| Question ID 21411 | Oracle resolves service names to connection strings by using several methods. One of these methods is host
naming. Which statement defines this method?
|
| Option A | Host naming method uses tnsnames.ora file to lookup service names.
|
| Option B | Host naming method uses Oracle names, which maintains the central storage of network services.
|
| Option C | The host naming method uses the third party name resolution mechanisms that can integrate with Oracle.
|
| Option D | The host naming method uses the name of the machine to establish the connection instead of the
tnsnames.ora file.
|
| Correct Answer | D |
Explanation Explanation: Answer D is correct. The host naming method uses the name of the machine to establish the connection instead of the tnsnames.ora file or Names server. Net8 makes it possible to configure you client so that you don't need to rely on locally configured client tnsnames.ora files or Oracle Names servers to connect those clients to the Oracle server. Instead, Net8 offers a feature called host naming. This feature takes advantage of any naming services that are already available on the network to identify the machine that hosts Oracle to the client. Once a connection with that machine is established, Net8 client attempts to connect to the Net8 server using the established methods for Oracle connections. In TCP/IP, which is the environment where host naming can be used, this consist of the Net8 client attempting to locate the listener on the well-known port an Oracle listener listens on, 1521. Incorrect Answers: A is incorrect; host naming method does not use tnsnames.ora file to lookup service names. B is incorrect; host naming method does not use Oracle Names server. C is incorrect; host naming method does not use the third party name resolution mechanisms
| Question ID 21412 | Which two parameters need to be configured in the tnsnames.ora file to utilize the connection concentration
feature of Connection Manager? (Choose two)
|
| Option A | CMAN
|
| Option B | CMAN_RULES
|
| Option C | Address for the Connection Manager process.
|
| Option D | Address for the database dispatcher process.
|
| Option E | Address for the listener on the destination node.
|
| Correct Answer | C,E |
Explanation Explanation: Answers C and E are correct. To utilize the connection concentration feature of Connection Manager address for the Connection Manager process and address for the listener on the destination node need to be configured in the tnsnames.ora file. Incorrect Answers: A is incorrect; there is no CMAN parameter in the tnsnames.ora file. This parameter is present in the cman.ora file. B is incorrect; there is no CMAN_RULES parameter in the tnsnames.ora file. This parameter is present in the cman.ora file. D is incorrect; address for the database dispatcher process does not need to be configured to utilize the connection concentration feature of Connection Manager.
