To enable clients to reconnect to the failed over companion, you must add a line to the interfaces file. By default, clients connect to the port listed in the query line of the server entry. If that port is not available (because that server has failed over), the client connects to the server listed in the hafailover line of the server entry. Here is a sample interfaces file for a primary companion named MONEY1 and a secondary companion named PERSONNEL1:
MONEY1 master tcp ether MONEY 9678 query tcp ether MONEY 9678 hafailover PERSONNEL1 PERSONNEL1 master tcp ether PERSONNEL 9679 query tcp ether PERSONNEL 9679
Use dsedit to add entries to the interfaces file. If the interfaces entries already exist, you must modify them to work for failover.
See the Adaptive Server Enterprise Utility Guide for information about dsedit.
