摘要： Techniques are described for estimating and managing memory compression for query processing. Embodiments of the invention may generally include receiving a query to be executed, ascertaining indicatory data about the retrieved data, and selectively compressing a portion of the data in memory according to the indicatory data. In one embodiment, the amount of compression performed during each query execution is recorded and outputted to assist in adjusting the selective compression process.

摘要： A database query governor determines when a query cannot be executed within a defined time threshold, but still executes the query or some variant of the query so partial results for the query may be returned to the user after executing for less than the defined time threshold, instead of an error message indicating the query was not executed at all. The partial results provide information to the user that may be sufficient for some applications, or may indicate to the user how the query could be modified to run in less time.

摘要： Methods, systems, and products are disclosed for executing a distributed Java application on a plurality of compute nodes. The Java application includes a plurality of jobs distributed among the plurality of compute nodes. The plurality of compute nodes are connected together for data communications through a data communication network.

摘要： A process is disclosed for identifying and recovering from resource leaks on compute nodes of a parallel computing system. A resource monitor stores information about system resources available on a compute node in a clean state. After the compute node runs a job, the resource monitor compares the current resource availability to the clean state. If a resource leak is found, the resource monitor contacts a global resource manger to remove the resource leak.

摘要： Techniques are described for managing query execution using additional performance capabilities from a set of system resources. Embodiments may receive a query and calculate a first estimated execution time for processing the query using a first amount of performance capabilities from a first set of system resources. If embodiments determine that the first estimated execution time exceeds a threshold amount of time, a second estimated execution time is then calculated for processing the query using a second amount of performance capabilities from the first set of system resources. Here, the second amount of performance capabilities is in addition to the first amount of performance capabilities. If the second estimated execution time does not exceed the threshold amount of time, the query is executed using the second amount of performance capabilities from the first set of system resources.

摘要： A relocation mechanism in a multi-nodal computer environment dynamically routes processing units in a distributed computer system based on incoming physical data into the processing unit. The relocation mechanism makes an initial location decision to place a processing unit onto a node in the distributed computer system. The relocation mechanism monitors physical data flowing into a processing unit or node and dynamically relocates the processing unit to another type of node within the ‘cloud’ of nodes based on the type of physical data or pattern of data flowing into the processing unit. The relocation mechanism may use one or more rules with criteria for different data types observed in the data flow to optimize when to relocate the processing units.

摘要： Methods and systems for storing stream data in a stream application are disclosed. The stream application is composed from a plurality of processing elements executing on one or more compute nodes. The plurality of processing elements is communicatively coupled to a management system. The management system is configured to monitor and control operations of the plurality of processing elements. A trigger rule, which includes a trigger condition, is loaded on a selected processing element in the plurality of process elements. The stream data is then monitored at the first processing element to determine if the trigger condition relative to the stream data has occurred. The stream data is stored in a database when the trigger condition occurs. The stream data is stored in the database according to the trigger rule.
