You can set utl_http.set_transfer_timeout value globally or in the database

Hello

We have about 25 web called from many procedures for package services. Lately we are seeing time-out errors more than usual. So we started to add the value of utl_http.set_transfer_timeout to a value greater than the value default 60 seconds before making calls. I was wondering if the time-out value is adjustable to the level of the database or in the world to avoid changing each procedure.

Thanks in advance.

BTW, the package for SYS.utl_http body is wrapped. How could I manage the implementation of the package body when it is wrapped?

You do not replace SYS. UTL_HTTP. So no need to know the wrapped (coded) / private parts of the package.

For example

create or replace package UTL_HTTP as
  .. // copied, pasted and modified from real SYS.UTL_HTTP header
  -- The HTTP protocol versions that can be used in the function begin_request
  HTTP_VERSION_1_0  CONSTANT VARCHAR2(64) := SYS.UTL_HTTP.HTTP_VERSION_1_0;
  HTTP_VERSION_1_1  CONSTANT VARCHAR2(64) := SYS.UTL_HTTP.HTTP_VERSION_1_1;
  ..
  procedure set_proxy(proxy IN VARCHAR2, no_proxy_domains IN VARCHAR2 DEFAULT NULL);
  ..
end;
/

create or replace package body UTL_HTTP as
  .. // wrap calls to the real SYS.UTL_HTTP

  procedure set_proxy(proxy IN VARCHAR2, no_proxy_domains IN VARCHAR2 DEFAULT NULL) is
  begin
    SYS.UTL_HTTP.set_proxy(proxy, no_proxy_domains);
  end;
  ..
begin
  // code SYS.UTL_HTTP default settings here
end;
/

With regard to the authorization DBA. No need.

Assuming that you have a lot of code calling UTL_HTTP in your schema. You just create your UTL_HTTP package that encapsulates calls to the real SYSTEM. UTL_HTTP in your schema.

Scheme code always call you UTL_HTTP - but now she's calling your wrapper UTL_HTTP package. And the package in turn call the real SYS. UTL_HTTP package.

If you have 2 schemas calling UTL_HTTP - then the suggestion is to create a 3rd diagram called CODE_LIB or something. It implements the UTL_HTTP package package. It grants execute rights for 1 and 2 CODE_LIB patterns. UTL_HTTP.

Finally, to make the code in diagrams 1 and 2 call CODE_LIB. UTL_HTTP and not SYS. UTL_HTTP, create synonyms in these patterns, for example
create or replace the synonym UTL_HTTP for CODE_LIB. UTL_HTTP

Concern of the DBA is simply security in this regard. Granting access to relevant application schemas to SYS. UTL_HTTPand allowing these tcp access patterns to the outside world (via network ACL in 11g and later).

  • Is there a way you can set up a printer hp 7520 to analyze the auto size?

    When I scan from the printer or the computer, I either make real and then later crop size or size to scan. When I had my photosmart hp over the printer.

    Although several screensavers just do one thing, some of them can be customized.  For example, '3D text' screen saver allows you to choose the text, the text color, size, etc.

    For most screen savers, just choose one from the drop-down list and then click 'OK' - not the button "settings".

  • You can lock an object (video or photo) in the background of another video?

    I am doing a video with an explosion inside so I had the basic video I recorded on the bottom layer and then put the video of the explosion on top of it. Kind of worked by playing the two videos at the same time, she seems completely wrong, because the explosion remains in the same exact spot regarding the first camera (video I recorded). Then when my camera settles the explosion followed, rather than stay in the same place as in real life. Is it possible to "lock" to a position in the pictures?

    It is best done in things like the first or After Effects. the best you can do with the PS, is to put the clip into a smart object, then you can use move or transform keyframing to move the layer with your another clip. You need to add more keyframes to get to to move convincingly.
