Dear All . Greetings ,
I just run a simple test plan which has a Login page load and an ajax.do . I have run this test plan with 500 Concurrent users . I didn't get any error ( Error % ) in Aggregate graph , But while monitoring the tomcat server , I got the following error few times repeatedly as " Cannot open Connections Caused by: java.sql.SQLException: Io exception: End of TNS data channel " . Why the JMeter didn't catch these error on aggregate graph ?? pls Explain asap . Thanking You With warm regards, Vijayakumar.C
