Phantom TNS entry ... ??

Gee, I've never seen anything like this before.

Make sure I don't have any redirection for tns admin

oracle:mydb$ env|grep -i tns_admin

Make sure I don't have a tnsnames entry for 'xyz'.  Ok, there is one for 'xyzprd', but not simply 'xyz'

oracle:mydb$ grep -i xyz $ORACLE_HOME/network/admin/*
/u01/app/oracle/product/11.2.0.3/dbhome_1/network/admin/tnsnames.ora:xyzprd=
/u01/app/oracle/product/11.2.0.3/dbhome_1/network/admin/tnsnames.ora:   (SID = xyzprd)

And yet, if I tnsping 'xyz', it finds address information from somehwere ...

oracle:mydb$ tnsping xyz
