International Classification:

G06F 1700

US Classification:

707103Y, 709220

Abstract:

Innovative managers of persistent data are provided. As an example, in a client/server environment, a persistent manager object may be initialized on both the client and server subsystems. The persistent manager objects may be instances of the same persistent manager class. The persistent manager object on the client subsystem may receive a request to store persistent data and the persistent manager object on the client sends the request to the persistent manager object on the server subsystem. The persistent manager object on the server subsystem may then store the persistent data to make it subsequently be available for the client subsystem.

International Classification:

B24B 1/00

US Classification:

451 57, 451 59, 451398

Abstract:

A retaining ring can be shaped by machining or lapping the bottom surface of the ring to form a shaped profile in the bottom surface. The bottom surface of the retaining ring can include flat, sloped and curved portions. The lapping can be performed using a machine that dedicated for use in lapping the bottom surface of retaining rings. During the lapping the ring can be permitted to rotate freely about an axis of the ring. The bottom surface of the retaining ring can have curved or flat portions.

Inventors:

Bernard A. Traversat - San Francisco CA
Tom Saulpaugh - San Jose CA
Jeffrey A. Schmidt - Boulder Creek CA
Gregory L. Slaughter - Palo Alto CA

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 1500

US Classification:

707100

Abstract:

A method and system are disclosed for updating and managing a configuration database used to store configuration and user data in a computer network having multiple clients, such as network computers. The transaction management mechanisms described determine whether new data, such as a new user or specific property, is being added to the configuration database or whether an existing node in the database is being modified by a transaction. A locking mechanism obtains a lock on a node according to whether a new node is being added to the configuration database or an existing node is being modified. During this process, an identifier is assigned to the transaction that caused the lock that acts as a transaction handle. The transaction then proceeds to modify the configuration database by either adding new data or modifying existing data. The locking mechanism then commits the transaction by releasing the lock if the modification or insertion is successful, or aborts the transaction if the modification or insertion fails.

International Classification:

G06F 1516

US Classification:

709203

Abstract:

Methods and apparatus are disclosed for providing a data framework and associated client/server protocol for storing and exchanging data among computers in a network. A data schema having an n-way tree-type structure with a root node layer, intermediate node layers, and a data layer for storing configuration data is described. The intermediate node layers contain a multitude of nodes containing categorical information relating to components and various aspects of the computer network. Following a tree structure, each intermediate node and root node has branches emanating to nodes below it. These subordinate nodes are referred to as children nodes. The data node layer is at the bottom of the tree and contains actual specific configuration data relating to components and other aspects of the computer network, such as information regarding users registered to use the network. Certain portions of the intermediate nodes and data nodes make up persistent dataspaces in which the actual specific configuration data in the data nodes is modified on either a client or a server computer, and is stored on the server computer. This allows the associated specific information to be nonvolatile and accessible by a multiplicity of client computers.

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 1730

US Classification:

707202

Abstract:

A method and system for creating and maintaining a journal of transactions directed to a configuration database is disclosed. A multi-threaded journaling method logs transactions in a configuration database by first receiving a database transaction, the transaction being either a single modification, e. g. insertion, deletion, update, or a series of modifications directed to the configuration database. An initial entry is inserted into a journal file where the initial entry includes a transaction identifier or handle that corresponds to the database transaction. Subsequent entries are inserted into the journal file corresponding to the specific updates of the transaction, the subsequent entry containing the transaction identifier and actual transaction data relating to the specific update. The journaling mechanism then determines whether each of the specific updates to the configuration database has been successfully completed. A final entry for the transaction is inserted based on the determination of whether each of the specific updates was successfully completed.
