Configuring Default Domains for Clients

In environments where the client often requests names from a specific domain, it is appropriate to set a default domain. When a default domain is set in the profile, it is automatically appended to any unqualified net service name or service name. For example, if the default domain is set to us.example.com, sales in the following connect string gets searched as sales.us.example.com:

CONNECT scott/tiger@sales

To specify a default domain:

1. In the navigator pane, expand Oracle Net Configuration > Local > Profile.

2. From the list in the right pane, select Naming.

3. Select the Methods tab.

4. Enter the domain in the Default Domain field.

5. Choose File > Save Network Configuration.

Configuring Encryption

Encryption is the process of disguising a message rendering it unreadable to anyone but the intended recipient.

To configure encryption parameters:

1. In the navigator pane, expand Oracle Net Configuration > Local > Profile.

2. From the list in the right pane, select Oracle Advanced Security.

3. Select the Encryption tab.

4. Select either Client or Server from the Encryption list.

5. Select a value from the Encryption Type list to specify the client or server behavior when negotiating encryption and integrity. The four possible values are as follows:

   Element	Description
   accepted	Service will be active if the other side of the connection specifies either "required" or "requested", and there is a compatible algorithm available on the other side; it will otherwise be inactive.
   rejected	Service must not be active, and the connection will fail if the other side specifies "required".
   requested	Service will be active if the other side of the connection specifies either "accepted", "required", or "requested", and there is a compatible algorithm available on the other side; it will otherwise be inactive.
   required	Service must be active, and the connection will fail if the other side specifies "rejected", or if there is no compatible algorithm on the other side.

6. Enter an encryption seed in the Encryption Seed field: a random string of up to 256 characters. This encryption seed is used with the encryption algorithm you select in the next step.
7. From the Available Methods list, select an encryption algorithm, and then choose the right-arrow (<) button to move it to the Selected Methods list. The order of the methods in the Selected Methods list determines the preferred order for negotiation. The following algorithms are supported by Oracle Advanced Security:

   Element	Description
   RC4_256	256 bit key size
   3DES168	Triple DES with a three-key (168 bit) option
   RC4_128	128 bit key size
   3DES112	Triple DES with a two-key (112 bit) option
   RC4_56	56 bit key size
   DES	Standard 56 bit key size
   RC4_40	40 bit key size
   DES40	40 bit key size

8. Choose File > Save Network Configuration.

Note: All Oracle Advanced Security encryption algorithms and key lengths are available for U.S. domestic use only.

Configuring Listener Addresses

The listener must be configured with one or more protocol addresses. The listener receives connection requests from clients configured with the same addresses.

To configure a protocol address for the listener:

1. In the navigator pane, expand Oracle Net Configuration > Local > Listeners.

2. Select a listener.

3. From the list in the right pane, select Listening Locations .

4. Choose Add Address. A new Address tab appears.

5. Select a protocol, and then enter the appropriate protocol parameter information for the selected protocol.

   When configuring the listener to listen on TCP/IP for Oracle Net clients, you should choose the default port or 1521. If you do not, you must configure the LOCAL_LISTENER parameter in the initialization parameter file and resolve the listener name through a naming method.

6. If the computer has more than one IP address and you want the listener to listen on all available IP addresses, configure TCP/IP or TCP/IP with SSL and enter the host name of the computer in the Host field.

7. Optionally, click Show Advanced to specify settings for specifying the I/O buffer space of send and receive operations of session.

8. Choose File > Save Network Configuration.

For more information about configuring a nondefault port, see Chapter 10, Configuring and Administering the Listener, in the Oracle10i Net Administrator's Guide.

For more information about configuring I/O buffer space, see Chapter 14, Optimizing Performance, in the Oracle10i Net Administrator's Guide.

Configuring Data Integrity

Data integrity checking is the process by which a quantity is calculated based on the contents of a message. The sender of the message calculates the checksum. The value of the checksum is included as part of the message packet. The recipient of the message re-computes the checksum of the message upon receipt. The two checksum values must match if the message is to be considered unaltered during transit.

To configure data integrity:

1. In the navigator pane, expand Oracle Net Configuration > Local > Profile.

2. From the list in the right pane, select Oracle Advanced Security.

3. Select the Integrity tab.

4. Enable client or server data integrity by choosing either the Client or Server checkbox, respectively.

5. Specify how the client and the server will negotiate data integrity. You must select Checksum Levels for both the client and the server. Description of the levels follow:

   Element	Description
   accepted	Service will be active if the other side of the connection specifies either "required" or "requested", and there is a compatible algorithm available on the other side; it will otherwise be inactive.
   rejected	Service must not be active, and the connection will fail if the other side specifies "required".
   requested	Service will be active if the other side of the connection specifies either "accepted", "required", or "requested", and there is a compatible algorithm available on the other side; it will otherwise be inactive.
   required	Service must be active, and the connection will fail if the other side specifies "rejected", or if there is no compatible algorithm on the other side.

6. Choose File > Save Network Configuration.

Configuring Listener Logging and Tracing

You can configure the listener with logging and tracing parameters.

Log information is typically stored in the listener.log file located in $ORACLE_HOME/network/log on UNIX and ORACLE_HOME\network\log on Windows platforms.

Trace information is stored by default in listener.trc, located in $ORACLE_HOME/network/trace on UNIX and ORACLE_HOME\network\trace on Windows platforms.

To enable logging or tracing:

1. In the navigator pane, expand Oracle Net Configuration > Local > Listeners.

2. Select a listener.

3. From the list in the right pane, select General Parameters.

4. Select the Logging & Tracing tab.

5. Adjust the logging and tracing settings as needed.

6. Choose File > Save Network Configuration.

Configuring Password Authentication for the Listener

The listener can be configured with security. This way, privileged operations, such as saving configuration changes or stopping the listener, used from the Listener Control utility will require a password. Oracle Net Manager enables you to set an encrypted password.

To set a password for the listener:

1. In the navigator pane, expand Oracle Net Configuration > Local > Listeners.

2. Select a listener.

3. From the list in the right pane, select General Parameters.

4. Select the Authentication tab.

5. Choose Require a Password for Listener Operations.

6. Enter the password in the Password field, and re-enter it in the Confirm Password field.

7. Choose File > Save Network Configuration.

Configuring Profile Logging and Tracing

The client can be configured for logging and tracing.

Log information is typically stored in the sqlnet.log file located in $ORACLE_HOME/network/log on UNIX and ORACLE_HOME \network\log on Windows platforms.

Trace information is stored by default in sqlnet.trc for the client and svr_pid..trc for the server, located in $ORACLE_HOME/network/trace on UNIX and ORACLE_HOME \network\trace on Windows platforms

To enable logging or tracing:

1. In the navigator pane, expand Oracle Net Configuration > Local > Profile.

2. From the list in the right pane, select General.

3. Select the Logging or Tracing tab.

4. Specify the logging or tracing settings

5. Choose File > Save Network Configuration.
