Connection refused to DB2 ERRORCODE=-4499 during server setup

Troubleshooting


Problem

Attempts to configure your IBM DB2 database connection in IBM Rational Asset Manager results in "Error opening socket to server {machine} on port 60,000 with message: Connection refused. "

Symptom

You see the following error message:

CRRAM703I: Database - [jcc][t4][2043][11550][3.51.90] Exception java.net.ConnectException: Error opening socket to server {machine} on port 60,000 with message: Connection refused. ERRORCODE=-4499, SQLSTATE=08001

Cause

A possible cause for this problem is that TCP/IP is not properly enabled on your DB2 database server.

Resolving The Problem

Use the db2set DB2COMM command from the DB2 command window to start the TCP/IP connection:

db2set DB2COMM=protocol_names


For example, to set the database manager to start connection managers for the TCP/IP communication protocols, enter the following commands:


db2set DB2COMM=tcpip

db2stop

Db2start

If the above command does not resolve the connection problem, contact IBM support.
