Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 3/00
G06F 13/00

US Classification:

710 5, 710 33

Abstract:

A computer implemented method, an apparatus, and a computer usable program product for tracking device driver requests in a data processing system is provided. A controller receives a request from a device driver. The controller associates a timestamp and at least one pointer to the request, wherein the timestamp indicates a time the request is received by an operating system. The controller then links the request from the device driver in a queue in the operating system, wherein the pointer identifies the location of the request in the queue.

International Classification:

G06F 9/46

US Classification:

718105

Abstract:

A system for balancing component load. In response to receiving a request, data is updated to reflect a current number of pending requests. In response to analyzing the updated data, it is determined whether throttling is necessary. In response to determining that throttling is not necessary, a corresponding request to the received request is created and a flag is set in the corresponding request. Then, the corresponding request is sent to one of a plurality of lower level components of an input/output stack of an operating system for processing based on the analyzed data to balance component load in the input/output stack of the operating system.

Abstract:

A mechanism is provided for automatically closing a file or a device. A service routine monitor monitors a request received from either an application that opened the file or a device driver that readied the device. The service routine monitor determines whether the file or the device has been accessed within a predetermined time interval. Responsive to the file or the device failing to be accessed within the predetermined time interval, the service routine monitor sends a call to the application that opened the file or the application or a higher level device driver that requested that the device driver ready the device. Responsive to a response from the application or the higher level device driver indicating that the use of the file or the device is no longer needed, the service routine monitor closes the file or quiesces the device.

US Classification:

711162, 711161, 711E12001, 711E12013

Abstract:

A computer implemented method for automatically managing copies of source data volumes is provided. A copy management agent receives a message that target volume copies of source volumes are available. The copy management agent accesses the target volume copies of the source volumes. The copy management agent analyzes metadata for the target volume copies. The copy management agent determines whether any of the target volume copies is a boot volume copy based on the analyzed metadata. In response to a determination that one of the target volume copies is a boot volume copy, the copy management agent directs a provisioning agent to provision a new host for the target volume copies. The copy management agent directs the storage subsystem to present the target volume copies to a storage area network port associated with the new host. Then, the new host is booted using the boot volume copy.

US Classification:

709206, 709224

Abstract:

There is set forth herein a computer program product, computing device, and method for displaying an email message. In one example, a computing device receives an input comprising at least one criterion for redacting email messages; stores the at least one criterion in a configuration of a client computer program; receives an email message having a field, the field comprising a first content; determines whether a condition of at least one of the email message and a current state of the computing device satisfies the at least one criterion stored in the configuration of the client computer program; and, in response to determining that the condition satisfies the at least one criterion, displays a second content in place of the first content in a user interface of the client computer program, wherein the second content is different than the first content.

US Classification:

717128

Abstract:

Provided are techniques for the tracing of computer processes and, more specifically, to techniques that enable a work unit to be traced across multiple processing components. A data structure is created and associated with a work unit. The first time a unit of work is processed a tracing context is retrieved form a pool and associated with the data structure. As the unit of work is passed from component to component, the data structure is passed so that each component has access and is able to augment the same tracing context associated with the unit of work.

Abstract:

A sync manager invokes a scheduled sync task that includes filter attributes for filtering a plurality of memory pages into a subset of memory pages. The sync manager selects file pointers that correspond to a plurality of files and traverses through the files using the selected file pointers. While traversing, the sync manager extracts file attributes for each of the files and, in turn, filters the files by comparing the filter attributes with the extracted file attributes. The sync manager then extracts memory page identifiers that correspond to the filtered files and synchronizes a subset of memory pages using the extracted memory page identifiers.
