Enqueue locking/unlocking

We are an SAP education/training facility associated with the SAP University Alliance. With previous versions of SAP 4.6, 4.7 there were built-in programs called ZSENQOFF and ZSENQON for turning off the Enqueue locking mechanism and turning it back on. This was necessary so multiple students could do company code customizations at the same time. These programs, although they exist in the ECC 6.0 version, no longer function. Could somebody provide me with programs which will work in the ECC 6.0 version.
We are running Windows/Oracle environment.
Thank you

SAP has developed a programme named "ZSENQOFF" which disables the
locking of tables. This is sometimes used in training clients to disable the enqueue functionality that causes the lock. This should not be used for any other clients. The programs were delivered with an IDES installation.
There is no actual documentation for this report as it was only developed as an extra option for training purposes. This report is client dependent.
These reports are released only for SAP-Intern and not on a customer's system to be used. This is, therefore, present only in the internal SAP-Trainerguides. Moreover there are cases wherer database inconsistencies caused by faulty operation of this Reports which are not covered by the SAP Support .
These reports may be present in IDES ECC 6.0, but they can't be used i guess.
There is no alternative solution for this.
Hope this clarifies.

Enqueue/Dequeue - Locking/Unlocking object

Hi all,
Please help me working with this enqueue/dequeue command. What I'm trying to do is to lock a Service Order. My requirement is to do a BDC for the Service Order Settlement Rule. So after hitting SAVE, a secondary process will be kicked off to perform my BDC for the same order. Now what Im doubting is that what if user re-enter the same Service Order again so quick. So my BDC program will not be performed immediately since it will be locked by the usser.
So my idea is to lock it first while my BDC program is still running. Any help please? Thanks.

Nope. Just 1 BDC -on my 2nd program only. Or to make it simple, I have modified ZXWOCU07 (IWO10009) to perform/kick off a call function( this is being triggered after hitting on SAVE). And this FM contains my checking if SO is now open for change then do the do the BDC.
What I'm thinking is to lock first the SO to block any user from accessing that SO, so it will do the BDC first. But I'm not yet familiar with the locking/unlocking of objects. Please help me on how to use enqueue or locking object.

Auto Lock/Unlock is not working when the iPad cover is closed or opened for iPad 4 with retina display after upgrading to ios7.

As the title above, is there any solutions for that? I tried restarting my Ipad and i've double checked the auto lock/unlock button is on.

I have the same problem also. Restarting isn't helping and the auto lock/unlock button is on. Plus a couple of time when I turn it on it is asking if I want to power off. That is when I push the button on the front to wake it up. Not the power button on top. I have an IPAd 2. Worked fine before the update.

Window not refreshing after lock/unlock screen.

I've noticed an issue where if I lock the screen (windows key + L) before the visible property of some component is changed, then unlock the screen, the component visibility is not updated until I mouse over the JavaFX application window.
I'm including some sample code to demonstrate the problem. To use:
1. Run.
2. Click the button.
3. Lock the screen.
4. Wait 15 seconds.
5. Unlock the screen, but do not touch the mouse.
6. Verify that the progress indicator animation is still visible, but is not animated.
7. Mouse over the application window.
8. Verify that the progress indicator disappears.
In addition, if steps 3-7 are not executed, the behavior is as I would expect... The progress indicator disappears 15 seconds after the button is clicked.
Does anyone have any ideas on a workaround that would force a UI update when the screen is unlocked?
I'm using the version of JavaFX packaged with Java 1.7.0_09

I would like to understand why during loads we were no able to run those select statements, statspack schedule snapshot reports were not able to finish, also automatic
database statistics... why 5 for update statements locked the whole DB?

"WAITED TOO LONG FOR A ROW CACHE ENQUEUE LOCK" happens when it needs to acquire a lock on data dictionary. Did you check the trace file associated with the statement?The trace file is too long, which information I need to focus more?

Error: WAITED TOO LONG FOR A ROW CACHE ENQUEUE LOCK! pid=26

Hi every one,
Today, i met a problem: Application cannot connect to database because database hang ( I also cannot connect to database with sqlplus) . Check alert log, only one error:
WAITED TOO LONG FOR A ROW CACHE ENQUEUE LOCK! pid=26This error not only appear first time, but also happen every one month. I must reset server for database release all memory but I think It isn't a true solution!
Could you give a recommend for this.
Regards.

The Row Cache is actually the Data Dictionary Cache. It is where definitions from the data dictionary (tablespaces, objects, users etc) are loaded into memory.
There would be an associated trace file written with the occurrence of this warning.

Password file gets changed when an account is locked/unlocked in 9i !!

Hello All,
I observed that in 9i (9.2.0.8 and 9.2.0.6 on Solaris 9), the timestamp of the orapw<SID> file changes when a non-sys account is LOCKED/UNLOCKED. There is no change in the size of the file, but timestamp alone gets changed to the time the account is locked/unlocked.
orapwd<sid> stores the password for administrative accounts, what has it got to do with non-sys accounts( an account with just create session privs ) ?
Is it the expected behaviour ?
TIA,
John

Hi,
You can create a user defined metric which will query the table "dba_users" and check for "account_status" and will alert you whenvr usr is locked.
You can find the link for creating "user defined metric" at "Related Links" section at the bottom of database homepage in OEM.
Hope this helps...

Faulty Lock/unlock button, any service centers other than apple store?

I bought my iPhone 5 in Malaysia and now I am in Moscow, my phone's lock/unlock button isnt sensitive since last week. Since it is still under warranty, can i send it for repairs here in Moscow? But we dont have any apple stores here. What should i do? Can I still get it repaired in Moscow for free? How long does it take to repair this?

You need to return to Malaysia for warranty service.

C3-01 Touch and Type Keypad Lock/Unlock Issue,,

I just bought this C3-01 touch and type phone and it got big issue of locking/unlocking key pad..
phone gets locked and even if I click on keylock button and then click unlock (on touch screen) then it never gets unlocked.. (I checked guide it says same thing)
how to resolve this issue? anyone had same issue?
Solved!
Go to Solution.

1st Of All, If u just got oyur Nokia C3-01 Device, then You must be having the old version of SOftware in it, maybe v05.68. So In that SW, You have to press the unlock, there is no swipe to unlock,
So, You can clearly see, there is a Button at the Right of your mobile below the Volume Buttons (Right If you Have your Device Screen Facing you, Left If you ahve the Back Battery Cover Facing You)
So Press that Button, you will see your display glow showing " UNLOCK " option in the middle, Press It.
It will get Unlock.
Also, after Unlocking, Before adding anything to Phone Memory (like contacts, messages,etc) make sure to update your Mobile FW/SW to the latest version out there (which is v06.05)
So, If you have a PC with internet connection, connect your Device with USB, and Use Nokia Software Updater (Or Nokia Ovi Suite, whatever you have got Installed In your PC) and Start Updating ASAP, Alot Of Bug Fixes have been Taken Place,
If Still Not Unlocked, RETURN YOUR DEVICE NOW, because your Device is Faulty.

(V7.X ~ V8.X) OPS 환경의 WAIT EVENT DFS ENQUEUE LOCK ACQUISITION에 대하여

제품 : ORACLE SERVER
작성날짜 : 2004-08-13
(V7.X ~ V8.X) OPS 환경의 WAIT EVENT DFS ENQUEUE LOCK ACQUISITION에 대하여
=========================================================================
PURPOSE
이 자료는 OPS 환경에서 V$SESSION_WAIT 뷰에 나타나는 'DFS lock
acquisition'과 'DFS enqueue lock acquisition'에 의하여
performance가 저하될 경우 해결책에 대하여 알아보기로 한다.
SCOPE
Oracle Parallel Server(OPS) Option은 7~9i Standard Edition에서는
지원하지 않는다.
Problem Description
OPS 환경에서 많은 user들이 동시에 접속하려 할 때 connection이
매우 늦어지면서 V$SESSION_WAIT 뷰에는 'DFS lock acquisition'과
'DFS enqueue lock acquisition' 이라는 event가 나타나며 slow
performance를 보이는 문제가 발생한다.
Workaround
none
Solution Description
데이타베이스에 동시에 로그인하는 user의 수를 근거로 sequence sys.audses$
의 cache_size를 더 큰 값으로 증가시켜야 한다.
예를 들어, 200 으로 증가시켜 본다. (default value is only 20).
sequence sys.audses$의 cache_size를 변경하기 위해서는 다음과 같이 수행한다.
SQL> alter sequence sys.audses$ nocache;
SQL> alter sequence sys.audses$ cache 200;
변경된 값을 확인하기 위해서는 다음과 같이 수행한다.
SQL> select * from dba_sequences where sequence_name='AUDSES$';
Explanation
로그인을 하는 동안 모든 데이타베이스 user들은 audit session id를 retrieve
하기 위하여 sequence sys.audses$를 액세스할 필요가 있다. Default로 20개의
sequence만이 cache되기 때문에 DFS enqueue lock에 높은 concurrency가 일어난다.
이것은 OPS 환경에서만 발생하는 문제인데, 이 event 하에 발생하는 lock들은
Parallel Server mode 에서만 발생하기 때문이다. 그래서, 이 때에는 반드시
DLM에 의해서 lock convert operation이 일어나야 한다.

Entity Lock Unlock issue

Dear All,
We are facing one issue with locking and unlocking of entities
Locking of period from April to February (11 months) 1100 entities takes 40 seconds - We lock top parent and last period February
Unlocing top most parent for single month of February (Last locked period) takes 840 seconds
Java heap file parameter is set to optimum
Othe HFM application on same server does not give such problem
Further this happens on development server and on production everything is fine with the same application (It does not take such long time)
Environment is Windows 2003, HFM Version 9.3
Can anyone please guide on the same
Thanks
Payous999

While I don't have a solution to this I can also vouch to the same odd behaviour.
In our Dev environment, lock / unlock are not too different in timing; however in production unlocking takes a significantly longer amount of time.
As our dev environment sees practically no activity, I would think that perhaps the issue has something app utilization? One way to test this I guess would be to restart the app over a weekend and do a quick test of lock / unlock time before users get into the system?

APO: Interactive Demmand Planning - LOCK/UNLOCK Planning Book

Hi forum,
I need to lock temporaly a Planning Book in /SAPAPO/SDP94 in order to avoid users to be logged as a loading process is running
do you know any standard transaction to do this or have another idea?
thanks in advance

Thanks for your answer, Uma!
I was testing Bapis that you mentioned and I think it's a radical solution because I would be blocking users, I just want to lock a planning book (users can keep logged in the system)
Transaction /n/sapapo/sdpplbk does not guarantee that user can access to planning book (if he/she is smart )
any suggestion?

Hi Cesar/Rasec,
If I understand correctly you want users not to change any data while some background job is being run. One way to handle this would be to lock and unlock the concerned planning area. This will prevent any users from making changes to the data in the planning area which should also mean your background job will not fail due to locks on data selection by users.
For this you can develop customization to do locking and unlocking of the planning area. The function module ENQUEUE_/SAPAPO/E_PAREA can be used to lock planning area while DEQUEUE_/SAPAPO/E_PAREA to unlock the planning area.
Hope this gives you some direction.
Thanks,
Somnath
