Some embodiments of a method and an apparatus to deliver messages between applications have been presented. In one embodiment, a client supplied binding is received from a client, wherein the client supplied binding includes an XQuery or a script. A predefined binding is stored in a server, wherein said predefined binding includes an XQuery, a script, or a program, allowing the client to select the predefined binding. An exchange receives an Extensible Markup Language (XML) message from a publisher application and sends the XML message to each message queue whose binding matches the XML message.

Embodiments of the present invention provide a dynamic instrumentation system that uses statically defined probes. The probes may be defined using macro definitions. One or more libraries of macro definitions that are linked to static probes are provided in the computer system. Each probe is uniquely identified by a name having a well-defined prefix and a structured format. Probes may then be inserted at various locations and into the target software using standard macro calls. When the target software is compiled, the macro calls of each probe are expanded to calls to an existing function known as a probe handler function. Each probe handler function is identified in the computer system's symbol table with a unique symbol that corresponds to the name specified by the macro definition. When a probe is activated, the operating system kernel transfers control to an instrumentation kernel object. The instrumentation kernel object locates and runs the probe handler function to perform the actions requested for that probe.

System, method and computer program product for allocating physical memory to processes. The method includes enabling a kernel to free memory in a physical memory space corresponding to arbitrarily sized memory allocations released by processes or applications in a virtual memory space. After freeing the memory, the system determines whether freed physical memory in the physical memory space spans one or more fixed size memory units (e.g., page frames). The method further includes designating a status of the one or more page frames as available for reuse; the freed page frames marked as available for reuse being available for backing a new process without requiring the kernel to delete data included in the freed memory released by the process. The kernel may organize pages marked as available for reuse in one or more local 'pools' that is organized according to a variety of schemes which provide system efficiencies in that the kernel can eliminate the need for deleting of old data in those page frames without compromising data security.

Embodiments of the present invention provide methods and systems for tuning the size of the cache. In particular, when a page fault occurs, non-resident page data is checked to determine if that page was previously accessed. If the page is found in the non-resident page data, an inter-reference distance for the faulted page is determined and the distance of the oldest resident page is determined. The size of the cache may then be tuned based on comparing the inter-reference distance of the newly faulted page relative to the distance of the oldest resident page.

Embodiments of the present invention provide methods and systems for efficiently tracking evicted or non-resident pages. For each non-resident page, a first hash value is generated from the page's metadata, such as the page's mapping and offset parameters. This first hash value is then used as an index to point one of a plurality of circular buffers. Each circular buffer comprises an entry for a clock pointer and entries that uniquely represent non-resident pages. The clock pointer points to the next page that is suitable for replacement and moves through the circular buffer as pages are evicted. In some embodiments, the entries that uniquely represent non-resident pages are a hash value that is generated from the page's inode data.

Embodiments of the present invention provide a mechanism for certifying the compatibility of a software product by identifying the interfaces (API or ABI) used by that product. The source code or object code of a component is analyzed by a tool that traces which interfaces and data structures of an ABI/API are being utilized. For example, an ISV or IHV may be required to run the tool on their respective components in order to have that component certified with a particular version of an operating system and submit the results to a certification service. The certification service may collect this API/ABI information into an integrated database. The certification service may then use this database to analyze the impact of changes to an operating system at the binary interface level, proactively notify vendors prior to these changes, test compatibility and emulation libraries, and certify components are compatible with an operating system without the need of significant testing.

Techniques for virtualized computer system environments running one or more virtual machines that obviate the extra host operating system (O/S) copying steps required for sending and receiving packets of data over a network connection, thus eliminating major performance problems in virtualized environment. Such techniques include methods for emulating network FO hardware device acceleration-assist technology providing zero-copy I/O sending and receiving optimizations. Implementation of these techniques require a host O/S to perform actions including, but not limited to: checking of the address translations (ensuring availability and data residency in physical memory), checking whether the destination of a network packet is local (to another virtual machine within the computing system), or across an external network; and, if local, checking whether either the sending destination VM, receiving VM process, or both, supports emulated hardware accelerated-assist on the same physical system. This optimization, in particular, provides a further optimization in that the packet data checksumming operations may be omitted when sending packets between virtual machines in the same physical system.

A spam detection system (100) is illustrated for detecting unsolicited bulk emails (spam) according to an exemplary embodiment of the present invention. The spam detection system (100) includes a list server (110), a database (114), a plurality to senders (116) of email, and a plurality of mail servers (118). The list server (110) is used to receive and detect both regular email and unsolicited bulk email (spam). Accordingly, the list server (110) includes a plurality of spamtrap addresses (112). According to at least one embodiment of the present invention, the spamtrap addresses (112) correspond to email addresses that are monitored only for the receipt of unsolicited bulk email (spam). The list server (110) monitors the amount of spam received at the spamtrap addresses (112) in order to identify senders (116) that transmit spam. According to other embodiments of the invention, the list server (110) can count only emails that are received at more than one spamtrap address (112). Accordingly, if a particular spam message is only received at one spamtrap address (112), it may be discarded for purposes of identifying a sender (116) as a spammer. According to one or more further embodiments of the invention, spam messages are assigned higher weight factors (as will be described in further detail below) if they are received at more than one spamtrap address (112).
