The Sybase Failover feature is documented in the Adaptive Server Enterprise Using Sybase Failover in a High Availability System guide. This chapter describes steps necessary to configure your Open Client applications to connect to the secondary companion during failover, information that is not included in that document.
DB-Library does not support HA Failover. Embedded SQL™ (ESQL) for C and COBOL supports HA Failover starting with version 12.5.
