Hi Krishna, This exception is thrown from IgniteCache.query() method which has nothing to do with persistence store. SQL queries in Ignite are always executed against data that is currently in memory - it never goes to database in this case. And to run queries you need to properly configure indexing.
Here is the documentation page with more information and examples on how to use cache query API: http://apacheignite.readme.io/docs/cache-queries. Let us know if you have more questions. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Connecting-to-Oracle-DB-tp719p722.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
