Automated Idle Session Termination in Oracle 10g Using PL/SQL
Managing inactive database sessions is a critical responsibility for Database Administrators (DBAs). In Oracle 10g environments, long-idle sessions can consume server resources, hold locks unintentionally, exhaust process limits, and impact overall database performance. Problem Statement Idle sessions accumulate due to application connection leaks, improper connection pool configuration, users closing applications without logging out, or network interruptions. Manual termination is inefficient in production systems.
