error in coracle Coherence "No storage-enabled nodes exist for service DistributedSessions"

Question

I made java application to load data to distributed Cache. Application load data well but when loading over than 10 million of record, I’ am getting “No storage-enabled nodes exist for service DistributedSessions” error.but when I load less than 10 million it working good. I create one cluster in web logic and join 4 nods as the following:

• 2 servers (Storage enable =true) to store data

• 2 client (Storage enable =false) to view and query only

Answer 1

as much I remember, localstorage=false says to the service to avoid loading data at all, so over 10 M of records, I guess you coherence lacks of memory and cannot load any more data. Try changing your eviction policy as well, but from my point of view, you localstorage might be true. This property is in use on proxies, in order to say them to act or not as servers as well.
