The HA agent is written to work with SWIFTAlliance Access versions 5.5, 5.9, 6.0, and 6.2. IBM DCE version 3.2 is not used anymore by SWIFTAlliance Access 5.9 and later, and must only be installed for SWIFTAlliance Access 5.5. SWIFTAlliance AccessTMis a trademark of SWIFT.
The Sun Cluster HA for SWIFTAlliance Access data service provides a mechanism for orderly startup, shutdown, fault monitoring, and automatic failover of the Sun Cluster service. The Sun Cluster components protected by the Sun Cluster HA for SWIFTAlliance Access data service are the following.

By default the HA agent provides a fault monitor for the DCE component only when using the SWIFTAlliance Access 5.5. The fault monitoring for SWIFTAlliance Access is switched off by default. If the SWIFTAlliance Access application fails, the agent will not restart the SWIFTAlliance Access application automatically. This behavior was explicitly requested by SWIFT. It will enable you to operate the application in a way that the probe does not interfere with the normal behavior of some SWIFTAlliance Access features like:
operator manually triggering the SWIFTAlliance Access restart function , for example, to run SWIFTAlliance Access in housekeeping mode.
automatic or scheduled SWIFTAlliance Access restart, for example, to run database backup and other maintenance or end-of-day processes.
any graceful SWIFTAlliance Access restart or recovery, in case of a SWIFTAlliance Access transient local error.
The HA agent provides the start, stop, takeover, and switchover functionality. This means that when a node fails, the other node will automatically start the SWIFTAlliance Access application. The HA agent also provides an option to turn on fault monitoring for SWIFTAlliance Access at registration time. However, this option is not recommended by SWIFT.
