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. Action: - 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 asp.net ora-12154: tns:could not resolve the connect identifier specified 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.

defined in tnsnames.ora. For example, for the following tnsnames.ora entry, the Database attribute value needs to be my_database: my_database = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = my_host)(PORT = 1521)) (CONNECT_DATA = https://docs.oracle.com/cd/B19306_01/server.102/b14219/net12150.htm (SERVER = DEDICATED) (SERVICE_NAME = my_database) ) ) If you are using the Instant Client without a tnsnames.ora file, the Database attribute value needs to be a SQL connect URL rather than a service name: //host:port/service_name where host is the host name or IP address of the Oracle database server, port is the Oracle listener port and service_name is the service name. For example: //my_host:1521/my_database If you http://www.easysoft.com/support/kb/kb00951.html want to use the Instant Client with a tnsnames.ora file, the Database attribute value must specify a tnsnames.ora service name and you need to set and export the TNS_ADMIN environment variable. Set TNS_ADMIN to specify the location of the tnsnames.ora file. For example: TNS_ADMIN = /home/oracle/network/admin export TNS_ADMIN Applies To Products Easysoft ODBC-Oracle Driver Knowledge Base Feedback * Did this content help you?
