Question

在sqlplus命令提示符下sql查询工作正常，但是当我运行sqldeveloper然后收到以下错误 -

查询： - SELECT COUNT（1）FROM omnix.ngi_antenna_v@nc_mbn_omnix_prod;

错误： -

ORA-12154：TNS：无法解析指定的连接标识符

00000 - “TNS：无法解析指定的连接标识符”

*原因：使用

       a connect identifier, and the connect identifier specified could not

       be resolved into a connect descriptor using one of the naming methods

       configured. For example, if the type of connect identifier used was a

       net service name then the net service name could not be found in a

       naming method repository, or the repository could not be

       located or reached.

*行动：

       - If you are using local naming (TNSNAMES.ORA file):

       - Make sure that "TNSNAMES" is listed as one of the values of the

       NAMES.DIRECTORY_PATH parameter in the Oracle Net profile

       (SQLNET.ORA)

       - Verify that a TNSNAMES.ORA file exists and is in the proper

       directory and is accessible.

       - Check that the net service name used as the connect identifier

       exists in the TNSNAMES.ORA file.

       - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA

       file.  Look for unmatched parentheses or stray characters. Errors

       in a TNSNAMES.ORA file may make it unusable.

       - If you are using directory naming:

       - Verify that "LDAP" is listed as one of the values of the

       NAMES.DIRETORY_PATH parameter in the Oracle Net profile

       (SQLNET.ORA).

       - Verify that the LDAP directory server is up and that it is

       accessible.

       - Verify that the net service name or database name used as the

       connect identifier is configured in the directory.

       - Verify that the default context being used is correct by

       specifying a fully qualified net service name or a full LDAP DN

       as the connect identifier

       - If you are using easy connect naming:

       - Verify that "EZCONNECT" is listed as one of the values of the

       NAMES.DIRETORY_PATH parameter in the Oracle Net profile

       (SQLNET.ORA).

       - Make sure the host, port and service name specified

       are correct.

       - Try enclosing the connect identifier in quote marks.
