud classification model classifying the private and public clouds of the hybrid cloud, and mapping policies each specifying a particular mapping between one or more classes of the data set classification model and one or more classes of the cloud classification model. The data classification system classifies a received data set using the data set classification model, and determines for the received data set at least one cloud of the hybrid cloud to which the received data set should be directed for further processing based at least in part on a result of the classification of the received data set, the cloud classification model and a selected one of the mapping policies.

Data classification system for hybrid clouds

The present invention relates to a method and apparatus for data management in multi-tenant distributive environment. According to the embodiments of the present invention, a tenant-specific virtual metadata server may be created and registered with a task manager in a job processing system. The virtual metadata server provides a tenant-specific logical file system namespace. Any access to tenant data will be performed via the virtual metadata server. In other words, such virtual metadata server acts as an interface between a tenant terminal and an entity file system. In this way, it may effectively realize isolation of tenant data and enhance data security. Moreover, by using a virtual metadata server rather than physically isolating user data, the embodiments of the present invention may guarantee the efficiency of data sharing while improving the data security.

Data management in a multi-tenant distributive environment

A data analytics workload is obtained, wherein the data analytics workload includes one or more execution parameters and an input data set. An identifier specific to the data analytics workload is generated. The data analytics workload is at least partially executed based on the one or more execution parameters and the input data set to generate an output data set. Meta data associated with the output data set generated by execution of the data analytics workload is obtained, wherein the meta data includes lineage information corresponding to the output data set generated by execution of the input data set. The meta data is registered in a meta data store.

Lineage information management in data analytics

Information processing techniques for providing collaborative data visualization in a computing system. For example, a method comprises the following steps. A data visualization asset is obtained. The data visualization asset comprises a data component, an execution context component, and a visual asset component, wherein at least one visual asset of the visual asset component is generated from a data set of the data component by execution of at least one process of the execution context component. Collaborative modification of the data visualization asset by at least a portion of a plurality of users is enabled in accordance with a given policy. Information corresponding to the modification of the data visualization asset is tracked.

Collaborative data visualization

Backup data is processed by obtaining a set of metadata associated with backup data. A locality-sensitive hash key is generated for the backup data based at least in part on the set of metadata. The backup data is assigned to one of a plurality of deduplication nodes based at least in part on the locality-sensitive hash key.

Content-aware distributed deduplicating storage system based on locality-sensitive hashing

A resource request is sent from a user to a resource controller. The resource controller is resident on a node of a distributed computing platform comprising a plurality of nodes configured to collectively execute at least one application program. A quota pool associated with the resource controller is searched for a matching resource quota for the user to inherit. The resource quota is assigned to the user when a matching resource quota for the user to inherit is found in the quota pool. The resource request is forwarded to a resource scheduler that globally manages resources for the distributed computing platform, when a matching resource quota for the user to inherit is not found in the quota pool.

Computation resource cyclic utilization

A request is received to perform a process on a set of data. A set of resources, including processing and storage, is obtained to run an appropriate Hadoop system to process the received request. The set of data is processed using the obtained set of resources. One or more storage resources associated with the distributed system are allocated where a total amount of storage associated with the distributed system is independent of a total amount of processing associated with the distributed system. The processing results are stored in the allocated storage resources.
