[oracle@rhel6_lhr ~]$ oerr ora 12162 12162, 00000, "TNS:net service name is incorrectly specified" // *Cause: The connect descriptor corresponding to the net service name in // TNSNAMES.ORA or in the directory server (Oracle Internet Directory) is // incorrectly specified. // *Action: If using local naming make sure there are no syntax errors in // the corresponding connect descriptor in the TNSNAMES.ORA file. If using // directory naming check the information provided through the administration // used for directory naming. [oracle@rhel6_lhr ~]$ 可以确定的是ORA-12162是由于ORACLE_SID未设置或者设置不正确导致的,推荐使用export ORACLE_SID=XXX来设置,当不能设置的时候再用ORACLE_SID=XXX来直接设置。 另外的一篇blog参考:http://blog.itpub.net/26736162/viewspace-1735917/一.4 About Me
