SQLCODE=-30081 无法使用 python 连接到 IBM DB2 数据库

Question

I am able to connect to DB2 just fine with my TOAD application however I need to be able to connect within python to build some automated reports.

I have installed the ibm_db library and I am trying to follow the instructions but I keep getting error SQLCODE=-30081 .

import ibm_db

conn_str = 'database=XXXX;hostname=XXXX.host.com;port=11111;protocol=tcpip;uid=user;pwd=password'
conn = ibm_db_conn = ibm_db.connect(conn_str,'','')

Traceback:

Traceback (most recent call last):
  File "C:/Users/username/PycharmProjects/Report/MAIN/MAIN.py", line 4, in <module>
    conn = ibm_db_conn = ibm_db.connect(conn_str,'','')
 SQLCODE=-30081

Looking up -30081 is not very helpful as it can be caused by a list of things.

I did read somewhere that maybe ibm_db is only supported on Python 3.4 and I am using Python 3.6 however I cannot install Python 3.4 on my work PC right now as its admin locked.

Update:

Tested connection using the command line with the 2 different connections options available to ibm_db.

Both connections types:

import ibm_db


conn_str = 'database=XXXX;hostname=111.111.111.111;port=11111;protocol=tcpip;uid=username;pwd=password'

try:
    conn = ibm_db.connect(conn_str, '', '')
except:
    print("no connection:", ibm_db.conn_errormsg())
else:
    print("The 1st connection was successful")

try:
    conn = ibm_db.connect('XXXX', 'username', 'password')
except:
    print("no connection:", ibm_db.conn_errormsg())
else:
    print("The 2nd connection was successful")

Error:

Any guidance would be appreciated.
