Abstract: A solder ball attaching apparatus includes a working die, having an internal space maintained in a vacuum state, and a plurality of lifting members installed on the working die to be movable upwardly and downwardly. The working die may be provided with an upper plate on which the lifting members are installed. The upper plate may be provided with an insertion groove, into which an upper end portion of the lifting member is inserted when the lifting member is lowered, and a locking groove into which a lower end portion of the lifting member is inserted when the lifting member is raised. The lifting member may be lowered by a chip when the chip is seated on the lifting member and may be raised by elastic restoring force when the chip is removed.

Abstract: Disclosed is an operation method including generating RAID parity data based on first data in response to an RAID enable request and a first write request, the RAID enable request and the first write request being received from an external host, the RAID enable request including a first stream identifier and a RAID enable indication, and the first write request including the first stream identifier and the first data, storing the first data and the RAID parity data based on the first stream identifier, storing second data based on a second stream identifier in response to receiving a second write request from the external host, the second write request including the second stream identifier and the second data, and receiving an RAID disable request from the external host, the RAID disable request including the first stream identifier and a RAID disable indication.

Abstract: Examples include a ticketing system for managing performance of computer services. The ticketing system includes a ticket database to store a plurality of tickets, each ticket defining a job to be performed on a computing system, and a master to create a ticket, store the ticket in the ticket database, and update the ticket. The ticketing system includes a scheduler to determine whether to create the ticket based at least in part on a set of conditions, and to request the master to create the ticket when the ticket is to be created, and a worker to get the ticket from the master, perform the job defined by the ticket, and request the master to update the ticket with a status of the ticket. The ticketing system includes a supervisor to request the master to find a stale ticket, and, if found, to request the worker to abort performance of the job defined by the stale ticket.

Abstract: Examples include a computer-implemented method for determining one or more observations about a computing system, determining a plurality of sets of one or more actions based at least in part on a plurality of policies and the one or more observations; reducing the plurality of sets of one or more actions to generate a reduced set of actions, the reduced set of actions including scheduling a computing system to execute the reduced set of actions by requesting one or more idempotent tickets to be created in a ticketing system; and performing, or causing to be performed, the reduced set of actions.

Abstract: System and methods are described for restoring a database by receiving a request to restore a database in a cloud computing environment, generating a restore plan for the database based at least in part on previously stored database restore outcomes and error probabilities of full backups, incremental backups, and redo logs, restoring the database from an archive according to the restore plan, and storing an outcome of the database restore.

Abstract: In a cloud computing environment, a storage space management system provides for uniform collection of usage statistics for storage disks and storage consumers, including usage statistics for a consumers' storage buckets, where a storage bucket represents a logical container of files, objects or other types of stored data for a given consumer. The system enables automated evaluation of space usage policy against the collected statistics. The system enforces the evaluated policy determinations, including queueing jobs that manage storage disk eligibility for storing data and jobs that direct traffic from storage consumers to storage disks that have sufficient storage available.

Abstract: An automated self-healing database system is provided that includes a primary database, an application server that writes data to the primary database and reads data from the primary database when it is available, a standby database that is a replica of the primary database, and a self-healing module (SHM). The SHM can automatically detect unavailability of the primary database, and if the standby database is available, the SHM can automatically enable the standby database as readable and writable, assign the standby database the role of primary database at the primary site to start replicating data to other standby databases, and use a pre-established connection between the application server and the standby database to allow the application server to read data from the standby database and to write data to the standby database resulting in the standby database assuming role of the primary database at the primary site.

Abstract: System and methods are described for synchronization of delete operations between primary a secondary databases. The method includes identifying a chunk of records in a secondary database. The method also includes sending a message to a primary database that identifies the chunk of records and asks whether any records of the chunk records are delete-able. The method also includes receiving a response to the message from the primary database. The response indicates which records of the chunk records are delete-able. The method also includes deleting each record of the chunk of records from the secondary database that the message indicated was delete-able.

Abstract: In a cloud computing environment, a cluster backup management system of a database storage system directly determines which nodes in the cluster are suitable for use in backup operations without relying on a static configuration. The system automates sampling of the status of each node in a storage cluster and evaluating the health of a node to determine whether it is eligible to support a backup operation. A backup job scheduling and execution process uses the sampled status and health evaluations to automatically determine which nodes are eligible to use for backup operations.
