Hi there,
the return code 1 means that there's no domain available, as you can see here:
USS Return codes
How Db2 aquires IP and domain is explained here, first paragraph:
https://www.ibm.com/docs/en/db2-for-zos/12?topic=messages-dsnl512i
A gethostbyaddr() call is expecting a domain in return. The ip given by Db2 is probably correct. The problem is that a wrong, or no domain, is given to this call. And the return code is very clear: no domain available.
The most probable cause is that the resolver is not working well. You should look at the TCP.PROFILE and/or the USS configuration.
Hope it helps.
