Alternatively, local backup may be a database process, for example, a Polyhedra database, similar to the configuration database. Simultaneously, because central processor 13 is in backup mode, the application and DDL file are also copied to dagasheet on central processor When a service endpoint is assigned to a port, the SEM associated with that port passes the assigned SE number to the port driver for that port using the port PID number associated with the SE number.

Most computer systems are based on inflexible, monolithic software architectures that consist of one massive program or a single image.

In this embodiment, when the SMS determines that the scope of the upgrade requires an upgrade to the configuration database, the master SMS instructs slave SMS e on central processor 13 to perform the upgrade. Typically, the number of line cards and ports on each line card in a computer system is variable but the number of chasses, shelves and slots is fixed. As mentioned above, changes may be automatically saved in persistent storage as they are made in non-persistent memory no automatic downgradeor the user may choose to automatically commit an upgrade after a successful time interval lapses evaluation mode.

Again, because the configuration changes were not saved in persistent storage, when the computer system powers back up, the old configuration will be the one implemented. Multiple instances of applications and device drivers are more dataeheet to manage and require more processor cycles than a single instance of each h564a if an application or device driver fails, only the port those processes are associated with is affected.

In addition, there may be multiple chasses.

If a process fails, it may corrupt memory used by other processes. Such a change is termed an upgrade and requires creating a new monolithic image including the changes and then rebooting the computer to cause it to use the new. For a network device, backup state may include critical information that allows the primary process to quickly re-synchronize. In addition, a configurable fault policy allows users to perform manual overrides to suit their specific requirements and to tailor their policies based on the individual failure scenarios that they are experiencing.

Once spawned, each instantiation of ATM — sends an active database query to search ATM interface table for its corresponding group number and to retrieve associated records. Service is not disrupted on the other ports ports 44 a44 b44 d since vertical stacks, and are unaffected and the applications and drivers within those stacks continue to execute and transmit data.

Computer system 10 includes a distributed name server NS application including a name server process a — n on each board central processor and line card. For example, due to a configuration change initiated by the user of the computer system, service endpoint FIG. Data that is sent by the subscriber processes after the termination of the failed process and prior to the notification of the new process identification number may be lost but the recovery of this data if any may be less problematic than notifying the subscriber processes of the failure and having them hold all transmissions.

Under the software class, subclass indications may include whether the fault or event is a system fault, an exception or related to a specific application, for example, ATM. The termination, re-start or upgrade of an object or process is, therefore, transparent to other processes, with the exception of being notified of new process identification numbers.

The method can further include a step of sending notifications of changes to data stored within the configuration database to a Network Management System NMS database process executing on the computer system to synchronize the NMS database with the configuration database. As a result, there is only a limited connection between the computer system’s software and hardware, which allows for multiple versions of the same application to run on the computer system simultaneously and different types of applications to run simultaneously on the computer system.

As a third example, if a particular application instance repeatedly experiences the same software error but other similar application instances running on different ports do not experience the same error, the slave SRM may determine that it is likely a hardware error.

However, changes to the physical system, for example, adding a new type of board, datashedt require changes to the logical model. DD publishes this name to NS b along with the process identification assigned by the operating system and the name of its service endpoints. Perhaps a zero indicates a value field of 32 bits and a one indicates a value filed of 64 bits. If an ATM application fails and is restarted, it must execute an audit procedure with its corresponding device driver or drivers as well as with other ATM applications since this is a distributed application.

As a result, updates are provided only when necessary i. Service density refers to the proportionality between the net output of a particular device and its gross hardware capability. If the primary instantiation fails, it can be re-started, retrieve its datashdet known dynamic state from the backup instantiation and then initiate an audit procedure as described above to resynchronize with other processes.

Moreover, if multiple instantiations of ATM are running on line card 16 a e. If the evaluation mode is successful, then the SMS may fully implement the change system wide. As one example, one port device driver 43 a — 43 d may be started for each port 44 a — 44 d on line card 16 a. MCD 38 assigns a unique PID to the chassis, each shelf in the chassis, each slot in each shelf, each line card 16 a — 16 n inserted in b5664a slot, and each port on each line card.

After multiple failures by the same process, the fault policy may cause the SRM to take more aggressive measures such as automatic downgrade or fail-over. Current methods provide only sporadic coverage for a narrow set of hard faults.
