Path validation: ensure it is placed in \drivers .

A transient connection problem (e.g., a brief network hiccup) can be overcome with exponential backoff retries. For example, use Spring Retry or Resilience4j. Path validation: ensure it is placed in \drivers

While authentication failures usually produce a different error (like "Login failed for user..."), sometimes a mismatch in authentication protocols (e.g., the server requires SSL but the connection string does not specify it) can cause a generic connection establishment failure. : For users with non-English locale settings, Cognos

A: Intermittent failures point to network instability, connection pool exhaustion (connections not released), or the database server hitting resource limits (memory, CPU, file handles). Enable more logging and monitor during the failure window. Comprehensive Troubleshooting Architecture
