Abstract

A mechanism is provided for distributing software features (particularly software products having a global portion and a user portion necessary for activating the software products) to client workstations of a network. Each client workstation has a multi-user operating system that may be accessed with different user profiles, each one associated with a corresponding operating context. A distribution package is received in the client workstation; the distribution package includes instructions associated with global activities for the client workstation as a whole or with user activities specific for the single profiles. A distribution agent (running outside the context of a current profile) executes only the global activity and schedules the user activities to be performed when a user next logs onto the workstation. A user agent loaded when the workstation is accessed with a selected profile executes the user activities in the corresponding context.

Claims

1. A method of distributing software features to a computer being accessible with a plurality of different user profiles each one associated with a corresponding operating context, the method including the steps of:

providing a distribution package including at least one item indicative of an activity for enforcing a corresponding software feature on the computer, at least one activity being defined as a user activity associated with at least one user profile,

storing an indication of the at least one user activity on the computer,

accessing the computer with a current user profile, and

retrieving and executing each user activity associated with the current user profile in the corresponding operating context, wherein at least one item includes a flag defining the corresponding activity as a global activity or a generic user activity, the method further including, for each user activity of the at least one item, the steps of;

storing an indication of a completion of the generic user activity for each user profile, and

verifying whether the generic user activity has been completed in the context associated with the current userprofile, the generic user activity being executed in the context associated with the current user profile only if the result of the verification is negative.

2. The method according to claim 1, wherein at least one activity is defined as the global activity associated with all the user profiles, the method further including the steps of:

running a global agent outside the context associated with the current user profile,

executing each global activity under the control of the global agent,

running a user agent during a logon to the computer with the current user profile, each user activity being retrieved and executed under the control of the user agent.

3. The method according to claim 2, wherein the global agent runs on the computer in a logoff condition.

4. The method according to claim 1, further including the steps of:

storing a global memory structure indicating a status of a global portion of each software feature,

storing a user memory structure for each user profile indicating a status of a user portion of each software feature in the corresponding context, and

verifying whether each generic user activity associated with the current user profile has been completed according to a comparison between the global memory structure and the corresponding user memory structure.

5. The method according to claim 1, further including the steps of:

storing an indication of each user profile allowed to have each software feature enforced, and

verifying whether the current user profile is allowed to have the software feature corresponding to each generic user activity enforced;

each generic user activity being executed only if the result of the verification is positive.

6. The method according to claim 1, wherein the computer is a client workstation of a network, the method further including the step of receiving the distribution package on the client workstation from a server workstation through the network.

7. A computer program directly loaded in a working memory of a computer for performing the method of claim 1.

8. A program product including a computer readable storage medium on which the program of claim 7 is stored.

9. The computer program of claim 7, wherein the plurality of different user profiles includes a first user profile for a first user of the computer and a second user profile for a second user of the computer, and wherein the distribution package includes a first item indicative of a first user activity for enforcing a corresponding software feature on the computer for the first user profile and a second item indicative of a second user activity for enforcing a corresponding software feature on the computer for a second user profile.

10. The method of claim 1, wherein the plurality of different user profiles includes a first user profile for a first user of the computer and a second user profile for a second user of the computer, and wherein the distribution package includes a first item indicative of a first user activity for enforcing a corresponding software feature on the computer for the first user profile and a second item indicative of a second user activity for enforcing a corresponding software feature on the computer for a second user profile.

11. The method of claim 10, wherein the first user activity and the second user activity are different.

12. The method of claim 10, wherein the first user activity is to enable a first software product on the computer for the first user profile, the second user activity is to enable a second software product on the computer for the second user profile, and wherein the first software product is not enabled on the computer for the second user profile.

13. A software distribution application for use in a computer being accessible with a plurality of different user profiles each one associated with a corresponding operating context, the software distribution application including a distribution agent for receiving a distribution package including at least one item indicative of an activity for enforcing a corresponding software feature on the computer, at least one activity being defined as a user activity associated with at least one user profile, and for storing an indication of the at least one user activity on the computer, and a user agent for retrieving and executing each user activity associated with a current user profile in the corresponding operating context, wherein at least one item includes a flag defining the corresponding activity as a global activity or a generic user activity and wherein the user agent further:

stores an indication of a completion of the generic user activity for each user profile, and

verifies whether the generic user activity has been completed in the context associated with the current user profile, the generic user activity being executed in the context associated with the current user profile only if the result of the verification is negative.

14. A system for distributing software features to a computer being accessible with a plurality of different user profiles each one associated with a corresponding operating context, the computer including a distribution agent for receiving a distribution package including at least one item indicative of an activity for enforcing a corresponding software feature on the computer, at least one activity being defined as a user activity associated with at least one user profile, and for storing an indication of the at least one user activity on the computer, a logon module for accessing the computer with a current user profile, and a user agent for retrieving and executing each user activity associated with the current user profile in the corresponding operating context, wherein at least one item includes a flag defining the corresponding activity as a global activity or a generic user activity and wherein the user agent further:

stores an indication of a completion of the generic user activity for each user profile, and

verifies whether the generic user activity has been completed in the context associated with the current user profile, the generic user activity being executed in the context associated with the current user profile only if the result of the verification is negative.

15. The system of claim 14, wherein the plurality of different user profiles includes a first user profile for a first user of the computer and a second user profile for a second user of the computer, and wherein the distribution package includes a first item indicative of a first user activity for enforcing a corresponding software feature on the computer for the first user profile and a second item indicative of a second user activity for enforcing a corresponding software feature on the computer for a second user profile.

16. The system of claim 15, wherein the first user activity and the second user activity are different.

17. The system of claim 15, wherein the first user activity is to enable a first software product on the computer for the first user profile, the second user activity is to enable a second software product on the computer for the second user profile, and wherein the first software product is not enabled on the computer for the second user profile.
