    摘要: A method, system, and computer usable program product for storing messages in a directory executing in a data processing system are provided in the illustrative embodiments. A message is received over a network and identified in the directory. A base message entry that corresponds to the message is selected in a hierarchy of entries in the directory. A message instance entry for the message is created, such that the message instance entry becomes a child entry of the base message entry in the hierarchy.

    摘要: Illustrative embodiments provide a method for redistributing data in a distributed database. The method provides a set of servers, each of which having a respective portion of the distributed database resident thereon, and for routing requests to the set of servers by means of a proxy server. Responsive to a redistribution request to redistribute the distributed database among the set of servers from a first distribution to a second distribution, setting a flag in the proxy server indicating that redistribution is in progress. Further storing configuration data for the first distribution and the second distribution in the proxy server, and redistributing the data in the distributed database in accordance with the configuration data.

    摘要: A method of hierarchical LDAP wildcard searching in an LDAP directory service having a relational database management system (DBMS) as a backing store. The relational database normally includes a forward index of the character strings in the database. The method begins by generating a reverse index of the character strings in the relational database. Depending on the position of one or more wildcards in the string, the forward index, the reverse index, or both indices, are used to generate the relational database query.

    摘要: A mechanism for providing proxy support for special subtree entries in a directory information tree by defining filters at the proxy level to indicate relationships between main subtree entries and associated special subtree entries. A proxy server receives a request from a client for a special subtree entry and determines whether the distinguished name of the main subtree entry can be built using information in the request and pre-defined relationships between the main subtree entry and the requested subtree entry. If so, the proxy server builds the distinguished name of the main subtree entry associated with the special subtree entry and applies a partitioning filter to the distinguished name of the main subtree entry to determine a target directory server in the plurality of backend directory servers that comprise the special subtree. The proxy server then sends the request to the target directory server.

    摘要: An instruction to delete the entry is received. A second entry that includes a reference to the entry is identified. A third entry including information to be preserved from the entry is added in a deleted entries subtree. The third entry is modified to include the reference information from the second entry. The third entry is saved such that during a restore of the entry the third entry provides the information to restore the entry and the reference to the entry. The third entry may include a set of attributes that store an identifier of the second entry. The entry is restored from the third entry and made available in the directory. A reference is recreated in the second entry to the restored entry forming a restored second entry.

    摘要: A method, system, and computer usable program product for preserving references to deleted directory entries are provided in the illustrative embodiments. An instruction to delete an entry is received. A second entry referencing the entry is identified. The second entry is marked as a ghost reference to the entry. The entry is converted to a deleted entry. A ghost attribute with a value of “false” may be added to the entry. A ghost attribute or tag with a value of “false” may be added to the second entry. The ghost tag may correspond to an attribute of the second entry that references the entry. An entry may be deleted by setting a value of a ghost attribute in the entry to true. The second entry may be marked as the ghost reference by setting a value of a ghost attribute or a ghost tag in the second entry to true.

    摘要: Replicating modifications of a directory that include receiving in a source directory service for a source directory requests for modifications in the source directory and transmitting, from the source directory service to a duplicate directory service for a duplicate directory asynchronously in parallel over a plurality of data communications connections, requests for the same modifications in the duplicate directory. In typical embodiments, a duplicate directory may replicate a subtree of a source directory, receiving requests for modifications may include receiving in the source directory service requests for modifications in the subtree in the source directory, and transmitting requests may include transmitting requests for the same modifications in the subtree in the duplicate directory.
