In my grails application (Grails 2.3.8), apart from grails default GANT, I am using Gradle 1.7 as building tool.
In this app, I have used two databases, which are connected with separate drivers. One is Oracle and other one is IBM DB2.
While starting my app in server, both db connections are working fine, but after sometime (around 1hr) DB2 connection is throwing error like : Connection Closed.
The complete exception stack is as follows :
2014-07-17 08:55:27,860 [http-0.0.0.0-8585-3] ERROR transaction.JDBCTransaction - Could not toggle autocommit
