    IdleRemover notifying pools, interval: 450000

    karhatsu Newbie

      Hello

      Could anyone tell me what the following debug text means?

      DEBUG [org.jboss.resource.connectionmanager.IdleRemover] run: IdleRemover notifying pools, interval: 450000


      What is IdleRemover? What are these pools? Is it something that I should worry about or just normal JBoss activity?

      The text is printed every 10-60 minutes to the log file.

          Hi
          I am facing the same problem, can someone help to fix it. Due to this the servlet requests are denied the access to database.

          Please help

            This is normal. In JBoss/JCA the IdleRemover runs asynchoronously and cleans up connections that have not been used reducing resource usage when it is not required. The message is informational only.

              Yes I agree , its just the message that all the resources are freed up.In my application I have been connecting to database thru' servlets.But as the resources are freed up, everyday in the morning, when my run my application, I get the java.lang.IllegalStateException and on refresh I get the result as desired. After this the application runs fine whole day, but the same story following day.

              I close all the database connections after retrieving the data. So Can someone please help. Its urgent....

              Thanks in advance.

                I am not sure what the IllegalStateException is, or why it is being thrown. JBoss/JCA would not throw this in the case that a connection cannot be used. Easiest thing to do would be to get a stacktrace/logs etc when the error occurs and post it.

                      I get the same message.

                       

                      I'm able to control the repetition of this message in the server log. If I keep my idle-timeout interval in data source as 15 minutes, I get "IdleRemover notifying pools, interval: 450000". However, when i change idle-timeout to 1 minute, the message changes to "IdleRemover notifying pools, interval: 3000"
