Which port number is associated with the DB2 service?

• A. 523
• B. 6789
• C. 1194
• D. 5432

Answer: (A)

Databases expose their service through a TCP port that clients connect to, and DB2 uses a dedicated listener to handle those connections. By default, the DB2 listener binds to port 50000, though this can be changed per instance in the TCP/IP configuration. So the most reliable default to remember is 50000 for DB2. If you see other numbers, they belong to different services (for example, 5432 is PostgreSQL, 1194 is OpenVPN), and the actual DB2 port in a given setup should be verified from the DB2 instance’s listener configuration. The key idea is that DB2’s port is set by its listener configuration, with 50000 as the common default.
