Want to see the nickname setup for a DB2 database?  Here’s a handy query…

SELECT 
        NICK.TABSCHEMA,
        NICK.TABNAME,
        NICK.SERVERNAME,
        NICK.OWNER,
        NICK.REMOTE_SCHEMA,
        NICK.REMOTE_TABLE,
        SRV.SERVERTYPE
FROM    SYSCAT.NICKNAMES NICK
        INNER JOIN SYSCAT.SERVERS SRV
            ON (NICK.SERVERNAME = SRV.SERVERNAME);
