Symptoms


In an OFSS based application a huge number of Inactive connection to database  are observed on the Database side and confirmed via netstat output. It keeps increasing, and is way past the max capacity of Datasources configured on the server, even though the WLS console reports that connection count is not more than max capacity at any given time for the DS configured on the server.

 

Changes

 The newer JDBC driver (ojdbc8.jar) defaults to using java net NIO. The prior versions do not.
