VIPA and DVIPA support

This subsection describes IOAGATE support for the VIPA (Virtual IP Address) and DVIPA (Dynamic Virtual IP Address) features of the IBM OS/390 or z/OS Communications Server.

Unlike a regular IP address, which is associated with a specific communication adapter, a Virtual IP Address is not associated with a specific adapter and may be transferred from one z/OS image to another.

VIPA and DVIPA have the following flavors:

• VIPA takeover
• Dynamic VIPA for a single application instance
• Dynamic VIPA for multiple application instances with a Sysplex Distributor
