Clients with DNS name resolution problems may fail to reconnect to an alternate high availability server when the instance to which it is connected fails, producing this message:
Connection to Sybase server has been lost, connection to the next available HA server also failed. All active transactions have been rolled back.
DNS name resolution issues occur when the client’s host cannot correctly resolve a hostname for the alternate instances. To determine if this error is produced by a DNS name resolution problem, issue a ping hostname command for each alternate instance in the high availability list, where hostname is the host on which the alternate servers reside. If the hostname cannot be resolved, or resolves to the wrong IP address, rectify the name resolution issue according to your system administration documentation.
