1.4.1 Recovering from Errors

If an error occurs with Shunsaku and operations cannot be continued, the administrator must eliminate the cause of the error and restart Shunsaku before operations recommence.

The following diagram shows the flow from an error occurrence to recovery in Shunsaku:

1. Eliminate the cause of the error

   Follow users' directions corresponding with Shunsaku messages (which are output tin the system log (syslog) or the event log of the server where the error occurred) to eliminate the cause of an error.

   

   Refer to the Messages for information on the response to the message.

2. Restart Shunsaku

   Once the cause of the error has been eliminated, execute the shunsysstart command on the target server to restart Shunsaku:

   shunsysstart  -n Shunsaku system name

   Normal operations will automatically recommence once Shunsaku has been restarted.

3. Reallocate search data

   If an error has also occurred with a searcher, operations automatically switch from degradation operations to normal operations when Shunsaku is restarted. However, the search data that was allocated to other searchers as part of the degradation process is not restored to its pre-degradation state. Execute the shundresend command to reallocate search data evenly among searchers:

   Shundresend -s  director identifier

   

   While search data is being reallocated, lookup data cannot be updated using the shundimport command or APIs.
