Finding a 404 Error: When you encounter a 404 error, your program will display the text "File Not Found" and exit. This can happen due to various reasons such as incorrect file paths or database connections being disrupted.
- Database Leaks: Database leaks occur when a connection is left open after a query has been executed, leading to performance issues and potential data corruption. To detect leaks in your database, you can use tools like SQL Sentry or DB<>query.
- File System Leaks: File system leaks happen when an external process or thread opens or reads files outside the intended application scope. This can cause the program to consume excessive resources and lead to crashes.
Aging Database Connections: When a database connection is left open, it consumes system resources like CPU, memory, and disk I/O. If not properly managed, these connections can become stale and cause performance issues or even crashes.
- Connection Pooling: Connection pooling is an effective way to manage database connections. By reusing existing connections instead of creating new ones, you can reduce connection overhead and improve overall performance.
- Database Aging: Some databases have a self-tuning mechanism that periodically checks for stale connections. If a connection has been idle for an extended period, it will be automatically closed to free up resources.
