  • Publication number: 20160050296
    Abstract: Batch compression management of messages. A message being sent to a batch for transmission is intercepted. The message is assigned to a batch pool, in which multiple batch pools are provided as sub-sets of the batch. The assigning of the message to the batch pool is based on a similarity of properties of the message with other messages and determined by looking up the properties in a batch pool mapping database. The message is added to the batch pool or a new batch pool is created for the message. A batch pool of messages is compressed using a dictionary of the properties common to at least some of the messages in the batch pool. The compressed batch pools are transmitted over an input/output channel.

  • Patent number: 9264310
    Abstract: A method for event processing within a complex event processing environment. The method includes monitoring a plurality of event processing paths of the complex event processing environment. The method includes determining that utilization of server resources in the complex event processing environment has exceeded a threshold value and identifying one or more event processing paths responsible for the high utilization of server resources. The method includes determining that the one or more event processing paths contain an independent rule, wherein an independent rule includes a rule or a rule subset where data for processing of the rule or rule subset is accessible by a client computing device. The method then includes determining the client computing device can perform processing of the independent rule and transferring processing of the independent rule to the client computing device.

  • Patent number: 9244813
    Abstract: Software is traced using Extensible Markup Language (XML) messages. A trace command, which includes one or more specified fields to be traced and a trace output file location, is defined. A determination is made as to whether the trace command is for a full trace or a differential trace, where the full trace traces all the one or more specified fields, and the differential trace traces specified fields only in response to the specified fields having a value that has changed during processing. The trace command is added to an XML input message for propagation through one or more products. Trace data is collected from the full trace or the differential trace for defined fields at each product, and then stored at the trace output file location.

  • Publication number: 20150378757
    Abstract: A method of optimizing software source code, where the source code is for execution as compiled bytecode using a just-in-time compiler. The source code is compiled to generate corresponding compiled bytecode. The bytecode is then executed using a just-in-time compiler. Run-time optimization actions performed by the just-in-time compiler during execution of the bytecode are determined, and analysed to determine corresponding optimization data for the source code.

  • Publication number: 20150163122
    Abstract: A messaging system comprises a plurality of connected components and including a schema defining fields for messages, at least one field defined as non-essential. A mechanism for operating the messaging system comprises the steps of collecting one or more performance metrics for one or more components of the messaging system, determining that at least one performance metric has crossed a predetermined threshold, informing one or more components of the messaging system that a surge in workload has occurred, and the informed components removing non-essential fields from transmitted messages and/or not processing non-essential fields from received messages.

  • Patent number: 8924932
    Abstract: A computer accesses a stack data and a source code of a program. The computer searches for a first change made to the program, wherein the first change is one of a change to a method of the program, a change to a class of the program, a change to a method that is invoked by the program, or a change to a class containing a method that is invoked by the program. The computer identifies the first change that was made to the program and determines the probability that the identified first change caused one or both of an error and a regression. The computer generates a ranked list of identified changes based, at least in part, on the probability that the identified first change caused one or both of an error and a regression.

  • Publication number: 20140366032
    Abstract: Event processing is prioritized based on system workload. A time constraint attribute is defined in an event rule. The event rule uses one or more events. An event processing system is monitored to determine when the system is under a predefined level of stress. If the system is determined to be under the predefined level of stress, the time constraint attribute in the event rule is used to establish when the processing of a received event used in an event rule must be carried out.

  • Publication number: 20140310694
    Abstract: A computer captures a thread state data of a first program. The computer generates a second program by applying a first program patch to the first program. The computer inserts additional code into a source code of the second program. The computer executes a first performance test using the second program and the inserted additional code. The computer monitors a first status of the second program and the inserted additional code that are under the first performance test. The computer determines a degree that a first deadlock state was prevented during the first performance test. The computer generates a first message based, at least in part, on the determined degree that the first deadlock state was prevented during the first performance test.

  • Publication number: 20140129584
    Abstract: A method, system, and/or computer program product handles a query generated by a user of one of multiple local network devices that are coupled to a network. Multiple system queries are autonomously issued, by a computer that is coupled to the network, requesting states of the local network devices. Query statements, responsive to the system queries and being sent to a wide area network search engine, are intercepted. A natural language query, which is a logical query that is answered by one of the multiple query statements, is generated from one of the multiple query statements. An unstructured query, from a user, about a state of a particular device is received. The unstructured query from the user is compared with the natural language query in order to determine if a match between the query from the user with the natural language query exceeds a predetermined threshold value.

  • Publication number: 20140123149
    Abstract: Disclosed is a method for selecting one of a plurality of versions of a software component of a message queuing software product to perform a task. One or more rules describing one or more characteristics of the plurality of versions of the software component is provided. Responsive to a determination that the rule applies to the task to be performed: a list of the plurality of versions of the message queuing software product is obtained, it is checked whether the software component of the one of the plurality of versions of the message queuing software product is available for use; and the most preferred version of the message queuing software component available is used to perform the task. Responsive to a determination that none of the rules apply to the task to be performed, the task is performed with the most preferred version of the message queuing software component.

  • Publication number: 20140078876
    Abstract: Embodiments relate to controlling persisting of data to disk for use with a messaging system including an application operable for generating and sending a message to a destination. An aspect is an apparatus, which includes a comparator operable to determine whether the message includes common data, and an extractor, responsive to a determination that the message includes common data, configured to extract the common data and non-common data from the message. The apparatus also includes a persistor operable to determine whether the common data have already been persisted to disk. The persistor is operable, in response to a determination that the common data have not already been persisted to disk, to separately persist the common data and the non-common data to disk. The persistor is operable, in response to a determination that the common data have already been persisted to disk, to persist the non-common data to disk.
