Oracle Database Performance Improvement: Using Trustworthy Automatic Database Diagnostic Monitor Technology

The Oracle database is widely acknowledged for its high level of trustworthiness. This paper elucidates the manner in which Oracle DB provides an automated methodology for the identification and optimization of performance issues. The capacity for self -tuning is an essential element in the development of a dependable and trustworthy self -directed database. This paper offers a comprehensive examination of Oracle's self -tuning capabilities, focusing on the Automatic Database Diagnostic Monitor (ADDM) as a prominent automatic tuning solution. The discussion encompasses an overview of these capabilities and a thorough presentation of ADDM's features and functionalities. The ADDM (Automatic Database Diagnostic Monitor) is a tool that systematically evaluates and scrutinizes the data obtained from the Automatic Workload Repository (AWR) in order to detect and assess possible performance concerns within the Oracle Database. To assess the efficacy of ADDM, we formulated a program to replicate substantial server workloads and effectively implemented ADDM suggestions to address the identified issues, thereby ensuring a trustworthy resolution.
