Abstract

According to one general aspect, a method may include acquiring, by a session manager, a list of active sessions. In various embodiments, each session may include a grouped plurality of sub-tasks that are configured to be sequentially performed in order to accomplish a business management task. In some embodiments, the method may include receiving a selection of one of the sessions to supervise. In one embodiment, the method may include retrieving a list of the at least one event listener(s) from a session context associated with the selected session. In another embodiment, the method may include receiving events generated by the session.

wherein the central session manager is configured to provide a single point of access to a central repository for all running and registered sessions of the listed sessions, register at least one of the listed sessions with session execution context, unregister at least one of the listed sessions, return all active sessions of the listed sessions, return at least part of a session context for at least one of the active sessions, maintain a limited number of the active sessions, remove an expired session of the listed sessions when the expired session has an expiration time, unblock a waiting or stalled session of the listed sessions, and monitor one or more of the listed sessions via new listeners;

receiving, at the central session manager, a selection of at least one or more active sessions of the listed sessions to supervise and access to respective session contexts established for the at least one or more active sessions of the listed sessions;

retrieving, at the central session manager, a respective list of event listeners associated with each of the active sessions from the respective session contexts established for the active sessions;

receiving, at the central session manager, events generated by all of the active sessions; and

supervising, at the central session manager, resources for execution of sub-tasks in the selected session according to the received events.

2. The method of claim 1

wherein the plurality of sub-tasks include one or more of manipulation of data associated with physical objects, execution of reports, scheduling activities, manipulation user privileges that dictate what data a user may access/control, and logging information regarding the session.

3. The method of claim 1 wherein receiving a selection of a session to supervise includes:

receiving, from a user, an indication of the selected session;

determining a session identifier associated with the selected session; and

accessing the selected session via the session identifier.

4. The method of claim 1 wherein retrieving a respective list of event listeners associated with each of the active sessions includes:

accessing the respective session context via a session identifier that uniquely identifies the session;

retrieving a list of the at least one event listener from the respective session context;

creating an equivalent event listener to the retrieved event listener; and

associating the created event listener with the session, such that the created event listener receives event notifications regarding the session.

5. The method of claim 1 wherein retrieving a respective list of event listeners associated with each of the active sessions includes:

retrieving a list of one event listener from the session context;

creating an equivalent event listener to the retrieved event listener;

associating the created event listener with the session, such that the created event listener receives event notifications; and

disassociating the session from the retrieved event listener, such that the retrieved event listener no longer receives event notifications regarding the session.

6. The method of claim 1 wherein receiving a selection of one of the sessions to supervise includes:

receiving an indication that the selection is to be controlled by the session manager.

7. The method of claim 1 further comprising:

editing the execution status of at least one of the sub-tasks included in the selected session.

8. The method of claim 1 further comprising:

receiving, by the session manager, a registration notification that a session has been created and is scheduled to be performed by a system that includes a session manger; and

wherein the registration notification includes a session identifier that uniquely identifies the session within the system.

9. An apparatus comprising:

a session lister configured to acquire a list of sessions, wherein each session includes a grouped plurality of sub-tasks that are configured to be sequentially performed in order to accomplish a business management task,

wherein the business management task includes one or more of Enterprise Resource Planning (ERP), Customer Relationship Management (CRM), Supplier Relationship Management (SRM), Product Lifecycle Management (PLM) and Supply Chain Management (SCM) tasks,

wherein one or more event listeners are bound to each session, and wherein each event listener is configured to receive and process event notification messages produced by execution of sub-tasks of the bound session;

a session selector configured to receive a selection of one of the one or more active sessions of the listed sessions to supervise and respective session contexts established for the one or more active sessions of the listed sessions; and

a central session event listener manager configured to;

provide a single point of access to a central repository for all running and registered sessions of the listed sessions, register at least one of the listed sessions with session execution context, unregister at least one of the listed sessions, return all active sessions of the listed sessions, return at least part of a session context for at least one of the active sessions, maintain a limited number of the active sessions, remove an expired session of the listed sessions when the expired session has an expiration time, unblock a waiting or stalled session of the listed sessions, and monitor one or more of the listed sessions via new listeners;

retrieve a respective list of event listeners associated with each of the active sessions from the respective session contexts established for the active sessions; and

receive event information generated by all of the active sessions,

wherein the session lister is configured to update the acquired list of sessions in response to the received event information.

10. The apparatus of claim 9 wherein the plurality of sub-tasks include one or more of manipulation of data associated with physical objects, execution of reports, scheduling activities, manipulation user privileges that dictate what data a user may access/control, and logging information regarding the session.

11. The apparatus of claim 9 wherein the session selector is configured to:

receive, from a user, an indication of the selected session;

determine a session identifier associated with the selected session; and

access the selected session via the session identifier.

12. The apparatus of claim 9 wherein the session event listener manager is configured to:

access the session context via a session identifier that uniquely identifies the selected session;

retrieve a list of one event listener from the session context;

create an equivalent event listener to the retrieved event listener; and

associate the created event listener with the session so that the created event listeners receive event notifications regarding the session.
