Improved techniques for managing enterprise applications on mobile devices are described herein. Each enterprise mobile application running on the mobile device has an associated policy through which it interacts with its environment. The policy selectively blocks or allows activities involving the enterprise application in accordance with rules established by the enterprise. Together, the enterprise applications running on the mobile device form a set of managed applications. Managed applications are typically allowed to exchange data with other managed applications, but are blocked from exchanging data with other applications, such as the user's own personal applications. Policies may be defined to manage data sharing, mobile resource management, application specific information, networking and data access solutions, device cloud and transfer, dual mode application software, enterprise app store access, and virtualized application and resources, among other things.

A user's personal computer can be turned into a personal network server for easily sharing personal digital information with other people using a wide variety of devices. There are a variety of alternative ways in which such file sharing on the user's computer can be implemented, such as with a client-side server approach, a hosted server approach, and an automated publish approach. Depending upon a variety of factors, the requested shared data may be intelligently and dynamically transformed to better fit the requesting party's needs. Programming interfaces are available to third parties that allow for access to the shared data and for providing customized instructions on what to do when transforming the data.

An apparatus, program product and method utilize subgroup-specific leader members to exchange group data between group members during the handling of a request to organize members into a group in a clustered computer system, e.g., when handling a membership change operation such as a merge or join. Such subgroup leaders may be determined locally within individual subgroup members, and moreover, the subgroup members may locally track the transmission status of group data for the various subgroups. Each subgroup includes one or more members that are known to store group data that is coherent among all subgroup members.

The Virtual Machine is viewed by many as inherently insecure despite all the efforts to improve its security. This invention provides methods, apparatus, and computer products to implement a system that provides operating system style protection for code. Although applicable to many language systems, the invention is described for a system employing the Java language. Hardware protection domains are used to separate Java classes, provide access control on cross domain method invocations, efficient data sharing between protection domains, and memory and CPU resource control. Apart from the performance impact, these security measures are all transparent to the Java programs, even when a subclass is in one domain and its superclass is in another, when they do not violate the policy. To reduce the performance impact, classes are grouped and shared between protection domains and map data lazily as it is being shared. The system has been implemented on top of the Paramecium operating system used as an example of an extensible operating system application.

A client is permitted to send data access commands directly to network data storage of a network file server after obtaining a lock on at least a portion of the file and obtaining metadata indicating storage locations for the data in the data storage.
