摘要:
A diagnosability system for automatically collecting, storing, communicating, and analyzing diagnostic data for one or more monitored systems. The diagnosability system comprises several components configured for the collection, storage, communication, and analysis of diagnostic data for a condition detected in monitored system. The diagnosability system enables targeted dumping of diagnostic data so that only diagnostic data that is relevant for diagnosing the condition detected in the monitored system is collected and stored. This in turn enables first failure analysis thereby reducing the time needed to resolve the condition detected in the monitored system.

Techniques for indicating the status or health of a software system in a simple and summarized manner. In one embodiment, a health meter is displayed that displays a status value indicating the status or health of the software system. The status or health of the system as indicated by the health meter may be based upon one or more characteristics or perspectives (or components) of the system, such as performance, resource utilization, reliability, availability, scalability, and status values computed for the components.

摘要:
A method and apparatus for capturing database system workload and replaying that workload in a database system is provided. According to one aspect, in order to subject a test database system to the same workload to which the production database system actually would be subjected, a database server in the production system captures and records workload that the database server receives from external entities. This captured workload is processed. Processes external to a database server in the test database system send the processed workload to that database server. As a result, the test database system is subjected to the same workload to which the production database system originally was subjected. The foregoing technique permits a database administrator to determine how the production database system will fare if the difference that is present in the test database system is introduced into the production database system.

摘要:
Various embodiments of the invention provide solutions that can offer a consistent framework for tools that assist in the configuration, tuning, and/or troubleshooting of a database and/or an RDBMS. Merely by way of example, one set of embodiments provides a software framework for an advisor component of a database and/or RDBMS. In accordance with some embodiments, the framework might specify a common data model for such advisor components. The data model can include, merely by way of example, a set of one or more findings (which might, in some cases, describe the result of an analysis of a circumstance in the database, RDBMS, and/or a mid-tier application used with the database) and/or a set of one or more recommendations (which might provide suggestions for addressing the circumstance). In particular embodiments. In particular embodiments, the data model might include a set of on or more rationales, which can explain the recommendations. In some cases, the software framework might include a task associated with the advisor component and/or one or more interfaces, which can include, inter alia, user interfaces and/or APIs. Other sets of embodiments can provide methods, systems and/or software programs for implementing an advisor framework.

摘要:
A process is described to form a semiconductor device such as MOSFET or CMOS with shallow junctions in the source/drain extension regions. After forming the shallow trench isolations and the gate stack, sidewall dielectric spacers are removed. A pre-amorphizing implant (PAI) is performed with Ge+ or Si+ ions to form a thin PAI layer on the surface of the silicon regions adjacent to the gate stack. B+ ion implantation is then performed to form source/drain extension (SDE) regions. The B+ implant step is then followed by multiple-pulsed 248 nm KrF excimer laser anneal with pulse duration of 23 ns. This step is to reduce the sheet resistance of the junction through the activation of the boron dopant in the SDE junctions. Laser anneal is then followed by rapid thermal anneal (RTA) to repair the residual damage and also to induce out-diffusion of the boron to yield shallower junctions than the just-implanted junctions prior to RTA.
