IBM z/OS on System z

Connecting from BATCH SQLPLUS on Z/OS to a remote database results in:
ORA-12154: TNS: Could not resolve service name or
ORA-12545: Connect failed because target host or object does not exist
TNSPING also fails with illegal address parameter
sqlplus using the same tnsnames entry from Unix System Services (USS) works.
Everything in the TNSNAMES entry looks correct: parentheses match, port number is correct, host name is correct (can be pinged), sid or service_name is correct.
