SOAP/AM Server Persistence

Previous pageReturn to chapter overviewNext page

The SOAP/AM Server includes a "persistence" or hot-standby feature to maximize availability. When you start the server with the '-backupcpu' option, it runs as a NonStop process pair, creating a backup process in the cpu that you specified. See Starting the SOAP/AM Server for information about starting the SOAP/AM Server process. See Server Configuration Summary for the current primary and backup cpu assignments.

 

In the event of a hardware failure in the primary cpu or a software failure, the backup process is activated and begins accepting new requests. However, any existing TCP/IP connections from client applications are terminated. Any outstanding IO operations with application servers are abandoned and any uncommitted TMF transactions are aborted.

 

When a client application detects that its connection to the server has been terminated, it should retry the entire transaction. The backup SOAP/AM Server will be available to accept requests immediately.
