摘要： A versioned-data management system is provided with a method for detecting independent changes to a part when an attempt is made to promote a variant of the part. For each variant of a part, there is maintained two identifiers and a flag. The first identifier is the identifier of the last change to that variant. The second identifier is the last-change identifier of the variant which was the source of the drawdown. When the variant is successfully promoted, and there was not previously a variant at the level to which it is promoted, its drawdown-from identifier value is not changed. When the variant is successfully promoted, and there was previously a variant at the level to which it is promoted, the drawdown-from identifier is set to the drawdown-from identifier value of the variant which was previously at the level to which the promote is made. When the promote of a variant fails, the drawdown-from identifier is set to the last-change identifier value of the variant which is first in the search path beginning at the level to which the promote is being made. The flag indicates whether the variant can be promoted by normal means, or must be promoted using promote.sub.-- force. The identifiers and flag are used to identify independent changes and control data integrity in the VDMS at promotion time.

摘要： A method is provided in a versioned database management system for allowing parts to be versioned according to different variant hierarchies, and for maintaining correct configurations of versions of parts as those parts are drawn down, changed, and promoted. Each version of a part is associated with a variant domain. Each variant domain is represented by a single variant hierarchy whose levels can be used to reference versions of parts in that variant domain and controls how versions of parts in that variant domain are drawn down, changed, and promoted. Variant domain default groups are provided so that tools may add new parts without specifying the variant domains to which the parts are to belong. In order to control which versions of parts and from which version domains are visible, variant maps are defined by the user installation. When a change is made for one configuration, it is simultaneously made in any other configuration identified by a variant map which includes the same variant ID. A variant map thus constructed is used by the VDMS to determine the variant hierarchy level to which any instances created belong, and to determine which instances in a promote group are promoted and to which hierarchy level they are promoted.

摘要： A versioned data management system is provided with a method for resolving sources and targets of relationships. For each entity instance, a lifetime ID is recorded. When the add interface is used to add an entity, a value is assigned to the lifetime ID, which value has never been used before for an instance of the entity type. When the update interface is used to update an entity, the lifetime ID is maintained unchanged. If the update results in a new version, the new version is given the same lifetime ID value as that for the version that was the basis for the update. If the delete interface is then used to delete the entity, and the add interface is later used to add an instance with the same part key, that instance will have a different lifetime ID. For each relationship instance, lifetime IDs are recorded for the relationship, its source, and its target. When the add interface is used to add a relationship, a value is assigned to the lifetime ID, which value has never been used before for an instance of the relationship type. Also, the lifetime IDs of the source and target of the relationship are recorded in the relationship instance. The lifetime ID of the relationship and the lifetime IDs of the source and target are maintained unchanged. If an update results in a new version of the relationship, the new version is given the same lifetime ID value as that for the version that was the basis for the update.

摘要： Method and means for operating a computing system for controlling access to and maintaining the integrity of data resources shared by multiple applications executing on a plurality of central electronic complexes (CEC's) while minimizing communication of sharing control parameters between different electronic complexes. Each complex includes a resource lock manager (IRLM) which maintains the hold and wait locks for applications executing under one or more information management subsystems on the complex and selected wait locks for the other complex. Selective communication of lock request information is controlled by hash tables maintained in synchronization in each IRLM, which denote the interest of each complex in each hash class, or congruence class, of data resources. A first complex already having exclusive use of a congruence class grants locks on data resources which map into the congruence class without communication of the request to the other complex. When such communication is required, and the other complex determines that an inconsistent hold lock already exists for the data resource of the request, the lock request is waited in both IRLM's. When the inconsistant hold lock is subsequently released, the wait lock is deleted from the IRLM of the other complex, and the first complex grants the requested lock.Each IRLM also includes an identified subsystem list (ISL), which is maintained in synchronization and used along with the hash tables and hold/wait locks to retain locks across CEC, subsystem, and communication link failures and to enhance recovery thereafter.
