JPasswordField locking issue in linux

Hi,
password field is working good if its alone in the panel/frame. if added textfield for username before password field, password field is locking and its never allowing to enter the data. this issue is in linux.* the same code works well in windows platform. is this a bug? i am using latest jre though....
public class test3 extends JFrame implements ActionListener
    JTextField txtUserName=new JTextField(10);
    JPasswordField pwd = new JPasswordField(10);
    public test3()
         setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         getContentPane().setLayout(new GridLayout(2,1));
         getContentPane().add(txtUserName);
     getContentPane().add(pwd);
     txtUserName.addActionListener(this);
     pwd.addActionListener(this);
     pack();
     setVisible(true);
    public void actionPerformed(ActionEvent e)
         System.out.println("UserName=" + txtUserName.getText());
         System.out.println("Password=" + pwd.getText());
    public static void main(String arg[])
         new test3();
}My environment...

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.

Priyanka

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
    <startup>
      <amconfig-overrides>
        <config:Database jbo.SQLBuilder="SQL92" jbo.locking.mode="optimistic"/>
      </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:

That's it.. nothing happens further.. If I execute above query on SQL Worksheet, it doesn't come up with the result. Just hang for something...
SELECT ID, CI_ID, COLUMN_NAME, DISPLAY_COLUMN_NAME, COLUMN_VALUE, CREATE_DATE, CREATE_BY FROM ESUSER.CI_AUDIT WHERE ID='38' FOR UPDATE I can execute above query for other record of same table but not '38'. Even if I fire commit command to database, it is not working.
I have to restart the database services to bring everything to normal state.

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.

Now the issues is :
When these Process runs, our other application jobs failing, because it also uses these main 2 tranaction table. So dead lock is detecting in these applications.
Solutin Needed :
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');
commit;
exec dbms_wm.enableversioning('t1');
exec dbms_wm.gotoworkspace('LIVE');
exec dbms_wm.createworkspace('TESTWSM1');
exec dbms_wm.gotoworkspace('TESTWSM1');
update t1 set name = name||'changed' where id in ('1', '2');
commit;
Session 1:
exec dbms_wm.gotoworkspace('LIVE');
update t1 set name = 'changed' where id = '1';
session 2:
exec dbms_wm.gotoworkspace('LIVE');
update t1 set name = 'changed' where id = '2';
--end of original test case, start of additional workspace locking issue:
Session 1:
rollback;
Session 2:
rollback;
--update record in both workspaces
exec dbms_wm.gotoworkspace('LIVE');
update t1 set name = 'changed' where id = '3';
commit;

update t1 set name = 'changed' where id = '3';
commit;
Session 1:

User Lock issue when processing IDOCS

Hi Folks,
We are pushing the data into SAP using IDOCS.During this process some IDOCS are getting failed due to User Lock on shipment header.Anyone here can share their experience in dealing with User Lock issues.
Thanks,
Kiran.

Kiran,
Only one can edit the document, it's standard fucntion. I think No note can resolve this. I can suggest you to run a back ground job very frequently ,which picks these status 51 IDOCs and reprocess. Report is :RBDMANi2
We can use Message class & error message number on selection screen, so that we can make sure that only those idocs which were failed due to Lock problem are taken by the job.

Blocking/locking issue

I need to find out what is the besy way to resolve blocking/locking issue in the database in case of when users are complaining his processes is hanging for last many hours.
I tried to find out the actuall process that cause blocking by running queries against dba_blockers and dba_waiters but my queries also hanging since last several hours.
I killed my own session and ran the query against these views but nothing coming back. Please let me know if I should be looking at something else than dba_blockers or dba_waiters
Any idea why I am NOT getting anything back? Please let me know what is the best approach to resolve this issue.
Your help will be greatly apprciated .
Thanks
Steve

Try the following :
To identify locked objects :
SQL> select object_name, v.session_id SID, v.oracle_username,type,lmode,request
2 from v$locked_object v, v$lock l, dba_objects o
3 where l.sid=v.session_id
4 and v.object_id=o.object_id
5* and l.block > 0;To identify who locks whom :
SQL> select
2           (select osuser from v$session where sid=a.sid) blocker,
3         a.sid,
4           (select serial# from v$session where sid=a.sid) serial#,
5        ' blocks ',
6         (select osuser from v$session where sid=b.sid) blockee,
7             b.sid, c.username username
8    from v$lock a, v$lock b, v$session c
9 where a.block = 1
10     and b.request > 0
11     and a.id1 = b.id1
12     and a.id2 = b.id2
13*    and b.sid = c.sid;

Windows 2008 R2 Screen Lock Issue (GPO)

Scenario: We will be deploying POS machines at our stores that will have Windows 2008 R2 as the preferred OS. The function of this POS machine is for POS administration and not for ringing up sales. The machines have been configured to autologin a specific
user via GPO for POS functions. Also, a specific POS desktop environment shell has been configured to launch instead of Explorer (explorer.exe) shell environment at autologon.
Everything seems to be working as expected except for the session of the user locking. Since the POS environment needs to be up at all times with the specific user profile, we do not want the OS to lock the user session. I've timed it and it seems to lock
the screen (not log off) at approximately 15 minutes of inactivity, we do not want this.
So far, these are the GPOs I have configured that have not fixed the issue:
Computer Configuration>Policies>Windows Settings>Security Settings>Local Policies>Security Options>Microsoft Network Server: Amount of idle time required before suspending session = 99999 minutes
Computer Configuration>Policies>Administrative Templates>System>Power Management>Sleep Settings>Allow applications to prevent automatic sleep (plugged in) = Enabled
Computer Configuration>Policies>Administrative Templates>System>Power Management>Sleep Settings>Require a password when a computer wakes (plugged in) = Disabled
Computer Configuration>Policies>Administrative Templates>System>Power Management>Sleep Settings>Turn off hybrid sleep (plugged in) = Enabled
Computer Configuration>Policies>Administrative Templates>System>Power Management>Sleep Settings>Turn on the ability for applications to prevent sleep transitions (plugged in) = Enabled
Computer Configuration>Policies>Administrative Templates>System>Power Management>Video and Display Settings>Turn off the display (plugged in) = Enabled = 99999 seconds
User Configuration>Policies>Administrative Templates>Control Panel>Personalization>Enable screen saver = Disabled
User Configuration>Policies>Administrative Templates>Control Panel>Personalization>Password protect the screen saver = Disabled
User Configuration>Policies>Administrative Templates>System>Ctrl+Alt+Del Options>Remove Lock Computer = Enabled
User Configuration>Preferences>Windows Settings>Registry>HKCU>Control Panel>Desktop>ScreenSaveActive = 0
What are we doing wrong? How do I configure the OS to not lock the user session but keep it active at all times?
As a side note: We have Windows 7 POS machines also that will be ringing up sales that we do not have the screen lock issue.

Hi,
>>Please see my setting indicated in my original post. We have Turn Off the Display set to 99999 seconds.
I understand that we have set the Turn Off the Display for this amount of time. However, just for double check, we can go to the power plan we are using to check if the setting has been applied successfully. If the setting has been applied successfully,
it should be grayed out. Or, we can run command gpresult/h gpreport.html
with admin privileges to collect group policy result report to check this.
Besides, do we use other third party software to protect our computer? We can try to clean boot the server to see if the situation persists.
Regarding how to perform a clean boot, the following article can be referred to for more information.
