    • A new method and framework for re-partitioning directory servers supporting user services in a site that receives access requests from users. According to the present invention, a management server transfers groups of directory objects from original directory servers to newly added directory servers without service interruption to users of the site. The directory objects are stored in categorical groups such that the directory objects in each group share an attribute. According to the present invention, certain groups in the original directory servers are identified for migration to the newly added servers based on a load-balancing scheme. In one embodiment, the identified groups are marked for migration to limit access to the directory objects therein. After successfully being migration, the groups are unmarked and access is resumed. In another embodiment, the management server includes a table storing location information that is updated to indicate successful transfer of the identified group of directory objects from the original server to the newly added server.
    • 一种用于重新分配目录服务器的新方法和框架,支持在用户接收访问请求的站点中的用户服务。 根据本发明,管理服务器将目录对象的组从原始目录服务器传送到新添加的目录服务器,而不会对站点的用户造成中断。 目录对象存储在分类组中,使得每个组中的目录对象共享一个属性。 根据本发明,基于负载平衡方案,识别原始目录服务器中的某些组用于迁移到新添加的服务器。 在一个实施例中,标识的组被标记为用于迁移,以限制对其中的目录对象的访问。 成功迁移后,组将被取消标记,并且恢复访问。 在另一个实施例中,管理服务器包括存储位置信息的表,其被更新以指示所识别的目录对象组从原始服务器到新添加的服务器的成功传送。
