Error removing object from cache with write behind

Question

We have a cache with a DB for a backing store. The cache has a write-behind delay of about 10 seconds.
We see an error when we:
- Write new object to the cache
- Remove object from cache before it gets written to cachestore (because we're still within the 10 secs and the object has not made it to the db yet).
At first i was thinking "coherence should know if the object is in the db or not, and do the right thing", but i guess that's not the case?

Hi Ron,
The configuration for <local-scheme> allows you to add a cache store but you cannot use write-behind, only write-through.
Presumably you do not want the data to be shared by the different WLS nodes, i.e. if one node puts data in the cache and that is eventually written to a RAC node, that data cannot be seen in the cache by other WLS nodes. Or do you want all the WLS nodes to share the data but just write it to different RAC nodes?
If you use a local-scheme then the data will only be local to that WLS node and not shared.
I can think of a possible way to do what you want but it depends on the answer to the above question.
