The existing High Availability (HA) failover feature has been extended to ESQL. It allows you to designate and connect to a second server when a connection to the primary server fails. The implementation is straightforward for the C precompiler.
The command line argument parser reads the -H flag, stores the failover server name, and generates the necessary Ct-Lib statements to implement HA failover., as in the following example:
$SYBASE/bin/cpre -H filename.cp
To use this option, the secondary server must be up
and running and correctly listed in the interfaces file as the HA
failover server.
