Abstract: A method, apparatus, and computer program product dynamically allocate limited system memory for direct memory access (DMA) among a plurality of input/output (I/O) adapters in a system partition. Initially a minimum entitlement of I/O entitled memory capacity is allocated to each of the respective multiple I/O adapters. The minimum entitlement enables operation of an I/O adapter driver. Additional entitlement of I/O entitled memory capacity is selectively allocated based upon I/O demands of each I/O adapter.

Abstract: A method, a system and a computer program product for matching a publication to at least one subscriber are disclosed. After receiving a publication request, a matching engine accesses a hash table to determine whether there is a non-wildcarded match corresponding to the publication request. If the matching engine finds the non-wildcarded match in the hash table, the matching engine omits validating a topic of the publication and provides the non-wildcarded match to the broker device without waiting for a result of searching a wildcarded match. Otherwise, the matching engine validates the topic of the publication. The matching engine also starts to search a wildcarded match in a wildcarded subscription data store. Upon finding the wildcarded match, the matching engine provides the wildcarded match to the broker device. The matching engine provides each result of the findings asynchronously to the broker device.

Abstract: When an email server has a message from a sender to multiple recipients with an attachment file, an attachment application is activated. The attachment application stores preferences of email users for online storage locations. The method carried out extracts details of an email sender and recipients for the email message to be sent with an attachment file and compares the email sender and recipients with the stored preferences for online storage locations to select a common online storage location for the sender and recipients. A directory is created at the common online storage location for uploading the attachment file to the selected online storage location and the address of the attachment file at the selected online storage location is added to the email message. If a common online storage location is not available, a new account can be generated for the recipients at an online storage location.

Abstract: A method and system for controlling message throughput rates of clients connected to a broker device in a publish/subscribe network are disclosed. The broker device determines a maximum allowable message throughput for each client connected to the broker device. If a message-producing rate of a client exceeds the maximum allowable message throughput of the client, the broker device sends a negative acknowledgement (NACK) packet to the client and messages from the client are not accepted at the broker device. The NACK packet includes a maximum allowable message throughput of the client, so the client can adjust its message-producing rate based on the maximum allowable message throughput of the client. The present invention can be applied to a publish/subscribe network as well as a TCP/IP network.

Abstract: A method, computer program product, and apparatus for monitoring patterns of motion are provided. A signal is received from a sensor on a user, wherein movement of the user causes the sensor to generate power to emit a signal indicative of the movement of the user. The signal is analyzed to form a current pattern of motion. The current pattern of motion is compared to a baseline pattern of motion associated with the user. A difference between the current pattern of motion and the baseline pattern of motion associated with the user is determined to form a difference. The difference is compared to a predetermined threshold. Responsive to the difference exceeding the predetermined threshold, an alert is sent.

Abstract: A system, method, and computer-implementable method for aiding file searching within a file service by indexing historical filenames and locations. In response to receiving a request to alter a first name corresponding to a file within the file system to a second name, a file system manager associates the second name to the first name and to the file within the file system data structure. When receiving a request for a file, wherein the request includes the first name, the file system manager searches the file system for the file based on the first name. When determining the search based on the first name is not successful, the file system manager searches the file system data structure for the file based on the second name. When the second name is located within the file system data structure, the file system manager returns the file to fulfill the request.

Abstract: A method of reducing the window of malicious exploitation between vulnerability publication and the installation of a software patch. One or more probe points are inserted into a code path in an application (or operating system if applicable) that contains one or more vulnerabilities (or coding errors). The probe points mark locations of the security vulnerabilities utilizing software interrupts to enable the original code base of the code path to remain unmodified. A probe handler utility subsequently monitors the execution of the code path and generates an alert if the execution reaches a probe point in the code path, thus indicating whether the application exhibits a particular vulnerability. The probe handler selectively performs one of multiple customizable corrective actions, thereby securing the application until an applicable software patch can be installed.
