Abstract: A system and method can support dynamically scaling up/down transactional resources in a transactional middleware machine environment. Transactional resources, such as groups and machines, can be by added or removed using a dynamic resource broker according to resource usage changes. The transactional middleware machine environment can comprise a deployment center in the transactional middleware machine environment, wherein the deployment center maintains one or more deployment policies for the transactional middleware machine environment and one or more deployment agents. Each of the one or more deployment agents is associated with a transactional middleware machine of a plurality of transactional middleware machines in a transactional domain in the transactional middleware machine environment.

Abstract: A server computing system in a client-server computing environment includes a virtual display driver that marshals and transmits graphics application programming interface (API) functions to a client via a network. The server may receive capability information from the client, allowing the virtual display driver to resolve differences between the APIs supported on the server and the client.

Abstract: A system, method and computer program product for system for detecting a rootkit on a computer having an operating system, including a native application in ring 0 which, when the operating system is in a trusted state upon a reboot of the computer, after loading of the boot drivers but before loading of non-boot drivers, generates a first snapshot for selected files of the operating system and for a registry; the first snapshot being stored on a persistent storage medium of the computer; a second snapshot for the selected files and for the registry generated by the ordinary application after the loading of the non-boot drivers, generating; means for comparing the second snapshot with the first snapshot; and upon detecting, in the comparing step, one of a masked file and a masked registry branch, means for informing a user of possible rootkit presence on the computer.

Abstract: An adaptive compression technique which is an improvement to Lempel-Ziv (LZ) compression techniques, both as applied for purposes of reducing required storage space and for reducing the transmission time associated with transferring data from point to point. Pre-filled compression dictionaries are utilized to address the problem with prior Lempel-Ziv techniques in which the compression software starts with an empty compression dictionary, whereby little compression is achieved until the dictionary has been filled with sequences common in the data being compressed. In accordance with the invention, the compression dictionary is pre-filled, prior to the beginning of the data compression, with letter sequences, words and/or phrases frequent in the domain from which the data being compressed is drawn. The letter sequences, words, and/or phrases used in the pre-filled compression dictionary may be determined by statistically sampling text data from the same genre of text.
