    virtual circuit wait on XDB

    user455190

      Hello,

      I'm facing a problem, I can't get behind...

      I've created a PL/SQL Package that generates a HTML page with the package procedure "HTP.PRN" in a Ora11gR2 DB.

      Everything works fine. A client with IE or Firefox can access the HTML page without any problem by calling url
      http://<db-servername>:8080/<DAD>/<Package_Name>.<Procedure_Name>

      But when a second client tries to call the same page, it has to wait for approx a minute until the page will be shown in the browser.

      During this time, I can see in dbconsole, that there is a massive peak for "virtual circuit wait" events. After loading the page in IE
      "virtual circuit waits" run against zero again.

       

      I've tested this now on ORA 11GR2 on a Windows and a Linux box. On both machines, there is the same behavior.

       

      The listener.ora looks like this (on Windows box):
      ---
      # listener.ora Network Configuration File: D:\oracle\product\11.2.0\JAAP\network\admin\listener.ora
      # Generated by Oracle configuration tools.

      SID_LIST_LISTENER =
        (SID_LIST =
          (SID_DESC =
            (SID_NAME = CLRExtProc)
            (ORACLE_HOME = D:\oracle\product\11.2.0\JAAP)
            (PROGRAM = extproc)
            (ENVS = "EXTPROC_DLLS=ONLY:D:\oracle\product\11.2.0\JAAP\bin\oraclr11.dll")
          )
        )

      LISTENER =
        (DESCRIPTION_LIST =
          (DESCRIPTION =
            (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
            (ADDRESS = (PROTOCOL = TCP)(HOST = rrottlaender02.seepex.local)(PORT = 1521))
          )
        )

      ADR_BASE_LISTENER = D:\oracle
      ---

      Any hint, showing me the rigth direction, would be great!

      Thank you in advance...

      Ciao,
      Roland
