We recently installed zVM 5.3 onto our test VM LPAR (production is still
5.2) and encountered a strange problem in that TCPMAINT appears to be
the only user that can resolve hostnames. OPERATOR, MAINT, other
systems programmer CMS userids all get "Unknown host xxxxxx".
Example:
--- as user: TCPMAINT ---
ping vm03
Ping Level 530: Pinging host VM03 (10.196.76.30).
Enter #CP EXT to interrupt.
PING: Ping #1 response took 0.001 seconds. Successes so far 1.
--- as user: MAINT ------
ping vm03
DTCPIN0014E Unknown host VM03
Ready(00100); T=0.01/0.01 14:43:36
ping 10.196.76.30
Ping Level 530: Pinging host 10.196.76.30.
Enter #CP EXT to interrupt.
PING: Ping #1 response took 0.002 seconds. Successes so far 1.
-------------------------
Has anyone else encountered this issue? We use RACF, but I don't see
any error messages going to RACFVM or OPERATOR, so I don't think it is
RACF related. Plus, when we IPL 5.2 on the test LPAR, it uses the same
RACF database and we don't have this issue.
Any ideas?
Thanks,
