    Can you email me a text version of your KILL_BLOCKERS script? I’m having trouble with the quotes when I copy/paste from your html blog.

    Hello Miladin,

    please take first my apologies for contacting you as owner of Miladin Modrakovic’s Blog Oraclue blog. As Oracle database professional you will be familiar with the advantages/disadvantages of Oracle tracefile analysis. So there is no need to waste your time with long explanations.

    The company I work for is developing a tool named QueryAdvisor specialized on Oracle tracefile analysis. QueryAdvisor provides more information and allows easier access to tracefile data then TKPROF (alone or in combination with TRCSESS) or even TRCANLZR does.

    We are now looking for DBAs and developers assisting as betatesters. We have chosen this approach to be sure that we will cover a huge amount of different Oracle database configurations (different hardware / releases / patch levels).

    You will receive a free Administrator License without restrictions or further obligations for your participation in our betatest and/or writing an article. To avoid any misunderstanding – this is not a new approach to sell you something. We are talking about a free license in exchange of some of your time and experience – nothing more nothing less. We hope that this is a win win situation for both of us.

    You will find additional information and the possibility to register as betatester at:

    More information how to obtain a free license for writing an article and/or review is available at: http://goo.gl/W2LpF

    If you like to do us a special favor – talk to your colleagues about our betatest and share the link.

    We will take care that you will not be contacted a second time. Sorry for any inconvenience caused and thanks for your time.

    Kind regards

    Hi Miladin

    I tested oracle network encrypted data exposed.
    For your scenario using the oradebug, I found one thing wrong.
    why do you run the “alter user demo identified by demo” script after the oradebug event 10079 trace name context off?

    I think you have to run that “alter user demo identified by demo” statement before the oradebug event 10079 trace name context off.

    Can you please verify that?
