Hi!
I had a node cataloged with an explict IP-address.
I tried to change to a fully qualified name but:
db2 catalog tcpip node mynode remote db2server.mycompany.biz server 50001
The catalog command was acccepted, db2 was restarted,
but when I tried to connect to a database on that node:
SQL1042C An unexpected system error occurred. SQLSTATE=58004
I then uncataloged and issued
db2 catalog tcpip node mynode remote db2server server 50001
where db2server is registrered in /etc/hosts and it worked OK.
Does DB2 not perform DNS lookup?
The client db2 is V9.1 on Linux and DNS lookups are working for other applications
