在oracle weblogic Server中使用JDBC Pool，

Question

I have a question that puzzles me these days. I am using JDBC connection pool in oracle weblogc server for my REST API calls. The package was deployed and was able to handle the incoming requests correctly.

But somehow, after a new request is made, in the db session level, I will get a new session row of "INACTIVE" status, even if I have purposely have the db connection closed in the code. And seems to me, this session will kept for ever. Eventually it kills the pool.

Here is the sample of my code, where "apple" is my connection pool name.

    Connection connection = JDBCConnection.getJDBCConnction(apple);
    Statement stmt = null;
    String query ="select name from user";
    String hosts="";
    try {
        stmt = connection.createStatement();
        ResultSet rs = stmt.executeQuery(query);
        while (rs.next()) {
            name   = rs.getString("name");
        }
    } finally {
        connection.close();
    }

Is there anything extra I need to do ?

Thanks,

Jack

Answer 1

You are likely running into an issue where you are closing the Connection but it does not result in closing the ResultSet or the Statement .

The topic has been explained extensively here and here on SO.
