How To Handle Store Failures Using Write-Behind Caching
(Doc ID 978862.1)
Last updated on JANUARY 30, 2022
Oracle Coherence - Version 3.5.0 to 3.5.3 [Release AS10g] Information in this document applies to any platform.
The following how to shows how to deal with store failures in a write behind scenario. The client performing the write to the cache will not have an exception thrown to it upon failure, so it is incapable of handling the exception. Here we setup a demo showing how a store failure will be requeued and continually re-tried until it has successfully been stored.
Note that the behaviour of the write behind queueing changes in Coherence 3.6 and later, where the <write-requeue-threshold> no longer sets a maximum size for re-queued, and simply determines how frequently information on the size of the queue is reported.
