Summary
Overview
This session is a live technical troubleshooting session focused on resolving a database connection error during a system test. The instructor guides a participant (Eva) through diagnosing and correcting an incorrect database name in a connection configuration, identifying the issue as a spelling error (“chino con n y doble o con k”).
Topic (Timeline)
1. Diagnostic of Connection Error and Database Name Correction [00:00:00 - 00:01:21]
- The instructor initiates a connection test with participant Eva, observing a failure in the test connection result.
- A specific error message is identified: “desconocida base de datos” (unknown database), indicating the database name is not recognized.
- The instructor guides Eva to check the database name configuration, noting the correct spelling should be “chino” with an “n” and ending in “oo” with a “k” (i.e., “chinook”).
- The instructor confirms the error is purely due to incorrect database name casing/spelling.
- After correcting the name, the test connection succeeds.
- The session concludes with the instructor confirming success and checking if others are experiencing similar issues.
Appendix
Key Principles
- Database connection failures often stem from typos or case-sensitive naming errors.
- Always verify exact spelling, punctuation, and special characters in database names and connection strings.
Tools/Commands Used
- Test Connection functionality (likely within a GUI or CLI tool for database connectivity).
- Details panel to inspect error messages.
Common Pitfalls
- Mis-spelling database names (e.g., “chino” → “chinook”).
- Assuming the system accepts variations in spelling or phonetic approximations.
Next Steps (Implied)
- Verify all other participants’ database connection strings for similar naming errors.
- Standardize database name documentation to prevent recurrence.
