一.3  总结

[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。
