TTC_Server or TTC

When connecting to a TimesTen database using the TimesTen client and server, the TimesTen client requires the specification of the network address and TCP port number of the computer running the TimesTen server. The network address provided can be a domain name server (DNS), host name or IP address.

Note:

If you are configuring for client failover, you may define more than one TimesTen server. See TTC_Server2, TTC_ServerN for more information.

If the TimesTen server is listening on a non-default port number, you must provide the port number in one of the following ways:

You can specify the port number within the TTC_Server connection attribute using:
```
TTC_SERVER=server_host_name/server_port;
```

You can specify the port number in the ODBC connection string.

"TTC_SERVER=server_host_name;TTC_SERVER_DSN=Server_DSN;
TCP_PORT=server_port"

Or:

"DSN=Client_DSN;TCP_Port=server_port"

If using TimesTen Classic, you can specify the port number within the logical server definition in the ttconnect.ini file.

See TCP_Port for more details.

Note that:

You can use either TTC_Server or TTC_Server1 for TimesTen Scaleout. If you define the TTC_Server connection attribute, the value is used only for the initial connection.
You can specify a logical server name for the TTC_Server attribute with TimesTen Classic that contains the network address and port number pair in the ttconnect.ini file. Once the logical server name is defined in the ttconnect.ini file, you can use that name as the value for the TTC_Server attribute in a Client DSN definition. Multiple Client DSNs referencing the same computer that is running the TimesTen server can use the same logical server name for the value of the TTC_Server attribute instead of having to specify repeatedly the same network address and port number within each of the Client DSNs. See Creating and Configuring a Logical Server Name on Linux and UNIX in the Oracle TimesTen In-Memory Database Operations Guide for more details.

Required Privilege

No privilege is required to change the value of this attribute.

Usage in TimesTen Scaleout and TimesTen Classic

This attribute is supported in both TimesTen Classic and TimesTen Scaleout.

Setting

Set TTC_Server or TTC_Server1 as follows:
