Cube lock when multi-request insert at same time

Hi, experts,
I don't requite understand cube lock mechanism in BW.
right now I found if I load two data source A request into one cube when data souce B request is running, the cube is lock which cause both two job is go to dead waiting.
but I heard BW can allow two request loading to CUBE at same time, right? and cube only will be locked when it roll up data to aggregate.
anybody can make me more clear conception. thanks a lot

Hi,
See the locking logic:
http://help.sap.com/saphelp_sem40bw/helpdata/en/bb/bdd69f856a67418962d74bfd7bd8af/frameset.htm
Probably, reconstructing of indexes or updating statistics locks the cube.
Also here:
http://help.sap.com/saphelp_sem40bw/helpdata/en/91/270f38b165400fe10000009b38f8cf/frameset.htm
they said that "During parallel loading of requests in an InfoCube, these automatic processes can lock each other out".
Best regards,
Eugene

Does af:commandButton submit multiple requests at the same time?

Hi experts,
I have a question about af:commandButton behavior.
I have two commandButtons in a page. They are button1 and button2.
Button1 takes a few seconds to complete its request process.
So when I click button1, I can click button2 although button1 request is still being processed.
I checked how ADF faces handled this situation with servlet filter.
And I saw that button2 request was always submitted after button1 request was completed.
Due to this behavior, I would assume that commandButton is designed not to submit multiple requests at the same time and guarantees click order.
However I couldn't found any documents specifying this feature of commandButton.
If anyone knows it, could you share?
I know ADF Faces has busyStateListener to prevent user inputs during request round trip.
But I'd like to make it sure that I don't need to use busyStateListener if I just want to keep processing order.
Regards,
Atsushi

Hi,
Does anyone know the document specifying the behavior of af:commandButton in case I click two buttons in a page almost simultaneously?
Any help will be much appreciated.
Thanks in advance,

User Defined Table locked when multi users try to save data?

Hi All,
I am having a problem with User Define Table (UDT). I am just checking if somebody having the same problem as mine (any patch level).
I've developed an add-on to save additional data to some UDTs upon saving a Production Order. I added my code in FormDataEvent (After Action = True and ActionSuccess = True).
Here are my sequences to save the data:
1. Start Transaction
2. Remove Existing Data from 3 UDTs linked to the production order number.
3. Save to table 1, using UserTable object
4. Call function A to save to table2 , using UserTable object
5. Call function B to save to table 3, using UserTable object
6. Commit Transaction.
Note: I have a try catch and rollback the transaction if any exception thrown by .NET and SAP. Below are parts of my coding to handle exception from SAP
                If oUserTable.Add() <> 0 Then
                    oCompany.GetLastError(ErrCode, ErrMsg)
                    Throw New ApplicationException(ErrCode & "-" & ErrMsg)
                End If
in the try catch block, i add the following code
            If oCompany.InTransaction Then
                oCompany.EndTransaction(SAPbobsCOM.BoWfTransOpt.wf_RollBack)
                SBO_Application.MessageBox("[SaveRoute]:" & ex.Message)
                Return False
            End If
Now, the issue is in some occasions, when multi users try to save the Production Order, the data get deleted from the UDTs, but some of the data did not get saved yet it did not throw an exception. From our observation, it only happens when multi users are trying to save to the same table.
Does anybody having the same or similar issue? Really appreciate if you can share on this.
Many Thanks,
Harianto Ng

I Believe you should look carefully where in your code writting, you should start transaction and be sure of using end.transaction commit if the insert sends a succesfull message, and rollback it for negative message.
I used to start transacción right before .add method
Wha DBMS are u using?
Hope it helps.

How to avoid deadlock when multithreading updates one table same time?

Multithreading calls the stored procedure at the same time to update data in one table. For a instance,
Table1
Col1 Col2 Col3
C1 1 1
C1 2 2
C1 3 3
C2 1 1
Table2
Col1 Col2 Col3
C1 1 10
C1 2 4
C1 3 3
C2 1 1
There are several steps I want:
1. Get the data in Table1 where Col1 = C1 in a cursor which has Col1 column and Col2 column.
2. Cycle them one by one, and get the Col3 data from Table2 where Col1 = C1 and Table2.Col2 = Table1.Col2. (Due to deadlock is my concern, we use temp table, definityly it is not a good way. :( )
3. Update Table1 Set Col3 = Table2.Col3.
My new idea is when I get the collection from Table1 which Col1 = C1, I use this way below.
First I set transaction in below way.
SET TRANSACTION ISOLATION LEVEL READ COMMITTED;
Then
select * from Table1 where Col1 = C1 for update nowait;
In my opinion, if one thread lock the data for update, other thread won't select out that locked data. Does it work?
Thank you.
Best regards,
Andreas

Why is the data submitted as a collection in the first place?
A collection is great as a program data structure - dealing with program variables. It is a very poor choice to use it to deal with Oracle data in a CRUD fashion.
The purpose, ito dealing with Oracle data, of a PL/SQL collection is for one thing and one thing only - context switching.
To reduce the number of times you need to step out of PL/SQL and into the SQL engine in order to pass data from one to the other. A collection allows you a bigger buffer area and thus less context switches.
And that's it.
A client (Java, C#, etc) that submits data to Oracle to be CRUD via a collection is a design flaw. A collection resides in "expensive" dedicated, non-sharable and non-scalable server memory.
In order to CRUD a collection, you either need to write bare bones feature methods yourself, or cast that collection into a SQL structure and use more powerful and flexible and feature rich SQL against it.
Which then begs the question - why did the client not submit that data directly to the SQL engine, either into a permanent table or a temporary table?
Performance and scalability are issues that need to be addressed at core design level. It is not something that can be tacked on and "fixed" after the fact. So you need to make very sure that your reasons for not wanting to use a temp table (for example), are valid and sound technical reasons.

How to let user download multi files at the same time in WebDynpro ABAP?

hi all:
As you know, WeyDynpor has provided upload/download UI element, but it seems that it only support one file upload/downlaod at the same time.The following is the API method to download one file in Webdynpro:
    cl_wd_runtime_services=>attach_file_to_response(
     EXPORTING
       i_filename      = lv_filename
       i_content       = lv_content
       i_mime_type     = lv_mine_type
       i_in_new_window = abap_true
       i_inplace       = abap_false
*      EXCEPTIONS
*        others          = 1
but if when use click one button, we want to provide user a html file plus 2 icons files which are used as this html file's resource file, then how to let user download these 3 files together at the same time?
one simple way is calling the download api (cl_wd_runtime_services=>attach_file_to_response) 3 times,
but it is very ugly that three popup windows are shown to let user select every file's download path, which is unaccepted.
So anyone know more convienient way to handle it?
thanks.

Hi,
I suggest you to zip the files and attach it to the response. Do the add file part for each of your files
     "References
     DATA lr_zip TYPE REF TO cl_abap_zip.
     "Variables
     DATA lv_zip_xstring TYPE xstring.
     DATA lv_zip_name TYPE string.
     DATA lv_file_content TYPE xstring.
     DATA lv_file_name TYPE string.
     "Create instance
     CREATE OBJECT lr_zip.
     "Add file
     lr_zip_attachments->add(
       EXPORTING name = lv_file_name
              content = lv_file_content ).
     lr_zip_attachments->save( RECEIVING zip = lv_zip_xstring ).
     "Attach zip file to response
     cl_wd_runtime_services=>attach_file_to_response(
       EXPORTING i_filename      = lv_zip_name
                 i_mime_type     = 'ZIP/APPLICATION'
                 i_content       = lv_zip_xstring ).

IPad 2 stuck in portrait, mute switch locks orientation and mutes at the same time.

Ok, since I've had the iPad this problem has gone from bad to worse. Originally my iPad would get stuck in an orientation for random period of time and then unfreeze. Hours or days I would never know. If it was in landscape and I needed it in portrait I could just reboot and it would revert to portrait but not the other way around. It's been struck for 3 or 4 days now in portrait and now a new bugmhas appeared. Setting the hardware button to mute works fine, but still the software orientation button is useless. Only now, if I switch then hardware button to orientation lock, it tells me I'm muted and I'm orientation locked at the same time. And the software button works for the mute now. Need help. Thanks.

In other words, can I have my screen rotate automatically as I hold my iPad in either portrait or landscape AND hear sounds from my apps at the same time?
Yes, you can. You can configure the Side Switch (above the volume button) either as Mute switch or Rotation lock.
Settings > General > Use Side Switch to: choose what you like the Side Switch to function as.

Does the sound of your caller get reduced when you speak at the same time?

Hi everyone,
I'm noticing some strange behaviour of my iPhone 3G's audio on the O2 network here in the UK. Both O2 & the iPhone are new to me so I don't know which is the cause, but was wondering if anyone else has experienced this 'problem'? What happens is this:
When I'm on a call with my ear to the iPhone's earpiece (or using headphones) & I speak whilst the caller is speaking (or let's say I'm chatting to my wife in the same room as me whilst I'm listening to 'hold music'), I've noticed that *the volume & call-quality of the incoming line is often reduced*.
Initally this might not seem a problem, BUT, there have definitely been a view times when I've been in a noisy environment (such as street traffic, or my kids shouting & playing in the background) where I've missed things that the caller told me. In both these situations, I've noticed that the caller's voice has got quieter, sounded 'grainy' or even sometimes gone totally quiet until the sound from me (or my environment) has stopped. The 'problem' seems to right itself a minute or so of the call, but that's little consolation to the first 60 seconds of the call!
It's most noticeable on headphones by the way; As a test, I plugged in regular headphones to my iPhone (i.e. not the iPhone IEMs with the mic), called a landline phone-line with a pre-recorded message, then spoke into the iPhone's built-in microphone. Every time I did this, the incoming audio signal was 'turned down' &/or sounded gritty, then returns to normal when I (or my background noise) went quiet.
I don't think this is a fault with my phone. but more either an iPhone 3G hardware 'characteristic', v2 software bug, or network issue. (O2 said they've never heard of this before of course...)
If anyone else has the time to try this out please, I'd appreciate it
Thanks,
Jason

Hi Quickdraw,
Thanks for your reply.
I don't know this for sure, but I think it has EVERYTHING to do with bandwidth.
Yes, that makes a lot of sense... I was making calls on 2G/Edge at the time of my 'tests' rather than 3G, partly due to battery-saving but also that 2G still has much better coverage over here (just as you guys in the States seem to be experiencing).
I've done some more tryouts today, & noticed that if the 2G signal is really strong, OR if I switch to 3G & have a reasonable-to-good reception, the 'incoming-signal-dropping-out-when-I-talk' doesn't happen much at all...
So, the bandwidth thing does make sense, but it's interesting/annoying that it manifests itself as "one good-quality voice OR the other", rather than "full-duplex-but-not-so-great-for-both-voices" sound...
If anyone in the UK can feed back their experience with O2, I'd appreciate it please. (I never had this issue in the 10 years I was with Orange..)
Cheers,
Jason

How to unmute and disable rotation lock the ipad 2 at the same time?

I can't seem to unmute without enabling the rotation lock, and vice versa. I want to unmute and disable the rotation lock. Resetting the settings doesn't work. It's really fustrating. Help?

The side switch is the key. Depending on your settings, it may affect the mute or it may affect the rotation lock. Whichever function it supports, the other function is performed by a "soft switch." This support article from Apple provides detail.
http://support.apple.com/kb/HT4085
In case you're wondering, here is the history. Originally, the mechanical switch affected only the rotation lock and the mute was a software switch elsewhere. In IOS-3, it was changed to be the mute switch and the rotation lock became a software switch. This was done to ensure consistency among IOS devices. Unfortunately, a large quantity of users complained loudly, alleging that they turned the rotation lock on and off several times every hour and the convenience of the mechanical switch is essential. In IOS-4, Apple bowed to the whiners and made the switch function selectable and now we're stuck with a mess.
