1.2 Detecting Errors and Assessing the Impact on Operations

If an error occurs with any of the Shunsaku processes (conductor, directors, searchers, or sorters) during operations, a message that a Shunsaku error has occurred is output to the system log (syslog) or event log on the server where the faulty process is located.

Depending on the error, operations may not be able to continue. The following table shows the impact of different errors on operations:

Message ID	Cause	Degree of impact on operations	Impact on active applications
			Connection	Transaction
shn06000u shn06002u	The conductor has not terminated correctly.	Applications cannot connect to Shunsaku until Shunsaku is restored	Disconnected	-
shn02003u shn02012u shn30302u	A director has not terminated correctly.	Searches and updates cannot be performed on Shunsaku until the director is restored.	-	Cancelled
shn02000e	An error has occurred with communication processing for searchers.	Degradation of failover will start automatically, and operations can recommence on completion. Note, however, that if degradation has occurred, it will not be possible to achieve the same level of performance as before the error.	-	Cancelled
shn07015u	A sorter has not terminated correctly.	Data cannot be sorted or aggregated until Shunsaku is restored.	No effect	No effect
