摘要： A system and method for using a management interface such as Portable Management Interface (PMI) in a thread-safe and efficient manner. A secondary scheduler receives PMI management requests from multi-threaded manager applications in a thread-safe manner, such as through a lock. The secondary scheduler monitors the flow of PMI-related requests into PMI to ensure that, at any point in time, only one management request (e.g., callback function) is running on the PMI thread. When a request in the secondary queue is ready for scheduling with the primary scheduler, the secondary scheduler then accesses the primary scheduler in a thread-safe manner, such as through a lock, to send the request to the primary scheduler. The management requests are dispatched from the primary scheduler and executed on managed objects though a Management Information Server. The performance and efficiency of the manager applications is enhanced by increasing the responsiveness of interaction between the manager applications and the schedulers. The performance of the management interface is enhanced by eliminating the need for polling-based scheduling solutions.

摘要： A system and method for a synchronous task scheduler. The synchronous task scheduler may be used with a CORBA Gateway between CORBA-based client manager applications and an enterprise manager. The CORBA Gateway may include components such as an Event Gateway which manages events from managed objects, and a Request Gateway which manages requests and responses of managed objects. The Event Gateway and the Request Gateway may be designed as multi-threaded systems. A thread pool may be used to increase efficiency and performance of the CORBA Gateway. To ensure ordered delivery of events or replies to the CORBA gateway clients in a multi-threaded environment using a thread pool, a synchronous task scheduler may be used. There may be a synchronous task scheduler associated with each client manager to preserve the chronology of messages sent to each. The synchronous task scheduler may maintain an internal message list, and deliver one message at a time from that internal list. The synchronous task scheduler may hold a reference to a thread pool and use that thread pool to deliver messages. When a message is scheduled, the synchronous task scheduler may check if any message is already being delivered. If no prior message is currently being delivered, an available thread may be assigned from the thread pool for delivery of the message and the scheduler may initiate delivery of the message. If a prior message is being delivered, it may enqueue the message in the message list. Then, when the prior message delivery is completed, the scheduler may dequeue the message, assign another thread from the thread pool, and initiate delivery of the message. This may continue until the message list is empty.

摘要： A CORBA Gateway between CORBA-based applications and an enterprise manager may be configurable to manage various networked objects, such as printers, scanners, copiers, telephone systems, etc., which may be interconnected via networks. CORBA-based manager applications may communicate managed object-related messages, such as events, requests, and responses, with the managed objects through a CORBA Object Request Broker (ORB). The CORBA gateway may translate the manager requests from IDL to PMI requests. Similarly, the CORBA gateway may translate the enterprise manager PMI responses and PMI events to IDL/IIOP responses and events which may be passed on through the CORBA ORB to the manager applications in the form of IDL responses and CORBA events. In some embodiments, the client may choose the format in which to send and receive message information. To provide text based events, requests, and replies, an extension IDL interface may be used.

摘要： A thread-safe debugging system and method including a thread-safe debug service library and a thread-safe remote control library residing on at least one client computer system. The client and server libraries provide APIs which allow multi-threaded applications executing on the client computer system to take advantage of debug services in a thread-safe and dynamic manner. The remote control library provides third party applications the capability to initiate and manage the debug services on the client dynamically and remotely. The debug services may include providing debug output, listing the one or more debug objects in the multi-threaded application, listing the state of each debug object, turning on or off any debug object by name or pattern, directing the debug output to a remote location, allowing multiple remote diagnostic applications to view the debug output of the application, and logging statistical or performance information. The debug print function provides debug output for one or more threads of the multi-threaded application such that the debug output of each thread remains distinct from the debug output of the other threads. Thread safety may be ensured through the use of thread-safe mechanisms such as locks.

摘要： A system and method for generic and dynamic mapping of managed object metadata. The data to be mapped may include type information about an attribute, action, or notification of a managed object. The first data type is entered into the mapping system, and then a corresponding second data type is determined and returned. In this manner, data types related to the attributes, events, or other parameters of managed objects are converted between various data description languages, such as OMG IDL and ASN1. A single interface is defined to describe substantially all data types and all managed objects. Having a single object interface for all TMN managed objects saves significant resources in that there is no need to statically compile and store separate interfaces for the many objects, which may increase the scalability of a network management system dramatically.

摘要： A gateway between client manager applications and an enterprise manager may be provided to manage various networked objects. In one embodiment, CORBA-based TMN manager applications may be communicatively coupled to a CORBA Object Request Broker (ORB) and may be operable to send Interface Definition Language (IDL) requests to, and receive IDL responses and CORBA events from, managed objects through the CORBA ORB. The client manager may first be authenticated to the gateway by username and password, or other validation information associated with the client manager, which may be represented in a user profile. Once the initial client authentication is accomplished, the gateway may provide object-level access control between manager applications and managed objects at an individual object level so that one of the managers is granted access to one of the managed objects while being prevented from interfacing with a different one of the managed objects.

摘要： A CORBA Gateway between CORBA-based applications and an enterprise manager may be configurable to manage various networked objects, such as printers, scanners, copiers, telephone systems, cell phones, phone systems, faxes, routers, switches, etc., which may be interconnected via networks. Various embodiments of the CORBA Gateway may include an Event Gateway which manages object events. The CORBA Event Gateway is designed to leverage existing Event Distribution Server (EDS) sinks to provide EDS filtering functionality and EDS object level access control functionality. The approach leverages existing EDS solutions by providing a common sink for all events/notifications and using a unique Event Port Registry to manage the subscriptions of various TMN clients that subscribe for such events/notifications. Generally, the approach described provides the capability to filter events according to criteria presented by client event subscriptions. In one embodiment, the events may be filtered to enforce policy-based access control on TMN events/notifications, determining which CORBA client applications have access to which events. The filtering of events at the sink based upon client subscriptions decreases unnecessary network traffic in that events may be “pushed” to the client, rather than delivered upon client request. In addition, the approach may provide easy-to-use IDL APIs that allow CORBA clients to directly subscribe/unsubscribe to events based on criteria such as object class, object instance, and event type.

摘要： A system and method for managing network devices using a metadata gateway. The metadata gateway provides translation of metadata to and from a database format and Interface Definition Language (IDL), which is operable across a plurality of platforms and across a plurality of programming languages. Metadata may be retrieved through the metadata gateway by a client manager application sending a request for type information for a managed object attribute or event in IDL through a CORBA Object Request Broker (ORB) to the metadata gateway, which then reads the type information from a metadata repository, where the type information is stored in a database format. The metadata gateway then translates the retrieved type information from the database format to IDL and sends the translated type information to the ORB, which sends the translated type information for the attribute or event to the client manager application. Metadata may be encoded through the metadata gateway by sending the metadata in IDL to the metadata gateway, which translates the type information from IDL to a database format and stores the type information in the metadata repository.
