20090234805 | SORTED SEARCH IN A DISTRIBUTED DIRECTORY ENVIRONMENT USING A PROXY SERVER - A mechanism for performing a sorted search in a distributed directory environment using a proxy server. A sorted search request for a set of top entries is sent to each backend server. The proxy server identifies a target server which returned a top entry in the set and sends another sorted search request to the target server for all entries having a sort order higher than or equal to the top entry and a sort order lower than or equal to the next top entry of the set, and returns the entries to a requesting client. The proxy server sends another sorted search request to the target server for a new top entry having a sort order greater than the next top entry and adds the new top entry to the set. The proxy server returns to the evaluating step until no top entries remain in the set. | 09-17-2009 |
20100036952 | LOAD BALANCING USING REPLICATION DELAY - A method, system, and computer usable program product for load balancing using replication delay are provided in the illustrative embodiments. In response to a request to update, a system updates data associated with a write server, forming updated data of a data partition. The system receives a read request for the data partition. The system calculates a time difference between an arrival time of the request to update and an arrival time of the read request. The system receives a set of average replication delays for a set of replica servers serving the data partition. The system directs the read request to a replica server in the set of replica servers whose average replication delay is less than or equal to the time difference. | 02-11-2010 |
20100057697 | VIRTUAL LIST VIEW SUPPORT IN A DISTRIBUTED DIRECTORY - A computer implemented method, data processing system, and computer program product for performing a virtual list view search in a distributed directory environment using a proxy server. The mechanism described in the illustrative embodiments enables a proxy server to provide virtual list view search support in a distributed directory environment when data is partitioned across multiple directory servers | 03-04-2010 |
20100061233 | FLOW CONTROL IN A DISTRIBUTED ENVIRONMENT - A computer implemented method, apparatus, and computer program product for managing requests. Responsive to receiving a request from a client, a determination is made as to whether a connection within a pool of connections has a set of outstanding requests for the client to handle a previous request from the same client. Responsive to a determination that the connection has any outstanding request, a determination is made as to whether a set of requests queued for the connection is equal to or exceeds a threshold. Responsive to a determination that the set of outstanding requests is equal to or exceeds the threshold, subsequent requests from the client are unprocessed until the set of outstanding requests becomes less than the threshold. | 03-11-2010 |
20100241688 | TRANSMITTING INFORMATION ABOUT DISTRIBUTED GROUP MEMBERSHIPS - A method, system, and computer usable program product for transmitting information about dynamic group memberships of an entry stored in a computer memory are provided in the illustrative embodiments. A set of dynamic group filters is received from a server in a distributed data environment. The set of dynamic group filters provides a set of attributes. A determination is made whether the entry includes a subset of the set of attributes. A request for dynamic group memberships of the entry is sent to the server. The request includes the subset of attributes and excludes attributes not used by any of the dynamic group filters. Information about at least one dynamic group of which the entry is a member is received for evaluation. A proxy server may receive the request for dynamic group filters and distribute the request to one or more servers in a distributed data environment. | 09-23-2010 |
20100318541 | Filter Range Bound Paged Search - A filter range based search control to request a range of data from one or more directory servers. A directory server receives a search request from a client application comprising a search filter control defining a set of requested data, a sort control defining a sorting order of the set of requested data, and a range filter control defining a range of entries in the requested data. Data entries matching a search value defined in the search filter control and sorted according to sort attributes defined in the sort control are obtained from a set of directories associated with the directory server to form a sorted list of matching entries. A subset of data entries in the sorted list that match a range value defined in the range filter control are collected, and a response comprising the collected subset of data entries is then sent to the client application. | 12-16-2010 |
20110106822 | Virtual List View Support in a Distributed Directory - A computer implemented method, data processing system, and computer program product for performing a virtual list view search in a distributed directory environment using a proxy server. The mechanism described in the illustrative embodiments enables a proxy server to provide virtual list view search support in a distributed directory environment when data is partitioned across multiple directory servers. | 05-05-2011 |
20120166455 | Filter Range Bound Paged Search - A filter range based search control to request a range of data from one or more directory servers. A directory server receives a search request from a client application comprising a search filter control defining a set of requested data, a sort control defining a sorting order of the set of requested data, and a range filter control defining a range of entries in the requested data. Data entries matching a search value defined in the search filter control and sorted according to sort attributes defined in the sort control are obtained from a set of directories associated with the directory server to form a sorted list of matching entries. A subset of data entries in the sorted list that match a range value defined in the range filter control are collected, and a response comprising the collected subset of data entries is then sent to the client application. | 06-28-2012 |
