Abstract
A TMN system includes a multi-threaded persistent TMN agent and Management Information Bases (MIBs), each including a Managed Object Instance Cache The MIB is maintained in a general purpose database system in secondary storage such as a hard disk and not by a TMN agent in main memory. At run-time, incoming TMN manager operations are translated into Database Data Manipulation Language (DML, e.g. SQL DML) commands. The MIB to database mapping supports any database language. The agent process can terminate due to a system failure or other abnormal event. In such a case the object instances and their data, stored in the MIB, are saved in secondary cache memory so that they are not lost. The restarted managed agent process reflects the MIB state of the terminated managed agent process. The managed agent process allows “Multi-threaded” means or parallel processing of messages, including CMIP requests, received from manager processes.
