Abstract: A method, system, and apparatus for controlling the behavior of an application through a device or device subtype in a logical volume manager. The present invention allows for creating device types or subtypes to be used when creating a logical volume. The device type or device subtype specified during the creation of the logical volume signals to an application that the application may perform a particular behavior. The use of alternate device types and subtypes when creating a logical volume inform an application that the application can behave in a new way defined by the device type and subtype.

Abstract: A method and apparatus in a data processing system for providing access to resources within the data processing system. A request is received from a requestor to access a resource in the data processing system. A cookie is sent to the requestor, wherein the cookie is used to access the resource. An identification of the requestor and the cookie is stored to form a stored identification and a stored cookie. Responsive to receiving a subsequent cookie from a source, an identification of the source and the cookie is compared with the stored identification and the stored cookie. Responsive to a match between the identification of the source and the cookie and the stored identification and the stored cookie, access to the resource is allowed.

Abstract: A system, apparatus and method of notifying a user that there may be a possibility of communicating with a computer system other than an intended one are provided. When a host in use by the user is to request a DNS name service, the request is sent to two or more DNS servers. If all the servers return the same IP address, then there is a likelihood that the user may communicate with the intended computer system. If, however, two or more different IP addresses are returned, there is a high likelihood that the user may communicate with a computer system other than the intended one. When this occurs a warning is generated notifying the user of such a likelihood.

An implementation is provided at the receiving Web station for determining whether a received web document has been preselected for downloading in a text-only mode, and in responsive to this determination, there is an implementation for downloading such received preselected Web documents in a text-only mode. The user is enabled not only to designate specified documents to be downloaded in a text-only mode but the user may also preselect whole World Wide Web domains or specified Web sites within such domains from which received Web documents are to be downloaded in a text-only mode.

Abstract: A method, system, and program for fast paging of a large memory block are provided. A request to physically remove a memory block device from a data processing system is received. A logical volume within disk space is dynamically allocated for a contiguous paging space. Multiple logical pages for the memory block devices are translated into multiple physical addresses for the memory block device. A single input/output request is issued to page out data located at the multiple physical addresses to the contiguous paging space, such that after the single request is complete, the memory block device can be safely removed. Further, when a replacement memory block device is detected, a single input/output request is issued to page in data located within the contiguous paging space to the replacement memory block.

Abstract: A method, system and apparatus for allowing a mirroring map to be used with more than one piece of data are provided. First, a mirroring map is created and given a name. Then, the name of the mirroring map and the mirroring map itself are stored into the computer system. When a piece of data is to be stored in accordance with the mirroring map any time thereafter, the name of the mirroring map is used to associate the mirroring map with the piece of data.

Abstract: A method, system and token are described which control access to a token server system. In a first aspect, a method and system for controlling access to a file system of a token server comprise encoding a time specific permission into a token. In a second aspect, a token server system comprises at least one client and a token server accessible by the at least one client. The token server provides a token to the at least one client to allow the client to have access to the data on the token server. The token includes a time specific permission. In a third aspect, a token for use in a token server system comprises a group of privileges and security identifiers. The token includes a time specific permission. A system and method in accordance with the present invention controls access to networked systems, but does not totally disable or change a system to accommodate temporary outages of access.

Abstract: A system and method for performing a point in time backup is presented. A backup application initiates a point in time backup whereupon a backup tracker monitors write requests during the point in time backup. The backup tracker logs data block locations that have already been backed up whose content changes in response to a write request. After a first pass of backing up data blocks, the backup application backs up the changed data blocks. During the changed data block backup procedure, the backup application invokes a copy on write command for particular changed data blocks that receive write requests prior to their content being backed up. The copy on write command stores the particular changed data block's content in a temporary storage area in which the backup application retrieves when the backup application is ready to backup the particular changed data blocks.

Abstract: A system and method for designating and deleting expired files includes a means for storing expiration dates along with file identification data maintained by the file system. An earliest expiration date is stored in data maintained by the file system pertaining to each directory. In this manner, a check of the directory data indicates whether one or more expired files exist in the directory. The system date is compared to the earliest expiration date for a directory, for example when a “list contents of directory” command is received. If the earliest expiration date is earlier than the system date then a comparison is made with the files in the directory and individual files with expiration dates earlier than the current date are deleted. The earliest expiration date is then update to the correspond to the next earliest expiration date falling after the current date.

Abstract: The present invention is embodied in a system and method for monitoring and alerting remote client users of digital intrusions of their computers by host servers. In general, the present invention monitors actions taken by host servers relating to information about the remote client and displays graphical alerts when a digital intrusion or a breach of security occurs during a network connection, such as a connection to the Internet, with the host server. Specifically, the present invention monitors certain aspects of the remote client user s interaction with host servers. Based on certain interaction, such as an attempt by the host server to retrieve non-related information about the remote client, the remote client user can be provided with a graphical alert. This allows the remote client user to make an informed decision whether or not to allow certain host server sites to retrieve the client user s personal information.

Abstract: A path control module manages a set of primary paths and a set of standby paths for a target device. When a path in the set of primary paths fails, the path control module may failover to the set of standby paths. Alternatively, when a path in the set of primary paths fails, the path control module may failover that path to a single path from the set of standby paths. The sets of primary paths and standby paths may be set by an administrator to control load balancing of resources in the storage area network. The primary set of paths for a first disk may be the standby set of paths for a second disk. Similarly, the primary set of paths for the second disk may be the standby set of paths for the first disk.

Abstract: A system, apparatus and method of allowing an application program continued access to a frozen file system are provided. An application program that requires continued access to a file system, even when the file system is frozen, may register with the system. Doing so allows the system to identify application program as one that needs continued access to the file system. Hence, the application program may continue to be provided access to the file system while all other application programs are prevented from accessing the file system.
