摘要:
A latch apparatus is configured to latch an actuator arm assembly that can position a read/write head relative to a data storage disk in a disk drive. The latch apparatus includes a latch arm, a coil, a permanent magnet, and a latch control circuit. The latch arm is configured to be moved between a closed position that inhibits movement of the actuator arm assembly in a landing zone and an open position that does not inhibit movement of the actuator arm assembly in the landing zone. The coil is configured to generate an electromagnetic force on the latch arm responsive to a coil current. The permanent magnet is configured to generate a magnetic force on the latch arm that is substantially opposed to the electromagnetic force from the coil. The latch control circuit is configured to increase according to defined open current profiles over a defined opening time period the coil current to at least an upper defined level to cause the coil to move the latch arm from the closed position to the open position. The latch control circuit is further configured to decrease according to defined close current profiles over a defined closing time period the coil current to no more than a lower defined level to cause the permanent magnet to move the latch arm from the open position to the closed position.

A method of processing a transaction request at a database load balancer. The method comprises receiving the transaction request, where the transaction request is comprised of one or more operations; analyzing the transaction request to determine the one or more operations; associating one or more database locks with each of the one or more operations; analyzing one or more of the database locks to determine the one or more sequence numbers associated with each of the one or more operations; and transmitting the one or more operations with the associated database locks and the sequence numbers to one or more databases servers accessible to the database load balancer.

A metadata management system receives metadata changes and automatically updates a metadata architecture which maps the data. The metadata changes may be received through a simple user interface by a user or administrator. Once received, the system may automatically update schemas and data transformation code to process data according to the new data mapping preference. The system may handle metadata updates in a multi-tenant system having one or more applications per tenant, and may update data for a single tenant and 1 or more tenant applications in a multitenancy.
