I had a hard time connecting to a DB2 server after the remote client was installed. I'm not an expert on DB2, so I decided to notate this for others.
-From a command prompt, export a environment variables needed to run:
-Run DB2 and set the database catalog to the remove connection:
db2 => CATALOG TCPIP NODE UNIQUENODENAME REMOTE 192.168.1.10 SERVER 50000;
-Now, set database name to connect through the new node:
db2 => catalog database mydatabase as mydatabase at node UNIQUENODENAME
-And finally, connect to the database:
db2 => connect to mydatabase user username using password
