Operation Timeout
Operation Timeout is the maximum time in seconds during which a clustered operation must be completed, otherwise the operation will fail. Default Timeout value is 60 seconds and cannot be less than that. Operation Timeout can be changed in the following ways:
Using NCache Manager
Click on the cache name in Cache Explorer to open cache settings.
Go to Cluster Settings tab.
Change the Operation timeout (sec.).
Right click on the cache name in Cache Explorer and select Apply Configuration option.
Through Config.ncconf
You can specify the operation timeout through config.ncconf as follows:
<cluster topology="partition-replica" op-timeout="120sec" stats-repl-interval="60sec" use-heart-beat="False">
</cluster>
