Ipod locking issue

I have a 5th gen ipod using windows xp. I know I don't have the latest version of itunes but I don't think that should matter. When I tried playing it..nothing happened...just a blank screen. I hooked it up to my pc to charge in case that was the issue. When I charged and safely ejected the ipod it showed that it was locked even though the hold button was in the off position. No matter what I do it stays locked. I tried holding the select and menu button but that didn't work. Any other suggestions?

This might not be the solution but it's always a good place to start.

Audio Books Not Resuming / Ipod locks if exit Music after 2.2.1 Upgrade

Hello,
I have a 1G 16GB Ipod Touch, and have been running 1.1.4 for the past year until about a week ago when I took the plunge and upgraded to 2.2.1. I thought all went well, but have been experiencing multiple problems as my use of the Ipod expands.
I subscribe to Audible and listen to long audio books on my drive to work. In 1.1.4 I was able to pause the books, go off and do other things, and come back to resume where I left off. This feature no longer works correctly for me after the 2.2.1 upgrade.
After pausing an audio book, I am able to resume playback where I left off if I stay within the Music application (even playing other songs or books). However, if I exit the Music application back to the Main Menu, the Ipod locks for about 30 seconds before I can start another app, lock, or go back into music. If music is playing when I go back to the Main Menu, it will continue during this time the Ipod is locked and then stop. If no music is playing, the Ipod still locks, so it doesn't matter if music is playing or not.
After the Ipod becomes responsive again, I can go back into Music, but I find that all my audio books have reverted back to the bookmarks that existed a week ago when I did the upgrade. For example, I was on Chapter 6 of a book when I did the upgrade, listened up to Chapter 10 and paused. I exited the Music, came back in, and it reverted to the exact second in Chapter 6 where the bookmark was placed before the upgrade. I have tried multiple experiments with this, and it's always the same result. I upgraded to 2.2.1 to use Apps, so it stinks that I can't leave Music...ever.
Is there anything that I can do to fix this issue or am I going to be forced to downgrade back to 1.1.4?
Thank you very much!

Well, I managed to fix the problem thru sheer brute force so I figured I would at least pass along what I did in case someone else has this issue. Evidently, doing an in-place upgrade does not work so as a last resort I used "Restore", cleared the Ipod, reloaded everything back on and the playback positions are now working again in music and video. Something screwy must have happened during the upgrade and just needed to start over. Still trying to reload everything (they REALLY need a mass backup feature for photos/music/videos) but looks like it will work.

HT1414 ipod locked up because forgot password and back it up to restore and now it comes up with "ipod cannot be restored error occured 2009" can you help me?

My Ipod locked up because I forgot my password when it opened to the lock screen and it then said IPod disabled connect to itunes. When we did that it asked to restore did that and backed up my ipod then restored. Now it says "IPod connect be restored and unknown error has occurred 2009". What do we need to do now"? Can someone please help?

Error 2000-2009 (2001, 2002, 2005, 2006, 2009, and so on)
If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604 above. If the issue persists, it may be related toconflicting security software. If the errors persist on another computer and known-good USB cable, the device may need service.
The "device may need service" means a hardware problem. In that case make an appointment at the Genius Bar of an Apple store.

"Uknown Library" after iPod locked up

I connected my iPod this morning to charge the battery. The message "Do not Disconnect" appeared and the iPod locked up. I resolved that issue, but know I have an UKNOWN persons library in my iTunes, have no clue who it is or have never downloaded the songs that are in the library. Does anyone know how it got there? How to get rid of it? Or should I be concerned about someone hacking my iTunes/PC, etc? I did create an account in the iTunes Store and downloaded music for the first time earlier this week, don't know if that has anything to do with it. Thanks in advance for any advice!

Report Designer Locking issue

Hi,
We have found locking issue while accessing same report(Created in Report Designer) by multi users at a time .
Has anyone face this issue and How to fix it. It's major concern because same report can be accessed by multiusers at same time
Thanks
Siva

Siva,
only one person at a time has permission to open the report in the Report designer - just like with Queries in the query designer. This should not have any effect on you actually executing the report in the portal - multiple people can do it then.
this is a security issue that other software vendors use as well - just like you cannot open any MS Office files on the network for editing that someone has opened already.
Thanks

Locking issue in workflow with conseutive database update

Dear Workflowers,
We are in ECC 5.0 and release 6.40. We went live for SAP in February and we are currently using workflow in PLM module for DMS and ECM.
We have been facing this locking issue randomly happened in our production and quality system. The error from workflow log is "Document XXXX is locked by WF-BATCH". I have two steps in workflow one is to update the document user( from originator to editor with custom BO "zdraw" new method "setuser") and the next step is to update the document status( BO "zdraw" "setstatus" method which inherited form standard BO "draw").
I have tried to use "wait" (1st try) , statements "BAPI_DOCUMENT_ENQUEUE", "BAPI_DOCUMENT_DEQUEUE" (2nd try) and "Commit work and wait" (3rd try) to add one step in between, however the issue remains.
The other question I had was we need to write "commit work" when we use BAPI to perform database update in the ABAP program. But I don't see "commit work" in the method of BO(for example "setstatus" in "draw" object) which performs database update. How does workflow perform DB update properly without "commit work" by referencing standard method?
Could anyone please share your expertise with the issue I am facing?
Thank you in advance,
Merta

Hi Merta,
Regarding COMMITs: theoretically you should never use COMMIT statements because the Workflow runtime handles that - the transaction of executing the task is the LUW, not your method. By adding COMMIT WORK you are also committing the workflow task execution.
In practice however there are the occasional exceptions where something just won't work without an explicit commit - but the theory remains that you should always try it without.
Regarding your problem, the one way to be certain that a DB update is complete is to use a terminating event - either through change documents or status management.
Failing that, you can write a wrapper method for SETSTATUS that does something like:
do 10 times.
try to lock it.
if success.
    unlock.
    swc_call_method self 'SetStatus' container.
    set success flag.
else.
    wait up to 3 seconds.
endif.
enddo.
if no success, raise exception.
Cheers,
Mike

Locking Issue in Planning DSO in SAP BW 7.3(Integrated Planning)

Hi Experts,
We have built Aggregation Level on Direct Update (planning enabled) DSO and used the same in the input ready queries.( Its complete Manual planning - new row addition feature in WAD).
We have 5 characteristic and one key figure for planning.
We are facing lock issue while planning the data i.e. when one user is planning, other user cannot plan.
The lock relevant characteristic is Column A and the same has been added to the Lock Characteristic tab(RSPLSE) of the infoprovider. The input ready query is also restricted with a variable on Column A (manual input single variable- mandatory).
While the user opens the Planning Layout and plans the data, we can see lock entry in RSPLSE(locks tab) for the Column A selection in the infoprovider, yet if another user is trying to plan for data for some other selection of Column A, a lock entry in RSPLSE is shown with the selection but it errors in thelayout with lock on the infoprovider and cannot plan the data.
Any inputs will be of great help.

Found the answer.
We had used the Planning Function directly in the WAD layout before saving data without filter.(basically to check some condition).
Created the Planning Sequence with Column A filter on the Aggregation level and used the same sequence before saving the data in WAD
Issue resolved.

[ADF-11.1.2] Locking issue with SQL 92

I see one Locking issue with SQL92 Oracle ADF Application.
ADF Version: [ADF-11.1.2]
Database: Oracle 10g Express Edition
Situation 1:
With Following setting:
File: Application Resource > Description > ADF META-INF > adf-config.xml

      </amconfig-overrides>
    </startup>I have a page showing record 'x' of view object. I open same record on another page. Now I have same record showing on two different tabs of browser.
1. I modify first record and save it. It worked... Got commited to database.
2. I goto second tab and modify same record and tried to same it. It throws me an error - Another user has changed the row with primary key oracle.jbo.Key[38 ] . As expected...
3. I then, reopen the same record on 3rd tab of browser. Modify it and tried to save it. It just hang... as if it is processing the record endlessly.
If I see the Log:

Can any one please tell me, what is the issue with SQL92 setting ?
Edited by: Anandsagar Sah on Mar 11, 2012 8:10 AM

The framework works correctly in the Situation #1. Please, note that the locking statement in this case is "SELECT ... FOR UPDATE", but not "SELECT ... FOR UPDATE NOWAIT" (as it is in the Situation #2). When you entered the 2nd tab and tried to update the row, then the framework executed the locking statement and the row was locked (and it remained locked because the framework detected that another user had modified the row, so it stopped the processing and no COMMIT operation was executed). When you entered the 3rd tab and tried to update the row, then the framework tried to lock the row againg, but the locking statement was blocked by the existign lock and it started waiting on the lock from the 2nd tab. So this is expected behaviour.
The interesting question is why you do not get any error in the Situation #2. In my opinion you should get an error because the locking statement from the 3rd tab should fail immediately (because the row should have been locked from the 2nd tab and the locking statement is with NOWAIT option). I suspect that when the DB is Oracle and you use Oracle SQLBuilder, then the ADF issues a DB savepoint at the beginning of the DML operation and rolls back to the savepoint is a case of some failure, so the 2nd tab has not left any lock. You can check this by setting on SQL trace on the DB server.

Purchase order locking issue

Hi ,
We are processing IDoc. The IDoc FM does GR of STO by using MIGO transaction via BDC , then FM also does GR of STO Delivery number by using VL02N transaction . MIGO transaction is successful but while doing GR of STO Delivery number via VL02N we are getting an error like ' Purchase order XXXXXXXXXX is currently locked by user XXXXXX .
This happens if we process the IDoc in background . If I process the IDoc in foreground by putting breakpoint at MIGO and VL02N , it executes successfully .
I feel it is a locking issue . I tried using FM DEQUEUE_ALL , MM_DEQUEUE_DOCUMENT after MIGO but it did not work out .
Please suggest for any pointers on this locking issue .
Regards,
Kiran.

Forget about WAIT statement.
Use:
set update task local.
...before starting MIGO.

FOR UPDATE cursor is causing Blocking/ Dead Locking issues

Hi,
I am facing one of the complex issues regarding blocking / dead locking issues. Please find below the details and help / suggest me the best approach to ahead with that.
Its core Investment Banking Domain, in Our Day to day Business we are using many transaction table for processing trades and placing the order. In specific there are two main transaction table
1)     Transaction table 1
2)     Transaction table 2
These both the tables are having huge amount of data. In one of our application to maintain data integrity (During this process we do not want other users to change these rows), we have placed SELECT …………….. FOR UPDATE CURSOR on these two table and we have locked all the rows during the process. And we have batch jobs (shell scripts ) , calling this procedure , we will be running 9 times per day 1 hrs each start at 7:15AM in the morn finish it up in the eve 5PM . Let’s say. The reason we run the same procedure multiple times is, our business wants to know the voucher before its finalized. Because there is a possibility that order can be placed and will be updated/cancelled several times in a single day. So at the end of the day , we will be sending the finalized update to our client.

Can anyone suggest me , like how can rectify this blocking /Locking / Dead lock issues. I wants my other application also will use this tables during these process.

Delivery Document Lock Issue in Z Program using BAPI(s)

Hi,
I am a functional consultant posting this in ABAP forum. We have developed a Z-Program.
User enters the Service Order no. in this program and executes it.
The program then updates the following linked documents in the following sequence using BAPI(s)
Outbound Delivery
Service Notification
Service Order (This is done using BDC of IW32)
It sometimes happens that once the Program reaches the iw32 bdc, it gives error "Delivery XXXXXXXX is locked by User ID XXXXXX"
The user ID being that of the person executing the transaction.
This happens like 3 out of 100 times in the Production Server. We are unable to replicate this issue in Quality or Development Server.
We believe it to be a performance issue (database updating is slow)
However Client wants us to investigate the Program and see what is possible.
We are thinking of putting WAIT after the BAPI(s) of the Delivery Update.
Any suggestions, please help.

Hello Suhas,
Thanks for the reply.
These documents are seperate objects but are interlinked. i.e I can see in the Document Flow for Service Order, which is the Service Notification and Outbound Delivery for the Material.
Also, If I'm in change mode in the Outbound Delivery, I cannot go into the change mode of the Service Order.
Yes, we are using BAPI_TRANSACTION_COMMIT after each BAPI in the Program. We have used the Wait Statement in all BAPIs for the Service Notification. These BAPI(s) are before the IW32 BDC.
I am copying code from one of the commit BAPI(s)
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
                EXPORTING
                  wait = c_x.
              WAIT UP TO 1 SECONDS.
I noticed in the Outbound Delivery BAPI(s) (two of them) don't have the wait in the BAPI_TRANSACTION_COMMIT. Hence I though if we add this, could this resolve the issue?
Service Order gets updated last through BDC for IW32 after all the BAPI(s) are executed for Outbound Delivery and Service Notification.
I understand WAIT would increase processing time, that is why I am posting this to know if we have some other solution available for such a lock issue.

Row locking issue with version enabled tables

I've been testing the effect of locking in version enabled tables in order to assess workspace manager restrictions when updating records in different workspaces and I have encountered a locking problem where I can't seem to update different records of the same table in different sessions if these same records have been previously updated & committed in another workspace.
I'm running the tests on 11.2.0.3. I have ROW_LEVEL_LOCKING set to ON.
Here's a simple test case (I have many other test cases which fail as well but understanding why this one causes a locking problem will help me understand the results from my other test cases):
--Change tablespace names as required
create table t1 (id varchar2(36) not null, name varchar2(50) not null) tablespace XXX;
alter table t1 add constraint t1_pk primary key (id) using index tablespace XXX;
exec dbms_wm.gotoworkspace('LIVE');
insert into t1 values ('1', 'name1');
insert into t1 values ('2', 'name2');
insert into t1 values ('3', 'name3');
commit;
exec dbms_wm.enableversioning('t1');
exec dbms_wm.gotoworkspace('LIVE');
exec dbms_wm.createworkspace('TESTWSM1');
exec dbms_wm.gotoworkspace('TESTWSM1');
--update 2 records in a non-LIVE workspace in preparation for updating in different workspaces later
update t1 set name = name||'changed' where id in ('1', '2');
commit;
quit;
--Now in a separate session (called session 1 for this example) run the following without committing the changes:
exec dbms_wm.gotoworkspace('LIVE');
update t1 set name = 'changed' where id = '1';
--Now in another session (session 2) update a different record from the same table. The below update will hang waiting on the transaction in session 1 to complete (via commit/rollback):
exec dbms_wm.gotoworkspace('LIVE');
update t1 set name = 'changed' where id = '2';
I'm surprised records of different ids can't be updated in different sessions i.e. why does session 1 lock the update of record 2 which is not being updated anywhere else. I've tried this using different non-LIVE workspaces with similar results. I've tried changing table properties e.g. initrans with and still get a lock. The changes to table properties are successfully propagated to the _LT tables but not all the related workspace manager tables created for table T1 above. I'm not sure if this is the issue.
Note an example of the background workspace manager query that may create the lock is something like:
UPDATE TESTWSM.T1_LT SET LTLOCK = WMSYS.LT_CTX_PKG.CHECKNGETLOCK(:B6 , LTLOCK, NEXTVER, :B3 , 0,'UPDATE', VERSION, DELSTATUS, :B5 ), NEXTVER = WMSYS.LT_CTX_PKG.GETNEXTVER(NEXTVER,:B4 ,VERSION,:B3 ,:B2 ,683) WHERE ROWID = :B1
Any help with this will be appreciated. Thanks in advance.

Hi Ben,
Thanks for your quick response.
I've tested your suggestion and it does work with 2 workspaces but the same problem is enountered when additional workspaces are created.
It seems if multiple workspaces are used in a multi user environment, locks will be inevitable which will degrade performance especially if a long transaction is used.
Deadlocks can also be encountered where eventually one of the sessions is rolled back by the database.
Is there a way of avoiding this e.g. by controlling the creation of workspaces and table updates?
I've updated my test case below to demonstrate the extra workspace locking issue.
--change tablespace name as required
create table t1 (id varchar2(36) not null, name varchar2(50) not null) tablespace XXX;
alter table t1 add constraint t1_pk primary key (id) using index tablespace XXX;
exec dbms_wm.gotoworkspace('LIVE');
insert into t1 values ('1', 'name1');
insert into t1 values ('2', 'name2');
insert into t1 values ('3', 'name3');

My ipod locked and i cant remeber the password how can i open it and change the password?

my ipod locked and i forgot the password is there anyway i can open it without haveing to reboot the whole ipod to factory settings.

Hey 1966Gt6,
I found an article that goes over what to do if you've forgotten or can't remember your passcode. Check it out here:
iOS: Forgotten passcode or device disabled after entering wrong passcode

My Ipod lock screen has disappeared!

My iPod lock screen has disappeared and says the iPod is disabled. I had a passcode and I have tried turning it on and off and when I plug it into iTunes it says I need to unlock the iPod first! But the passcode 'slide to unlock' bar is gone!
HELP!

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
