Connecting to DB2 database

I get the following error when I try to connect Toad for DB2:

ERROR [08001] [IBM] SQL30081N A communication error has been detected. Communication protocol being used: "TCP/IP". Communication API being used: "SOCKETS". Location where the error was detected: "10.99.13.5". Communication function detecting the error: "recv". Protocol specific error code(s): "", "", "0". SQLSTATE=08001

enter image description here

Attached is my connection properties. Any help connecting would be great.

This is tipical problem when the client cannot reach the database. There could be different reasons:

  • Closed port in the local (client) machine. (firewall outbound)
  • If using local catalog, check if everything is correct (db2 catalog database, db2 catalog tcpip node). If using direct connection skip this step.
  • Routing problem (iptables ou network firewall)
  • Database server with closed port (inbonud) - netstat -nato check port.
  • Instance down (ps -ef or task center in windows)
  • DB2COMM registry variable is not set to tcpip
  • Port number is not correctly mapped to service name (instance configuration, use number instead)
  • Database name is not correct (connect locally in the database server)

You can do a telnet from the Windows (client) machine to the server via telnet

telnet databaseServerIP portNumber

Even, if the db2 server is in the same machine, you can do a localhost telnet in order to see that the instance can receive TCP connections

telnet localhost 50000

Once you can do that successfully, you can connect to the database.
