Here's the situation:
I'm trying to get DB2 Connect, running on a linux web server, to connect to a backend DB2 database, running on an iSeries AS400.
I am 100% green when it comes to AS400s and DB2... so keep that in mind.
Here's what I've tried:
- db2inst1@acc-intranet2:~> db2 catalog tcpip node nd1 remote rochester.atlascopco.net server 50000
-
DB20000I The CATALOG TCPIP NODE command completed successfully.
-
DB21056W Directory changes may not be effective until the directory cache is
-
refreshed.
-
-
db2inst1@acc-intranet2:~> db2 catalog database TBIPRODD at node nd1 authentication server
-
-
db2inst1@acc-intranet2:~> db2 connect to TBIPRODD user tbiweb using ********
-
SQL30081N A communication error has been detected. Communication protocol
-
being used: "TCP/IP". Communication API being used: "SOCKETS". Location
-
where the error was detected: "10.48.1.7". Communication function detecting
-
the error: "connect". Protocol specific error code(s): "111", "*", "*".
-
SQLSTATE=08001
Now I figure that error means that it failed to connect via port 50000 (which I read somewhere is the default port). I can't telnet to that port either, so it's definitely not open.
What do I have to do to prepare the AS400 to receive connections from DB2 Connect?
