摘要： A method, system and article of manufacture for estimating the performance of a computer system are provided. Initially, a business pattern representative of the expected usage of the computer system is identified. Then, for each parameter associated with each predefined script, which corresponds to the identified business pattern, a value is established. The computer system hardware characteristics and performance objectives are identified next. The performance estimate is then calculated utilizing the established parameter values, identified hardware characteristics and performance objectives. To calculate the performance estimate, the script measurements data is read from a table of previously measured values, and a weighted average number of page visits per user, a weighted average visit rate and a weighted average service time for each target device in the computer system are calculated. A total response time and a system throughput are calculated by varying each target device queue length and user arrival rate until the performance objectives are reached.

摘要： Automated or autonomic techniques for managing deployment of one or more resources in a computing environment based on varying workload levels. The automated techniques may comprise predicting a future workload level based on data associated with the computing environment. Then, an estimation is performed to determine whether a current resource deployment is insufficient, sufficient, or overly sufficient to satisfy the future workload level. Then, one or more actions are caused to be taken when the current resource deployment is estimated to be insufficient or overly sufficient to satisfy the future workload level. Actions may comprise resource provisioning, resource tuning and/or admission control.

摘要： An on-demand manager provides an improved distributed data processing system for facilitating dynamic allocation of computing resources among multiple domains based on a current workload and service level agreements. Based on a service level agreement, the on-demand manager monitors and predicts the load on the system. If the current or predicted load cannot be handled with the current system configuration, the on-demand manager determines additional resources needed to handle the workload. If the service level agreement violations cannot be handled by reconfiguring resources at a domain, the on-demand manager sends a resource request to other domains. These other domains analyze their own commitments and may accept the resource request, reject the request, or counter-propose with an offer of resources and a corresponding service level agreement. Once the requesting domain has acquired resources, workload load balancers are reconfigured to allocate some of the workload from the requesting site to the acquired remote resources.

摘要： An apparatus, system, and method are disclosed for provisioning database resource within a grid database system. The apparatus comprises an analysis module and a provision module. The analysis module analyzes a data query stream from an application to a database instance and determines that the data query stream exhibits a predetermined performance attribute. The provision module provisions a database resource in response to a determination that the data query stream exhibits the predetermined performance attribute. The provisioned database resource may be a database instance, a database server, or a cache. The provisioning of the new database resource advantageously is substantially transparent to a client on the database system.

摘要： An apparatus and method for distributed intersystem lock optimization are provided. With the apparatus and method of the present invention, the time required to obtain an uncontested lock, meaning a lock that no other program or process in the distributed system is simultaneously attempting to acquire, is minimized. The apparatus and method of the present invention increases the speed with which locks are acquired by splitting the process of obtaining a lock into two separate operations: a test for contention, and then if contention exists, a full lock operation. The test for contention is made fast by associating each lock with a memory location, and using an atomic operation or the like, to atomically set the memory location associated with the lock to a different value. If the lock is found to be contested, meaning that another program or process has already locked it, control is turned over to a slower operation than ensures that the lock-requesting program or process will eventually be granted the lock.

摘要： The present invention discloses a method, system and article of manufacture for performing analytic modeling on a computer system by handling a plurality of predefined system criteria directed to a modeled computer system. The present invention provides means for the user of an analytic model to specify (i.e. enable) any number of predefined system criteria that must all be simultaneously satisfied. The modeling methodology uses a variation of the well-known Mean Value Analysis technique in its calculations. Response times, resource utilizations, and resource queue lengths are initially estimated for a small user arrival rate. An iterative method is used to gradually increase the user arrival rate by a constant value. For each iteration, response times, resource utilizations, and resource queue lengths are calculated. Then for all the criteria, which have been enabled, it is checked to see if the value limits specified for those criteria have exceeded. If not, the model calculation results are saved and next iteration is started. The model iterations continue with a gradually increasing user arrival rate until one or more of the modeling criteria are exceeded. At that time the model outputs the results from the previous iteration (i.e. the saved results where all the criteria were still satisfied), and the modeling calculations are finished. The model results may be used as input for further processing.

摘要： A method, apparatus, and computer implemented instructions for managing a plurality of caches of data, wherein the data processing system includes a plurality of independent computers. In response to initiating a read operation to read data on a data block, an indication is posted on a directory of data blocks identifying the computer that now holds a copy of that block and a location in the memory of that computer where a flag associated with that block is held. Then in response to initiating a write operation on that data block, messages are sent to all the computers holding that block which resets the said flag, thus informing each computer that the data in that block is no longer valid. These messages are sent using means that perform that flag reset without, in the preferred embodiment, any overhead of interruption of processing on the computers where the flags reside.
