IOAGATE implements DVIPA support using the following channel parameter in the CHANNEL declaration in the ECAPARM member:

BIND={INADDR_ANY|IP_Address|Hostname}

where

• INADDR_ANY indicates that IOAGATE BINDS to any IP address, meaning that it listens to all adapters. Default.
• IP_Address or Hostname indicates that IOAGATE BINDs to either the given IP_address or the IP address after Hostname resolution, respectively.

If the IP address as set in the BIND parameter is defined in the TCP/IP profile as an application-associated DVIPA, the specified IP address is associated with IOAGATE and "follows" IOAGATE when it "fails" on one image and restarts on the other image.

Note: You can use the BIND parameter of the TCP/IP Profile PORT statement to define IOAGATE support for this feature transparently, meaning, without setting the BIND parameter in IOAGATE.
