20100250225 | DATE AND TIME SIMULATION FOR TIME-SENSITIVE APPLICATIONS - A process for providing a simulated date and/or time to a time-sensitive application is disclosed herein. Such a process may include detecting the invocation of a time handler method configured to retrieve system time. Upon detecting the invocation, the contents of a call stack may be captured and analyzed to determine which requester method initiated the invocation. The process may then determine whether the requester method should receive a real or simulated system time. A real system time may be returned to the requester method in the event it should receive the real system time. A simulated system time may be returned to the requester method in the event it should receive the simulated system time. A corresponding apparatus and computer program product are also disclosed and claimed herein. | 09-30-2010 |

20130139167 | Identification of Thread Progress Information - Embodiments relate to a method, apparatus and program product and for capturing thread specific state timing information. The method includes associating a time field and a time valid field to a thread data structure and setting a current time state by determining a previous time state and updating it according to a previously identified method for setting time states. The method further includes determining status of a time valid bit to see if it is set to valid or invalid. When the status is valid, it is made available for reporting. | 05-30-2013 |
20140344314 | OPTIMIZING STORAGE IN A PUBLISH / SUBSCRIBE ENVIRONMENT - Creating message files in a publication subscription computer system by: (i) receiving data corresponding to a first message; (ii) receiving a list of subscribers that subscribe to a topic of the first message; and (iii) creating a digital data file that includes a payload data and a consumption metadata. The payload data includes content data corresponding to the first message. The consumption metadata includes data relating to whether one or more subscribers of the list of subscribers will potentially consume the first message at a later period in time from the time of receiving the content data corresponding to the first message. | 11-20-2014 |
20150121352 | IDENTIFICATION OF CODE SYNCHRONIZATION POINTS - An illustrative embodiment of a computer-implemented method for identification of code synchronization points collects locking data for a set of locks in a managed runtime environment associated with the processor to form a set of contended metrics and analyzes the set of contended metrics using a set of predetermined event triggers. The method further determines whether a threshold in a set of predetermined thresholds in the set of predetermined event triggers is met and identifies a particular form of call path capture for a lock associated with the predetermined event trigger identified as having met the predetermined threshold. Call path information for the lock is captured using the particular form of call path capture. | 04-30-2015 |
