Conexion between Python and IBM i

I want to connect IBM i using IBM_DB function, but i can´t connect because
don´t recognize the database name in parameter conexion, I use my library.

import ibm_db_dbi

# Set up the connection parameters
dsn =
"DATABASE=eamarco;HOSTNAME=192.168.50.225;PORT=922;PROTOCOL=TCPIPtelnet;UID=username;PWD=password"

# Establish the connection
conn = ibm_db_dbi.connect(dsn)

# Create a cursor object
cursor = conn.cursor()

# Execute a SQL query
query = "SELECT * FROM mytable"
cursor.execute(query)

# Fetch and print the results
results = cursor.fetchall()
for row in results:
print(row)

# Close the cursor and connection
cursor.close()
conn.close()
