Applies to:Oracle Coherence - Version: 3.7.1 to 184.108.40.206 - Release: AS10g to AS10g
Information in this document applies to any platform.
Here, we might see this attribute taking several hundred megabytes of memory (say x MB data) to store this information for a single coherence data node. So if we have 'y' number of nodes, then each node would use same amount of memory to store this data. This is one dimension of problem.
The other one could be that if we are using a JMX monitoring utility (like JConsole) to view the Coherence JMX metrics. Under the given scenario, all of the data nodes would start sending this attribute (MaxQueryDescription) to the JMX utility and the data could be overwhelming (x*y MB ). It would also use up lot of network bandwidth to transfer x*y MB amount of data to the machine where the monitoring utility is located.
