Security mechanism not supported. ERRORCODE=-4214

Troubleshooting


Problem

The JDBC Gateway fails to connect to the database. The error in the log file reads: Reason: Security mechanism not supported. ERRORCODE=-4214, SQLSTATE=28000

Cause

The database authentication method needs to be checked.

Environment

JDBC Gateway connecting to DB2.

Resolving The Problem

Check what you have the database authentication set to:

db2 get dbm cfg | grep AUTHENTICATION

If it is correctly set, this value should be SERVER. You can reset it as
follows:

db2 update dbm cfg using authentication server

Please verify this action with your DBA however before applying the
change to the database.
