Abstract: A data management system or “DMS” provides a wide range of data services to data sources associated with a set of application host servers. The data management system typically comprises one or more regions, with each region having one or more clusters. A given cluster has one or more nodes that share storage. To facilitate the data service, a host driver embedded in an application server connects an application and its data to a cluster. The host driver provides a method and apparatus for capturing real-time data modifications and application state notifications and, in response, generating data transactions in the form of an event journal that is provided to the data management system. The driver functions to translate traditional file/database/block I/O into a continuous, application-aware, output data stream.

Abstract: Computer method and apparatus for connection tree routing in visual modeling of software is disclosed. Tree routing style is represented as a property of a subject connection. A router object manages location of bendpoints of the subject connection in a connection tree. The subject connection maintains an end node as its target instead of a trunk element of the connection tree. The router object is formed of a hierarchy of routers including branch routers, tree routers and forest routers. Different routers maintain different aspects of the tree data forming display of the connection tree.

Abstract: Techniques for performing a multi-level patching operation are described. According to one such technique, before a particular patch is applied, the data containers that are targeted by the particular patch are identified. A determination is made as to whether any of these target data containers already has been targeted by any previously applied patch. A determination also is made as to whether any other data container that contains (immediately or otherwise) any of the target data containers already has been targeted by any previously applied patch. If any target data container or any other data container that contains a target data container already has been targeted by a previously applied patch, then the particular patch is not applied to the target data containers.

Abstract: A method and system for implementing detecting deadlocks in interop-debugging is described herein. One or more synchronization objects that an application program interface (API) could block on are identified. A canary thread that takes one or more of the synchronization objects is created. The canary thread is called to take the one or more synchronization objects. If the canary thread returns within a predetermined timeout period, then the one or more synchronization objects are available and safe to take. If the canary thread does not return within the predetermined timeout period, then the one or more synchronization objects may not be available.

Abstract: A method, system, and architecture for managing computer systems is provided. A management system employs management objects (MOs) to provide administrators the ability to intuitively express the administrative intent in an information technology (IT) environment, and to act out the administrative intent based on the information gathered by the management system. Managed elements of an IT environment, such as, by way of example, hardware components, software applications, software updates, software distribution policies, configurations, settings, etc., may be expressed as MOs. Actions, such as, by way of example, detect, install/apply, remove, remediate, enumerate, etc., may be associated with the MOs. The management system manages the computer systems by deploying the appropriate MOs and their associated actions onto the computer systems, and performing the actions on the computer systems.

Abstract: A code patching device is provided for use with a processor having a read-only memory which stores instruction code and a further memory for storing patch code. A plurality of patch address registers each store an address, in the read-only memory, at which a patch is to be performed. A comparator compares the address of the read-only memory that is being accessed by the processor with the addresses stored in the registers. A control unit selects between code from the read-only memory or patch code from the further memory depending on the comparison. The code patching device can replace, on-the-fly, erroneous lines of code from the read-only memory by corrected ones. During an initialization process the patch code is loaded into the further memory and the registers are loaded with the addresses which require patching.
