Apex_collection.update_member - call to results in DEADLOCK

We have a wrapper procedure that calls 'apex_collection.update_member'.
This wrapper procedure is an AUTONOMOUS TRANSACTION (to preserve any collection updates if an error/rollback occurs).
We now have the situation where the call to the wrapper procedure is generating a DEADLOCK on 'UPDATE WWV_FLOW_COLLECTION_MEMBERS$'.
I suppose the advice will be to not have the wrapper as an AUTONOMOUS TRANSACTION. Fair enough, but I would like to know why this is occurring ?
Any advice appreciated.
Cheers
Nigel

Nigel:
The Deadlock graph shows that the waiter and the blocker to be the same session with each wanting an exclusive lock (X) on the same record. In your case the first transaction was what APEX initiated and the second one is caused by the call to the 'auto trans' procedure and these transactions presumably want to act on the same collection member. Hence, removing the 'auto trans' from the procedure is the way to avoid this issue.

APEX_COLLECTION.UPDATE_MEMBER not Working

Hi.
I hope someone can help on this matter.
I have been working with Apex for some time on and off and I and have accomplished more complicated stuff then this.
Bit this has stopped me in my tracks for 2 days now.
To the point.
Onload I create a collection from where I populate a small classical report with a edit link redirecting to a URL(little javascript).
All this does is show a hidden html region with a few text fields and populates it with the values from the selected row from the report.
This is then edited and saved, but NOT submitted.
The save button once again, redirects to a URL(Another small javascript) that passes the values to an On Demand Application process.
Up to this point everything works fine.
The process is executed and by different tests I know the values are being received.
What is suppose to happen is the HTML region gets hidden again and the report refreshed from the collection again.
That work perfectly BUT.
For some reason, the APEX_COLLECTION.UPDATE_MEMBER just won't work and I have used this many times before.
It also DOES NOT PRODUCE ANY ERROR.
I subsequently broke the application in to a small test but it still won't work.
The code follows.

I know there will be questions as to why I am doing it this way without submitting the page, so all I will say is that this is just part of a much bigger page with a lot more values to be set before submitting, validation, and processing.
I really hope someone can help
JJ

Hi Peter.
Firstly, thank you for your response.
I have used APEX_DEBUG, with no results.
To check if my values, I have changed the on demand process to actually update the table and not the UPDATE_MEMBER part,
DECLARE
   l_collection_name APEX_COLLECTIONS.COLLECTION_NAME%TYPE;
BEGIN
/* l_collection_name := 'TEST1'
    APEX_COLLECTION.UPDATE_MEMBER (
        p_collection_name => l_collection_name,
        p_seq => apex_application.g_x01,
        p_c001 => apex_application.g_x02,
        p_c002 => apex_application.g_x03,
        p_c003 => apex_application.g_x04);*/
update t_test set t_name2 = apex_application.g_x01 || ' - ' || apex_application.g_x02 || ' - ' || apex_application.g_x03 || ' - ' || apex_application.g_x04;
commit;
END;
It updates the table fine and I get my concatenated string in my second string column when checking the database.
I went through it again and again.
The APEX_COLLECTION.UPDATE_MEMBER call looks ok to me.
Maybe I have been staring at it to long, but unless I am missing something, I really don't see anything wrong.
Any ideas?

Application code should not call ensureCache as this may result in deadlock

I'm seeing this on the coherence console. I don't think I'm calling ensureCache anywhere in my code.
Oracle Coherence GE 3.4.2/411 <Warning> (thread=DistributedCache, member=4): Application code running on "DistributedCache" service thread(s) should not call ensureCache as this may result in deadlock. The most common case is a CacheFactory call from a custom CacheStore implementation.
-Andrew

Take a look at any CacheStore or EntryProcessor implementations you have. In general, it is a bad idea to try to operate on the same cache service while running on that service (e.g. from an EP).

Apex_collection.update_member results in no data found found

I'm trying to build a simple scheduling grid using a collection to show who is available on what day of the week. This is the table:
CREATE TABLE WORK (
USER_ID NUMBER(9) NOT NULL,
MON VARCHAR2(1),
TUE VARCHAR2(1),
WED VARCHAR2(1),
THU VARCHAR2(1),
FRI VARCHAR2(1),
CONSTRAINT WORK_FROM_HOME_PK PRIMARY KEY (USER_ID));
My create collection script is:
if apex_collection.collection_exists(p_collection_name=>'WFH') = TRUE then
apex_collection.delete_collection(p_collection_name=>'WFH');
end if;
apex_collection.create_collection_from_query(
p_collection_name=>'WFH',
p_query=>'SELECT user_id,
mon,
tue,
wed,
thu,
fri
FROM work');
As I try to sort this out, I have two reports on the page. One is for the schedule/collection processing, & the other simply shows the collection so I can verify changes:
SELECT seq_id, c001 emp_id, c002 mon, c003 tue, c004 wed, c005 thu, c006 fri -- my working query
FROM apex_collections
WHERE collection_name = 'WFH'
select * from apex_collections -- this shows the entire collection
where collection_name = 'WFH'
I have 2 buttons & processes to add new rows & undo changes, & a button for updates. (I'm not trying to update the underlying table yet, just update the collection.) The add & undo seem to work fine. When I try to update the collection, I get a "no data found" error. The update collection process is:
BEGIN
FOR i IN 1..apex_application.g_f01.count LOOP
apex_collection.update_member(
p_collection_name => 'WFH',
p_seq => apex_application.g_f01(i),
p_c001 => apex_application.g_f02(i),
p_c002 => apex_application.g_f03(i),
p_c003 => apex_application.g_f04(i),
p_c004 => apex_application.g_f05(i),
p_c005 => apex_application.g_f06(i),
p_c006 => apex_application.g_f07(i));
END LOOP;
END;
I suspect there is a problem with the way I'm trying to reference the sequence, but have yet to figure it out.
Suggestions?

As you can see below, the sequence & emp_id are not getting assigned the f01 or f02. That starts with the updatabl fileds on the report.

Java- Stored Procedure with Call by Result

Hi Oracle-Community,
I am looking for some example Code how to use a Java-Stored Procedure with Out-Parameters. Don't get me wrong. I dont want to call a Procedure with Out Parameters from Java (there are a lot of examples for this out there) . I just want to implement the Call by Result concept in a Java-Stored Procedure. A Client will call this Procedure with some parameters and the Java Procedure will fill them. So my first question: is this possible? And my second Question: How to implement it?
Greetings.

I found out a solution. It is very simple.
Just defining the parameters as java array (e.g. String[] P1). The first value (P1[0]) is the returned value.
At last just set in JDeveloper in the "Edit Method Signature" Dialog the parametermode to OUT.
The dialog can be found by rightclicking on the stored procedure in the dbexport file. You can read this
in Section 6 Publishing Java Classes With Call Specifications -> Setting Parameter Modes in
Oracle Database Java Developer's Guide.

Apex_collection.update_member. What am I doing wrong.

I am able to create my collection, then select from it. Unfortunately, I am not able to get it to update. I have been able to do this for other collections, so I am stumped...and believe it is something simple I am doing wrong....any thoughts? thank you.

Result handler of a remote call not executed till the other remote calls get result

I have 3 remote calls in sequence.
Say RemoteCall1, RemoteCall2 and RemoteCall3. RemoteCall1 takes the least time say 5 seconds to get results. RemoteCall2 also 5 seconds and RemoteCall3 takes 30 seconds. But the resulthandler for RemoteCall1 does not execute till the RemoteCall3 gets results from server. Any fixes to call resulthander for RemoteCall1 as soon as it gets result without waiting for RemoteCall3 results.
by the way I am usindg Robotlegs framework and AsyncToken.

Don’t make remoteCall3 until you get the results from remoteCall2, etc. That’s the only way I know to guarantee order.
Fllash queues up all remote calls until the end of the frame and sends them all at once, although a network monitor should show that the go out in the order you made the calls.
Similarly, Flash processes all available results at the end of a frame. Results are asynchronous, but if all three results arrive in the same frame, they will all get deserialized. And, the server may not be guaranteed to return results in the order requested, especially if different servers are handling the individual calls.
I’m not sure if your time to get results is gated by server response or Flash processing the results. I suspect it is the latter. You also have the option of changing the resultFormat to get something that doesn’t need processing like XML and process it later.

HTTP Rest api call maximum results

Hi all,
I´m trying to get data from the portal using the follwoing rest api call:
http://<ServerURL>/RequestCenter/nsapi/serviceitems/serviceitemsubscription
but it only gives me 20 results, which I believe it is the default, is there any way to get all the elements or a way to page all the results?
Thanks
Alex.

Hi all,
found some info on the Integration guide (Cisco Prime Service Catalog 10.0 Integration Guide) page 222, there is a section regarding Paging, but the max results are 50.
I was looking a simple way to export / import info from the portal, but it seems Java is going to be neded instead http nsapi.
Regards,
Alex.

I notice I have an add on called search results optimizator 8.17, I do not remember deliberately installing this add on and I cannot uninstall it, I have disabled it as it redirected me to a search site when I logged on to Photobucket, I would like to kno

I have enabled the add on again to find the web page it directs me to...
http://www.landing.savetubevideo.com/
This is the page it takes me to when I try to log into Photobucket.
I did install a Youtube downloader from SaveTubeVideo but un-installed it. The Search Results Optimizator must have been installed at the same time. But it does not give you an option to remove it, only to disable it.

Hi TwoSheds,
System-installed extensions can't be uninstalled from Firefox. Instead you can find and remove this application from Start -> Control Panel -> Add/Remove Programs.
However, disabling an add-on renders it fully inert; it isn't loaded at all and can't do anything.

Calling SP results in ORA-00911: invalid character

I am testing a supposedly very simple stored procedure in XE. It compiles with no errors but when I enter the following command in the SQL Command window I get an ORA-00911: invalid character.

create or replace procedure get_all_customer_orgs (p_recordset out sys_refcursor)

I don't understand what the invalid character could be. Guidance? Thanks.

I don't have XE handy, but your procedure works from SQL Plus (changing the table to emp).

Portal Eventing calls BAPI - result FAILURE!

Hi All,
I have an interesting delima.
BAPI_SALESORDER_GETSTATUS - using portal eventing to set "Salesdocument" model/mapped context value. When executing Bapi, no results display in my table (mapped to the output values).
In further testing, I added an InputField that was mapped to "Salesdocument" to see that it was being set properly before the Bapi execution. That worked so I could see that portal eventing was working correctly. Still no results though.
When I changed the "onEnter" event of the InputField to use my method that executes the Bapi, then the results showed up just fine. It appears that somehow the results only display if a InputField submits the value it is looking for.
Any ideas on how to get the results to display? I thought maybe it had to do with the data type, but the context only asks for a string value.
Max reward points for the person(s) who help me the most.
Much Thanks,
Cameron

Hi Cameron,
If I understand you correctly, the parameter <i>dataObject</i> in the action handler <b>onActionGetSalesDocument</b>
refers the value the you want to pass to the Import parameter <i>SALESDOCUMENT</i>.
If yes, then try doing the following two modifications.
Define a new parameter <i>dataObject</i> of type <i>String</i> for the method <i>execute_Bapi_Status_Details_GetList</i>
Change the action handler onActionGetSalesDocument as follows.
public void onActionGetSalesDocument(IWDCustomEvent wdEvent, String dataObject)
wdContext.currentContextElement().setSalesDoc(dataObject);
wdThis.wdGetStatusDetailComponentController()
.execute_Bapi_Status_Details_GetList(dataObject);
wdThis.wdFirePlugToDetailView();
Add a line of code to the execute_Bapi_Details_Getlist as follows:
public void execute_Bapi_Status_Details_GetList(String dataObject){
try{
      <b>wdContext.currentStatusDetailsModelElement()
.setSalesDocument(dataObject);</b>
    wdContext.currentStatusDetailsModelElement()
.modelObject().execute();
      <b>wdContext.nodeOutput().invalidate();</b>
}catch(Exception e){
      <b>wdComponentAPI.getMessageManager.raiseException(e.getMessage(), true);</b>

After iOS 7 update, trying to call just results in echo feedback loop.

It's happening to both my wife and I. She has a 4S, I have a 5.

I have the same issue. Phone echo's like a toy mic after call ends. I am on the iPhone 5 with version 7.0.4. I even swapped for a new handset and it did not fix the issue. This never happened iOS 6.
Can someone please help as it is very annoying and deters you from making the next immediate call.

Calling results of a method from another class

Very very new to Java, so apologies for the lack of basic knowledge. I am making a programme with 3 classes. One class gathers details about a module. Another about the results of this module (which requires some of the information inputted for the first class). For some reason I cannot find how to use results created in the first class in this second class. How do you call the results of a method from one class in another class?
Thanks.

Thank you.
I am given the following information:
'_ModuleRecord_
This class is used to record information about a module taken by a single student. It has a constructor that takes three parameters:
a Module,
an int representing the examination mark achieved by a student, and
an int representing the coursework mark achieved by a student.
The class has another constructor that takes a single Module parameter.'
and the code looks like this:
public class ModuleRecord
public ModuleRecord(Module m, int eMark, int cMark)
public ModuleRecord(Module m)
} I am a bit confused by the whole thing to be honest. I assume that the Module is referring to the other class, but how do I forge the link between them here?

Howto get result of the calling-step in SequenceFilePostStepFailure

Hello,
i have a sequence with a SequenceFileCallback "SequenceFilePostStepFailure".
How can i create a popup that displays the following values:
- Name of calling-step
- sequence-name of calling step
- result of calling step
- limit (low, high, string) of calling step
I found:
RunState.Caller.Step.Name,
RunState.Caller.Sequence.Name
but nothing for result and limits.
Thanks for any help

This should handle what you're looking for and then some. I use this with the retry expression that allows for the whole sequence to be repeated. Probably shouldn't allow for the "Force Pass". I think it origianally came from TestStand examples and I modified it, but I couldn't tell you which example.

APEX_COLLECTION - how to update MD5_ORIGINAL

Hello everybody,
is there a possibility to recount MD5 hash of APEX_COLLECTION member and store it back to MD5_ORIGINAL?
My situation is as follows:
When users is going to edit the table, he sets some filter (lets say year). All data concerning that year are then copied into collection (actually, collection is created from query, p_generate_md5=>YES). Then user performs some changes and submits.
My underlying code is like this:
1. for all data in user form call apex_collection.update_member
2. perform some checks on data (not important here)
3. for each collection member where (md5_original != get_member_md5) update corresponding row in table and this is what I need: save the result of get_member_md5 into md5 original, so that next time user submits I won't update same rows again.
There seems not to be any function with that functionality in APEX_COLLECTION API. Any ideas?
Thanks!

Hi,
Sorry - you are right, I've checked the available methods for the apex_collection package and there is no method call that allows the update for this value. And we do not have the right access rights to update this value directly on the table itself.
The only thing I can think of is to delete the original record and add it back in with the new values. Because you have set the p_generate_md5 parameter to YES, this will generate the new checksum. Of course, that would leave a gap in the collection (deleted members are not removed) and the new record would be at the end but you can re-order them if required.
If, however, you are using pl/sql to control the update of records, you could use the APEX_ITEM.MD5_CHECKSUM() function to get the MD5 value and store it on, say, c050?
