A system and method of deploying software provides for comparing a current software topology of a deployment site to a software deployment topology of an application, wherein the software deployment topology is required to deploy the application. One or more mismatches between the current software topology and the software deployment topology may be identified.

Deployment and deployment planning as a service

Systems, methods and computer program products manage computing resources for a system. A system includes a set of processors having multiple processor cores present in the computer system, where the processor cores form an aggregated set of processor cores for the system. A dependency analyzer determines dependencies among a set of workload components executing on the set of processor cores. A policy includes rules associated with managing one or more of power consumption, heat production, operating cost or workload balancing for the set of aggregated processor cores. In response to a workload event, a management component sets a state of one or more of the processor cores in accordance with the workload event, the policy and the set of dependencies.

Managing computing resources through aggregated core management

Methods, systems, and computer program products for dynamically modifying an application program's behavior in response to changing environmental conditions (such as network changes, system changes, and so forth). The application may solicit such information, and/or may receive unsolicited environmental change notifications. In response to a change notification, the application may take one or more of the following approaches to adapt to the changing conditions: (1) alter its execution; (2) modify its use of, or control of, other cooperating application; and (3) modify the selection of application execution threads. (An application might also decide to make no changes in its behavior.)

Dynamic modification of application behavior in response to changing environmental conditions

A method, computer program product and network management server for distributing software. The network management server receives a request to deploy an application on a designated target client station at a designated scheduled time. The network management server determines whether to deploy the application on the designated target client station at the designated time based on the resource state of the systems involved in the deployment of the software (e.g., processor usage of the network management server, processor usage of the target client station) as well as the environmental conditions (e.g., bandwidth usage, time of day pricing for connectivity at scheduled time, work orders on the target client station). By taking into consideration the dynamic resource state of the systems involved in the deployment of the software as well as the environmental conditions, software may be deployed on the client stations by the network management server more effectively.

A configuration management database (CMDB) that associates a policy with a configuration item (CI) in the CMDB. The policy contains an 'applies to' field and a 'type descriptor'. When a relationship is created between the CI and a second CI in the CMDB, the policy is associated with the second CI. The type descriptor of the policy may be evaluated and the policy associated with the second CI in response to the evaluation. The policy may contain a type descriptor comprising an instance of a CI type. The policy may contain a type descriptor comprising a CI type. The policy may contain an &#x201c;applies to&#x201d; field having a value of &#x201c;this CI type&#x201d;. The policy may contain an &#x201c;applies to&#x201d; field having a value of &#x201c;hosting environment of this CI type&#x201d;. The type descriptor may include a hosted CI component portion and a hosting CI component portion.

CMDB-based policy propagation

A computing services grid. The grid can include a service desk coupled to one or more computing service instances. Each service instance can conform to an interface which is common to all service instances in the grid. A routing component can be disposed in the grid. Specifically, the routing component can route individual service requests to individual ones of the service instances. An instance selection service is used to satisfy QoS characteristics associated with the requester of the service. The grid further can include a service instance monitoring component. The monitoring component can monitor the performance of individual service instances charged with processing individual service requests. Fail-over logic can be configured to re-route service requests from selected service instances to others of the service instances where the monitoring component detects a fail-over condition in the selected service instances. In that regard, fail-over conditions can include error conditions and a performance deficiency conditions in which the performance of a selected service instance lags behind guaranteed levels of performance.

A method, apparatus, and computer instructions are provided for storage provisioning automation in a data center. A storage manager is provided in the present invention to facilitate end-to-end deployment of storage resources for a server in the data center. The storage manager includes functionalities of a volume manager, file system, and physical volumes. In addition, a hierarchical structure is provided by the present invention to specify configuration data for a volume container. The hierarchical structure includes volume container settings, which includes physical volume settings and logical volume settings linked through data partition settings. For SAN volumes, storage multipath settings and data path settings are included in the structure. File system settings and mounting settings are also included to mount a file system once it is created.

Methods, systems, and computer program products for improving data transfer in complex computing environments. Internal routing enhancements are defined, which enable traffic of virtual servers to be processed more efficiently, thereby improving overall data transfer rates. Instead of performing routing operations in the Internet Protocol ('IP') layer of a networking stack, a 'mini-routing' table is created programmatically and is used to perform routing at the Data Link Control (&#x201c;DLC&#x201d;) layer. This technique avoids bottlenecks in the IP layer and speeds the data transfer process.

Fast path routing in a large-scale virtual server computing environment

An application server running an SNA application includes a TN3270 server. Performance of the application server is enhanced by relocating away from the application server the conversion of data between ASCII and EBCDIC, as well as command scanning and packaging. The relocating can take the form of, for example, a browser plug-in at the client or elsewhere. In addition, the client is able to carry on communications with the application server over a standard port by logically situating a communication server between the client and the application server. The client communicates with the communication server over the standard port, while the communication server forwards the communications to the application server over a non-standard port.

Enhancing application server performance by relocating performance-degrading processing

A problem determination method, system and program product are provided. Specifically, the present invention identifies problems with software programs by inserting compiled problem determination probes into program classes while the computer system on which the program is loaded is running. Once the probes have been inserted, the classes will be run and trace data will be generated. The trace data can be retrieved and analyzed to identify and address the problem. When the probes are no longer needed, they can be removed while the computer system continues to run.

A dedicated processor for efficient processing of documents encoded in a markup language, such as XML. The dedicated processor is capable of performing traditional parsing, transformation and manipulation processes on the document. The special purpose processor frees a general purpose processor to perform other tasks, resulting in an increase in system performance. In one embodiment, the dedicated processor includes a general purpose processor and suitable software which is provided in addition to the general purpose processor which has been traditionally used for processing. In such an embodiment, the dedicated processor may be implemented in a multi-processor system. In another embodiment, the dedicated processor is implemented in special purpose hardware, e.g. as an integrated circuit embodied in silicon in one or more chips. In either embodiment, the dedicated processor may be provided to offload processing locally or remotely.

A value-based caching system and method. A value based cache method can include partitioning a cache into different value-based partitions. Data to be stored in the cache can be valued and the valued data can be cached in individual ones of the value-based partitions. Subsequently, cache entries can be evicted from the value-based partitions. Finally, the caching and evicting can be managed according to the valuing step. In this regard, the cache and eviction management step can ensure greater cache responsiveness for data having a greater value relative to other valued data.

Value based caching

Management of datastream construction prior to transmission of the datastream across a channel of a communications system by providing for data blocking while reducing movement or copying of the data improves the performance in a communications system. Multiple header segments received from a higher layer in the communications stack are copied into the datastream header area of a datastream such that the header segments are sequentially stored in the datastream header area. A datastream buffer list having entries referencing the datastream header area is generated. Buffer list entries referencing data segments received from higher layers in the communications stack are also stored in the datastream buffer list. The data segments are not physically moved or copied into the datastream during processing by the communications stack. Rather, a 'virtual' datastream is generated by the communications stack for transmission without physically moving or copying the data segment. The datastream is transmitted across the channel by the system input/output interface by first writing the datastream header area referenced by the datastream buffer list directly into the channel, and the data segments directly from their original storage location into the channel of the communications system using the datastream buffer list entries.
