| ### Managing GDS GDS provides the following functions for management tasks: · Administrative Functions This directory management function, which is available after logging into a DSA, supports administration of the contents of the GDS database, both local and remote. You can choose from the four types of administration functions in the following list. These administration functions allow you to administer objects, shadows, trees, and schema for your directory service system. A GDS schema is a set of rules and constraints for tree structure, object class definitions, attribute types, and syntaxes that characterize the Directory Information Tree (DIT). - Object Administration This function controls objects and changes their attributes. - Schema Administration This function modifies the Object Class Table, Structure Rule Table, and Attribute Table to store a new schema in the Directory System Agent. - Shadow Administration This function executes, schedules, or modifies shadow jobs for updating. - Tree Administration This function adds, deletes, or modifies subtrees. · Administrative Functions Under the DUA Cache This directory management function supports the administration of the contents of the local DUA cache database. You can choose from the two types of administration functions in the following list. These administration functions allow you to administer the objects stored in the local DUA cache database and the cache update job. - Object Administration This function controls objects stored in the local DUA cache database and changes their attributes. - Cache Update This function displays, activates, or deactivates the Cache Update job, or changes its update frequency. · Activation of a directory system installation This directory management function activates the directory installation by starting the background processes of GDS. · Deactivation of a directory system installation This directory management function ends the background processes of GDS. All running directory processes are ended, but running operations are not interrupted, and the data consistency of the managed data is retained. For more information on these directory management functions, see the OSF DCE GDS Administration Guide and Reference. ###
