title: Oracle JDBC connection : Transaction Isolation Level
body: <p>In my application I am using javax.sql.DataSource to for the org.springframework.jdbc.core.JdbcTemplate instance to connect to <strong>Oracle</strong> Datasource</p>
  
  <p>Now when I inspect the connection parameters for this Oracle connection, I see the <strong><em>trasactionIsolation</em></strong> level property as 2 [attached screenshot]</p>
  
  <p><img src="https://i.stack.imgur.com/Y5f9n.png" alt="enter image description here"></p>
  
  <p>Now what is this <strong>2</strong> value maps to? How can I figure out what is the exact isolation level for transaction out of the mentioned isolation levels in the database.
