title: Compiling Stored Procedure hangs Oracle SQL Developer
body: <p>I am facing an unusual problem in Oracle SQL Developer. When I try to compile a store procedure it hangs up the Oracle SQL DEveloper Screen and I can't do any activity, except to kill the SQL developer instance and start again. </p>
  
  <p>But the same issue. Anybody faced such problem? I am new to oracle.  </p>
  
  <p>Here some additions to the problem I waited for 5 to 10 mins and got this error</p>
  
  <pre><code>ORA-04021 timeout occurred while waiting to lock object
  </code></pre>
  
  <p>But I am the only person working on this instance of Oracle</p>
