Setting enable HA is set to 1 allows you to configure Adaptive Server as a companion server in a high availability subsystem. Adaptive Server use s Sybase’s Failover to interact with the high availability subsystem. You must set enable HA to 1 before you run the installhasvss script (insthasv on Windows NT), which installs the system procedures for Sybase’s Failover.

NoteThe license information and the Run value for enable HA are independent of each other. Whether or not you have a license for Sybase Failover, the Run value and the Config value are set to 1 after you reboot Adaptive Server. And until you have a license, you cannot run Sybase Failover. If you have not installed a valid license, Adaptive Server logs an error message and does not activate the feature. See your Installation Guide for information about installing license keys.

Note that, setting enable HA to 1 does not mean that Adaptive Server is configured to work in a high availability system. You must perform the steps described in Using Sybase Failover in A High Availability System to configure Adaptive Server to be a companion server in a high availability system.

When enable HA is set to 0, you cannot configure for Sybase’s Failover, and you cannot run installhasvss (insthasv on Windows NT).
