Timeout in Oracle 11 g - UTL_HTTP.set_transfer_timeout Scnearios

Hi friends,

When we use the UTL_HTTP.set_transfer_timeout (180);

How to handle the situation after the timeout, for example, if the web service has not responded for more than 180 seconds.

Then, we should handle this.

in my requirement.

We should get the timeout error; and insert it into a table of logging sepearte error message.

can you help me please on this

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).

The requests hung and implementation Oracle driver thin query timeout
We are seeing occasional cases of threads blocked, where the code is in Oracle thin XA of the code driver waiting for a socket read a response from the database. Usually only one thread at a time. The connection is never ending and we close WebLogic to clear it. DBA tells us that all connections for the RAC 11 g of our guests cluster members are inactive, with no hanging transactions or long term.

In this case every few cases of days between two WebLogic 10.3.5 grouped in our QA environment, is generally not the same time on both servers (we had four incidents, the other had one, in the last 15 days). Sometimes it resulted in a server hung, the driver is keeps a lock that is blocking other threads (today we had many discussions block in a restoration of TX).

I'm guessing that our instance of WebLogic somehow does not receive the close connection of the remote host. BTW, there is no firewall between us and the DB. I don't have any suspect strong for the cause (even if we're under Linux on a virtual VMWare 4.0 computer, always worried).

Usually, I would ask any application to set a timeout for the query or set the time-out request to connect with Betclic to work around the problem (we use a MultiDatasource), if the transaction will give up at least and the application can manage it. However, while the Oracle driver supports java.sql.Statement.setQueryTimeout (), a brief investigation on my part leads me to believe the time-out is implemented on the server side, not client side - so that if it is indeed the case that WebLogic does not see the outcome on the connection, it also would never see the timeout.

Two questions:
1. is my suspicion implementation timeout for Oracle 11 g correct server-side?
2. If so, is there a property that I can put to the pilot who will implement a socket timeout? It is "safe"?

Thanks for any help!

Hi, Yes, there is a property, you can give the driver to taken all calls with a timeout of read.
oracle.net.READ_TIMEOUT. The units are in milliseconds, so choose a high number
enough that no reading legitimate, as a wait for the DBMS do an update or commit.
etc., would take more time.

Help with utl_http and https API

Hi all
I am trying to write a pl/sql procedure to call the google translate API. I paid for a key and the url itself works without any problem, but I'm fighting to get my call from pl/sql.

I created a function on my server as suggested by Billy Verreynne here: Re: error on HTTPS using UTL_HTTP

It was extremely helpful as I can now see the url that goes to google.

This is the code I use to call the function of Billy is:

set serveroutput ON
select * from TABLE(webbrowser('https://www.googleapis.com/language/translate/v2?key=mykeyblahblah&q=Automobile&source=en&target=ja'));

(1) my first question: Why am I get invited to enter variable bind by sqldeveloper? These are hard-coded in the url, I'm passing, so I don't know why I get invited to these.

By Billy function, which is getting sent to google:

HTTP: GET https://www.googleapis.com/language/translate/v2?key=mykeyblahblahAutomobile=Automobileen=enja=ja

I'm getting ORA-29268: error the client HTTP 400 - Bad request, obviously from the url get passed to google makes no sense, i.e. the ampersands are get and removed the bind variable I entered replace the names of the parameters.

(2) so my second question, what am I doing wrong and how can I get the URL to keep signs and identifiers in parameters?

The first thing that is obvious is that I have a lot to learn here. There seems to be that many tutorials online to UTL_HTTP and even the docs of Oracle are a little sparse.

For what it's worth my portfolio is ok and the proxy are set that correctly, so I know I'm getting to google, I'm just passing through a bad url.

This isn't the last function, I'm just trying to take the baby steps so I just call the pl/sql API and retrieve a readable result. If anyone can help point me in the right direction, I would be very grateful.

If it helps, here's the function I created using the code of Billy:

John K. says:

(1) my first question: Why am I get invited to enter variable bind by sqldeveloper? These are hard-coded in the url, I'm passing, so I don't know why I get invited to these.

No bind variable. As bathtubs say these are substitution variables. Something that SQL * more supported for several year and something that is incorporated as a feature of some GUI for Oracle customers.

Substitution variables are generally used in the installation scripts. You run a script (since SQL * the command-line) and passes command line parameter - these parameters are variables + & 1 + for the parameter 1, + & 2 + for the 2nd, etc..

The script can then use these in the DDL statements (that do not support the bind variable) - e.g. create user & 1 identified by & 2....

The customer to DEFINE in SQL command * more active/disable/configure the use of substitution variables. The default character to identify the variable substitution is "+ & +". So your problem with the URL being mutilated by your customer.

I always use SET DEFINE OFF to disable the calendering customer my sending code on the server for execution. Another option is to use a different character to identify the substitution variables. The installation script Oracle Apex (quite large and quite complex) has the problem of the use of '&' in the code and need to also use substitution variables, as. So the installation uses the "+ ^ + ' character. I suggest to disable the substitution, or affecting a unusual as tank ' ^ ' or ' ~ '.

However, if there are any German character in SAP, then they are replaced by UNWANTED data when they come to Oracle.

If I invoke continues the same web service tools like SOAP-UI, then German characters do very well. I've also drawn web service queries and answers of the side SAP, and there response shows fine. When it comes to Oracle, they are themselves corrupt.

I'm sure it's something to do with the character, but I am not able to find where and what should I fix/change.

Thank you for your help in advance.

I'm not really experienced with utl_http, but maybe you'll read on SET_BODY_CHARSET in the documentation.
ISO-8859-1 is the default characterset, until you specify the characters in the attribute content_type and text media.
But your media type is not text, then perhaps affecting the body charset UTF - 8 can help.

concerning

Utl_http.READ_TEXT hung up
I have the next request to a web service from a pl/sql procedure:
My problem is, the answer is too large and the procedures attached to the line of the utl_http.read_text (see below) statement.
I wrote a log file in the loop and looped several times, and then hung up.

There would be another way to do it?... I have Oracle 11 GR 2.

Thank you.. !!!

How did respval defined in the code?

That it works web remote service correctly when it is called with other tools (soapUI or whatever you prefer)?

It works with smaller answers?

What is returned when you did the logging? It stops at a certain size?

Tjank you!

Generate a model for POST UTL_HTTP, of the w.

I suggest using the free version of SoapUI for this. Very simple. Create the new project of REST. Enter w location (URL). Generates a sample call and look at how the HTML call is formatted. You can also trigger test POST CALL using SoapUI. When it works, copy - paste this MESSAGE template for use in PL/SQL

From what you have posted, it seems to be an error in user code. So if you can get the details of the correct POSITION, the user code should work.

How to manage the response of utl_http
Hello
I use the code to call a https using the POST method below

Utl_http.set_Proxy (apex_application.g_proxy_server, NULL);
Utl_http.set_persistent_conn_support (true);
Utl_http.set_transfer_timeout (300);
Utl_http.set_wallet (p_wallet, p_wallet_pwd);
l_http_req: = utl_http.begin_request (p_api_url, 'POST');
Utl_http.set_header (l_http_req, "Proxy-Connection ',' Keep-Alive'");
Utl_http.set_header ("l_http_req, 'Content-Type', ' application/x-www-formulaires-urlencoded; charset = utf-8 ');
Utl_http.set_header (l_http_req, "Content-Length", length (l_post) ");
Utl_http.write_text (l_http_req, l_post);
l_http_resp: = utl_http.get_response (l_http_req);
Utl_http.READ_TEXT (l_http_resp, l_response);

The return url a respose with sub content l_response
< html >
< head >
< META HTTP-EQUIV = "content-type" CONTENT = text/html"; charset = UTF8' >
< / head >
< title > payment Page < /title >

< are method = "POST" name = "online payment" action = "http://www.testing.com" >

< / make >

< script language = "JavaScript" >
document.ePayment.submit ();
< /script >

< / html >

Apparently it will redirect to http://www.testing.com,
How my procedure should handle this response then it will redirect to the url?

Thank you.

Try the following

Save the contents of the "l_response content" in a page/app-item.
Create a new page with a region of dynamic pl/sql code with the following code
```
htp.p(:l_response_app_item);
```
Create a branch on the execution of the call to UTL_HTTP page' to branch to the new created page as above

When the new page loads, it must submit automatically to http://www.testing.com.

How to get GMT or IST using the PL/SQL FUNCTION
Hello, I use Oracle 10 G database (operating system: Windows-32 or 64 Windows).
How can I get the date and time GMT or International without mentioning SYSDATE / DBDATE.
Real problem the DB Sever time is frequently manipulated by the end user and I would like to connect the actual date and time of the transaction in other audit tables.

Kind regards

Tarun
It won't increase your load on the server, you would simply have many waiting http events and the performance of your application depends on your internet connection to customers. Something not very desirable if you ask me and certainly will cause you headaches. Really bad headaches, and one day someone will ask who came up with the brilliant idea to get the timestamp system via http instead of... + sysdate + (I smell a future article http://thedailywtf.com/).

In any case; That is: the http based sysdate function. I use mod_plsql to my 'webservice' running on a server where I'm sure the date is correct. You can use what you want, for a 'real' webservice implementation will be a little different. Google should know the answer about calling Web services from the data base.
```
$[CHE_TEST@asterix1_impl] create or replace procedure server_time as
  2  begin
  3  htp.print(to_char(sysdate, 'dd.mm.yyyy hh24:mi:ss'));
  4  end;
  5  /

Procedure created.
```
As you can see the procedure does nothing else then exit the sysdate from my database server in a specified date format. I then call the procedure mod_plsql via utl_http on another server:
```
$[CHE_TEST@asterix2_al32utf8] create or replace function get_server_time return date is
  2  begin
  3    --default would be 60, this is clearly too much
  4    utl_http.set_transfer_timeout(1);
  5    return to_date(utl_http.request('http://ias4/asterix1_impl_cronet/server_time'), 'dd.mm.yyyy hh24:mi:ss');
  6  exception
  7    when utl_http.REQUEST_FAILED then
  8      return sysdate;
  9  end;
 10
 11  /

Function created.
```
Now get_server_time will give me the time of my first database server (unless the requested HTTP fails for any reason, then it'll be sysdate)
```
$[CHE_TEST@asterix2_al32utf8] select get_server_time from dual;

GET_SERVER_TIME
-------------------
24.07.2012 13:35:00
```
Again, if you go in this way use the feature carefully and not at each end of your application as it will give you performance problems .

see you soon

Redirect to another page with parameter passing using the POST method
Hello

I need to redirect to another page and pass parameters to it with the POST (not GET) method. How can I do?

So far, I tried the 2 options and none of them works very well:
1. I wrote a pl/sql procedure, but if I run it, then the page runs on my server application instead of actually going to another page in another server (I see the neame of the procedure in the web browser's address bar). Is there a way to work around a bit so that really, it goes to another page and pass the variables?

procedure do_post)
p_api_url in varchar2)
is
l_http_req utl_http.req;
l_http_resp utl_http.resp;
l_response varchar2 (4000);
l_post varchar2 (4000);
v_line varchar2 (4000);
v_wallet varchar2 (100): = "file:/etc/ORACLE/WALLETS/oracle5";
v_wallet_pwd varchar2 (100): = "test1234".
Start
l_post: = ' VK_SERVICE = 1001 & VK_VERSION = 008 & VK_SND_ID = testvpos & VK_STAMP = 88';

Utl_http.set_Proxy (apex_application.g_proxy_server, NULL);
Utl_http.set_persistent_conn_support (true);
Utl_http.set_transfer_timeout (300);
Utl_http.set_wallet (v_wallet, v_wallet_pwd);
l_http_req: = utl_http.begin_request (p_api_url, 'POST');
Utl_http.set_header (l_http_req, "Proxy-Connection ',' Keep-Alive'");
Utl_http.set_header ("l_http_req, 'Content-Type', ' application/x-www-formulaires-urlencoded; charset = utf-8 ');
Utl_http.set_header (l_http_req, "Content-Length", length (l_post) ");
Utl_http.write_text (l_http_req, l_post);
l_http_resp: = utl_http.get_response (l_http_req);

LOOP
Utl_http.read_line (l_http_resp, v_line, TRUE);
HTP.p (v_line);
END LOOP;
Utl_http.end_response (l_http_resp);

EXCEPTION
WHEN utl_http.end_of_body THEN
Utl_http.end_response (l_http_resp);
end do_post;

2. the second option, I tried is to put this script to my page of request code:

< name of the form = 'mounted' action = 'https://www.somekindofurl.com/cgi-bin/dv.sh/un3min.r. '
method = "POST" target = "_top" >
< input type = "hidden" name = "VK_SERVICE" value = "1001" >
< input type = "hidden" name = "VK_VERSION" value = "008" >
< input type = "hidden" name = "VK_SND_ID" value = "testvpos" >
< input type = "hidden" name = "VK_STAMP" value = "88" >
< input type = "submit" value = "Let's's Pay" >
< / make >

< / make >

But it does not work as APEX has its own system of Forms control. Is it possible to play? I tried to delete #FORM # of page templates and it works fine then. The problem is that I have other forms on the page as well (login form + search form) so I can't remove this manipulation of shape native APEX. Is it possible to play with it?

Thank you much in advance.
Hi Ibenarobeno,

Your form can live at the end of the page with all the hidden items.

You can then control with buttons and fields within the form of the Apex.
through a bit of javascript.

How to catch the error in time-out in BEPL

Hi, I am building some SOA BPEL to call another SOAP service that may treat the time quite a long time. In this case, SOA BPEL fails with ErrorCode ORAMED-03303. In order to ensure the completion of the entire BPEL process, I tried to add a CatchAll to intercept this error. But FAILED. The BEPL still does not with ORAMED-03303. Can someone help me on this? Thank you.

Hi Lisoft,

You might see these errors because of the long running process. There are several places where you have to fine-tune the settings of time-out.

The first thing you should look into is the MBean timeout "SyncMaxWaitTime" which is set by default at 45 seconds. (Connect on SOA EM > SOA > click right on soa-infra > Administration SOA > BPEL properties > more BPEL properties > SyncMaxWaitTime). You then have to check what the JTA transaction time-out set for the instance of weblogic (connect on the SOA console-> click-> JTA field).

You can control the time-out settings max on a composite level using "oracle.webservices.httpReadTimeout" and "oracle.webservices.httpConnTimeout" binding properties. These values configured in the composite must be less than the value of the "SyncMaxWaitTime" for synchronous processes.

If you use the properties mentioned above for your Web service reference, then you could catch the fault of "timeout" in your composite. The binding reference might look like below in the file composite.xml.

UI:wsdlLocation = "TestService.wsdl" > "

http://xmlns.Oracle.com/SOATestWSService/TestWSService/bpelTestWSService#WSDL.interface (bpelTestWSService)"/ >

http://xmlns.Oracle.com/SOATestWSService/TestWSService/bpelTestWSService#WSDL.EndPoint(TestWSService_ep/bpelTestWSService_pt)"

location =""

soapVersion = "1.1" >

much = 'false' override = "may" > 10000

much = 'false' override = "may" > 10000

much = 'false' override = "may" > false

Hope the link below could be very useful for you.

Hi all

Problem solved now I am able to run and error disappeared with changes below.

Go to JDeveloper-> Navigator-> ViewControler project properties > JAVA EE Application > integrated command-line WLS.

Precedent has been

${java} ${} jvm - classpath ${oc4j.jar} {java.options}

${oc4j.environ.type} ${memory.archive.flag} {keep.alive.timeout.flag}

${oracle.jms.lock.flag}

${oc4j.main.class} - config ${server.xml}

Replace it with

${jvm} ${java.options}

Reason: Instance OC4J from 10g Application after migration is still there, but in 11g application using weblogic instead of oc4j.

Thanks and greetings

Scheduled task
Hello

We have a scheduled task that runs every 30 minutes, the work envokes a web service that sends data to another agency. The problem is the following:
When the job is run every 30 minutes, we get the following error message:
91 - logging of errors on WS--29273: ORA-29273: failure of the request HTTP ORA-06512: at "SYS." UTL_HTTP,"lin
Code to submit work:
DECLARE
jobno NUMBER;
BEGIN
Dbms_job. Submit
+ (work = > jobno +)
+ This = > ' start SEND_DATA. SEND_LOG_TO; end; » +
+, next_date = > SYSDATE +.
+ interval = > 'SYSDATE + 1/48'); +
COMMIT;
END;

BUT when the WS is called with the following code:
Start SEND_DATA. SEND_LOG_TO_NRF; end
It does not error.

You can change the package WS because it provided by the organization from the outside.

Does anyone have advice - is it permissions on the firewall or something that is not configured correctly?

Thank you
Roald
Yes, maybe...

To the inside of the package where the url is called... you can increase the time-out url to something like 5 min...
```
utl_http.set_transfer_timeout(300);
