Method of controlling whether an uncompleted transaction applied against a database goes forward using either synchronous or asynchronous replication, or using either encrypted replication or unencrypted replication
Transactions are applied against a database on a transaction processing system.

Collected attributes of the joined uncompleted transaction are compared against rules in a rules engine that are applicable to the transaction to determine whether an applicable rule in the rules engine is met. The joined uncompleted transaction is allowed to go forward and be applied against the database of the transaction processing system using a synchronous replication engine when the applicable rule is met, and an asynchronous replication engine when the applicable rule is not met. Alternatively, the joined uncompleted transaction is allowed to go forward using a replication engine that replicates using encryption when the applicable rule is met, or replicates unencrypted when the applicable rule is not met. |

Sharing message-signaled interrupts between peripheral component interconnect (PCI) I/O devices
A PCI function, such as a device driver, may request that additional MSI resources be allocated to an I/O device coupled to a PCI Host Bridge (PHB).

For example, the PCI function requesting the additional MSI resources may ask for a certain number of MSI resources for a certain period of time—e.g., a lease. The hypervisor then determines which of the other PCI functions (referred to as a loaning PCI functions) are willing to lend or loan their MSI resources. Once the MSI resources available for lease are known, the hypervisor informs the requesting PCI function of these resources which, in turn, binds the additional MSI resources to the I/O device. |

Method for remote asynchronous replication of volumes and apparatus therefor
A method for remote asynchronous volume replication and apparatus therefore are disclosed. Asynchronous replication is applied to deal with data changes on the source volume on the local site incurred by Host IO requests. In coordination with the “point-in-time differential backup” technology, the data is subjected to be backuped to Source BAS on the local site (backup-on-write operation) only when the original data being written into the block of the source volume is different from the data of the corresponding block of the destination volume on the remote site.

Therefore, the data necessarily transmitted to the destination volume on the remote site can be minimized, and the problem of remote data transmission limited by network bandwidth can be prevented effectively, thereby keeping the operation performance of the storage system at a better level. |

Efficient priority-aware thread scheduling
A priority-based scheduling and execution of threads may enable the completion of higher-priority tasks above lower-priority tasks. Occasionally, a high-priority thread may request a resource that has already been reserved by a lower-priority thread, and the higher-priority thread may be blocked until the lower-priority thread relinquishes the reservation. Such prioritization may be acceptable if the lower-priority thread is able to execute comparatively unimpeded, but in some scenarios, the lower-priority thread may execute at a lower priority than a third thread that also has a lower priority than the high-priority thread. In this scenario, the third thread is effectively but incorrectly prioritized above the high-priority thread. Instead, upon detecting this scenario, the device may temporarily elevate the priority of the lower-priority thread over the priority of the third thread until the lower-priority thread relinquishes the resource, thereby reducing the waiting period of the high-priority thread for the requested resource. |

Inspection device
An inspection device is required to detect a minute defect, that is, to have high sensitivity as semiconductor devices become finer. There are some approaches for improving the sensitivity. One is to shorten the wavelength of illuminating light radiated onto a sample.

Another approach is to use illuminating light including multiple wavelengths. An approach for taking in more scattered light generated from the sample is also possible. However, an optical system suitable for these approaches has not been sufficiently found in conventional techniques. One feature of the present invention is to detect a defect by using a Wolter optical system including a Wolter mirror. |
