Configure the interfaces File for Multiple Networks

On some platforms, SAP ASE can accommodate multiple networks. This allows SAP ASE to listen for clients over multiple network interfaces. You must add an entry for each network interface to the interfaces file.

• Configuring the Server for Multiple Network Handlers
  Configure multiple network listeners.
• Configure Client Connections
  When an SAP ASE client scans the interfaces file for a server name, the client uses the first “query” entry it encounters for the server’s entry. This makes configuring clients to use multiple network connections less straightforward than configuring the server ports.
• Configuring for Query Port Backup
  If a client is connected to a server via two networks, the client can establish a connection via the second network if the first one goes down.
