A method and information processing system manage workflow instance migration. A received migration plan indicates a set of workflow migration points associated with an initial workflow process model. The set of workflow migration points is associated with a set of workflow activities of the initial workflow process model. At least one workflow instance is selected from a set of workflow instances. A current migrateability state associated with the selected workflow instance is determined based at least on the set of workflow migration points. Migration of the workflow instance to a new workflow process model is granted in response to determining that the current migrateability state is set to migrateable. Migration of the workflow instance to the new workflow process model is prevented for at least a given amount of time in response to determining that the current migrateability state fails to be set to migrateable.

A mechanism is provided for searching a virtual resource in a large scale computing system environment. The virtual resource is deployed on at least one server. Each server is coupled to a sensor and communicates with the sensor. The sensors communicate with each other and consist of a communication network. Each sensor stores an identifier of a virtual resource deployed in a server connected with the sensor and the location information of the sensor itself. The mechanism receives a searching request for a virtual resource by the at least one sensor, the searching request containing an identifier of the virtual resource being searched; forwards the searching request in the communication network of the sensors; and returns a location information of a sensor storing the identifier of the virtual resource by the sensor itself.

In one embodiment, a method for solution provisioning includes establishing a provisioning task, and obtaining a provisioning image for the provisioning task from a hardware memory. A provisioning implementer is configured based on the obtained provisioning image. The provisioning image comprises configuration information used for executing installation, scripts for executing installation, and information for mapping the configuration information to the scripts. In another embodiment, an apparatus for solution provisioning includes a hardware processor, and a task manager running on the hardware processor. The task manager is configured to establish a provisioning task and obtain a provisioning image for the provisioning task. The task manager configures a provisioning implementer based on the provisioning image obtained. The provisioning image comprises configuration information used for executing installation, scripts for executing installation, and information for mapping the configuration information to the scripts.

In one embodiment, an apparatus for solution provisioning includes a task manager configured to, establish a provisioning task and obtain a provisioning image for the provisioning task in response to a request, and a provisioning implementer configured to execute and monitor the provisioning task established by the task manager. The task manager configures and launches the provisioning implementer based on the provisioning image obtained, and the provisioning image includes configuration information and scripts used for executing installation, and information for mapping the configuration information to the scripts. In another embodiment, a method includes establishing a provisioning task in response to a received solution provisioning request, obtaining a provisioning image for the provisioning task, configuring and launching a provisioning implementer based on the obtained provisioning image, and executing and monitoring the provisioning task using the provisioning implementer. Other systems, methods, and computer program products are described according to other embodiments.

A method, system and computer program product is disclosed for supporting role-based access control in a collaborative environment, wherein pluralities of users work together in a collaborative process using a software system. The method comprises componentizing the software system into a multitude of software components, and limiting access to specific software components to certain users based on roles assigned to the users as defined by a run-time state of the collaborative process. The set of components that a user can access is dynamic, that set can change based on the 'context' or the step where the user is in a collaborative workflow/process. Thus, in comparison with traditional access control mechanisms, an embodiment of the invention combines three different elements: a) the set of components that comprise the application is partitioned in such a way as to make componentized role-based access control feasible, b) a method for specifying inter-component dependencies to enable role-based groups, and c) enabling the modification of the access privileges based on contextual information from a collaborative process.

A method and information processing system manage workflow instance migration. An initial workflow process model is compared with a new workflow process model. A set of differences between the initial workflow process model and the new workflow process model are determined. At least one set of activities associated with the initial workflow process model that is migrateable to the new workflow process model is identified based on the set of differences. A migration plan associated with the initial workflow process model and the new workflow process model is generated. The migration plan includes the at least one set of activities associated with the initial workflow process model. The migration plan is then used to evaluate a set of workflow instances associated with the initial workflow process model and migrate one or more of these workflow instances to the new workflow process model based thereon.

A method for activating a virtual machine, an apparatus for simulating a computing device and a device for supervising activation of the apparatus. The method includes: activating a network interface of the virtual machine, and activating other components of the virtual machine, where the network interface of the virtual machine is capable of communicating with the outside world so activation of the other components of the virtual machine can be supervised. The simulation apparatus includes a network interface and an operating system having a security sub-system, where the network interface is configured to be first activated during activation of the simulation apparatus so the network interface can communicate with the outside world, and activation of the other components of the apparatus can be supervised during the activation of the other components of the apparatus.
