Abstract: A method of removing metadata from a database in a multimode replication system includes establishing a metadata retention period for nodes in the system as well as associating changes with nodes on the system. The system responds to an expiration of the retention period for any one node by analyzing the associated changes and nodes and determining if the change affects data shared with other nodes. If the data is shared with other nodes then the expired retention period node metadata is removed from the system. If the expired metadata retention period node does not share the changes with other nodes, the metadata is not removed. This allows any unique changes to still be entered into the database without adversely affecting other nodes.

Abstract: A method of synchronization for use in a distributed data processing system comprising a legacy computer having means for storing a master version of data, an application server, and a thin client computer which stores a copy of the master version of data. Firstly, the thin client executes operations locally on the copy. The operations are sent in a list to the application server. The application server executes the operations on the master data, on behalf of the thin client. If the operations can be executed successfully on the master version, synchronization occurs in that the successful operations are applied to the master version.

Abstract: A cluster recovery process is implemented across a set of distributed archives, where each individual archive is a storage cluster of preferably symmetric nodes. Each node of a cluster typically executes an instance of an application that provides object-based storage of fixed content data and associated metadata. According to the storage method, an association or “link” between a first cluster and a second cluster is first established to facilitate replication. The first cluster is sometimes referred to as a “primary” whereas the “second” cluster is sometimes referred to as a “replica.” Once the link is made, the first cluster's fixed content data and metadata are then replicated from the first cluster to the second cluster, preferably in a continuous manner. Upon a failure of the first cluster, however, a failover operation occurs, and clients of the first cluster are redirected to the second cluster.

Abstract: A method for performing multiple merge operations with a source data structure and a plurality of destination data structures, in which the source data structure is scanned one time in order to obtain source data that is then used for multiple merge operations. The source data is then used consecutively in order to merge the source data into the one or more destination data structures. Each merge is performed using the same scan of the source data structure and within the same execution of a database command.

Abstract: Splitting and merging database object information sharing streams. Streams are also referred to herein as “propagations”. Splitting and merging information sharing streams can be used to improve performance in a information sharing environment when a failed or slow DBS impacts the performance. In one embodiment, an auto split process monitors the progress of applying changes at each node and detects the presence of a failed or a slow node. Once the failed or slow node is identified, the auto split process splits the propagation such that the offending node is sent through a separate propagation. Furthermore, an auto merge process can be started to monitor the newly created separate propagation. At a later point, the new propagation can be merged back into the original stream. For example, if the offending node catches up with other nodes, the auto merge process merges the newly created propagation back to the original propagation.

Abstract: Techniques are described for sharing multidimensional data between software systems, such as enterprise software systems. Specifically, the techniques provide mechanisms for defining inter-application “links” for automatically moving data among different databases associated with the enterprise software systems. For example, a system may include a first database storing multidimensional data for a first software application, and a second database storing multidimensional data for a second software application. The system further includes an interface by which an administrator defines a link that specifies a source area of the first database and a target area of the second database. A link control module automatically moves multidimensional data from the source area to the target area in accordance with the link. The link control module may automatically move the multidimensional data directly between live portions of the respective databases.

Abstract: A system for synchronizing account names from a plurality of source security systems. In response to coupling a conversion system between the plurality of source security systems and a target security system, identity data from a human resource system and account data from the plurality of local source security systems is loaded into the conversion system. A name resolution rule set is retrieved and a unique account name identification is generated for a set of account names associated with an identity using the name resolution rule set. The set of account names associated with the identity is converted to the unique account name identification to produce a synchronized set of account names associated with the identity. Then, the synchronized set of account names associated with the identity is stored in the target security system.

Abstract: Methods, techniques, and systems for providing replication mechanisms in distributed computer environments executing database applications are provided. The mechanisms provide for replication of application objects between clients in the distributed computer environment as well as between an application server and a database server in the distributed computer environment, wherein the copying of an object onto a target storage at a client or a server is performed not before a request on that object is initiated via the target storage. In an example embodiment, each application object has assigned a proxy object, which sits before the real object. Accordingly, the proxies take over functions of lazy loading and change tracking from real application objects. Objects which have been loaded into the target context are stored in a local object store at the respective client or server.

Abstract: While consulting indexes to conduct a search, a determination is made from time to time as to whether it is more efficient to consult individual indexes in a set or to merge the indexes and consult the merged index. The cost of merging indexes is compared with the cost of individually querying indexes. In accordance with the result of this comparison, the indexes are merged and the merged index is consulted, or the indexes are individually consulted. A cost-balance invariant in the form of an inequality is used to equate the cost of merging indexes to a weighted cost of individually querying indexes. As query events are received, the costs are updated. As long as the cost-balance invariant is not violated, indexes are merged and the merged index is queried. If the cost-balance invariant is violated, indexes are not merged, and the indexes are individually queried.

Abstract: A method for optimizing the cost of searches through a multimedia repository is disclosed where the repository contains a plurality of objects having at least two different attributes such as color in a newspaper photograph and text in the subtitle. The method comprises selecting a ranking expression, translating the ranking expression into resulting filter conditions and then optimizing the resulting filter conditions to perform the search. A database look-up step is included which determines the cost of performing searches over the various subconditions of the filter condition. The least costly subcondition is searched first to retrieve objects from the multimedia repository. The remaining subconditions are then evaluated on the retrieved objects using either a search step or probe step depending upon the determined cost to perform each. A further database look-up step predicts a grade of match necessary in the translated ranking expression to retrieve at least the number of objects requested in the search.
