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

Hi!

The RTFM says about hostname:
"The hostname is the name of the node that is known to the TCP/IP network. The maximum length of the hostname is 255 characters. "
None of the examples has a fully qualified hostname, only simple ones.
On the other hand hostname of maxumum 255 characters imply that a FQ hostname should be possible.
Anyone have it working?
