• Trigger that avoids "is changing, function of triggering/can not see ' error

  Version Oracle 11.2.0.2

  I have a problem where I try to avoid duplicates in a table using a trigger.  Data looks like:

  EQUIP LO ACCT

  ---------- -- ----

  1000000000 0

  1000000001 0

  1000000002 0

  1000000003 0

  1000000004 0

  Equipment = equipment identifier

  Location = location number

  Acct = account associated with the equipment

  I need avoid the same account to have 2 pieces of equipment are allocated to the same location.

  for example

  EQUIP LO ACCT

  ---------- -- ----

  1000000000 1 1234

  1000000001 1 1234

  1000000002 0

  1000000003 0

  1000000004 0

  I can't create a unique index for this table that when there is no assigned equipment (first example) I couldn't have uniqueness through the location and number.  So, I wrote the following:

  CREATE or REPLACE TRIGGER TEST_TRG before update of test WE acct

  Old SEO AS OLD AS new NEW

  for EACH LINE

  DECLARE

  v_chk number: = 0;

  BEGIN

  Select count (*) in the test v_chk where acct =:new.acct and rental =:new.location;

  IF v_chk > 0 then raise_application_error ("-20001, ' multiple devices at the same location not allowed");

  END IF;

  END;

  /

  .. but of course that I'm shot in the table that is being updated, I get the error of mutation:

  setting a day of test set acct = "1234", location = '1' where equip = '1000000001'

  *

  ERROR on line 1:

  ORA-04091: table xxx. TEST is changing, function of triggering/can not see

  ORA-06512: in "xxx. TEST_TRG', line 4

  ORA-04088: error during execution of trigger ' xxx. TEST_TRG'

  I tried this split into two pieces where a trigger calls another procedure to perform the check and write error, but results were inconsistent and end-user demand does not pick up the error for a reason - it seems to process the transaction very well even if the update was not made at the table level.

  Are there other ways in addition to a trigger to achieve?

  Thank you!

  Then also consider this value in your index of function according to:

  create table test

  (

  equip the varchar2 (10),

  location varchar2 (2),

  ACCT varchar2 (4)

  );

  CREATE a UNIQUE INDEX TestLocationAcct_UK ON Test

  (case when the ACCT is not null ACCT AND! =' ' then location |) « ; » || end of the ACCT);

  Insert test values ('1000000000 ', ' 0',' ');

  Insert test values ('1000000001 ', ' 0',' ');

  Insert test values ('1000000002 ', ' 0',' ');

  Insert test values ('1000000003 ', ' 0',' ');

  Insert test values ('1000000004 ', ' 0',' ');

  Update test set acct = "1234", location = '1' where equip is '1000000000';.

  Update test set acct = "1234", location = '1' where equip is '1000000001';.

  Error on line 1

  ORA-00001: unique constraint (SYSADM. TESTLOCATIONACCT_UK) violated

  Kind regards.

  You don't realize that you have just set a UNIQUE INDEX of several columns?

  create unique index index_name_uq on table_name( user#, upper(item_name) );

• Table is changing, function of triggering/can not see?

  Hello
  I had this error before, and I solved it with the help of this forum.
  But I didn't ask then why is - this error happening at all?
  Now I have it again, with different trigger:
  
  ORA-04091: table TRACKER. APPLICATIONS is changing, function of triggering/can not see
  
  My trigger code is:

  create or replace trigger "REQUEST_EMAIL_T2"
       after update of assigned_to_assigned_id
       on requests
       referencing new as new old as old
       for each row

       then
        for emp_rec
         in (select      username, assigned_email, form_name
            from      assigned, form_type, requests
               where  assigned.assigned_id = form_type.assigned_id
                    and assigned.assigned_id = :new.assigned_to_assigned_id
                    and requests.request_id = :new.request_id)
                  loop

                 p_subj     => 'New Request'
            );
       end loop;
  end;
  / 

  The relaxation will compile without error. The error I get trying to update the table!
  
  I absolutely need to define a trigger as "after" update and need to know how to avoid the same mistake again?
  
  Thank you!

  But I didn't ask then why is - this error happening at all?

  Have you looked at the error message? It is very explicit:
  >
  ORA-04091: table String is changing, the function of triggering/can not see
  Cause: A trigger (or a plsql function defined by the user referenced in this statement) attempted to watch (or modify) a table that stood in the middle of being modified by the statement that shot.
  Action: Rewrite the trigger (or function) so it does not read this table.

  Should this request to join the table of queries ? Does not look like it...

• ORA-04091: table that postal_address is changing, function of triggering/can not see

  First of all, there are any number of TRIGGERS defined on the table in question in our database.

  The process that we have to do is:

  1. load the addresses from the table.

  2. send the addresses by a routine of standardization.

  3. down any address that has been standardized with success and is not already present.

  So, how can I say ODI 12 c to create a temporary table before doing the multicables?  So far, everything I've tried gets 'flattened' and translates into the same error.

  OR

  Is there another solution?

  Thanks for your help,

  Scott

  I fixed that by creating a second physical + sense + model to this same base (not sure if I need all three, but because of this way to make sure).  This caused ODI generate a SOURCE_GROUP and TARGET_GROUP instead of just a TARGET_GROUP in the physical view.  I had to do everything on the properties of the first element in the target, set the properties on the Oracle of LKM Oracle shoot (DB Link). GLOBAL no matter what option I wanted to (USE_STAGE_TABLE or SELECT_FROM_SOURCE_VIEW).  One thing to do is put the database owner SID in the SOURCE_ACCESS_DB_LINK so it does not create an unnecessary DB link.

  Hope that helps someone else!

• Database trigger can not see the package global variable after assign in my form

  Hello

  I faced the problem with the trigger and the package variable global using the form designer

  first of all, I get the local IP address machine using WEBUTIL in triggering of the PREFORM and initialize my global package variable by ' Client_Info_Pkg.Set_IP_Address (WEBUTIL_CLIENTINFO.» GET_IP_ADDRESS); ", then I tried to make the DML operation in my form and at the same time I trigger database also uses the package global variable of" Client_Info_Pkg.Gand_IP_Address; "to read in the package, and then insert it into the audit table

  
  

  The question this database trigger may not feel the initialization "Client_Info_Pkg.Set_IP_Address (WEBUTIL_CLIENTINFO. GET_IP_ADDRESS)' I did in triggering of the PREFORM and I used to wonder if oracle create new session to run this trigger so he can't see my boot or what?!. .

• Accidentally changed the IP address, can not open a session now

  I use vSphere, ESXi 4.0.

  I logged my server via vSphere client. Then on the interface vSphere client, I went to the tab 'Configuration'-> 'Networking' link under Hardware-> "Properties"-> link clicked on change "Network management" on the tab "Ports"-> "IP settings." Then I changed the IP address, VMKernel Default Gateway and subnet mask. Click on 'OK '. After that, my client vSphere lost the connection to this host, I can not connect more using the old or new IP.

  Log error message: vSphere client could not connect with the server 'xxx.xx.x.xx' of vSphere. Details: A connection failure has occurred (unable to connect to the remote server).

  I don't know what these changes mean, I did (was tinkering all around) and want to return to the old IP now. How can I do this through my client terminal? Does not wish to go on the host server physical to do so (but if that's what it takes, how do both?)

  Thank you very much. Really need help.

  -Si DNS is configured, and then try to connect with the ESXi FULL domain name

  -If the material HP or Dell, then try connection via ILO or DRAC, if configured.

  -See if the new or old IP who responded, if yes try to connect via Putty.

• BlackBerry 10 functions and features can not turn off my Blackberry Protect z10 after changing the password ID.

  My wife's phone was last updated the operating system more recent 10.3.2. I then tried to access a service and found when he asked for the Blackberry ID, we had forgotten the issue of password and user. Then I deleted the ID and set up a new. I can connect to the new identification, but he cannot confirm on the z10. Then I thought to wipe the z10 back to factory setting. However; the z10 shows that BB Protect is enabled and we cannot turn it off using the passwords that we try.

  I have logged on to the site of BB Protect and found there is no device associated with this Userid. Also, I find the screen for the current user ID name using our existing email address differs from the one showing on the screen z10 Blackberry ID. name I tried to change the screen name and password on the ID to be similar to the z10 site but it will not accept it.

  So now I'm unable to wipe the z10, or change the ID info to make it usable when required. I also noticed, online, there are instructions for the new OS 10.3.2 informing us that no wiping ability to Protect is disabled. There is no instructions on how to so that when a problem arises like mine.

  Help, please.

  I searched for a solution and I finally found one that works. It was posted by asokhay about a week ago and is as follows:

  "I found the solution!

  I connected my passport for Blackberry link and clicked on "back up and restore" in the left navigation tab. Then I clicked on Factory Reset. He asked me to unplug the unit and when I did the wipe of security has started to happen. "

  This works, however when I wipe the phone it took about 30 minutes. By reading this forum I found that some wipes can take several hours to complete depending on the amount of material is on the cell phone.  As I could not ' t register anything before this wipe I have to start over from the beginning. " Fortunately my wife added very little to the phone, such as applications or photos.

• My Outlook Express set up in my computer by Time Warner Cable is bad functioning. I can not delete/forward/send, messages etc. The messages seem to be stuck.

  No significant change has recently attempted to my computer.

  Go to file | Identities and setup a new identity.  Then, within this identity, click file | Import | Messages and select OE6 format and then your wife's identity.  Then it will import its messages and records should be free of corruption.  Then add the account information of your wife to that identity.  Then make a backup of all 3 identities and once things are working properly you can possibly remove the old and corrupt identity.
   
  See also the points 2, 3 and 6 here: www.oehelp.com/OETips.aspx and here for background: www.oehelp.com/backup.aspx
   
  It is important to keep the messages saved, as OE folders are very sensitive to corruption.

• Changed contrast Assesibilites optionally, can not connect more.

  Hi all

  For some reason any, when I changed the contrast in the accessibility option, my computer suddenly disconnected and since then I could not connect to (I log on, but the screen goes black and it takes back me to the login page).

  I changed the contrast back to normal from the login page, but that didn't help either.

  I tried to log-in through safe mode, but it does not exist on my computer for some reason any... (Dell inspiron N5010)

  Thanks in advance for the help,

  Binam K

  You can get into SafeMode like this:

  1. From the login screen, click the Power Options icon, then hold down the SHIFT key while you click the Restart option. Keep now shift until the screen shows it restarts.
  2. On the first screen that appears, select troubleshooting, and then select Advanced Options. Finally, choose the boot settings and click Restart.
  3. On the next screen, press the number 4 to choose Safe Mode.

  Now that you're in safe mode, you can cancel the bad change with this:

  1. Press + R to show the run box, type RSTRUI and click OK.
  2. Choose a date when the computer was working properly, and then click on next to restore system files from that date.
  3. Check whether the problem is resolved. If this isn't the case, you can return to step 1 to cancel the restore, or try another date.
