I am trying to connect to a local DB2 10.5 Express-C server. This is a testing environment so I don't care about security.
I am able to connect to the Command Line Processor (running on Windows), and I changed the configuration settings for AUTHENTICATION=CLIENT and TRUST_ALLCLNTS=YES. I expected to be able to connect without authentication at that point (I restarted the DB2 service), but I still get an error.
When I try to connect without username/password
jdbc:db2://localhost:50000/test
I get the error: com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][t4][10205][11234][4.14.146] Null userid is not supported. ERRORCODE=-4461, SQLSTATE=42815
And when I try to add "bogus" user/password (because I can't figure out how to set or reset credentials), e.g.
jdbc:db2://localhost:50000/test:user=userid;password=password;
I get the error: com.ibm.db2.jcc.am.SqlInvalidAuthorizationSpecException: [jcc][t4][201][11237][4.14.146] Connection authorization failure occurred. Reason: Security mechanism not supported. ERRORCODE=-4214, SQLSTATE=28000
How can I connect using JDBC?
