Abstract: A remote client screen shots monitoring system for monitoring at least one client includes a preboot execute environment (PXE) module, a terminal multiplexing module, and a monitoring module. The PXE module controls the client to boot up. The client executes operations after booting us and generating screen shots in the process.

The terminal multiplexing module places each generated screen shot together with those of other monitored clients in a display. The monitoring module can accordingly determine whether a fault exists in any one client. A remote client screen shots monitoring method is also provided.

Abstract: The embodiments described herein provide systems and methods for recovering resources in processing devices. Specifically, the embodiments described herein provide techniques for recovering leaked resources allocated to hardware engines in a hardware processing core. As one example, the recovery of resources allocated to hardware engines can be facilitated by making a specified register available to monitoring software. When leaked or otherwise stuck resources are identified, the monitoring software can set the register to trigger the recovery of those resources. This recovery of resources can be then performed by stopping the execution of processes in the hardware engines, invalidating the resources previously allocated to the hardware engines, initializing the resources, and starting the handling of new processes in the hardware engines. This process effectively recovers those resources, and allows those hardware engines to quickly resume operations.

Abstract: Embodiments enable a database management system (DBMS) to manage two levels of disk failure groups. These two levels of redundancy are achieved by grouping the disks of the disk group for the DBMS into two levels of failure groups (i.e., “data sites” each containing two or more “failure groups” of disks). This system of disk grouping allows a DBMS to potentially tolerate the loss of both an entire first site and part of a second site. Such a DBMS uses a multi-level voting system, based on both failure group-level votes and site-level votes, to identify the current version of administrative data structures (ADS) that store key administrative data. In addition to data sites that store database data, the DBMS includes a quorum site with a single quorum failure group that stores a copy of the ADS. The quorum site contributes a site-level vote during a multi-level voting event.

The RAID controller is configured to perform a first rebuild operation using the first parity bit and a first policy having a first rebuild rate, to perform a second rebuild operation using the first and second parity bits and a second policy having a second rebuild rate, to apply a first sub-rate as the first rebuild rate until the I/O rate reaches a predetermined value, and to apply a second sub-rate as the first rebuild rate when the I/O rate is greater than the predetermined value.
