Rolling Restart of a Coherence Cluster Causes a Reset of The Expiration Time of the Cache Entries (Doc ID 2249287.1)

Last updated on NOVEMBER 21, 2023

Applies to:

Oracle Coherence - Version 3.7.1 and later
Information in this document applies to any platform.


Coherence cluster is made up of 72 cache servers running on 6 Linux Red Had 6.4 machines, and containing several distributed caches with a configured expiry-delay for their entries (there's several millions of entries), it seems that a rolling restart operation on the whole cluster causes a "reset" of the expiration time of the cache entries, meaning that their expiry-delay restarts elapsing from the time in which the rolling restart is performed, as if all the entries were put in cache at the same time. This causes a MASSIVE eviction of entries (i.e. millions of entries) to happen exactly N days after the rolling restart, where N is the duration (in days) of the configured expiry delay.

All cache entries expire at same time after rolling restart. How to preserve the expiry from before the rolling restart?
