Techniques for protecting content to ensure its use in a trusted environment are disclosed. The stored content is protected against harmful and/or defective host (or hosted) environments. A trusted security component provided for a device can verify the internal integrity of the stored content and the host before it allows the content to come in contact with the host. As a counter part, a trusted security component provided for the host can verify and attest to the integrity of the host and/or specific host computing environment that can be provided for the content stored in the device. The trusted security component provided for a device effectively verify the host integrity based on the information attested to by the trusted security component provided for the host. If the trusted security component trusts the host, it allows the trusted host to provide a trusted host computing environment trusted to be safe for the content stored in the device. A trusted host can effectively provide a safe virtual environment that allows a content representing a copy (or image) of an original computing environment to operate on the host computing system to give a similar appearance as the original computing environment.

The present invention describes a new system and method for modeling and dynamically deploying services into a distributed networking architecture, especially in a service-oriented architecture. The service container being part of distributed networking architecture exposes its functionality as services. It provides a registration service for deploying service descriptions. Having created a new service description in any declarative description language (i.e. a description of a (stateful) service e.g. a stateful Web service), the description provider invokes the registration service at the service container that allows to register (i.e. deploy) that new service description during runtime without restarting service container. The service container is responsible to analyze and check the submitted new service description for validity, to store the service description and to make it available for interested services consumers for instantiation. If a new service has been successfully registered, a new service interface for accessing that new service is automatically created by the service container. Interested services consumers may query the hosting environment for the available services being hosted and to subsequently instantiate a new service. A service consumer may then invoke any exposed service operation on a given service instance which generally follows a request response pattern.

Alternatively, the system may include a SCM as an add-on module to an untrusted host environment. Only authenticated applications including COTS OS execute on the SCM while untrusted applications execute on the untrusted host environment. The SCM may control secure resource access from the untrusted host through a plug-in module interface. All secure resources may be maintained on the trusted side of the plug-in module interface.

The present invention extends to methods, systems, and computer program products for accessing network resources outside a security boundary. The present invention can provide a modules running within a security boundary (e.g., sandboxed client-side scripts) access to network resources at computer systems other than the computer system where the module originated. When network access is permitted, the properties of network request can be adjusted so that security information of the client system and the originating computer system for the module are not divulged. Thus, a module can obtain content for inclusion in a Web page from third party servers in a more secure meaner. Network e access decisions can be made based on ambient data already accessible to a host environment such that network access decisions can be made in a more automated manner.

A method for coordinating access to a storage volume between several hosts, each of which has an associated log, may involve: one of the hosts requesting permission from a coordinator to perform a write to a region of the storage volume; the host storing write data for the write to an associated log; and the coordinator sending a response granting permission to perform the write to the host, where the response indicates whether an old version of data in the region of the storage volume should be relocated to a COW (Copy On Write) snapshot volume. The host may signal completion of the write to an application that initiated the write prior to performing the write to the region of the storage volume and subsequent to both storing the write data to the associated log and receiving the response from the coordinator.

This disclosure describes methods and systems for searching documents in a multi-tenant hosting environment. According to embodiments, to conserve hardware resources, a plurality of documents associated with a plurality of tenants may be mapped to the same search index in the multi-tenant hosting environment. In order to search documents associated only with a single tenant in the multi-tenant hosting environment, a tenant identifier is prepended to every key stored in the search index that is associated with the plurality of documents of the single tenant. Moreover, where one document links to another document within the multi-tenant hosting environment, the link is stored in a web graph when a source tenant identifier matches a target tenant identifier for the link. According to embodiments, when conducting a search, the link is resolved only if the link is stored in the web graph.

One embodiment of the present invention provides a system that facilitates single sign-on services in a hosting environment. The system operates by first receiving a request from a user to access a partner application at an application server. The system then determines if the user holds a token granting access to this partner application. If the user does not hold this token, the system redirects the request to a single sign-on server. This single sign-on server requests a user authentication credential from the user. Upon receiving the user authentication credential, including an entity identifier, the single sign-on server verifies if the user is authorized to access the partner application based on the entity identifier. If the user is authorized to access the partner application, the single sign-on server issues a token to the user, which grants the user access to the partner application.

For some of these embodiments, the bypass mechanism operates at a high-level component of the stack or, alternatively, the bypass mechanism operates at a low-level component of the stack.

A method is directed to use of a master root node, in a distributed computer system provided with multiple root nodes, to control the configuration of routings through an I/O switched-fabric. One of the root nodes is designated as the master root node or PCI Configuration Manager (PCM), and is operable to carry out the configuration while each of the other root nodes remains in a quiescent or inactive state. In one useful embodiment pertaining to a system of the above type, that includes multiple root nodes, PCI switches, and PCI adapters available for sharing by different root nodes, a method is provided wherein the master root node is operated to configure routings through the PCI switches. Respective routings are configured between respective root nodes and the PCI adapters, wherein each of the configured routings corresponds to only one of the root nodes. A particular root node is enabled to access each of the PCI adapters that are included in any configured routing that corresponds to the particular root node. At the same time, the master root node writes into a particular root node only the configured routings that correspond to the particular root node. Thus, the particular root node is prevented from accessing an adapter that is not included in its corresponding routings.

A method which simulates the operating speed of an emulated target system with a consistent rate of instruction execution on a plurality of host systems with varied and variable instruction execution speeds. An arbitrary “time quantum” is selected as a referent and is multiplied by the target's speed of instruction cycle execution to determine the quantity of instructions the target system executes in the specified time period. When non-native code is executed on the host system, a counter is used to track the number of instructions executed and to interrupt when that target quantity is reached. A processor-activity-independent timing source is queried to determine the time elapsed; that measurement is then compared to the original “time quantum.” The resulting ratio is a timing reference that is independent of the operating speed characteristics of any particular host system. This reference is used to predict the operational speed of the host system and to adjust factors in the host computer and emulation process to more accurately match the target system before executing the next block of instructions and repeating the process. In certain embodiments, the time quantum is dynamically adjusted to avoid sampling frequencies, which may conflict or resonate with timing frequencies of other system activities or to place a greater or lesser load on the host system. This process results in more consistent, accurate simulation of the target system's speed on a variety of host system configurations, within the limitations and flexibility of the host environment.

Disclosed is a method and computer program device for dynamically managing the assignment of alias addresses to base addresses referencing an input/output (I/O) device, such as a direct access storage device (DASD). Two distinct methods are disclosed. In one method, alias addresses are assigned based on the performance of the I/O devices. In this method, alias addresses are assigned to highly utilized devices, as indicated by device performance data, in order to maximize the efficient utilization of I/O device resources. In a second method, workload management principles are utilized to assign alias addresses. In this method, a correlation is made between each I/O device and the service classes utilizing each device. As in the first method, performance data is generated for each I/O device. Alias addresses are assigned to I/O devices experiencing queue delays as indicated by their performance data, if the device is associated with a service class that has failed to meet one or more processing goals. These methods may operate on a single host, or in a multi-host environment. The methods may be operated individually, or concurrently. Methods are disclosed to manage contention between concurrently operating assignment methods, and between multiple hosts concurrently operating one or more assignment methods.

Some embodiments provide a method of managing cloud resources on several of nodes of a hosting system. The method receives a cloud resource configuration. The method identifies a particular node from the several nodes to host the cloud resource configuration. The method sets an administrative state of the hosting system to reflect the hosting of the cloud resource configuration on the particular node. The administrative state includes information for each node in the hosting system. Each node includes a performer operating on the node that manages an operational state of the node based on the administrative state of the node.

A system and method of booking an itinerary on at least one of a multiplicity of host environments include a plurality of host adaptor modules. Each host adaptor module is configured to interact with one of the plurality of host ticketing environments. A booking engine is provided for receiving commands related to booking the air travel itinerary and determining an appropriate host ticketing environment for processing the commands based on a number of predefined criteria. When the booking engine receives a command it forwards the command to a first host adaptor module which is associated with first host ticketing environment selected by the booking engine for processing the command. The host adaptor module receives the command and issues the command to said first host ticketing environment. The first host adaptor module in turn receives a response from the first host ticketing environment and determines whether the response comports with an expected response. If the response does not comport with the expected response, the booking engine identifies a second appropriate host environment for processing the command and forwards the command to a second host adaptor module associated with the second host ticketing environment. The second host adaptor module then issues the command to the second host ticketing environment.

Systems and methods for designing systems that include computer applications hosted on hosting environments are disclosed. The hosting environments are modeled to include hosting environment settings and constraints placed on applications. The applications are also modeled to include application settings and constraints placed on the hosting environments. Hosting environment and application models are then used to validate designs by confirming that settings are in compliance with the constraints.

A method, mechanism and computer usable medium is provided for distributing I/O fabric errors to the appropriate root nodes in a multi-root environment.

Additionally, a method, mechanism and computer usable medium is provided by which errors detected in an I/O fabric may be routed to all root nodes which may be affected by the error, while not being reported to the root nodes that will not be affected by those errors. In particular, distributed computing system which uses the PCI Express protocol to communicate over the I/O fabric is addressed.

A method and apparatus is provided for routing error messages in a distributed computer system comprising multiple root nodes, and further comprising one or more PCI switches and one or more I/O adapters, wherein each root node includes one or more system images. In one useful embodiment, a method is provided for routing I/O error messages to root nodes respectively associated with the errors contained in the messages. The method includes detecting occurrence of an error at a specified one of the adapters, wherein the error affects one of the system images, and generating an error message at the specified adapter. The method further comprises routing the error message from the specified adapter to the particular root node that includes the affected system image. The error message is then selectively processed at the particular root node, in order to identify the affected system image. Usefully, the step of routing the error message includes using a bus/device/function number associated with the error, together with a routing table located in one of the PCI switches, to route the error message to the correct root node and system image.
