Select the network protocol and options These check boxes specifies what protocol or protocols the ODBC DSN will use to access a network database server. In the adjacent boxes, you may enter communication parameters that establish and tune connections from your client application to a database.
TCP/IP If you want to use ECC_TLS (Certicom) or RSA_TLS encryption for network packets, you must select the TCP/IP protocol to access the network database server.
For example, you could enter the following communication parameters for a TCP/IP connection HOST=my_server;PORT=4563.
Shared memory The shared memory protocol is used for communication between a client and server running under the same operating system on the same machine.
For a TCP/IP example, see “Creating an ODBC Data Source (ODBC Administrator)”.
For more information see the CommLinks connection parameter, and Network communications parameters, in Chapter 4, “Connection and Communication Parameters.”
Liveness timeout A liveness packet is sent across a client/server to confirm that a connection is intact. If the client runs for the liveness timeout period without detecting a liveness packet, the communication will be severed. This parameter works only with network server and TCP/IP communications protocols. The default is 120 seconds.
For more information, see “LivenessTimeout connection parameter [LTO]”.
Idle timeout Set the amount of client idle time before the connection is terminated. If a client runs for the idle timeout period without submitting a request, the connection is severed.
The default client idle time is set by the -ti server option, whose default setting in start_iq is 4400 minutes.
For more information, see “Idle connection parameter [IDLE]”.
Buffer size Set the maximum size of communication packets, in bytes. The default buffer size is 1460.
For more information, see “CommBufferSize connection parameter [CBSize]”.
Select the method for encryption of network packets Allows the encryption of packets transmitted from the client machine over the network.
None Communication packets transmitted from the client are not encrypted. This is the default setting.
Simple Communication packets transmitted from the client are encrypted with simple encryption. Simple encryption is supported on all platforms, as well as on previous versions of Sybase IQ.
TLS Communication packets transmitted from the client are encrypted with ECC_TLS (formerly Certicom) encryption. This is a type of strong encryption. It is only available over the TCP/IP protocol.
Click Edit and complete the TLS Encryption Options screen.
