When the RSE daemon is started
with IBM® Rational® Developer for System z® using the parameter IVP=IVP, the
listing shows an incorrect host node name for the remote system.
Symptom
The
NODENAME shown in the "host IP address" section of the listing, as
shown in the following example, is incorrect:
-------------------------------------------------------------
host IP address:
-------------------------------------------------------------
hostName=NODENAME
hostAddr=9.42.112.75
bindAddr=9.42.112.75
localAddr=9.42.112.75
Cause
The
host name resolution has failed. This error can have several causes.
Diagnosing
the problem
In a z/OS® UNIX System Services prompt, type
the following command:
hostname -r
If this command
returns the wrong host name, then Rational Developer
for System z does not function
and can return the following error message.
EZZ8342I gethostbyname(NODENAME): Unknown host
Resolving
the problem
- Refer to Appendix B of the IBM Rational Developer for System z Host Configuration Reference.
This appendix explains how to set up TCP/IP and how host name resolution
works.
- If, after you complete the instructions in the Host Configuration
Reference, the problem is not solved, look for the following
line in SYS1.PARMLIB(COMMNDxx):
S EZAZSSI,P=NODENAME
If
this line is present, change NODENAME to the correct host name. You
can use the symbolic value &SYSNAME:S EZAZSSI,P='&SYSNAME.'
