Servers with multiple databases

Using Open Client Library, you can connect to a specific database on a server with multiple databases.

You can run the same program against multiple databases without changing the program itself by putting the shortcut name into the program and merely changing the shortcut definition.

For example, the following interfaces file excerpt defines two servers, live_sales and test_sales:

live_sales
     query tcp ether myhostname 5555
    master tcp ether myhostname 5555
test_sales
     query tcp ether myhostname 7777
    master tcp ether myhostname 7777

Start the server and set up an alias for a particular database. The following command sets live_sales equivalent to salesbase.db:

start_iq -n sales_live <other parameters> -x \ ‘tcpip{port=5555}’ salesbase.db -n live_sales

To connect to the live_sales server:

isql -Udba -Psql -Slive_sales

A server name may only appear once in the interfaces file. Because the connection to Sybase IQ is now based on the database name, the database name must be unique. If all your scripts are set up to work on salesbase database, you will not have to modify them to work with live_sales or test_sales.
