• Failure to get the db line lock: ORA-01157

  Hello

  I have a client that uses that the customer is using Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production with the partitioning, Real Application Clusters, Automatic Storage Management. An application has been installed recently in which scripts created a .dbf file instead of save on the disk group. So if I run the query I see the following output below

  SQL> select name from v$datafile;
  NAME

  +RIAMSTG_DBF1/riamstg/datafile/oamstg_mds.259.821014833

  /db/oracle/112/db/dbhome_1/dbs/rbacx.dbf
  

  Now, when we reboot the DB we see the error below.

  ORA-01157: cannot identify/lock data file 18 - see DBWR trace file
  ORA-01110: data file 18: '/db/oracle/112/db/dbhome_1/dbs/rbacx.dbf'
  ORA-27037: unable to obtain file status
  Linux-x86_64 Error: 2: No such file or directory
  

  In my view, that the error may be related to the .dbf file. How can I move this ASM format?

  -Extreme

  It should be ALTER TABLESPACE OFFLINE RBACX without the single quotation mark character.   (I had the character to reach the unknown tbsname).

• Problem with the compatible version of line lock tables

  I tested the effect of locking in the tables in activated version to assess restrictions workspace manager to update the records in different workspaces and I met a locking issue where I can't seem to update different registers of the same table in different sessions if these same records have already been updated and committed in a different workspace.

  I run the tests on 11.2.0.3.  I have ROW_LEVEL_LOCKING worth IT.

  Here's a simple test case (I have many other test cases that are not as well, but understand why it is a problem of blocking will help me understand the results of others my test case):

  -Alter tablespace names in accordance with the requirements

  create table t1 (id varchar2 (36) not null, name varchar2 (50) not null) tablespace XXX;

  ALTER table t1 add the key primary t1_pk (id) of constraint using index tablespace XXX;

  exec ('LIVE') dbms_wm.gotoworkspace;

  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 ('LIVE') dbms_wm.gotoworkspace;

  exec dbms_wm.createworkspace ('TESTWSM1');

  exec dbms_wm.gotoworkspace ('TESTWSM1');

  -Update 2 files in a workspace not LIVING for the update later in different workspaces

  Update t1 set name = name | ' changed ' where id in ('1 ', ' 2');

  commit;

  quit smoking;

  -Now in a separate session (called session 1 for this example), run the following without commit the changes:

  exec ('LIVE') dbms_wm.gotoworkspace;

  Update t1 set name = 'modified' where id = '1';

  -Now in another session (session 2) update a different record in the same table.  The update below is blocked waiting on the transaction in the session 1 to perform (by commit / rollback):

  exec ('LIVE') dbms_wm.gotoworkspace;

  Update t1 set name = 'modified' where id = '2';

  I am surprised, recordings of the different IDS cannot be updated in different sessions which is why is session 1 blocking the update of the 2 folder that is not being updated anywhere else.  I tried this using different workspaces not LIVING with similar results.  I tried to change the properties of the table for example, initrans with and always get a lock.  Changes made to the properties of the table are correctly propagated to _LT tables but not all tables in handler related workspace created for table T1 that precedes.  I don't know if that's the problem.

  Note an example of the query Manager space background likely to 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.

  Hello

  The reason for the block is actually the same as above.  The splits is registered at the level of the version/savepoint, not necessarily just the workspace.  In your example, workspaces TESTWSM1 and TESTWSM2 have a single version and the LIVE workspace has 3 versions.  A new version is always implicitly created during a CreateWorkspace operation if the most RECENT/current version has modified data.  The lines for the id = "1" and id = "2" are changed in each workspace to the child and before creating a workspace.  However, since the id = "3" LIVE online has changed after the creation of TESTWSM1, it is in a different version of those other 2 rows.  So when the updates for the id = "1" and id = "2" are executed, the line is attempted to be divided between TESTWSM1, TESTWSM2 and the latest version of LIVE.  No other line has been updated with this combination so we try to introduce a set of lines in the metadata table.  As this happens multiple sessions at the same time, one of them is obliged to block until the other transaction issues a commit or rollback.

  It is not a way to avoid these LMD.  The lock is acquired in this case is a short-lived transaction lock and they are required for the correct rows be returned for a particular workspace.

  Kind regards

• Create a new line, the prior editing lock

  LCD display 9, Acrobat 9, Windows 7

  Gurus-

  I'm doing a table of observations, and when you create a new line the prior is locked for editing.

  To add a line, I put a button in the table with this code:

  _Row1.addInstance (true);
  xfa.for.Recalculate (true);

  I'm not familiar with the code to browse an index of the table, so don't have no idea how to put in place so that in addition to these two lines above, code goes something along the lines of access = 'protected' to every cell in the previous row.

  Ideas?

  Hello

  First of all, my script was incorrect. ReadOnly must be enclosed in quotes, for example: = "readOnly";

  In addition, you must remove the Row1 readOnly lines and it should work. This is because the reference to Row1 is included in the variable of the bow.

  For example:

  pRow.comment.access = "readOnly";
  

  Hope that helps,

  Niall

• How can I lock the "to:" lines in the window of writing?

  Since the last version of Tbird, when you enter a ' to:' address, as soon as I hit tab or enter, the ' to:' line scrolls to the top and looks that I did not choose an address. But I really, it's just that I do not see the address because it scrolls upwards out of sight.

  With the help of Win8 64-bit Win7 on Sony VAIO mode.

  Thanks heaps for all your help!

  I followed your suggestion to safe mode (which solved my problem) then go back and using the process of elimination to weed out the offending module.

  The Add on the cause of the problem was "Stationery 0.8.4" by Arivald (photo below). I don't remember installing or never using it, but whatever...

  I'm glad to be back to normal again. Extremely grateful to you and the Group of volunteers that run Mozilla. I liked your products!

• During the ETG Table lock

  Hello

  I want to clone a table in our database. Version: 11.2.0.4

  
  Test case:

  CREATE TABLE test_1

  (IDENTIFICATION NUMBER)

  /

  INSERT INTO test_1 (id) values (5);

  COMMIT;

  Now-> I want to start cloning from the table. BUT! After cloning, I must write off line-counts of the original and cloned table. (simple audit)

  To avoid any DML operation during cloning I lock the table in exclusive mode.

  Test_1 in MODE EXCLUSIVE TABLE LOCK.

  -> Now I start the operation of the ETG

  -> DDL's implicit VALIDATION here

  CREATE TABLE test_clone

  AS

  SELECT * from test_1

  /

  -> DDL's implicit VALIDATION here too

  -> Here would be County-parts to start... (The Original County and County of Clone)

  Problem: My DDL statement makes two implicit commits-> first before the DDL and second after the DDL.

  So, in this case the lock on the original table will be released before cloning could begin. --> During a long race THAT DEC can other data manipulations arrive on the original of another session table.

  And in this case if I count the original and the clone table lines I can get a different result.

  Do you know a solution for this?

  -> I can't start a procedure or a second session-> This cloning is done in a DB-Patch which we deliver to DBA.

  -> I can only run an anonymous pl/sql block

  -> In fact, I don't want to use the INSERT INTO (append)... because an ETG is faster and I want to know if there could be a solution for this problem with the DDL.

  I thought to create a trigger on the original table that fires if a DML arrived-> but what happens if a DBA ends the script... then this trigger there. So, I would avoid this change in structure.

  How I could lock the original table so that I can run a DDL in the same session after it without to release the lock on the original table? -> I don't think that would work, but you may know...

  Thanks in advance!

  In fact, I wanted to know if if it was very important how it could be solved. -> In my case, it would have been good to get to know a solution said that maybe I don't know yet.

  A better solution IMHO and the most common way to do it is just put the table in READ ONLY mode.

  ALTER TABLE myTable READ ONLY

  ... do the ETG

  In general, there are many more controls to perform AFTER the operation than just the count of lines. These controls can should be performed by multiple sessions/users for an autonomous transaction will not help you here.

  Reading using only keep data available without him to be changed. You can then rename the original table to keep data online for a period of time or to allow time for it to be saved.

• Can I change the subject line of a message or add a note for my reference?

  I'm still new with tuberculosis after using Outlook for years. In Outlook, it was possible to change the subject line, even though the content was lock. It was nice to put the content in your context, a note, etc. You can do this in Thunderbird or is another way to add a note?

  I think that the Add-on EditEmailSubject would add the functionality you want.

• My verse ATT modem (non apple devices to use this modem} is connected to the ATT line, Time Capsule (iPhones, Macs Time Capsule use) via ethernet Uverse.) Non apple devices can collect data from iPhones or Mac using the time Capsule?

  My verse ATT modem ({use of devices not apple wifi of this modem} is connected to the ATT line, Time Capsule (iPhones, Macs use the wifi of the time Capsule) and connect to the Uverse modem via ethernet.)

  Both devices are set to the highest security and each uses separate passwords.

  Non apple devices can collect data from iPhones or Mac using the time Capsule?

  With a bit of work by someone who knows how to do such things, not Apple computers could read some files on the Mac if file sharing is configured on the network... devices non-Apple and... He knew the device passwords or administrator for Macs.

  Mac could also play the files on other Macs if file sharing has been implemented and the device password or admin was known.

  If you ask if a PC can read the files on the Time Capsule, the answer is Yes, without doubt, assuming that the PC knew the password of device for the time Capsule.

• Qosmio G10-133: the blue lines on screen

  To all those who can help you:

  I turned on my Qosmio yesterday to find a series of unwanted blue lines, distorting the Qosmio logo. Lines and distortion continued until the operating system came at the opening of my office. At this point the whole system locked and the screen went completely blank.

  The Qosmio player suffers from the same problem. The boot system, but crashes when the display is asked to do something.

  I can open the operating system in safe mode, but the lines still appear to a lesser extent on the screen.

  I have run all the tests and has been through the manual troubleshooting section. I tried to reinstall the drives and roll back to the previous facility. But, for all that I try, nothing will change.

  Qosmio my friend did exactly the same thing a month or two it is a. Solution from Toshiba was to replace the motherboard.

  My Qosmio is still under warranty, and I am very happy to send it because Toshiba has one of the best customer service I've had to face.

  But, I was wondering if anyone had any ideas?

  Thank you very much.

  Hello

  I also very pleased with the customer support service Toshiba m.
  I think that the simplest and the best way to resolve this weird display problem is to bring the unit to the ASP. Laptop you is guaranteed to be protected and a replacement is free.

  Good bye

• How to change Microsoft Security Essentials at the request of the parameters of scanning from the command line or in a script.

  Is it possible to change the parameters of the scheduled scan of the Microsoft Security Essentials from the command line or in a script?

  I know that I can use the command to schedule the MpCmdRun.exe tool command line to run, but that do not change or remove the existing scheduled scan that appears in the software. Run regedit to merge into the corresponding registry keys does not work because the keys are "locked", probably by the running of MSSE program.

• 2 phones connected to the same line with PAP2

  Hello

  Is it possible to connect a phone to the first port, a second, and use both in the same line?

  I configured and only works with a single line.

  Thank you

  Yair.

  Hello

  No, this is not the right way. The first port belongs exclusively to recording the line1, second port exclusively to recording of line 2.

  If you want two phones (such as another in the bedroom lounge) ringing on incoming call, simply use the "splitter" to make the phones at the same time and that's it - SPA/PAP Traffic has enough power to operate up to 3 analog telephone devices on each of the ports. I used to have 2 analog phones in parallel on (the only one) FXS ports of SPA-1001 and it works beautifully.

  PS: mae good course use you only 2-wire cable (internal thread) to connect the PAP2T FXS1 port and the phone (s). The 4-wire cable may make some analog phones crashing the device PAP2T IDE oucederomsurlesecondport FXS1.
