  Hi all
  
  APEX Version: 4.0.2.00.07

  Portfolio info has been set up at the level of the APEX body, so APEX can access active SSL sites.
  
  When I run the code in the following process page, to make the SOAP request to our intranet JIRA instance, works just fine.

  END;

  However if I call a webserivce RESTful API using "apex_web_service" then I've always done with following error message.
  

  The webservice was unreachable because either the URL you supplied was invalid, your environment requires a valid proxy server address for HTTP requests, or a wallet needs to be configured for HTTPS requests.

  Code (call RESTful)

  DECLARE
       lc_response CLOB;
  BEGIN     
       apex_web_service.g_request_headers(1).name := 'Authorization';
       apex_web_service.g_request_headers(1).value := 'Basic '||:F_JIRA_TOKEN_REST;
                                                                   
       lc_response:= APEX_WEB_SERVICE.MAKE_REST_REQUEST(

                                                                   );
  END;

  As you can see, the two requests are made to the same server. However during the SOAP request I get no errors, but in a restful query I get the error message. Can someone tell me what could be the problem?
  
  Best regards

  Hi Hari,

  It's bug 16212066 - apex_web_service make_rest_request uses a wallet of the instance if it is not specified
  which will be corrected in the APEX 4.2.2.

  To work around the problem, you can specify the parameter p_wallet_path and p_wallet_pwd when you call apex_web_service.make_rest_request.

  Chambers,

  You can use wwv_flow_utilities.array_element to avoid any no_data_found. The function does not raise any errors. For example, for the line which only have a value of table when you wait 2, it can be useful.

  EXECUTE IMMEDIATE 'insert into table_name@Schema1 (col1,col2)
      values (:1,:2)'
      USING
        wwv_flow_utilities.array_element(v_data_array,1),
        wwv_flow_utilities.array_element(v_data_array,2);

• When Firefox restarts the pages that they do not charge just display story, I then have to refresh to get new data as Explorer always charging and Firefox used to

  This should be an easy solution, because all the other browsers and Firefox used to do this. Firefox is restarted the pages do not charge they just historical display. I have to hit the button reload current page to get new data. This has been driving me crazy for a few weeks.

  People like you that encryption data with bitlocker do it because they want their data accessible only by those who have the certificate. The sad news for you is that you have made a good choice with BitLocker: unless you have the certificate, your data remains inaccessible. There is no backdoor.

  Thank you

  Vijaya

  You can get the data center in which the virtual machine resides by the following search:

  VM Moref-> Parent (vmFolder)

  Moref folder VM-> Parent (data center)

  Parent of the virtual computer object will always be the vmFolder and the vmFolder object will always be a data center.

  PT

  When you're in approvals, there is no form of process data. Process form data would come only when approvals are completed. If you want to read data from the child form of the DataSet (i.e. the form object as in OIM9.x) you can use the RequestService on the id of the request and read the data. Or another approach would be to the child the dataset data value in the payload of the request and read the XML payload in the composite.
  Let me know if you need more information about the second approach. As for the first approach, search through the forums here and you should find my previous posting on how to reach child dataset values using the ask service API.

• apex_web_service.make_rest_request: passing parameters and the type of content

  Don't know if I'm missing something, but should this API show the content type (application/x-www-url-formencoded) when there are values for the p_parm_name and p_parm_value parameters.
  
  The example in the docs is a Yahoo API. I'm not sure that an individual (see: http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_web_service.htm#BABEDJHJ), and I think that it requires an appid (yahoo account), so I went with the example here:
  
  http://developer.Yahoo.com/YQL/guide/YQL-code-examples.html#yql_php
  
  If I run the following from a file html on my desktop, it works:
  

  <form method="POST" action="http://query.yahooapis.com/v1/public/yql">
  
  <input type="hidden" name="q" value="select * from upcoming.events where location='San Francisco' and search_text='dance'"></input>
  <input type="hidden" name="format" value="json"></input>
  <input type="submit"></input>
  
  </form>

  In other words, it returns a JSON result.
  
  The raw data of HTTP are as follows:
  

  POST http://query.yahooapis.com/v1/public/yql HTTP/1.1

  Host: query.yahooapis.com
  Connection: keep-alive
  Content-Length: 110
  Cache-Control: max - age = 0
  Origin: null
  User-Agent: Mozilla/5.0 (X 11; Linux x86_64) AppleWebKit/536.11 (KHTML, like Gecko) Ubuntu/12.04 Chromium/20.0.1132.47 Chrome/20.0.1132.47 Safari/536.11
  Content-Type: application/x-www-formulaires-urlencoded
  Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
  Accept-Encoding: gzip, deflate, sdch
  Accept-Language: en-, FR; q = 0.8, fr; q = 0.6
  Accept-Charset: ISO-8859-1, utf-8; q = 0.7, *; q = 0.3
  
  q = select +upcoming.events+where+location%3D%27San+Francisco%27+and+search_text%3D%27dance%27 & format = json >
  
  However, running the following returns nothing: (nothing, nothing of which depends on the parameters passed in)
  

  set serveroutput on
  
  declare
  
  l_c CLOB;
  
  begin
  
  
    l_c := apex_web_service.make_rest_request(
      p_url => 'http://query.yahooapis.com/v1/public/yql',
      p_http_method => 'POST',
      p_parm_name => apex_util.string_to_table('q:format'),
      p_parm_value => apex_util.string_to_table('select * from upcoming.events where location=''San Francisco'' and search_text=''dance'':json'),
      p_proxy_override => 'http://192.168.1.3:8888');
  
    dbms_output.put_line(substr(l_c, 1, 4000));
  
  end;

  Raw data from HTTP:
  

  POST http://query.yahooapis.com/v1/public/yql HTTP/1.1

  Host: query.yahooapis.com
  Connection: Keep-Alive
  Content-Length: 106
  Connection: close
  
  q = 2 Select + % + of + coming % 2Eevents + where + % 3D 'San + Francisco' + and + % 3D search_text 'dance' & format = json >
  
  I note that one key difference is that content type is not defined in the web service API.
  
  It was just to test a public service. I note that the foregoing has slighty different encoding request (percentage of tanks). However, I experienced the same behavior on a procedure that I wrote (I can also give this example of test cases if you wish), which is where I first noticed the issue.
  
  Using utl_http and affecting the type of application/x-www-url-formencoded content, does not solve the problem. However, just thought I'd see the possibility of using the service API Web that is made available.
  
  The example is in the valid docs, or am I missing something obvious?
  
  It's Dev days on ApEx 4.1 on the virtual machine in the RTO.
  
  Thoughts?

  I had a similar problem:
  apex_web_service.make_rest_request packaging missing header parms

  I endedup an SR for Oracle to open. I discovered that the headers (content-type) are defined in global variables before calling apex_web_service.make_rest_request.

  See http://docs.oracle.com/cd/E17556_01/doc/apirefs.40/e15519/apex_web_service.htm#autoId4 for a description of headers and cookies.

  I endedup have to add the following to my code before apex_web_service.make_rest_request:

  apex_web_service.g_request_headers (1) .name: = "Content-Type";
  apex_web_service.g_request_headers (1) .value: = ' application/xml ';

  Once I did, my service works. Odd. Not sure why they did it this way because their internal packages use parameters of the header, but the wrappers do this way, I guess.

  I hope this works for you!

• EntryProcessor get outdated data

  Hi all
  
  We have an EP quite complex where we have many requests for appeals against the same entry. This is normal and consistency would lock each entry of confidence we didn't assume any problems in this area.
  
  However, under a heavy load (with several requests in queue), we see the EP get out of date data, i.e. it is the entry because it was at a previous time, but not as his last stored on the previous EP run on this entry. Basically, we can always to each test see the following events:
  
  1 deserialize the entrance, the sequence number = 1
  2. given EP entry with sequence number = 1
  3. serialize the entry, the sequence number = 2 (of the EP to the point 2)
  4 deserialize the entrance, the sequence number = 2
  5 deserialize the entrance, the sequence number = 2
  6 EP given entry with sequence number = 2 (So far, so good)
  7 serialize the entry, the sequence number = 3 (of the EP to the point 6)
  8 EP given entry with sequence number 2 = (* this is false and just point 5! *)
  9 serialize the entry, the sequence number = 3 (from EP to point 8, which took place on stale data)
  
  And so on... So it's all on one key, but the reading and writing to/from binary entry happens out of order, which makes the EP get outdated data.
  
  I work on a simple test case that I would be able to share and allow us to eliminate all surrounding logic. But I would just ask if someone has seen something similar? We manage this on 3.7.1.4, and testing is all in Java on a single node.
  
  EDIT: Guess it's worth adding that it is with 10 threads to service. If we run with just the wire of single service, the service seems to crash a lot, but I'll need to come back with more details on this...
  
  Edit2: The exceptions we have obtained with only one thread was basically just the guardian being too strict and we have been able to pass the test with a single thread. Therefore, it seems that this question is there when we have multiple threads available service.

  Hello

  I took a deeper look at your test case - thank you for the effort in the creation. It seems that you use a HashMap to your key with the value of the card being an OtherHolder which itself has a HashMap with 1000 points. When determining the partition entry belongs to use us the hash of the binary key and the serialization of a HashMap browse us every input serialization key / value. Iteration order is not guaranteed with a HashMap deserialize it serialize-> serialize can result in two different binary producing different hash codes so different entries in the cache.

  Applied to your test case I noticed that you have to 'revive' within your DataHolderEP logic that calls cache.invoke using the deserialized from the input that you do not currently have (discount to a separate thread). This deserialize and serialize an invoke on a new key that triggers your CacheLoader calling and causes a new DataHolder of object returned. You have now two DataHolder objects, so your incremental version check fails. You could modify your implementation of the map to a LinkedHashMap at two construction in OtherHolder #readExternal or do not use a key card. You can run into problems when using large keys with features like caches close.

  In addition, you can consider changing your test so that it works against the remote processes such as logic such as serialization and deserialization of the EntryProcessor is never called.

  Thank you

• Arbitrary large amounts of binary data in a clip of loading

  It is easy to download external data in XML format to a clip. However, what I need must load really large volumes of data binary readonly. In my case, the text representation is not an option. Is it possible to download an arbitrary array of bytes in memory, then get this table to read the individual bytes?
  
  I don't think that the forth tables like this
  var data: Array = [1,2,3,...];
  could be solution for my problem either. The reason is that the VM so much additional information associated with each Member of the group.
  
  The only solution that I came here is to pack binary data as strings,
  var data: String = "\u0000\u1234\uabcd";
  two bytes per character. Avoid any overhead storage, and searching for a member of individual data is trivial.
  
  But I doubt there is a better solution?
  

  I don't think that there is another option other than to load it into a string and then encoded the decode internally to as2. So if you have \u0000 as in the example above, you will find that it does not work.
  var data: String = "\u0000\u1234\uabcd";
  (Data.Length) evidence //traces 0 (zero) as the first character is a string terminator

  I think you need a method of encoding as base64 in the source string and an equivalent class of decoder to decode to binary flash inside. I'm no expert on this stuff... others may learn more, or it could be a starting point for your search.

  In the past, I used the classes meychi.com for this sort of thing. Could not see them online now... but there is something else here that may be useful:

  With as3 - if I understand correctly - it is not a problem because you can load binary data.

• binary data from GPS VI-example RF recording / reading with NI USRP

  Hello

  In the demo video (http://www.ni.com/white-paper/13881/en) a ublox was used to record the GPS signal while driving. How is it possible to record with you - Center in a binary data format which is usable within LabView for the reading of the GPS signal? Ublox uses the *.ubx data format, is there a converter?

  Hello YYYs,

  The file was generated not by uBlox but by recording and playback VI.  An active GPS antenna, fueled by some amplifiers and mini-circuits was related to the USRP and the program created LabVIEW file (USRP being used as a receiver)

  Later the USRP is reading the file (generation) and the Ublox GPS receiver is to be fooled into thinking that its location is currently somewhere else.

• How can I get the data view to display the same amount of time I save?

  I use the Sound and Vibration Measurement Suite.  In the data view, I display a graph of time, the power spectrum, the Color Map and the waterfall.  I am also showing strength in numbers group for several bands and doing cutting-edge research.  I record 100 ms of the transient wave.  In the data view, why the temporal plots show several seconds of data?  What determines how much time will appear in the data view?  More important, the power spectrum reflects the power for the entire of several seconds of data displayed?  Same question for power in the values of band and cutting-edge research.  I want to just this data displayed for 100 ms of the wave that I record.  So, how can I get the data displayed (waveforms) and power numbers come only 100 ms of the recorded wave?

  Hi TimRsandiego,

  SignalExpress is programmed to display graphs with default scales based on the type of action, it's reading. These scales and settings can be changed by right-clicking on the graph, and then select Properties.

  If you are interested to learn more about how to use SignalExpress, I would recommend checking out some demonstrations/tutorials on NI.com. You can find some of these demos at the following location:
