Abstract: Systems and methods are provided that allow client programs using APIs for accessing local DB2 databases to access DB2 systems on remote logical partitions and remote zSeries mainframes rather than from a local DB2 system. For example, a method may include intercepting a DB2 request using a documented API for accessing local DB2 databases from a client program executing on a source mainframe system. The method may also include selecting a destination mainframe system and sending a buffer including information from the request from the source mainframe system to the destination mainframe system and establishing, at the destination mainframe system, a DB2 connection with the DB2 system from the request. The method may further include receiving a response from the DB2 system, sending a buffer having information from the response from the destination mainframe system to the source mainframe system, and providing the information to the client program.

Abstract: A method to efficiently create a consistent image of a database index at any point-in-time by reversing the effect of uncommitted updates by applying database transaction logs to an index page set in a single pass. The created image can be used to recover the database index to a point in time that is consistent with its associated table, or for physical migration where data and indexes are migrated to another database that may or may not be on the same DBMS and the indexes and data must be consistent as of the same point in time.

Abstract: Techniques are described to allow the deprecation of classes in an object-oriented data model, such as a CDM for a CMDB. When a class is deprecated and replaced by another existing or new class, data associated with instances of the deprecated class may be migrated to the replacement class. A mapping between the deprecated class and its replacement class may be provided to allow existing applications to continue to access data using the deprecated class without change until the deprecated class is finally deleted or the application is updated to use the replacement class. New applications written to use the object-oriented data model after the deprecation may use the replacement class to access data instances created using the original data model.

Illustrative “resources” include, but are not limited to, computer systems, components of computer systems, data storage systems, switches, routers, memory, software applications (e.g., accounting and database applications), operating systems and business services (e.g., order entry or change management and tracking services).

Abstract: Systems and methods are provided for reorganizing a partition-by-growth database with LOB columns. An example method includes creating a partition assignment table by performing a logical reorganization of the partition-by-growth database, wherein an assignment of at least one base table row and its corresponding LOB in the partition assignment table differs from a current assignment of the at least one base table row. The method also includes performing a base table reorganization based on the partition assignment table in parallel with a LOB auxiliary table reorganization based on the partition assignment table and a LOB dataset assignment table. The method may also include applying changes to the reorganized base tables and the reorganized LOB auxiliary tables using the partition assignment table.

Abstract: Systems and methods are provided that intercept access to mainframe computing systems' messaging systems. For example, a method may include using a replacement messaging interface adapter to intercept a messaging request being directed from a client program to a messaging interface module of a messaging subsystem that is identified by a messaging stub interface module that implements a documented messaging interface. The method may also include performing an auxiliary function on the messaging request. The method may additionally include transmitting the messaging request to the messaging interface module of the messaging subsystem. The method may further include receiving a response from the messaging subsystem. Additionally, the method may include providing the response to the client program.

Abstract: A generic discovery methodology collects data pertaining to components of a computer network using various discovery technologies. From the collected data, the methodology identifies, filters and analyzes information related to inter-component communications. Using the communication and application information, the methodology determines reliable relationships for those components having sufficient information available. To qualify more components, the methodology implements a decision service to generate hypothetical relationships between components that are known and components that are unqualified or unknown. The hypothetical relationships are presented to a user for selection, and each hypothetical relationship is preferably associated with an indication of its reliability.

Abstract: A graphical representation of a service model provides a full view of a portion of the graphical representation. A sub graph view may be displayed for nodes of the graphical representation of the service model that are associated with a selected node, including nodes that may not be visible in the full view. The sub graph view may be interactive, providing additional information regarding the nodes displayed in the sub graph view, and allowing making nodes in the sub graph view visible or invisible in the full view. Information may be displayed in the sub graph view about the status of the components being modeled by the service model corresponding to nodes displayed in the sub graph view.

Abstract: Detection of anomalous events in the operation of information technology (IT) components includes receiving messages, which describe events in the operation of the IT components in real time, and categorizing and condensing the messages received in a first time interval into message patterns by message pattern type. Based on a distribution of occurrences of the message patterns in the first time interval and in preceding time intervals, anomaly scores are assigned to the message patterns, and one or more of the message patterns are classified as being anomalous message patterns that correspond to potentially anomalous events in the operation of the IT infrastructure installation. A degree of correlation between occurrences of the anomalous message patterns and occurrences of application alarms is determined. Message patterns with high anomaly scores and having a high degree of correlation with application alarms are deemed significant and prioritized for display to users.

Abstract: Overlay datasets provide an efficient, flexible and scalable mechanism to represent the logical replication of one or more prior defined datasets. Only changes made to an entity in an overlay dataset's underlying dataset are replicated into the overlay dataset (such changes do not affect the underlying dataset). Read operations directed to the overlay dataset will find entities in the overlay dataset if they exist and in the underlying dataset(s) if no overlay-specific entity exists. Accordingly, overlay datasets provide an efficient mechanism for making changes to an existing dataset without suffering the high processing time and storage overhead associated with prior art copying and versioning techniques. Overlay datasets also provide a natural mechanism to keep two or more datasets in synchronization because changes to a base or underlying dataset's entities are “visible” in its associated overlay dataset (unless the entity has been modified in the overlay dataset).
