• Duplicate values generated by an Oracle sequence

  Hello

  Since a few days we are facing a weird problem in our application where the sequences seem to be generating duplicate values. Previously I thought is this is not possible, but now it seems to be a problem. Here are the details:

  Select * from v$ version;

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  PL/SQL Release 11.2.0.2.0 - Production

  CORE Production 11.2.0.2.0

  AMT for Linux: Version 11.2.0.2.0 - Production

  NLSRTL Version 11.2.0.2.0 - Production

  We use to insert it into a table column of the last sequence value that is of course the primary key of the table column. Today, we received a violation of unique constraint on the column of the primary key (which is driven by the sequence). Below is the last value of the PK column

  SELECT MAX(PCCURVEDETAILID) OF T_PC_CURVE_DETAILS;

  162636

  and below, was the last value in the sequence that has been less than the PK column

  SELECT S_PCCURVEDETAILS. NEXTVAL FROM DUAL;

  162631

  Then we checked the data of the user_sequences and found the next sequence value (LAST_NUMBER) to be 162645 which was greater than the current value of the sequence:

  Select * de user_sequences one où a.sequence_name as "S_PCCURVEDETAILS" ;

  SEQUENCE_NAME

  MIN_VALUE

  MAX_VALUE

  INCREMENT_BY

  CYCLE_FLAG

  ORDER_FLAG

  CACHE_SIZE

  LAST_NUMBER

  S_PCCURVEDETAILS

  1

  1E + 27

  1

  N

  N

  20

  162645

  I then modified the nocache sequence:

  change sequence S_PCCURVEDETAILS NoCache ;

  Select * de user_sequences one où a.sequence_name as "S_PCCURVEDETAILS" ;

  SEQUENCE_NAME

  MIN_VALUE

  MAX_VALUE

  INCREMENT_BY

  CYCLE_FLAG

  ORDER_FLAG

  CACHE_SIZE

  LAST_NUMBER

  S_PCCURVEDETAILS

  1

  1E + 27

  1

  N

  N

  0

  162633

  SELECT S_PCCURVEDETAILS. NEXTVAL FROM DUAL;

  162632

  We also face the same type of problem of violation of primary key to another sequence-driven table, a few days before.

  In our code, I also checked that the primary key in the table value is inserted using only the value of the sequence.

  Can anyone please suggest any reason this issue for

  Concerning

  Deepak

  I faced a similar problem about 3 years ago. Here's the story, suddenly in my UAT environment a job that inserts data in some tables began to throw exceptions of primary key violation. After investigation, I found that the sequence is x, but the primary key for the table is x + y. investigation more - DBA moved all production data without even notifying the application support team.

• ORDER/ALL in oracle sequences

  Hello
  I'm a single instance database running on Oracle 10.2.0.4.
  If I have a sequence created using the ORDER clause, oracle will ensure that sequence numbers are still classified?
  I understand that the sequences will have gaps. It is correct. I just want to know that it will be always ordered.
  
  Is it really important if we use the COMMAND/ALL for unique instances? What happens if we give ALL?
  
  I have read the oracle documentation, and I still have these questions.
  
  Thank you

  Seems pretty clear in the documentation I looked upwards
  http://docs.Oracle.com/CD/B19306_01/server.102/b14200/statements_6015.htm#SQLRF01314
  "
  ORDER specify in order to make sure that sequence numbers are generated in order of demand. This clause is useful if you use numbers in sequence as the timestamps. Guarantor of order is generally not important for sequences used to generate primary keys.

  * ORDER is necessary only to guarantee ordered generation if you are using Oracle with Real Application Clusters database. If you are using exclusive mode, the sequence numbers are always generated in order.*

  ALL specify ALL if you do not want to guarantee sequence numbers are generated in order of demand. It is the default value.

  See you soon,.

  SEQUENCE values always increase; but the gaps that may exist.

  post SQL & results that show the value of the sequence is less than the previous.

• Oracle sequence issue

  CREATE SEQUENCE F_SQ
    START WITH 1
    MAXVALUE 999999999999999999999999999
    MINVALUE 1
    NOCYCLE
    CACHE 20
    NOORDER;
  
  

  I have a sequence is created using the above script. Our night jobs using these sequences, as well on the first day that he used 1,2,3,4,5 and the next day has begun with 21,22,23... and so on

  I understand that's the setting of the CACHE.

  
  Here are the questions

  For three days, it summer jump between the two figures.

  The sequence will never decide to use these skipped numbers? (by above example 6 to 20), if etc. of circumstance and is it possible to avoid it?

  But our PROD servers are running in exclusive mode, which means the sequence will keep producing in ascending order No?... I don't bother about the shortcomings.

  Yes there is no reason why it is not ordered if you are single-instance. But if you want to be sure, just put the ORDER in the sequence. There is no overload when you are single-instance.

• Question about Oracle sequences

  Please let me know if this question is not the subject of this forum and advise which forum I should post it. Thank you.
  
  We have a database 10g running on the AIX servers. A process of data loading was recently, and the development team is of the opinion that the question can be corrupted in the database sequence. This sequence is used to generate a unique primary key for writing in a table.
  
  Are there problems with 10g about the objects sequence database becomes corrupted? If so, is there a Metalink note published on a fix?
  
  Thank you all for a light on this topic.

  Hello

  Interview the max value of your column of tabale, in order to know the populeted of the maximum value of the sequence, compare it your currval in the sequence, and the maximum value for the column. If the values are not the same and the currval is lower than the max value, you will probably have the constraint violation, then increment the value of your sequence curr.

• Sequence increment without a fall

  Oracle 10.2.0.
  
  I need increment a sequence after that I have to perform an import of certain data.
  
  I tried increment the sequence but it takes much too long if the numbers are very large.
  (in the order of 7 digits). We have potentially start at 1, but have no idea of the numbers we are brought into the import.
  
  Is there anyway I can change the sequence without falling and recreate, as it makes my body of package not valid.

  Refer to this.

• ORA-04092 immediate execution may engage in a trigger - Reset sequence

  Hi all. I'm trying to reset a sequence of a procedure that is triggered in a trigger. The reason is that after each new transaction, a new series of point number must be generated, numbering each line as 1, 2, 3... After a new transaction, I need to start from the beginning again. The procedure is
  

  PROCEDURE Reset_Item_Serial_No IS
    
      Serial_No  NUMBER;
      p_seq_name VARCHAR2(20);
    
    BEGIN
    
      p_seq_name := 'SERIAL_NO_SEQ';
    
      EXECUTE IMMEDIATE 'SELECT ' || p_seq_name || '.nextval FROM dual'
        INTO Serial_No;
    
      EXECUTE IMMEDIATE 'ALTER sequence ' || p_seq_name || ' INCREMENT BY -' ||
  
                        Serial_No || ' MINVALUE 0';
    
      EXECUTE IMMEDIATE 'SELECT ' || p_seq_name || '.nextval FROM dual'
        INTO Serial_No;
    
      EXECUTE IMMEDIATE 'ALTER sequence ' || p_seq_name ||
                        ' INCREMENT BY 1 MINVALUE 0';
    
    END;

  This procedure is triggered by the following section in the trigger:
  

   SELECT COUNT(*)
        INTO v_Reset_Sequence
        FROM supply_items s
       WHERE s.requisition_code = v_refno;
    
      IF v_Reset_Sequence = 0 THEN
      
        account_interface.reset_item_serial_no;
      
      END IF;

  I can not use TRANSACTION INDEPENDENT of PRAGMA, the db detects this and restores. Advice, is to make the enforcement procedure, or somehow create a sequence number, whenever I need to insert a new transaction?

  In your case, I'd rather not a sequence. As your requirment is transaction after I'd go with a GTB (global temporary Table).

  Here is an example.

• Reset sequence

  Hello
  
  I created a sequence:
  
  CREATE SEQUENCES ORDER_SEQ.
  
  order of creation.
  
  After that I used it a few times...
  
  How can reset this sequence for 0 again (I can't change the sequence creation script, because it is limited)?
  
  Thank you
  Vinod

  Correct way would be to drop the sequence and re-create it.

  To restore order, you can use script below:

  declare
    v_val   number;
  begin
    select seq.nextval into v_val from dual;
    dbms_output.put_line('Value :: ' || v_val);
    execute immediate 'alter sequence seq increment by ' || ( 1 - v_val);
    select seq.nextval into v_val from dual;
    dbms_output.put_line('New Value :: ' || v_val);
    execute immediate 'alter sequence seq increment by 1';
  end;

• TDATAMAP - sequence of Datakey

  Hello

  Migration of FDM to FDMEE, I combined the two tables of datamaps into one and reset the datakey sequentially.

  Now, however, when I add a new card, I get a "too many objects match the primary key ADF_FACES-60096" error, probably because it points to an Oracle sequence I need to reset.

  Can someone tell me what the Oracle sequence used for datakeys parameter cards to?

• Rights DBA on the sequence

  Hi all
  
  I have a problem regarding sequences, for example:
  
  -patterns 2 (P1, P2)
  -1 seqence (P1. SEQ_100)
  
  Diagram of the P2 has no rights DBA. To add the grant I use GRANT SELECT ON P1. SEQ_100 P2
  
  But when I let it drop and then re-create sequence P1. SEQ_100 normally the subsidy disappears as well. Is there a way which grant stays or is a few different grant that is available (active) on P2 schema, even if we lower and that create the sequence.
  
  Response would be greatly appreciated.
  
  Best regards, Robert

  Well, I expected that you want to reset the sequence, is it not? If you want to reset the sequence, then there is another way! Take a look at this:

• change the sequence currentvalue

  How can I change my sequence so 1'000 ' 000 value of this attribute 'NextVal' would return me now? It is reset to the current value of the sequence. It is possible.
  I see no such possibility here:
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_2011.htm
  
  I tried successfully a this sentence:

  Published by: CharlesRoos on 29.10.2010 16:46

  Hello

  Here's a way, if you can guarantee that no one else uses the sequence for one minute. (Revoke privileges if necessary)

  Find the current value.
  Add 1 to that and subtract your desired value.
  Proceed to the this amount increment sequence.
  A new issue.
  Change back to the original amount INCREMENT.
  The next issue genereate after this will be the value you want.

  For example:

  REVOKE SELECT ON seq_x FROM PUBLIC;
  
  SELECT  seq_x.NEXTVAL
  FROM    dual;
  
  NEXTVAL
  -------
      178
  

  1 000 000 - (178 + 1) = 999821, continue like this:

  ALTER SEQUENCE seq_x  INCREMENT BY 999821;
  
  SELECT  seq_x.NEXTVAL
  FROM    dual;
  
  NEXTVAL
  -------
   999999
  
  ALTER SEQUENCE seq_x  INCREMENT BY 1;
  
  GRANT SELECT ON seq_x TO PUBLIC;
